So my blaster has the TORS delete with a KEININ Pwk carburetor, it was running good with the stock exhaust however it had a big exaust manifold leak. So I replaced it with a Fmf fatty gold series pipe and fmf muffler and it won't idle and it bogs and is really sporadic and jerky at low rpms, like it fouls the plug immediately pretty much. The carburetor has a 168 main jet with needle at middle clip, and a 42 pilot jet. Oh and it smokes excessively at low rpms, mixed 45:1 with yamalube and 94 gas.
