Topic: further proof that 550's and o-ring chains do not mix! (pic)

[jonda500]

I had already done 200miles with an o-ring chain fitted when Dave set me straight about this (big thankyou to Dave500), I thought while I had the cover off to fix an oil leak I should take a pic of the damage that running a DID brand o-ring chain did do did do! As well as the damage to the crankcase and seal near the sprocket shaft, note at the very top of the pic where it took a bite and bottom left where it was also rubbing! When turning the wheel by hand this chain DID NOT rub at all- but clearly at highway speeds it definately does- I had maybe a quarter of a teaspoon of engine crankcase aluminium dust in the bottom of the cover!
  I now have a brand new oring chain and a 200mile old one that I can't use on my bikes - anyone want 'em?

The reason it dont hit when turning by hand is that the sprocket has a small amount of "Float" on the shaft and so moves under load, also there is a small amount of play sideways of the chain on the sprocket.

If you turn it and push the front of the sprocket inwards and the chain in you will see it

I reckon we could form a club of riders who have fallen into the trap of fitting o-ring chains to 550s.

I'm certain there would be many members.

if you ride with a bunch of guys with all sorts of bikes one might use a 530 chain? you might be able to sell or swap for beer the o ring chains?
