Yes the front piston skirts on all 4.The lower edge is very thin so I'm going to grind them of and then it won't protrude below the barrrel at BDC.There is no contact anywhere so must be piston rock.It is a track bike so lives at high rpm.

They didn't pick up on the barrels then.
It might be a high rev thing then. I was looking for other people to commission Wesco pistons but didn't find enough people

Engine only wants to go to 12000,no benefit in going higher.Wiseco's and other aftermarket pistons ae shorter too so I may have to replace rings more often with the skirts reduced.
