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.

    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.

Personally, I want to see the 1987 GS1000. :-\\\


On the chance that there was still some fat-fingering of the "letters", I looked up specs for a 1978 GS1000.

They had a 15-tooth front sprocket, a 42-tooth rear sprocket and a 630 chain, but I have no idea how many links.

If you have converted to a 530 or 520 chain and sprocket, those numbers are all wrong for you.

To maintain the same ratio, the sprockets need to be 18/50 or 18/51 and the chain needs to have more links.

.
 
can you explain why the larger gears would revert the bike to stock?
 
They are not actually larger gears. It's all in the numbering.

A 630 chain tells you that it is 6/8 of an inch from pin to pin and 3.0/8 of an inch from side to side.

A 530 chain tells you that it is 5/8 of an inch from pin to pin and 3.0/8 of an inch from side to side.

A 520 chain tells you that it is 5/8 of an inch from pin to pin and 2.0/8 of an inch from side to side.

Because the pin-to-pin distance is smaller, there will be more teeth around the edge of a same-diameter sprocket.

Because the pin-to-pin distance is smaller, it will take more links to make a chain that is the same overall length.

If you simply use the same number of teeth when you convert to a 530, the sprockets will be a smaller diameter, and your chain will likely rub along the swingarm.

ok i understand now
no one ever explained that to me before

and with that a little math and a little bit of fun with
gear commander i can figure out exactly what i would like to have!
 
You would have to consult your service manual for that. :o

It's on page 1-4 of the factory manual, which is page 11 on BassCliff's pdf version.

Just so you know, that is the FINAL drive ratio, not the PRIMARY. :-k

Here is a cut-and-paste from the factory manual:
