  1. alright guys. I picked up my 1st shee about 3 weeks ago. Its been a blast to ride. Motor is all stock except for fmf fattys and 2into1 carb. I advanced the timing 4 degrees yesterday and liked the bottom end response. It was slight but definately noticable. I am thinking about the chariot racing cool head and going with 17cc domes. I live at 5500' elevation. the compression is at 100psi now and I think that I should be at 150-160psi with 17cc domes. You guys know how big of a difference this will make on the bottom end? I only ride trails. My 2003 cr250 is pushing 170psi and lugs like a 4 stroke....it helps that it has a power valve, but was wondering how the banshee would respond to a significant bump in compressoon. Thanks DUDES! :headbang:

    Im at 5000 ft and run 17s on my beater and im only pushing 130 on each cyl, 150-160 sounds kinda high :confused:
