First: This is an '09 RKC with the factory SE stage II 103 BB kit including the SE-255 cam, flat tops, and SEPST. Recently, added heads from a new 2012 103 with ACR's to cure the starting problems. 2000 miles since the head swap. Just had it dyno tuned to improve on my many smart tunes. The bike runs great. Really great. 105tq and 85hp. The tuner however says that he also did a hot compression test and said it looked a little high at 220 psi front and about the same for rear. I am used to seeing 180 on Evo's as high. But are the 103's with the SE-255's running that high? I don't hear any pinging. Well I did a little on a really hot day last summer coming out of Canon City, Colorado. I was climbing a steep grade, two up and packed, on a 98 degree day. But that's about the only time. Anybody else have that kind of compression?
