I have been trying to chase down the issue to why my blaster runs like crap. I have the FMF fatty header and the powercore silence, vforce 4 reeds, it has a 270 main, 32.5 pilot. I have tried replacing the reeds with another pair to see if it would do anything. With the air screw turned in 1.5 out, the high end will hang out until I blip the throttle again, the low end isn't there, but runs okay. the bottom end runs great with about 3 turns out, but I'm afraid of running too lean. Another thing, if I'm in 5th or 6th and let off the gas, it wants to die out and wont gain in rpms. Im somewhat new to the carb game. is somebody could help that would be amazing. thank you.
