Lockman,
Which carb jet did you go with for your setup? I have tried both that came with the kit, and both seem to perform questionably. I have the performance exhaust, K&N, and the carb jet, but I'm still getting HORRIBLE results. Dont get me wrong here, I'm not blaming the parts, but rather my ignorance
I have heard of guys drilling some holes in their airbox but I dont know much about it. Where, and what size holes do you use? I have been very dissapointed in my performance upgrades, but some of this may be due to the exhaust leak, and some may just be getting the air/fuel ratio right.
