250r no start

[rrguy]

Any help with

Gas yes
Sparke yes
compression yes
timing on it seems

Was starting on first or second kick, was tuning & bogged a bit & now wont start.

I would start out by replacing the spark plag just becouse it will fire outside the head does not mean it will fire under compression. If you were tuning you probably fouled the plug. How did you do the compression test? Make sure your air intake is clear of obstructions and that the exhaust pipe is open as well.

i second the sparkplug

[atvmx_freak08]

Pipe/Intake have gotten me a few times, make sure they're both clear and free flowing. I also agree with a new plug.

try hitting your CDI box with a handle of a screw driver also, i've had that happen theres spark but it might not aways be enough or right or something i dont know the dea...

[rrguy]

yeah I had swapped plugs & even went out an bought another new one.

new gas, swapped cdi swapped coil? checked stator & timing plate?
