Well, it seems everytime one of my buddies comes up with a crazy, hair brain idea they end up coming to me. I must have a rep as a nut job to be targeted like this. Well, yeah, done some odd things myself. I'm gonna need all the advise I can get on this one. So here's the deal. Buddy used to hill climb Yammy Y2's that he stretched out. He's getting back into it and he's shooting to do the 600cc 2 stroke class. Sounds simple right? Buy a 600cc 2 stroke and stretch it. Simple. Nope. Not this guy. He's found a sled engine, a Rotax 570 that pushes 105 hp. He's got a couple of frames that it will fit into nicely. The deal is.....the drive system is the dual centifigul clutch/pulley set up from the sled. Get the picture? So.... the drafting of a plan is on the board to find a way to go to a single clutch/belt drive to more than likely a jackshaft to convert to chain drive to the rear wheel. In my mind....too much HP would be lost through a jackshaft setup. Not to mention the issues of tenisoning the belt from clutch to jackshaft. My thought is to use a single notched belt from the centrifigul clutch to a notched hub pulley on the rear wheel. Tension adjustment would be simpler and less power loss. Now I might mention the last time I messed with centifigul clutches was when I built my first mini bike. I see this working but it's going to take some creative engineering to pull it off. But like it has been said here before......Nothing is impossible. Anybody care to throw some ideas out this way? Mike
