I did say minimal gains. When I got the bike I went mod crazy. Did the full exhaust, air filter, carb tuning, 22 cent mod, snorkel removal, as well as chain and sprockets. So wherever the power came from I can't say. But even with all that done only picked up in the ballpark of maybe 5 horse... Guessing high there as well. The only different in the powerbomb headed between stock was the actual powerbomb bubble. Pipe diameter was to the eye identical.
