    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.

On the highway my revs are around 4000 rpm when going 60mph (or so). What could I do to bring the revs down? Could I change the gearing somehow?
 
I know there's a rear gearcase swap you can do, but the donor model is pretty rare (1100GK maybe?) -- someone should be along soon with specifics.

Just rev it and don't worry about it. An 850 will cruise at 85mph and 6,000+ rpm all day and all night with no problems.
 
I used to think the same thing, but at 70mph doing 5000 rpm, the bike is perfectly smooth and has lots of power on tap. It only sounds like it's working hard.
 
The ONLY way would be to change the rear differential THE common gear ratio is a 3.09 if I remember Some of the 83-84 1100GKs had a 2.9 gear ratio. The 1000/1100 were regeared in the secondary- beveled drive gears. They are not interchangable. IF you could fine one I don't think you would be happy with the results The 850 needs to have some RPM's to get it's power. What Suzuki should have done was to give it an overdrive 6th gear

I'm gonna have to third this one. I've considered the same in the past with my 850. I can buzz around town like a banshee but short-long trips feel like the engine is working to hard at cruising speed.
 
I remember riding a GS 1000 that seemed to rev (highway speed) at a much more comfortable RPM. This is my second GS 850G. The first was a 79... rode it from coast to coast... never any problem, except for the high revs and the reletive high gas consumption. As it is I guess I'll just leave things as they are and drive at a comfortable speed. (A sixth gear would be great though!)
