trx 250r just quit???????

[jimbo1073]

while riding 2 weeks ago my r just quit.
1.changed the plug 2.cleaned the carb 3.checked the reeds
4.checked the compression(205 psi) 5.changed the stator
6.changed the coil 7.changed the cdi 8.no cracks in the cylinder
its getting fire at the plug but will not start.not even if i pour gas in the plug hole. i removed the head and there was no damage to piston or cylinder visible.
the head gasket was leaking antifreeze( tiny bit) on the outside of the head. there was also alot of pressure in the radiator

If it's sparking and has compression, the only thing left really is timing. Woodruff key was in good shape? You've made sure the new plug hasn't fouled from too much gas?

didn't you post this a week ago? If so - I told you back then to check your woodruff key because it's probably sheared.

You getting backfire when you try to start it?

[jimbo1073]

not backfiring . did once before but hasnt anymore. the woodruff key looked fine.

[Saul76]

well - timing seems to be the only thing that would keep it from starting going by the info you've given.

Got the killswitch 'on' ? lol

long shot here, but you might check and make sure your silencer didn't come apart and block off your exhaust for some unknown reason.

Yeah this happened to me and cost me a race and two spark plugs before I figured it out.
