Mistiming at high revs

Recommended Posts

i own a 2001 wr250f and when you reach 3/4 to full throttle the engine will begin to mistime which is accentuated by the exhaust, is this a regular problem in WR's or something more major thanks guys

This can happen at higher RPM when your iginition is not doing it's job. Make sure you have a fresh spark plug.

Also an improperly sized main jet can cause this. What is the size of your main jet? Most people run in the 180 or 182 range depending on their mods, altitude, temp etc.

If this doesn't cure it then you can go back to suspecting the ignition. If you've a mate with the same bike, try switching CDI's and see if that clears up the problem.
