The new pipes on my '07 speedie, are practically straight, and I have noticed a loss of power, not a lot but some. It sounds amazing,but I am ordering a baffle to put in the pipe that will hopefully help a bit.
I did take the bike in to make sure it was jetted correctly, it backfires like crazy, especially on deceleration, and when the engine is cool. The shop suggested, some back pressure in the pipes should help the backfiring. Any thoughts?
