CRF's Only Forums

Hi guys got 09 bike covered 40 hours and developed fault, won't start with electric start, just turns over till battery dies, I've checked valve clearances, new plug and full service etc, starts no probs with kick tho?

Any ideas guys??

welcome to CRF's Only. verify your auto decomp is functioning correctly. if so, a weak battery will not spin the motor quickly enough to start. if battery is strong you may have a starter that has bad brushes or worse.

Thanks for the welcome. How do I go about checking auto decomp is working?

inspect it. check the spring and weight. pull the spark plug and with the valve cover off rotate the crank one or two full cylces and see if the decomp is functioning.

Hey! my ´04 250x won´t turn over with the electric starter, actually when I press the button it sounds like if the battery is drained out but it is in good shape, charged and holding voltage correctly also checked if alternator is charging correctly and it is and reg/rec is working properly too, so it only makes just like a click and won´t turn over, then with kickstarter it starts but after a several tries and only with the throttle fully open and choke open too, but when closing choke it dies.
what would it be the problem?
Recent history
Bike was running well like a month ago, that last time my clutch cable broke since it was incorrectly routed and to get out of that trial I exchanged gears without clutch, then I installed a new clutch cable and changed oil, transmission oil, cleaned air filter and oiled it, adjusted chain, cleaned and lubed, cleaned bike. And this last time I tried to start it, first time it started perfect but died right after and weirdly a lizard came out from the exhaust! then tried to start the bike and started this problem, it sounded like the battery was drained out only making a click and hardly starting with kickstarter and then dying if closing choke or trying to open throttle.
Any idea is very appreciated.
