Graves R1 Garage

Got a tech question on your R1? We'll do our best to help out. Get technical info from the Graves Motorsports Staff and Race team. Occasionally one our own Race Team mechanics will step in and take on tech questions that can only be answered by the pros. Lets keep this thread strictly R1 tech and we will get some questions answered. I will also be adding some standard technical advice that is relative to Graves products and/or just plain fun to talk about.

Given the choice and what would you choose and why? A Yamaha Race ECU or a Power Commander, for a track only bike. 2007 model with some engine work done, race baffles etc.

Given the choice and what would you choose and why? A Yamaha Race ECU or a Power Commander, for a track only bike. 2007 model with some engine work done, race baffles etc. There are a few questions you have to ask yourself in this decision and the answers will either justify a Kit box or not. The PC111 is the industry standard so if you go to any local dyno shop you can probably get a decent if not great fuel map for the bike. The Kit ECU kind of leaves it in your hands. I doubt you will have anyone in your surrounding area who is capable of tuning a Kit ECU while dynoing the motorcycle. It is a pretty intense unit with a significant learning curve. So first question. (Question 1) Can you tune this box or do you have someone knowledgeable enough on the box to tune it. If not you might open an expensive can of worms. -Most of the time racers will run a kit box and PC111 so they can use the additional tuning specs of the kit box (throttle position, etc) but for tuning fuel and ign they will still use dynojet. Again it is a standard in the industry. (Question 2) You might need to purchase both PC and kit box - does budget allow and is it worth it to you? - For me to justify a kit box I believe you have to be at the top of your competition. If you are in a high level racing organization and running in the top 5 against a bunch of other racers with kit boxes then you will need that extra tool to tune the bike to that level. If you are not at this level then it might not be even noticable to you. (Question 3) Are you in a racing position to justify the purchase of a kit ECU. If any of these answers do not justify in full buying a kit box then I would strongly recommend getting a PC111 and ignition module and then spend the extra dough on a quality tune and some additional compression (cylinder pressure ;-) Thanks, Taige http://www.gravesport.com

Will a YEC ecu work on a Street bike for Street use? Yes, it will definitely function on the street and depending on the rider ability and tuning it could even benefit but before doing anything look at a couple of the posts I put up earlier in this thread. It explains some details on using the Kit box. Thanks, taige

So the YEC box can be used just like the HRC ECU it sounds. Can you access the YEC ECU thru the stock harness?

So the YEC box can be used just like the HRC ECU it sounds. Can you access the YEC ECU thru the stock harness? You will need a YEC sub harness to bridge between the two but yes....

Thanks!!

Will a YEC ecu work on a Street bike for Street use? No speedo or mileage takes some getting used to - fuel low still works..:lol Taige, I have a set of "standard lift" yec cams (not hight lift ones) for my 05 R1 that cant find much info on. Whats the difference between my stock cams & standard lift yec cams (power wise) ? Thanks Again - Mike

Hello Taige / Beau, I want a full system for my 09R1, it's between Graves and the Akra Evo. How does Graves compare to the Akra?

Hello Taige / Beau, I want a full system for my 09R1, it's between Graves and the Akra Evo. How does Graves compare to the Akra? Both companies build quality crafted products and Im glad to see that you are choosing between the best of the best. Spend the money and buy quality product and you are sure not to regret it. Buy cheap .... not so sure. 1st- and most important to me is power/torque and how it is delivered. Again both systems make great power, and you cannot get perfect comparisons unless you do back to back dyno runs with each systems but our systems have shown a little higher results in most testing that I have seen or heard . Even more important is that they are very consistant and linear with no significant dips and valleys in the delivery. This takes a lot of design time , testing and tuning to eliminate these dips however they make a big difference when riding. Consistancy in power is very imporatant and I believe we have developed the most consistant power delivery in addition to excellent power. 2nd- weight savings Our exhaust systems are the lightest in the industry. Our silencers have titanium entrance, exit caps and even the inner cores are Titanium. For example our full Titanium High mounts systems for the 2009 R1 weigh in at a total of 11 lbs. That is piping, dual silencers and a all hardware. It is exactly half of the weight of the stock system and is the lightest that I have found. Removing weight is like gaining horsepower plus it significantly helps in the bikes handling. 3rd- Aesthetics and Sound This is a tough one because everyone has there own opinion on this. What I can say is we have an exclusive way of packing our silencers which creates an extremely deep exhaust note. I personally do not like a high pitch, can sound to my exhaust. Not saying that Akras sound high pitch but I have heard many systems and nothing so far has given the deep exhaust pitch that ours does. Aesthetics..........Both systems are good quality and nicely made but I like the fact that our silencers are a little smaller on the diameter and tuck away nicely under the tail. For me I like a simple no clutter bike and ours seems to offer that a little better. Like I said you are choosing between 2 well made systems I just think we have the edge on power, weight, and sound. The looks is very personal so you will have to make that choice. If you have any questions feel free to ask me. Thanks, taige

Everyone over here seems to use Akra but i have never seen a Graves system in the UK, why is that??

When are you guys going to have some promotional "give-away's"???

When are you guys going to have some promotional "give-away's"??? Well Im not suppose to say anything but rumor is we are having a promotional give away just as soon as they develop an all stainless steel motorcycle that uses banana peels,a flux capacitor and 1.21 Gigawatts to travel back in time:-) lol No Im Just playin, As of now we do not really specialize in promotional give aways. We support in the ways we feel help more people than just the one prize winner. We developed our Works website to help racers get to the level they need to be to win races, we build quality parts, we tech people with all the effort we can. Some companies spend more time on the promotional give aways then the product engineering. Its a bummer because one person gets a free exhaust and everyone else gets an inferior product. It doesn't make much sense. I would however like to get some T-Shirts and wrist bands in here but that will be down the road. Thanks, taige

Hello again Taige, If i do buy the Graves system for my 09R1 should it be installed using the stock exhaust gaskets?

Taige, thanks for all your help! My shortie Ti system is being delivered today, just in time for WSMC races this weekend! Thanks again! Bengt

Taige, I plan on going with a full exhaust, PCV, ignition module, smog block off plates an magnesium Marchesini rims. Any other easy ways to drop weight and/or add horsepower. Cams? Thinner head gaskets? Cam timing? Just trying to develop a long-term plan with this bike...

Hello again Taige, If i do buy the Graves system for my 09R1 should it be installed using the stock exhaust gaskets? If you want it mint then I would suggest getting a set of 4 news gaskets however.......... you can use the same gaskets and not have any problems. If they were torqued on a bunch of times or the bike had a ton of miles then i would say get news OEM gaskets but that is probably not the case with yours. You could flip them over for a fresh crush on the gasket. Thanks, Taige

Thanks again Taige. I spoke to your UK guy Race Performance Parts today, i'm going to go for the stainless system. As soon as my next pay cheque clears, it's mine!!!! Woo Hoo!!!

Thanks again Taige. I spoke to your UK guy Race Performance Parts today, i'm going to go for the stainless system. As soon as my next pay cheque clears, it's mine!!!! Woo Hoo!!! Good choice. I have run the full stainless on my R6 for the last year and it has been perfect in every aspect. Keep me informed on how it goes and send me a picture for our gallery when you get a chance. Thanks, taige taige@gravesport.com

Taige, What BHP gains are to be expected on my 09R1 when i run your high mount system with aftermarket filter and Power Commander?

Taige, What BHP gains are to be expected on my 09R1 when i run your high mount system with aftermarket filter and Power Commander? Taige....Beau.....???? Can you tell me the above please guy's?

ditto...

Taige, What BHP gains are to be expected on my 09R1 when i run your high mount system with aftermarket filter and Power Commander? Bump???

Taige, What BHP gains are to be expected on my 09R1 when i run your high mount system with aftermarket filter and Power Commander? Stock air filter, Graves exhaust, PCV High mount- 11 HP @ 8000 rpm 8.9 HP @ 11,900 rpm (Peak rpm) Low mount- 11 HP @ 8000 rpm 9 HP @ 11,900 rpm (Peak rpm)

Stock air filter, Graves exhaust, PCV High mount- 11 HP @ 8000 rpm 8.9 HP @ 11,900 rpm (Peak rpm) Low mount- 11 HP @ 8000 rpm 9 HP @ 11,900 rpm (Peak rpm) Thanks Taige, I spoke to RPP again today, he has what i want in stock :) Just one more thing. How come i don't see any of your system in the UK?

Stock air filter, Graves exhaust, PCV High mount- 11 HP @ 8000 rpm 8.9 HP @ 11,900 rpm (Peak rpm) Low mount- 11 HP @ 8000 rpm 9 HP @ 11,900 rpm (Peak rpm) Is that with a downloaded map or a full custom tune?

Is that with a downloaded map or a full custom tune? A downloaded map is a full custom "Fuel" tune. Do you mean , degreed cam sprockets, compression lift, etc. (no extra tuning like thatwas done) These results were from a stock OE motorcycle with exhaust and PCV. Hope this help. If you have any further questions let me know. Taige

I guess what I was asking is, was that PCV map tuned on that specific bike? Reason I'm asking, is there are some local guys to me that have a dyno. After tuning a PCV on the dyno, they are seeing a few more HP than some of the maps that were downloaded. I don't have much experience on this subject, so thats why I'm asking. Thanks.

All dyno's give different answers due too many variables.

After tuning a PCV on the dyno, they are seeing a few more HP than some of the maps that were downloaded. I don't have much experience on this subject, so thats why I'm asking. Thanks. There are so many variables that come into play regarding dyno results. The dyno, the tuner, the room, the temperature, the humidity, the bike, mileage.....you get the point. Some of the things to look for accurate comparisons are- (1) Back to back test comparative test. Dyno the bike with the stock exhaust then, in the same room on the same dyno, with the same motorcycle, do a run with the aftermarket exhaust. This should show accurate gains between the runs. It is very difficult to have one bike dyno test run on one dyno, in one room, with one tuner and then 2 weeks later take the bike to a different dyno, different location, with a different tuner and expect a similar result. Now a custom tune definitely has potential to produce more horsepower than one of our download maps because again you are tuning to a specific set of circumstances which is always better. (2) Avoid the need for a fully custom map. One concept that has recently taken fuel management to another level is the Dynojet Auto Tune. This is one of Chuck Graves favorite new toys for his 2009 R1. This is a separate device about the size of a large pack of juicy fruit gum. It has its own oxygen sensor that you install into the O2 location we offer in every Graves Exhaust system (except the slip ons in which you to retain your stock O2 location). This sensor sends air/fuel measurements back to the PC so that it may adjust accordingly. This is like having your own dyno everywhere you go and a custom map at every turn. TRICK !!! This also allows you to switch between ecomomic and race maps, it will adjust when elevation change occurs, it will base its middle point off of your downloaded map and then adjust 20% up or down to retain correct A/R. This will not only give optimum power but you will get better relative fuel mileage. There is a lot of great features with the PCV and Auto tune. We will have a complete web page describing this in full on our website by the end of the day. Thanks, taige

Looking forward to it Taige!

I understand all the variables when comparing dyno numbers. They start off with the bike running very well off of a map for that bike, and then tune from there. It's always the same dyno, same tuner, I don't know if its the same day/temp, etc, thats going to depend on everyone's schedules. But thanks for the info. I can't wait to gather parts and the PCV w/ autotune, that sounds perfect!

i would like to hear your input about the Bazzaz z-fi with z-afm for a 2006 R1. would there be any gain over a pc3? or any info or recommendation on your part.

i have an 07 r1 with a graves y pipe and graves titanium slip ons. how much would it benefit me to throw on some graves headers?

i have an 07 r1 with a graves y pipe and graves titanium slip ons. how much would it benefit me to throw on some graves headers? The header design can defintely add some significant performance in all the right areas but unfortunately you cannot fit headers up to the cat eliminator system. the sizing and connection points are different. You would have to sell the CE and get a full. It is worth it if power is your main consideration. Thanks, taige

i would like to hear your input about the Bazzaz z-fi with z-afm for a 2006 R1. would there be any gain over a pc3? or any info or recommendation on your part. can i get an answer or some info emailed to johnblaze11@aol.com or even pm. help Graves

can i get an answer or some info emailed to johnblaze11@aol.com or even pm. help Graves Here are my thoughts on Dynojet vs. Bazzaz..... Both companies build a quality product....both companies have great engineers and good technology....... however there is one items that puts Dynojet up on top. It is the industry standard. The parts, service, dynamometers, fuel maps.....basically anything you need or want from them is extremely easy to acquire. With one phone call, email or trip to an authorized dealer and you can immediately fix any problems or tune for power. It has been tested and tested for years on the street and everybody knows Dynojet. With all of this testing, come reliability. They have spent years and "working out the bugs". Bazzaz has been around for a while however when you talk about Dynojet you are talking about tens of thousands of riders using the product over the coarse of years and years. They are very connected to the street rider and racer alike. Not saying these are reasons to choose one item over the other however they are important. Ask yourself 3 questions. What is most important to you in choosing a fuel management system? If you just want a reliable unit that will allow you to remap the bike easily go Dyanojet. If you are looking for maybe some additional features like traction control then go with Bazzaz. What are you using it for? If you are running around on the street ....at this point I would suggest the DJ unit simply for the fact that it is proven very reliable and almost every decent mechanic knows how to work with Dynojet products. If you are racing the bike and then both companies will get the job done, It is a matter of what are you and your mechanic use to working with ? What level of skills do you have? I would estimate that 9 out of 10 tuner shops know how to use Dynojet products, in fact a majority of them probably have the DJ dynos in house. Bazzaz is growing but you will not have as many tuners familiar with that product. If you are low on the level of mechanical skills and you just want to download a map and install the unit onto the bike.....and not have to think about it for a long time. Just ride.....I would push you toward the Dynojet. Either way.... like I said both companies build and design quality product....however just for the fact of it's proven reliability, household name in tuning, and the easy to use components I would edge toward Dynojet. Thats what I have run on my R6 and it has had 0 problems. I feel confident about going out for long rides and if anything breaks it probably will not be my Power Commander. (2 knocks on the wood of my desk). I am still working with a PC111 but very soon I want to move to a PCV....I have been learning about it and hearing that it is really advance incomparison to the PC111. Thanks, taige Thats my belief for now. Thanks, taige

I have a set of your valve springs for a 2001 R1 is there a way to test these to see if there are all equal pressures/spring consistency ?

I have a set of your valve springs for a 2001 R1 is there a way to test these to see if there are all equal pressures/spring consistency ? Absolutely. Using your valve, retainer, keepers, spring base and a caliper you can find installed height of the spring. Using a spring tester you can find seat pressures, pressures at the nose of the cam, coil bind etc. There are many shops that will be able to do this for you. Thanks, taige

Hey guys I was lucky enough to get a killer deal on a set of your beautiful adjustable rearsets from a friend of mine who was parting out his bike. HIS R-1 is a 2008 model, MY R-1 is a 2004. I noticed just by looking at the sets that the brake side is different than mine. The existing bracket for holding the brake master is on the rearsets is vertical where my 2004 model brake is horizontal, the master mount holes also appear to be too close together on the rearsets to mount my 04 master. Is there a 2004 bracket and brake pedal for the adjustable rearsets that will accomidate or do I need to adapt a 2008 master? Also have a set of Forged Marchesini..he he he....to mount up but after stringing the bike and measuring up everything it definitely seems I will need 1/8th inch spacers for each side of the wheels front and back. Any ideas on either of my quality problem dilemmas will be greatly appreciated. I will be seriously updating my goodie list for the ole R-1 soon, oh yeah did I mention the Ohlins steering damper and Graves barends too? Thanx in advance, Chad

The marchis will not be too difficult to space up and install. If it is too complicated you are welcome to send the wheels my way..... ;-) Email me over at Graves so I can go into detail on these rear sets. Plus I need to invesigate how you can make this happen.

Just had my O7 to the shop for a power upgrade. I was planning on going with the pcIII or bazzaz tunning. My tuner has brought some issues to my attention with the 07 not using 100% throttle thru out the rpm range. he has called dyno jet and they have told him to contact Graves. What can be done to over come this issue?

Hi, Great thread!. I have an 06 R1 used purely in competition. I'll focus on motor changes here as that is where my questions centre. Firstly it has a full graves exhaust system, YEC Kit cams and springs, YEC T=0.30 head gasket, YEC ECU and harness. I'm in a rush to give her a refresh and trying to line everything up to get it done between rounds but parts are a problem for me and I'm thinking about compromising, which worries me greatly. Could I use standard valve springs with these cams? I can't find YEC springs anywhere. All i can seem to find is a t=0.35 YEC head gasket. If i use that, will i lose a lot in terms of compression? I've ordered the same colour bearings but will changing my head gasket mean i should consider changing bearing sizes? I've lost my software cd that came with ecu and the data link cable. Got any ideas about how I could 1. find a place to buy or find either 2. or another way to connect to change mapping after rebuild and do some dynoing? Any suggestions would be greatly appreciated. Thanks again!

I got a 03 R1 and gona do some power mods this winter using some of your parts. 1 -My friend is a trained mc tech and said to look for adj cam sprocket - is this what i see listed on your site for my year r1? 2 - slide stops - what exactly is there function? i am a mechanic myself but not sure what these do. Is it a good power upgrade with k&n yosh slip on? do u supply the map needed for the PC3? 3 - V stacks on the list too - port/polish rounds out the off season upgrade list. Think i'm gona scream in my helmet next spring? Thanks guys

X2???:dundun: The bike will only read 90% throttle on the dyno at certain RPM's. So at wide open throttle the dyno will only register the 90% limiting the tune. When we called dyno jet they sent us to Graves. Now when he called graves the guy there said he would shoot him an email explaining what to do because he could not talk about it over the phone! WTF????
