Motorcycle Questions? Ask a Mechanic.
are you doing the repairs your self or will you be paying to have it done
a rebuild kit is about 150 dollars you would need to change all gaskets and seals flush out the engine
in deed you would have to reset timing as well as sync the carburetor
yes its tough to do even for experienced mechanics your looking at about 300 dollars to have it done
not a problem if you need anything else please let me know if you need anything else and be sure to rate my service when you get the chance
