realy wow thnx that nice to know i dont have it at home yet but the guy said he thinks it jump timing would that screw up the top end?

[lndy650]

if it jumped timing then there is a possibility that the piston hit a valve which is bad but its possible nothing happened and its just off time. the only thing is if you put a new topend on it and a streched cam chain is the problem then it will just happen again... i can explain how to tell if its off time if you need help with that

Do a search on the forum for a service manual. It'll explain everything you'll need to rebuild the top end.
