I recently removed my factory baffles from my screaming eagle mufflers. I then installed splitters/lollipops to regain some torque. I put the lollipops in perpendicular to the muffler. I also had the Keihin CV carb rebuilt and the tank flushed 3 times due to trash in the tank. This bike sat mostly ( 1600miles in last 6 yrs. prior to my getting it last March. I have put 5k on it this past year. I was told that my cam sensor was fried and got a new ign. system installed without a cam sensor. The bike runs great since this work was done and I know the shop that did the work and they are good tech's. I now get a spit/sputter condition at hwy speeds only ( 55-75 ) when I am putting a demand on the engine. It begins with a noticable feeling of just hitting a strong headwind ( engine running same but a noticable slowing of bike ) then the spit/sputter begins to the point of stalling. If I slow down it will clear up. Doesn't seem to have any bearing on level of gas in tank. Could the lollipops be causing the exhaust pulses to back up to the heads and create a intake/exhaust issue. Any help would be appreciated. Thanks folks.
