I've been lurking for awhile now and figured I may as well become an active participant here. I bought a 48cc kit from revolution cycles (no instructions) about 3 weeks ago, then found this site while looking for instructions on how to put it all together. Found a lot of helpful info here. Put the engine on an old Murray cruiser and have been motoring for the last two weeks. Still trying to work out some bugs, but it sure is nice to be in the wind!
