Starting Problems???

[RAPTOR80RACR990]

I have a 07 450R, and it will crack and crank but it just won't start. But if you drift start it and it starts everytime..whats the problem???

i dont know know what drift starting is but it sounds like your intake valves are to tight

Have you tried pumping the throttle 5 or 6 times berfore you crank it?

check valves and most important decompression specs. my 07 did that after i put a cam in.

drifting when your buddy pulls you so fast your back end is stepping out. you drop the clutch and it fires right up. ya your valves are tight.
