1mm OS Pistons
Posted: Sat Jul 23, 2011 7:04 pm
Got a bike in from a friend at the moment and the crankcases are pressurised:oops: lots of oil in the airbox.. He's had the bike rebored to 1st Os already so I'm expecting to find its not been done correctly. 
I may need to goto 2nd OS and just in case has anyone got a set of 2nd OS pistons? new or used?
