I need jetting help. I own a "94 300EX and nedd help with the jetting. I have an 11-to-1 comp. wiseco, a supertrapp full exhaust with 7 or 8 disc, no air box lid, a K&N filter with outerwear, and currently have a 130 main jet. I would like to put the airbox lid back on with a few mods. Right now it stutters on top end and is fine throughout the rest of the RPM range. What size should i run. I tried a 140 but it only helped a little and when i put the airbox lid on it ran super rich.
