650 primary cover

Norvil used to sell a kit that spaced off the outer cover. The main component being a large alloy washer that sat on the footrest shaft between the cases. This arrangement also allowed air to pass through the cases and help cool the moving chunks. A large steel washer might be just as good. What you need to watch out for is enough thread being left to hold the footrest in place. Plus a slight bend in the brake lever to stop it from fouling the outer case.

In answer to the first part of your question - yes there is a BIG difference between Dynamo and Alternator outer covers! You can't use an alternator in a dynamo-type cover as the front dome is too small. I'm guessing that this is the wrong question though as you wouldn't be using a dynamo anywhere near a 650SS!

I got a hemmings belt drive kit for our 650SS but the alternator stator is hitting the outer cover, it would require spacing off considerably if it was to clear.
