Good luck! They can take a relatively large overbore but I think 83.5 or 84mm is the highest you can get.

Must be one of the later ones. Lucky though and one less job to do. At least they come with the oil squirters and saves me having to rebore hopefully so long as the forged piston clearance is OK.
Any recommendations for the replacement main and big end stretch bolts?
