We've found lowering the wheelie bar unloads the tyre when the bars stop, It's uses a radial tyre. It's a fine line between wheelstanding and spinning,you can just see it unloading around 40 seconds in. We would be better off with the Caltrac mono bar than the axle mount wheelie bars fitted now but have the tank in the stock position.

thanks Bigdad for putting up the link
