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

Graves Adjustable rearsets

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. Thanks, taige

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!

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????

Graves dudes,

Did you guys remove the top "secondary" disks on the throttle bodys on your 04-06 R1 racebikes back in the day ?

No, In fact we used them to tame down the power at small throttle openings. The kit software allowed us to adjust the position of the secondary butterflies. (TPS over RPM) Worked great! the riders thought they had traction control.

Thanks Chuck,

Been a big debate here going back YEARS about leaving in the top secondarys or taking them out on the 04 generation R1.

Out seemed to quicken the "power hit" imo.
