So i finally was able to get on the road last friday and get the ol girl warmed up enough to do a plug check to see if i was to lean after installing a 4 into 1 vance and hines pipe that a buddy just happen to have and gave me, sweet $300 saved. Anywho, pulled the plugs and all of them are looking perfect. A deep tan color on the electrode insulator and not to much soot on the inside side wall at least that's what I think is almost perfect. For some reason it tends to feel like I am running a little lean though, a little back fire every once and a while and a little chug every so often. Is it a good idea to go ahead and richen it up a little or should I just leave it alone?
