Ive seen jetting issues with clones and knock offs first person even after a friend took it to a "shop" still had issues (Keihin clone carb on banshee). Im swapping the carb out for a genuine mikuni with K&N clamp on foam filter and trying to get as much hp possible with a nice exhaust. Then again these hawks arent meant to handle a race quality beating but I wanna see it through i get the most outta mine.

Good idea. The head pipe is the worst I've ever seen for exhaust gas flow. At the minimum, change the head pipe, and you will be even happier if you use a copper o-ring gasket between head and pipe. I like the VM 26 Mikuni for this engine. Very easy to tune, and parts are easy to get. There are pages of info on that carb, if you hunt for them, on this forum. I would much rather have a more open muffler/spark arrester than a tachometer on an off road bike. You don't have time to be looking at a tach when you are going through the boonies. Your ear will quickly learn where you are at, rpm wise. The pilot jet, and the throttle cutaway control low end, up to 1/3-1/2 throttle. Ideally, when you have the right main jet in the carb, the needle will be in the middle slot. If necessary, raising the needle a notch richens the mixture, lowering the needle weakens it at up to 3/4 throttle. Hope this helps you.
