An 81 Sturgis. Has anyone ever tried to rotate a motor by using a socket and an impact tool?
It's a dry belt drive with no oil to worry about.
The bike has some starting issues and would like to not grind down the battery. Don't know
what would happen if it started. Whiplash from an electric cord????

I believe you would remove the nut.
just use the starter.
many worry about impact knocking the magnets off the stator.

The bike has a kicker but it's a problem troubleshooting while kicking.Plus it's almost for sure the starter
would overheat and could fry the solenoid..The nut is torqued very high. I needed an extension and some math to tighten the nut last time.

I didn't intend to use the impact tool as an impact. The motor turns freely but the rotation is in
the loose direction. There is the locking washer but it could fail.
I can glue the magnets back on if they fall off but I see your point. Keep thinking of the starter method used on drag bikes
to get them going. A handy thingy. If I do try this I'll post the results.

You might be better off making a set of rollers like they use on some race bikes.

Roller starters still Suck...Dragbikes are started off the crank...But, the socket is securely bolted to the Sprocket.. don't usually leave room for a Primary cover.. I guess I simply do Not understand the Kicker don't work for troubleshooting!! Always worked for me..What can possibly be gained by spinning the engine vs rolling it over slowly???

‘customers bikes when an issue is the thing - I press the starter button and kick it at the same time - this i have been doing since the 70s - back - when everyone had to have a stroker and compression. It was the only real way to start one

With the method you suggest, you are lilely to do more harm than good.

Diagnose the problem the old school way starting with the basics. This isn't a bike with a canbus system and compression releases etc.
