Something broke when installing new belt .

[Kart3d]

Out on the trail and broke a belt we rolled the primary backwards (by hand) to unjam the new belt and something went crunch.

Engine won't start now. I'm guessing the timing chain or something broke?

So what did you find out happened ?

[Bedo]

So what id you find out ?

The cam chain jumped. WHAT EVER ANYONE DOES WHEN CHANGING YOU BELT DON'T ROTATE YOUR MOTOR BACKWARDS.

I'm going to paint an arrow on mine.

Thank you for the information . I would be one of the people that would turn the motor both ways never thinking it would cause a problem.

Yep..I would have done the same mistake to b honest..and I've been fabricating and turning wrenches most of my life...Dam it..

I have read that if you install a manual adjust chain tensioner it won't happen and you won't have the rattle when you first start after sitting a while . Maybe someone could chime in on this.

I've accidently rotated out Rotaxes backwards before will no ill effects, but am going to do same as sweet34 and mark forward arrows on them.....good idea.
