I have a new Zeda80 Triple 40 that one of the piston rings it came with broke. I've already bought 2 sets of rings advertized as for the 40mm piston. They were both the wrong size and I had to send them back. What is the correct piston ring size for the stock piston in this engine? Can somone plz provide some links? Thanks!

I think that engine doesn’t have a 40mm piston it has a 40mm stroke. You really should measure the bore for a reality check.

Ok. I had to take it to a small engine repair shop because originally I thought I had dropped one of the piston clips into the case. Since I had never completely pulled one of these engines apart, I Just paid a shop to do it. But when they put the top end back on one of the rings broke and been looking for the right size since. Thanks for the info I'll buy them right away. Cant wait to get this motor on my bike. To Larry: I sure will check it. Thanks to both of you!
