Hey guys,
I have posted in like forever, but I have a question that I sorta know, but am not to defenite on. Currently I am running RC 310's on a built b18c1 running 10psi and I got a good deal on some 440s but the only thing I have is a Field VTEC controller. I know I'm going to have to lean it out, but how much do I need to adjust the fuel and at what RPM's? I searched the archives with no luck, so any help is appreciated. Thanks

Aaron
