First question, rode the bike and noticed it leaking some oil. Saw some other posts said it's probably over fill issue. Any way parked and hav'nt rode for over two years. Finally want to start riding again and can not get it to start at all. So I pulled valvre cover to check valve clearance. Could not even get a feeler into the intakes at all. So pulled camshaft and found each valve had a shim of 1,7 under each bucket, After reading everything I can find, 1.2 is the smallest shim I can find. just wondering what else I might look at before buying a complete shim kit. What would make the valves so tight? Any help would be great.
