Piston and sleeve from RB engine
Hello there,
I got from a friend of mine a new set of piston, sleeve and con rod for an RB engine as he said. It is from a .21 short stroke. The con rod has engraved "XS" on the big end and the number 10 on the small end. Judging from the photos can anyone tell from witch exact RB model it comes from? Thanks for your help.

RE: Piston and sleeve from RB engine
Looks like an s7 or possibly an earlier WS7. The later ones has M.E.S. exhaust ports. Also the conrod looks the standard conrod not the competition one but hard to tell without seeing the top half of the conrod. If it is the standard rod then it is most likely the s7.
