If the key is sheared, make sure you lap the surface of the crank perfectly smooth again, otherwise the key will shear immediately the next time you try to start it. I only know from experience.
So key looks good as well as valve clearances. Still no luck ....I'm almost losing faith in this bike (Not Gas Gas altogether, cause I know the newer 4 strokes have the FI setup correctly).

Any other ideas guys? I turn the key on, the fuel pump primes up and makes the sound, I hit the e-start and the motor turns good and it goes *bump**bump**bump**bump* and wont start.

What I still haven't done is a TPS reset, and probably other things. I replaced the spark plug this year, but maybe I should get a different model? CR7A or CR8A? Any thoughts or other suggestions?

Thanks for all your help
