Is anyone running an hmf slip on with k&n filter? If so what jetting and air box lid mods are you running. I just put mine on with a 180 main, 2 1/2 turns on fuel screw, and cut lid (looks like hrc lid but a little less cut off) and it just doesn't seem to be running right. I started off with two 2" holes cut and it was cutting out so i cut some more off the lid and it runs better. But i bought a new plug to check the mixture and i rode it for 10 minutes and then checked it and it still looked brand new. It seems a little sluggish like it's rich but according to the plug it's not. Any suggestions?

I would try posting this question in the HMF engineering section and see if one of those guys can give you some help.

Have you done any other mods? I would guess more around a 155 for just a slip on exhuast.
