2007 yz450 won't start after warned up?

nope...brand new valves with seats recut....yz450f's dont have tappets...


Yes they do.  "Bucket" tappets over each valve.

greyracer...parts list refers to them as "lifter, valves"...ive never heard them referred to  as tappets.....live and learn.....more excited to see the poist explaining the stator was the issue....

Tappet, cam follower, and lifter are synonymous and generally interchangeable terms.
