Over the weekend I performed surgery on the airbox and the stock exhaust cans. Holly poop that plastic in the airbox is thick, about a ¼ inch. I went through 6 blades getting through that crap! It turned out very nice, flapper be gone. I just cut out around the lip and smoothed everything out. I also drilled (7) 1/2 inch holes in each exhaust can baffle plate – it sounds great. I also put in the BMC air filter. I then had my dealer's service department use the Yosh Fuel Management box to reset the fuel mapping. He suggested +5, +5, and +10 as a good starting point. I hope to dyno the bike tonight. Overall, the bike doesn't seem to run any faster or slower. The bike at an idle sounds about the same, maybe just a little more rumble sound. At half to full throttle it sounds fantastic, not real loud but you know it’s alive. I’ll report back once I get a dyno run.
