[QUOTE="r.2 stroke, post: 330130, member: 27248"] For anyone that maybe interested!,i got my cylinder and a couple of pistons measured at a machine shop that has a good reputation. Bike is a dec.'99 220r done 130 engine hours(blame the low hours on work!),with an 'A' cylinder(sorry to rub that in again C-carvr!!)Air filter always in good/clean cond. Cylinder measures 69.02084~69.03084 mm( on thrust face) 'C' piston,with 40hrs use measures 68.8975 mm My 'C' piston/cylinder clearance = .123~.133mm New 'M' series Wiseco piston measures 68.95084mm My wiseco piston/cylinder clearance = .070~.080 mm recommended piston/clearances:OEM= .079~.089 mm Wiseco= .064 mm Foot note is :that i thought that the wiseco may be a little tight in my 'a'cylinder,but it is o.k. Piston/cylinder clearance with oem 'c' piston was larger than i thought would be. Wiseco 750m series,replaces 750ps series piston. :cool: [/QUOTE]
