Tri Z porting and Piston questions-

[200x Basket]

let me get this straight.

you are sending a cylinder off to get ported but you still run the factory pipe, filter, etc?

i like a powerful engine but you need to get the stuff in order. a ported cylinder on all stock parts will give little to no benifit. a updated carb, pipe, K&N, and a fresh bore will give a better benifit and more reliability.

Ah I see your point, and have already order DG, Aktive reed cage and filter for it
