need help troubleshooting: problem with bike starting after drive.

[underconstruction1998]

I was told about some cbrs having a recall on the stators and fly wheels. but when i called and gave a dealer my vin # all was good on my 08 cbr1000rr. i keep my bike hooked up to a little trinkle charger (during winter months) that they sell for motorcycles (not sure of the brand). the problem im having is after i unhook the charger and get ready for a drive (motor cold), my bike starts up just fine. after i drive it or even if i just leave it parked and warm up to normal driving temps and then turn it off, when i go to start it back up it acts like the battery is dead. i will have to try several times but sooner or later it starts and drives just fine. i put a meter on my bike battery: with the bike off and not on charger for 2 days the meter read 12.3 volts. then i start the bike just fine and for 10 mins while my bike was running i checked the battery all voltage readings were between 13.9(after it warmed up)-14.6. and after all this i shut off the bike waited 5-10 mins (enough time to go in a store and pay for gas). i check the battery and its still a good 12.7 volts. but when i try and start the bike it acts like the battery is dead. after trying several times like i said before it starts. can anyone help me troubleshoot this problem?

I'm no mechanic when it comes to motorcycles. I wouldn't even be giving this advice if the problem didn't sound familiar to a problem that is common with cars. It sounds like your starter is going out or you are not getting enough voltage to it i.e. a bad connection. I could be well off base with this but it is where I would start. I'm sure that some of the more experienced motorcycle mechanics will be able to tell you whether I'm close or way off, as I'm sure you know there are some smart people on here.

Pull out the battery and take it and have it load tested
this will confirm a bad battery. From the numbers you posted
my guess is your battery is toast

Does bike start right up after a ride when it's given time to cool off?

As above load test the battery to see if it is holding over a 5 second period.Then it can be ruled out.

Sounds like a bad battery.

thanks everyone for the fast replies. i will get the battery out and go get it tested. will reply again if thats a fix. answer about if the bike will start again after a ride and time given to cool off. the answer is no. not without putting the bike back on the charger.

if it's a bad battery, why would it start after multiple attempts? Just saying.

I have major stereo components in both my cars, which = sucks batteries dry. both my cars have started with under 12 volts. 12.3 volts should be plenty to start the little 4 banger in the 1krr.

I hope it's the battery b/c that's cheaper than the starter. my bet is the starter or something else. and man up and get a lithium battery, then you won't have to trickle charge it in the winter .

Batteries last 3 years regardless. Bad battery

I think that's awesome. Makes me feel layered.
