WSM pistons and top end rebuild kits
Looks like I'm going to have to rebuild the top end of my 780. Anyone have any opinions on WSM?

I have bought WSM for a few rebuilds and I had to replace one for a lean issue so I got one from my Hero Beerdart ! when I went to weigh it it was the same exactly as the others and it had to be many years apart they also measure out nicely so my point being
I think they are high quality!

Tony, get the cyls first. Then you'll figure out what size to get. You can score the kits off Ebay for under $300 shipped.

I'm sending the cyls out to a local machine shop in the next few days. I'll let them inspect them and hone/bore as needed.
I know the kits come in different sizes. If I need to bore I'm thinking as little as possible right? less oversize equals more reliability right?
Thanks for the links and prices! I thought the kits were rather inexpensive so I was unsure of the WSM name brand. I found kits at Atlantic jet sports for ~250.00. Anybody have and experience/comments about AJS?

Bore as little as possible, correct. To properly bore the cyls. you should have the pistons with them, so the machine shop can cut each cyl. to that perspective piston. I've dealt with Atlantic on a number of occassions. They are good to deal with, good customers service, prices quite fair, it's just they take a little time and a little pricey to ship. Overall good place.
