For anyone who cares, I have been running this 925 for 3 seasons on my 13 M800. I now have just over 4000 miles on this sled and it hasn't skipped a beat since I got it tuned correctly. It has been ridden at high alt. and low alt. I have been changing domes for different elevations, I have had to adjust the fuel for the different domes but not very much. This year I got lazy and just left the 14:1 domes in for low alt. and added 110 octane to the tank to make up for the compression, with this setup it really performed excellent at low alt. I really can't complain about this engine package at all, it has just been awesome. Thanks for reading TB
