I have the Morton infernos with PCV and stock air filter. I have noticed some yellowing at ports. I have read that is do to running to lean. Without having it on a dyno how do I fix it? I hadd doug at Morton's load my map. He will be getting a call as well but I figured you are the R&D guys so PLEASE hook a brother up? and I have a handicap as well not to familiar with te PCV but I did have it hooked up to the lab top and I understand kinda what I am looking at. Thanks in advance oh yeah what would be the best way to cut down my chrome pipes? one is scraping and being a retired knee dragger I still like my corners but damn these pipes wont let me turn right for shit. Please help!
