Seems kinda strange. The air temps aren't that high yet. My bike just runs the fans alot off-road this year. Just did an oil change and all is good. No coolant loss either. Oil temps yesterday got to 242. Climbing up a canyon in the dirt averaging about 30 mph. I have never seen anything higher than 226. I was also down on HP at my last dyno session. Could have been the different airbox, but it's the same thing that SD's are seeing 5-10 hp gains. I think I'll do a leak down/compression test. What #'s are you all getting? I think I read 195+-. Break my heart if I have to pull the heads off .
