On the popping, are those pipes baffled? If not, you will get popping when letting off the throttle. My Martin Brother Madussa's pop Fire out when I let off. Carb has been set twice and both mechanic's say the same thing. Nonbaffle short pipes =poping!Every now and then when I get on the throttle it pops/misses and then takes off strong. Got some backfires when coming off the throttle as well.
More preventative than anything. I would assume a tune would be just the carb, correct?
