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.

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.

Secondary Gear Tips Party

I also just did the same fix on an 82 GS1100 GL............thanks to the info from this site....and the wisdom from 49er and Zooks....Snow has melted enough now to get the bike out of the shop....200 KLMs on it...... so far ... so good !!
 
What were the underlying causes of the gear snapping for everyone? Or is it just something that just wears out with the age of the bike and all the torque put on that specific place?
 
IMO the failure is caused by a defect in the machining or hardening process. FWIW, I found a broken shaft on my '82 1100G over the weekend when I removed the flange from the output shaft.

Hey, if I bought the upper and lower secondary gears off another bike, the only thing I would need to replace when I put them in mine is the o-rings right?
 
Yes, BUT be completely AWARE of exactly WHICH bike you are getting them from. The 850 gears wont work. They are too small/short whatever you want to call it. it must be off an 1100G, 1100GL or 1100GK...There are no visible differences in the gear that the shaft bolts to, but the drive gear IS visibly different. If the outer plate (the part you see when you take the shifter cover off, before you take the gear out) looks different than yours, its off an 850...

I have a spare set from a 1000GL, part numbers are the same as the 1100GK. Have the O-rings too. Let me know if you want them.

Ed, if he doesnt want em, My roomate just might for his GK. We bought a set off of Joe and they were for an 850, he didnt know they were different and neither did we so no ones fault there, but I havent been able to locate him a set on ebay that im sure are decent, and a new set (have to be purchased in a set apparently, otherwise i have a good driven gear) are 200+ bucks...

Josh,
The gears are yours if you want them. I deleted my message because I think it came across as hawking my old parts. I don't think sueadhead needs the gears, just some new O-rings.

You have a PM Sir :)
 
You don't 'have' to buy them in pairs Josh. You can 'lap' them together using grinding paste, the same way they do crown wheels & pinions in diffs. It's a bit of stuffing about but it can be done.

They're generally kept in pairs in case they have 'meshed' together over time. Putting two 'new' gears together would cause huge amounts of whining and maybe chip teeth, wear unevenly etc.
 
Yeah, I bought them off a gs1000. I looked up the parts numbers online and they match for the 1100gk. I was just checking to see if the o-rings were the only things that really needed to be replaced when you put the different gears in.

not sure if this might have been said earlier... but it is important to get the backlash (shims) right, otherwise you risk another failure down the line
