Who is Windy and how do you buy these clamps from him? Thanks!

Thinking this might be a mod to tackle this winter. I've definately felt some whallow in the Commando on some of my favorite corners, thinking this mod could help with that.


If you have the bike on its center stand, grab the rear wheel and push it left and right. If you can see your drive chain going loose and then tighter, then there is slop in the swingarm. If the drive chain does not show movement then any slop is probably in the isolastics. However, it has been pointed out in the past that even a tight spindle will eventually get loose and the clamps will be preventative.

Or, I seem to remember one of the racers had welded in a steel plate across the rear section and drilled it to reduce some weight.

This is a great thread about cradles that includes a picture of Dave Winship's reenforced spindle. The whole story and pictures of Dave's bike are on the INOA site on Yahoo in the files section.

You probably want to go into town, and find a up to date Jap Bike store,
With a full spares department, a clean workshop, and kean young mechanics.
And ask them if theres a Grumpy Old Bloke out in the Hills, who knows how to fix Real Motorcycles.

Indeed as all we got is our short time here, some of us want to spend as much of it in gleeful cycle fun as we can get away with and indeed an untamed Commando will do a limping short leg broken neck waddle right off the path just went its getting to be best fun there is. Actually if ya try to ride through that phase Cdo becomes a flopping fish right off the deck. I am besides myself to know what its like on one that just never can be made to get upset. It will make you crazy, beware!

Had to use a tap to catch in the end of the spindle as it was in the wrong way around, no thread to pick up on, filled with grease as well and dry unlubricated parts on the spindle.
Other wise all in good shape and swingarm is not twisted and sits 'true' on a level bench.
