    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I must admit I take a lot of chances on parts from fleabay. My philosophy has always been that most people are decent and honest and are not trying to get you.:D

That said, I purchased a flywheel/starter clutch/rotor/magneto whatever the description dujour, wanting to make life easier should I need to repair my charging system in the years to come, I bought a rotor from an 82 GS850 to go on my 79 GS850.
I also bought a stator to go along with the rotor from a 2002 GS550.
18 pole, windings are like new, etc. etc.

Anyway, I just got around to pulling the rotor from the bike, man is that fun!!!, and was ready to prep and install the 'new' rotor.
I always do a surface check before installing any part to check for deformity and I found the inner race to be scored.:(
The scoring is not a run some light emery paper or steel wool and remove type, you can feel the grooves in the metal surface.:mad:

My crankshaft end is pristine, not a score, mark, or groove to be found.

Would you all take a chance and install after a light clean up?
Or would you mark this up to being taken and start to find another?
 
The tapered surface inside the "new" rotor is scored? or the magnet area? Unless it spun on crank during some accident, I can't see how this would happen. How does the exterior of this rotor look?
 
The exterior looks fine.
The only way I can figure this happened is if they ran it not tightened.

The grooves are all the way around from front to back.
 
Sorry, the tapered surface.
The magnets are fine as are all the rest of the surfaces.
 
Got pics? :D

It would probably be OK, unless it's some sort of heinous mess. Maybe.



Also, I've got a couple of these rotors around and I live on the NW side of Indy. You're welcome to one of them, or maybe we can get together and look at the rotor you have.

I hate to suggest this but.... I remember using a brake cylinder hone on a inside taper back in the dark ages, but I can't recall why.
 
Yeah, that thought had run through my head.

My concern is the taper is pretty close tolerance anyway, if I remove the crud it may be way out of tolerance.
I have looked and do not see any spec on tolerances for that, my bet is that they consider the rotor a 'throw away' part.

I found another :pray: for 25$ shipped and I bought it.
I don't need the headache if there would be some spin on the end of the crankshaft.:hand:
