This thing rips. Never new the power of the circuit pipe. My race bike straight pipe hits at mid-range and keeps punching into high rpms, but this snakey pipe hits right out of the gate. Mellows out on the top end.
Had to upjet the 17.5 polini carb from a 68 (that worked great on my Lazer with a ktm 50 pipe) to a 74.
Changed the gearing from a 10-42 to an 11-38 and it still blasts. Gonna have to GPS some speed runs. Felt like mid 40's with the 10-42.
Pretty sure I have the stock springs in the clutch, I forget. Probably gonna put in some blues.
First time I hit a good bump brown water squirted out of the boots and it bottomed out. Felt like hitting a curb with a flat tire.
Pulled em apart, dumped out a bunch of water, cleaned them, and they still bottom out, with no way of adding bushings to cushion it.
Probably swap out my Lazer fork legs, but then I need to put sealed bearings in the hub...
