While we're on the topic of rings..how long should it take to break in a ring. I installed one a little while back in my webra silverline 40 and ran a few tanks of fuel through it. It starts right away and runs good from idle to full throttle but still not much compression. What it the proper procedure to break in a ring? I ran a fuel through it, idle, half throttle, full, and back to idle again:let it cool down all the way and did the procedure all overagain a few times. I'm running 5% nitro but not sure on the oil content. There's lots of oil residue in the exhaust. Any Ideas. thanx
