Oh yea, if I could find atleast a late 80s or newer 80cc 2 stroke chassis with no engine, I'd gladly build up one of these engines for that! I've wanted to build one of those since the late 80s when I saw my first one, but have never had enough parts to do it at the same time. I had a 92 kx80 chassis at once (strangely enough I bought it 4th hand, but it had been one I raced against at one time), but got rid of it after letting sitting around for a while and making no progress. I'd much rather have had a big wheel chassis anyway, but otherwise would prefer a cr80 chassis, might as well keep it all honda! Idealy I'd snag a cr85 expert sans engine for the project, but that would be spendy.
