P.S. I use a hatori pipe, which when i looked inside it was very clean. The carbon deposits seemed to only stick to the header. I'm also hoping for any better solution. Is it the fuel, a motor problem, or header problem(ie. to narrow) ??

Hey riot3d is your header the newer style NMP header from Central hobbies or the older style one that was out 3-4 years ago which has a sleeker/narrower front portion ??
