I run 32:1 Klotz Supertechniplate. Great oil as many of the guys will tell you, even smells great. When I'm done racing people and they smell my exhaust, they always ask if I run racing fuel. As far as the cold go's, need to probably go up a jet size or two, probably came w/200's stock, may want to 220 to start to be on the safe side and see how shee runs. Info is assuming shee is completely stock. Oh, and welcome to the HQ.
