Thanks for the comment Kev, interesting your bike did not show the contact in the hub that mine did, I'll be changing the bearing soon.
Just some notes about the mod, because of the damage to the bearing boss I polished up the scarred aluminium with "wet & dry" so it did'nt cut up the plastic bush & the thicker you make the bush the better to give it some strength.
A couple of "perceptions" after doing this were the bike felt to have less driveline vibration and the throttle response felt sharper, more instant, perhaps because the torque is no longer twisting the hub but pulling directly in line now.
