Welcome dude! No need to buy a jet kit, waste of money. Just get a few jets up from stock. (And wouldn't it be jetted for the pipe and filter already though?) Quick and easy things to do right off the bat; the pen spring accel. pump mod, and swap on a direct shifter.

cool thanks i assume the how 2 are in the stickies, also u would think they did jett it but they did not and it killed the rings i just did the ,20 over piston i want to make sure it doesnt happen again.

like deadlast said just get some jets from a dealer. stock is a 145 main so maybe get like 147,150,152, and maybe get a 45 pilot jet for the low end.
