Hey everyone. I have a friend that we recently got into the sport this year and he has a 98 srx 700 and it could use some new rings as the compression is a little lower than I'd like to see. He hasn't ridden his sled yet (no snow yet) so he is thinking cheap and wondering if he can just change the rings without buying new pistons, wrist pins, cage bearings, etc as long as these things are in good shape. We haven't opened the top end yet so I don't know what pistons are in it, but is it normally okay to buy say parts unlimited rings and put on whatever pistons are in the motor? Thanks for any pointers!
