Hey Forum, I`m new here. I have now fit the Cycle x tri Y Race Slip On 2,5 "for my CB 750 K2 Cafe Cruiser Scrambler Project. But it doesn't work very well....no power in the lower speed Range. I have the original Keihin carburetor with 135 Main jets and Open Filter ! Also a scheibel exhaust manifold. I hang The carb needle one Point higher and With DB Eater and 140 main and 45# slow jets it works much better in the lower Speed range. But now not in the higher Speed range. What else is needed to modifie ? Another slow and/or mean jets ? Who has experience with this muffler ?
Thank you very much
