Depending on your elevation, I would sugest going to a 152.5 or 155 with the K&N and the WB Slip-on. Better to be rich than lean.

yeah the plug looks a little lighter than i want so a 152.5 might work well. Do you think it would need any needle adjustment?

You shouldn't need to adjust the needle for just the pipe and filter, but it wouldn't hurt to see if it works better for you. Like I've stated before, it's better to be rich than lean. Good luck! You also can change the needle without removing the carb from the motor, just be really careful when pulling out the power valve and putting it back in, make sure it's all even. After you have the cap back on and tightened, use your finger to lift the slide, be sure there is resistance there, like blowing up a baloon (but not really stiff).
