This is a question for any racers out there. How do you break in your piston rings when you're in a race season? I put a new set in a freshly honed set of barrels did a 10 minute run in session (as thats all the time I had) and by the end of the days races the ring gap was about 3mm on the top ring (and alot of smoke from the exhaust as you'd expect). I've now been thru this twice with the same result. Obviouslyy I'm not bedding in the rings properly but I haven't got the time to do 500 miles (it's also not road legal).
How do you guys do it?
