Hello. when I watched the first video, I noticed a sticker of wiseco, on the lid side covers. and now you say, strangely old head and new piston

[@brianproffitt7263]

What year is this I’m looking at one that looks really similar but I don’t know much about it an I can get it for 200 bucks is it worth it my buddy said it needs a gas tank an a top end rebuild

Brian Proffitt if you don’t want it I do!

[@lukeanderson5781]

Piston clearance is determined by the piston diameter of the skirt. No wonder why the clearance seemed large!

[@dny9394]

Mr Manual he say- A:measure piston and B:cylinder, subtract A from B.
Service limit is 0.120 mm. (piston 12.5 up, cylinder 20 down). Needs re-bore.
