mine hates starting if its about 220F but eventually it does start

 

Trying charging the battery and see if that remedy the problem.

 

I've had random starting issues with my bike for as long as I can remember. At first it was constantly having a low battery and a slow starter. So I replaced the battery with a Shorai and a tender and all is well (except in the winter). But every now and then it seems like when I start the bike, the starter will cut out momentarily then springs to life. Happens few and far between but very strange nonetheless. I always wonder if it's my alarm install, or HIDs, or PCV, or SpeedoDRD, but I can't get myself to go through it all to double check everything.

 

seems to be a weak battery, get it checked..

 

STARTER MOTOR!!....delamintaing magnet, had random and inconsistent starting issues for most of the first year i had the bike, went through 3 batteries and after getting a new starter motor, it fires like a champ no matter the conditions. The mech showed me the old motor (the bike was only a year on the road, left over 09), one of the magnets came loose and was on occasion jamming the armature causing the inconsistant starting/killing of the battery.

 

I was afraid of that, haha. I guess I need #1, the expensive thing.

 

If you have the original battery its time to replace it. I had the same issue where I would start the bike cold and after it was warm it wouldn't restart. I got the MBTZ10S MotoBatt Quadflex Battery, very happy with it awesome battery! The bike starts now on the 3rd crank.

 

i think ill need a start motor soon. i could ride and then park and 5 mins later trying to start it will seem like if the bike is starting from overnight storage. but sometimes it starts right up. damn amp hog. i need to get a new startor motor and then pair that with a Shorai

 

It's a Japanese engineered motor vehicle, so it should start quickly and consistently in almost any condition, otherwise you should figure something is amiss. If it was made in Italy, then it's just normal

 

warranty on the late model bikes?

 

:fork5 year extended:flex:

 

my bike sometimes takes a while to crank over aswell especially sometimes when i stall it but yeah mostly when its warm.. i dont know why.. are we even talking about the same problem? my bike only has just hit 7,000kms aswell (4,300) miles?

 

I believe they call that starter soak. The starter gets hot and the internals expand enough with the heat to cause friction and it won't start. Had a friend years ago that decided to take the heat shield off the Camaro he had when he changed the starter.He had installed headers and without that shield the starter would get heat soaked and it had to sit for 20-30 minutes to cool off. Then it would start right up. On something that new...with an internal starter,I would say there is something wrong/defective with the starter. Of course I would first have the battery checked to make sure it's good. Far easier to get at the battery and cheaper to replace.

 

make sure the battery is at least 75% charged and do an amperage test on the starter with the engine hot. also check the wiring resistance between the battery and the starter. check the ground. but if your battery isnt turning the engine over hot and a jump from a car battery will, i would put a load test on the battery to make sure it is good. you may have a bad battery or worst case a charging problem.

 

My 2000 experienced no start or hard start hot only,that would be the starter. I relaced the brushes and it was good as new. My '06 had the same issue,i replaced brushes it was good for a little while then acted the same. Installed a Ballistic Evo2 12 cell that has 410 cranking amps versus 190 for the stock battery and it fires up faster than new,you can definitely hear the engine crank faster. So IMO for all of you having battery or starter issues the Ballistic 12 cell will cure both problems with just a battery replacement only ,eliminating pulling the hard to get to starter ('00 is easy '06 pain in the asz)

 

Hi Guys, was this problem ever solved?

Was it the Battery, Starter or Valves? I'm having identical problem with a 2000 model also

 

Remember, a 12 volt automotive battery that is holding a 12 volt charge is 50% discharged. Not many people are aware of this fact.

 

Sounds like the starter to me, its mounted right on the motor and when hot the copper inside can expand a little making it harder to spin and make good contact. Id rebuild the starter its fairly cheap and good way to test. Waiting 20 mins doesnt mean anything to the battery which isnt really affected by bike temp. Also iirc that chart is for lead acid batteries not AGM, fully charged AGM are about 12.75 I believe

 

I suspected the starter too but when i connected a car battery using jumper leads the starter was spinning fast enough for it to start. So now back to square one.

Its been really bad lately, wouldn't start at 60c or above, I messed around with some wring, unplugging and plugin things, check compression, on one cylinder only since my gauge would only fit number two, hot/cold where the same pretty much. I managed to get it started at 80c couple times which i could never do before.

Could it be a sensor, coolant or engine block temp sensor? I did unplugging and plugin coolant sensor not sure if that helped with starting at 80c

 

forgot to mention when i was doing compression test cold the gauge would jump to 70 and stay at 70 as im cranking it over but hot it would jump to 70 then drop to 50, it did that each time i crank it over when hot. from 50 jumps to 70 then back to 50

 

This is a problem^^^ sounds to me like you definitely have a valve problem or the shims really need to be adjusted. How many miles do you have and when was the last adjustment or check done?

 

Thanks Zac, will give that a go. what about when I connected the car battery it still didnt start.

bike battery is 220CCA, car Battery 270CCA both connected and still didnt start

 

A lot of ppl don't realize just putting the 2 battery's together you don't gain much at all. Actually they don't like to share energy to the next until one drops volts but it's slow!
You probly only gain about an 1/8th of the cranking amps when drawing power.
You got to think of it like this it's designs to hold energy not share it, and a generator or alternator supplies voltage that's why jumping cars works you got something pushing a load not trying to pull one from an even power source

I know what you mean. I was going to purchase a second batt but when the starter spun nice and fast and bike still didnt start i thought cant be battery.

current battery 220CCA I purchased no more than couple of months ago. when i first purchased the bike and the owner dropped it off with a dead battery so first thing I did was buy battery.

 

Haven't had a need to do a compression test in a while but shouldn't it be more like 150?

 

Should be up around 190psi

190wet right?

 

Yea you got it! And spin it until the gauge stops going up.

I have a 05 R1 and it gives me the same problem. I replaced the battery thinking it would change the situation but its still the same. The starter hardly turns the motor when the bike is warm. Almost seems like the battery is dead. I wait for a while and then give it a try and bike starts fine after cooling off a bit. One more thing I noticed that the battery terminals become awefully hot while I start the bike when hot. I think its the starter. It probably needs cleaning or replacement. I don't think its the battery.

 

"One more thing I noticed that the battery terminals become awefully hot while I start the bike when hot"

sounds like the starter to me, as the brushes wear they draw more amps to make the same connection. Over time this puts alot of stress on everything and it gets to a point where it just draws so many amps the battery cant keep up. With the starter being mounted to the motor the way it is it gets very hot which makes the electrical connection worse as it is. Id do a starter rebuild then report back...how many miles btw?

 

Errrr sorry didn't note the miles

 

Did you manage to find a solution to what the problem was ? I am having the same issues with my 09 R1.

Changed the battery new cheap ass one with 130CCA but still does the job. Mottobatt rates their equivalent to the OEM Yuasa for 140CCA anyway.

Had her fully serviced shims and valves adjusted.

A couple of days ago on a 1-2 minute stop for my mates to refuel she would start and then choke. While I was trying to start her again I tried to rev the throttle just chocked her faster. After that I switched the key to off and then on again she started straight away. At first I was afraid to turn her off but after idling for about 30 secs I switched her off. Before that she was sitting at a show for a couple of days and we headed for the gas station in a slow pace driving for about 5km or so.

Maybe she just needed that extra minute or so to cool down ? It's not the first time and I am afraid won't be the last. It seems to always be around the same conditions and variables that this happens.

It's a very strange situation indeed and very frustrating..
