Please help and sorry for my spelling and grammmar

double check your slide, sounds like it is in backwards. very easy to do.

if not the slide in backwards then i bet its a clogged slow jet. same thing happened to me!

Plus check your hot start lever/cable.

And your pilot air jet in the carb bell.

crf450panama when are you comming to cycle ranch again?

Happens to me everytime I eat White Castles :D, bike runs okay though.

Sorry I couldn't resist. :)

Check the plate on the front of the slid. Might be in upside down.
