look at what's in there and buy a handful above and below that, then trial and error till it runs the best. A few full throttle runs and plug checks should do it. If it speeds up when you back off at full throttle you're to lean, if it doesn't scream like a chain saw on methamphetamine at full throttle you're too rich......


Peice o cake son...
