Monster Moto front forks with 10" rims and 16" tire front.   Rear 8" rim on 15" Kenda.  He hubs from brakes to drive to sprocket.   
625 Vegas carts ungoverned. 34 Clements black billet carb.  1 gallon Spun aluminum gas tank.  Kick stand.   Megaflow Jr race
fuel pump. Billet thumb throttle.   Vintage bmx handle bars. Turbo 1" bully. 69 rear, 18 front.
With a basic big block plate these fit exactly.  You guys
should do a build like this.   The only Fab part I had made
was exhaust.   Your Nitro 50 fits this in with room to fit.
