02 450R no start

Recommended Posts

Yeah, the valves are tight, and I plan on replacing the with SS, but I was wondering if that is enough comp. to start and run. It has spark and fuel.

YOU NEED A SERVICE MANUAL

 

The auto decompression system will not allow you to do a full compression check.  It will only peak at about 60psi.

You need to do a leak down test, but more than likely, you just need to rebuild the head.

If it pull/bump starts and then starts fine, it's for sure the left intake gone completely bad.

And check the cam timing just to be sure it's not off a tooth.
