A buddy rides a 2007 Boondockers M7 turbo @ 9psi on C-14. Last ride he noticed a bog going to full power, that started at 7500rpm up to 7800rpm. Sled runs fine from idle up through midrange. He pulled the plugs and found one cylinder a chocolate brown and the other not white but had hardly any color at all. Obviously the one side is lean but why??? He did find a tear in the belows of one of the exhaust valves, but this was on the cylinder that was running chocolate brown. Any ideas? Thanks in advance. Sean
