WSM Pistons

[Master of Faster]

Has anyone had any experience with WSM pistons good or bad. I'm in need of a rebuild and I can get the entire kit for a reasonable price and just wondered if anyone here has run them and what they thought. They are WSM Platinum Series and are supposed to have a low friction coating, any input is appreciated, thanks.

Kind of a long story but I put a set of WSM pistons in my shee when it was cut to 10 over (you can't seem to get a 10 over Wisco Kit). Anyway, at the time they were using snap rings instead of circlips. I lost one on my left sid on my second time out. I called WSM and they said to send them the cylinders and they would make it right. Well, as I was only at 10 over I expected them to sleeve the messed up side, but instead when I got my stuff back they were cut to 40 over with a new set of those exact pistons you are looking at. Anyway, when I finally got around to using this top end (about a year later) I started measuring it prior to final assy only to find that they had cut the cylinders to .006 clearance on one and .0045 on the other. To make a long story short, I ended up buying a set of 50 over Wisco and cutting the cylinders again. As far as I am concerned, WSM cost me 4 bores and a lot of time. Make what you want from this info, and if you are intersted, I have a brand new set of 40 over WSMs for sale. :-)
