We have had good and bad luck with RA seals. Got a batch not to long ago that warped for no reason and we warrantied the engines with stock seals. Then we have one of our shop cars running over 20psi on RA seals with no problems. We recommend a lot longer break in period if using RA seals.

Nice could you also do a compression check? Are you running premix? And what a/f ratio do you have under boost? Oh yea, do you have stock springs?

RA springs, havent done a compression check, but dont have any compression related problems. sort of running premix....search my name and MOP, and you'll find my thread on my 2-stroke MOP mod. a/f under boost is about 11.

Over 10k mi, 17psi of boost, RA springs...good long break in. 1500mi or so. A:F = 11.4
