Brought Remy in for a tune up and ended up taking the whole engine apart. Primary chain guide was brittle as hell, valve seals were loose, and piston rings need replacing. Still waiting for word if parts can be brought in from Japan since they're not available here.
Talked to the mechanic and he said we could fabricate the needed parts in case Japan can't deliver. At least that's some good news. Hopefully the fabricated parts will work as good as the original ones. Can't wait to get her back on the road again.
Good luck to me.
