Howdo..I refitted the rear wheel and done the belt tension but can't for the life of me get the wheel alignment right..when I spin the back wheel backwards the belt walks to the inside of the pulley and spun forward it moves to a few mm to the outside of pulley I've done the piece of wire centred in the spindle hole and it's the same both sides the dyna has a small hole about 3 inches in front of the spinde adjuster..its doing my head in..any tips/suggestions?? I've done chain driven bikes for yrs but this has me ???obviously the wheel is pulled to the right slightly but the measurements add up..if it had normal chain type adjusters Id measure the amount of thread either side but this has allen bolts that screw into move the spindle adjuster..doing my head in..
