Dduelin, thanks however I will check tomorrow as the last I heard they were NZ$ 186, which translates to about US$90 and that is considrably more than than the USA price. If that is the case I will have to check the cost of shipping from the US.The 1300 cush rubbers should be a tight fit with the wheel and spline hub - it's a job to remove or press the driven hub down into the wheel. New ones are relatively inexpensive at $20 but they last forever. Part number is 06410-MCS-G00. It's a nice motorcycle, ditch the inner tube pieces and make it right.
You are right, I'll ditch the inner tube spacers.
