Thanks Hoppy, yes was going to go with a max torgue clutch and chain. the tires are 24" bike tires, i was thinking 14" trailer tires but need to install some 4 lug hubs, maybe go kart. as for the tank will need to get the petcock, line and filter. the engine itself has a fuel shut off on it. I am quessing i just need to remove the tank from the engine and run a line from the harley tank, or just removing the line from the tank and run a longer one to the harley tank. just think the back wheels look odd on it, but they are the original bike wheels. as for the sprocket on the axle it looks to be pretty big, havent counted the teeth, just quessing maybe 6" in diameter. thinking a 12 tooth clutch and a big rear sprocket should be good. thanks for the suggetions.
