Ok, so I'm nearing my wits end.
I have a 2010 Yamaha WR250R. Full exhaust, fmf programmer, and gears. I recently washed the bike and ever since then the bike hasn't cold started.
The bike will not cold start at all but will crank all day, if I push start the bike it starts right up but if I don't let it warm up it will stall. Once I let the bike warm up, I can turn it off or let go of the throttle and it will idle just fine as I adjusted the idle, but the second I go to start it up it will crank crank crank and when I twist the throttle all the way then it will start sometimes but still after hesitation.
I really can't start the bike without twisting the throttle but after the spark plug install I noticed I can get away with it sometimes when it's super warm by just pushing the start button.
I have replaced the battery with a brand new ytz7s 130cca battery
I have replaced the spark plug with a brand new cr9e spark plug
I have put brand new premium fuel in the gas tank
I have cleaned and opened any airways that may have been obstructed
Only thing I have left to try is to remove the fmf programmer cause maybe it shorted when I was washing the bike...Other than that, I am at a complete loss.
Any suggestions would be amazingly appreciated! HELP!
