Prox Piston Clearence
I have a seadoo gtx 2001 std bore.I have been using WSM Pistons and they come 87.91mm.Now I want to try Prox but prox is 88MM. Can I use prox 88m on my std bore.Do I have to bore cylinders?

You have to measure the actual piston and cylinder and determine if the clearance is correct.

.006 at the skirt is normal for Pro x. Wiseco .007-.008 as they expand a little more

It is very unlikely that you will be able to run stock bore pistons 3 times with the correct clearances-- stock oem pistons (1st original top end), wsm stock bore pistons (2nd top end) and now you are going to prox stock bore?
