Possible, it’s a jap import so could have been sitting for a year or more… thinking you’re going to say gummed up rings? If so I like the idea…

Hmm, thanks. It’s only done 15km (apparently), is that typical or pointing to heavy thrashing or poor maintenance..?

Hi, just got a project bike running and it's smoking a little. I thought I'd wait until it's ridden to see if the smoke clears to indicate stem seals or valves. In the meantime I’ve checked my compression and it’s reading 105-110 across all 4, the manual says it should be 142-199 and that 114 requires attention (*crap). The apparent test to see if the issue is rings or valve related is to put a teaspoon of oil in, which I did in number 1 and the figure went up a little to 120. Does this sounds like rings or valves or maybe both? I guess I can refurb the head but then idea if all that work and reassembly to find out it’s still low sounds like a pain… Thoughts?
