I originally ran stock, then wanted more power. I unhooked the O2 sensors, did exhaust, Vic performance filter and Stg 1 flash and then stopped. What I noticed was an unacceptable way the bike ran. It started backfiring and MPG noticeably dropped. I picked up Llyodz air filter to offset the issues I was having. They remained. I was recently "awarded" a significant speeding ticket that caused me to look evaluate what I was doing. I hooked up the O2 sensors and reinstalled the air strip around the filter (yes, it needed to be modified) so I'm as close to stock as I'll get.
The results, backfiring has all but been eliminated and my MPG is closer to the 50 others are reporting. My loss of power? I cannot even notice it, if it IS indeed lost. I've kicked around the idea of a fuel controller and cams but right now, for me, it seems like a waste. I want a solid bike with good to great power for any ride, long or short, I want to take. That is exactly what I have.
Oh, and to that heat thing. I only notice a buildup of heat with my closeouts on.
D&D pipes, PCV, Llyodz performance filter w/strip in place, Llyod's timing wheel (set +4) and various other visual do dads. :cool:
