With a 68cc chamber, you may need a dished piston, but with a 72cc chamber, a flat top may be in order. Once you have some possibilites, start combining them with cam specs in the DCR program mentioned in a previous post. You should not have a DCR above 8.5 for pump gas, 8.25-8.5 you should figure on running 92 octane. The closer to 8:1--89 octane, under 8:1 you are more likely to be able to run 87 octane. Now these are just ballpark figures, and all engines are different. What might work for one may not work for another. When you think you have a combination that might work for you, post it and we can give you some feedback.
