reed and rotary header


New member
What does difference mak with a long header,short header,tapered header fat skinny etc.i run a cre 6 pipe on a 117 cc rotary.i have the buller tapered header.would i benefit running bullers fat 100cc header with the cre 6 or the tapered.or maybe rlv makes a good header.i also run 17/8 flex.thanks brad hayden
From what i've heard the short taper enhances lowend., however if someone put one on your engine and changed it to the other one, and you don't know which is which, I doubt you would be able to tell a difference.. you may see something on the stopwatch or dyno..
