I am still thinking of increasing the Sprocket to 46-48 teeth as I saw Wild-Bills youtube video of his ktm50 and he recommended that. I have never raced and was not planning too but I wouldn't mind giving it a go. I saw a post the next race in Apple Valley is Oct 22nd. I would go but the problem is I'm not sure I would finish mounting my engine by then. Everything is ready I just need a welder to create mounts just like Bill's. I already bought all the parts and the mounts Bill uses but I do not know how to weld I'm searching for someone in the inland empire.
