Just put in the JD Jet kit, Red needle 5th clip,160 main, 42 pilot, Zip tye 2 turns out, Air box mod, twin air filter w/ backfire screen removed, Stock muffler insert drilled 13/16 in at end. Bike accelerates excelent, no bog at all, no flat spots, very impressive compared to stock... only complaint is on long deceleration it pops 1 to 3 times out the tail pipe. (Did not do this with the stock 130 jet, 40 pilot and stock needle)
If it was not doing this, I would say the jetting is perfect the way it starts, runs and accelerates.
What can I do or try to clean this up? Any advice appreciated.
