Bike wont start when hot

[elton_t]

Is this usually a starter problem when the bike wont start when HOT?? even when I wide open the throttle it still wont start. Only if I accidentally stall the bike, it will be able to start it back up with a slight throttle.

If I let it sit until it has cooled it will start no problem(always with a slight throttle twist).

dirty starter? clogged carbs? valve?

i have checked the battery,
12.94 when stationary,
12.33 idling,
13.6-7, max 13.9 when going over 5000rpm.

so a bad battery or rectifier is out of the question

i have no idea whats wrong..

Even though the battery is fully charged it could be a bad battery just a thought. I am having a problem with mine starting and i think it is the battery i hope at least

190F - 224F is high, for the temperature. did you check the Coolant ?

i just did coolant flush last week with engine-ice. it should still start even at 224F, it never goes higher than that.

Ok.. i just went ahead and try to start it again. it started instantly. wth?

the colder my bike is, the more likely it seems to start! only when it gets warm, so whats the deal here?

if it spins over fine?

when were your valve clearences last checked?

long shot i know and the last thing to look at but if the clearances are a bit tight cold, when hot it can hold the valves open and make starting a pig.


hope this helps
