Teeth currently are 41/16 and I believe I can go to 47 teeth on the rear sprocket and I believe that would give me more torque at the rear end. Maybe I can search or custom order a new rear axle and find the hub that works with '520 chain sprockets' and have a hub welded up so that the rear sprocket will be in line with the front sprocket. I don't know if the Crossfire's axles are custom made per length etc. but there are a ton of axles out there. Other than buying a new Ninja sprocket and the thinner 'Crossfire' sprocket and taking that to a machine shop and having it put together and HUBCENTRIC is a cool word. Hubcentric is a good thing since most automotive wheels use the same theory to keep the load of the automobile OFF the lug nuts. Thanks for that advice and if you run into an axle supplier for the one that matches the measurements (minus the hub) of the Tomberlin Crossfire150, please let me know. Thanks. Scott
