ok heres the deal, my bike was rebuilt and he pistons were put in backwards, long story. The cylinders were damaged and are being sent out to be bored. But hey, why not port it at the same time right? I talked to robert byrnes from bd racing and he's doing an aggressive dune port and the boring for me with a matching set of pro lites. i am also putting on a trinity 2 into 1. A lot of you guys have told me to go against this, but i want the reliablity. How much of a power gain should i expect to see from these mods? should i just say f it and stay with the two carbs? check my sig, i run straight 110 and i am installing 17cc domes instead of 19's. I run straight 110 octane. Anybody guess on ballpark hp from my sig? all the info you guys can give is great, appreciate it.
