  • 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.

What is this?

Hap,

I can't think of anywhere in the top end for a bearing such as that, unless it goes in the con-rod for the wristpin. My 850 has no such bearings. I do remember such a bearing when I rebuilt my TS125 dirt bike for the con-rod. I looked on bike bandit and couldn't find anything that size. I did notice that the RN in front of the size may siginify where it is located. In all the 1100 diagrams, the crank end of the con-rods all had bearings that began with RN. Maybe it doesn't actually fit an 1100.

I believe that this is the bearing that goes between the crankshaft and the gear on the starter clutch.

There were originally two bearings about half as wide installed. When I replaced the starter clutch and rotor on my GK, the parts fiche listed the wide bearing as superceding the two narrow ones.

I have had that bearing in my motor for about four years without any problems.

The number Robinjo listed is the same as listed on Bike Bandit for the GK. I am beginning to think that the rotating assembly, starter, starter clutch, clutch and ignition rotor are the same whether shafted or chained.
 
The muffler bearing is much larger and comes with different Left and Right side part numbers!

Sheeesh!
 
It is the starter clutch bearing, 2 are listed on bikebandit. Probably a common part for a few of the motors as I looked up a GS1100ET.
 
2 questions:
WHY would anyone buy a simple rollerbearing for 10 bucks off ebay? :-k
WHAT the h##l does "NOS" stand for? I see it all over parts on ebay. :?
 
The later roller muffler bearing replaced the framis bushing that was tested on some pre-production types.

Clone, NOS= New Old Stock (or $hit) It's the stuff that has been (so they say... :roll: ) 'lovingly preserved through the years' for later generations. Which is marketing for 'Thank God we can unload this crap and recoup some of our investment.'
 
I'm familiar with the nitrous oxide=NOS one, but not the other. Thanks
 
NOS ain't always bad, some of those parts have saved my butt when they are no longer available anywhere but junk yards. You just have to make sure you get a good look at what your buying before you commit.
