Changing GS650GL Shocks

What's up GS community? This is my first time posting, and if it's a bit of an amateurish question, I apologize.

I just recently bought a 1982 Suzuki GS650GL, and I need some input on the suspension. I'm trying to decide if I should get longer rear shocks for my bike to raise it a bit. However, due to it being a shaft-drive, there is that lingering concern where it might damage my bike because the drive shaft will be reset at a slightly different angle. GS650GL's have 12.5in shocks, but a normal GS650G has 13.5in shocks. Don't these two bikes share the same structural frame, with minor tank/seat differences, since they're just sub-models? Doesn't that mean 13.5in shocks will work on my bike? Thanks!
 
At a guess I would say you're right.... :)

There might be slightly more stress at the extreme of the shock extension but I shouldn't think it will be at the limits... Try it & see :)

Hi Mr. hoburger,

Raising the back end will quicken up the steering. I believe the stock shock length for your bike is 325mm (about 12.75 inches). So installing 330mm or 335mm (about 13 - 13.2 inches) would be my recommendation. Any more than that might be too weird and twitchy.

Now let me hit you with the "mega-welcome". Reading all the information in all the links will save you lots of time and money, cure baldness, make you taller, cure insomnia, and turn you into a chick magnet. Seriously. :)

If you are here you probably have a 30 year old motorcycle that needs about 20 years worth of maintenance. You'll find all kinds of helpful tips, procedures, manuals, diagrams, "how-to" guides, etc, in the links below. Let's get started.

Let me dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

My 81 gs650L has 13.25 inch rear shocks- unknown if they were stock or later added. Forks are at the top in triple tree- no signs of "twitchy", but most of my riding has been done on dirt bikes, so I'm use to knobby tires - I'm still getting acquainted with street bikes.

Well, I can't say for sure what the stock size was, but my son's '82 650L has shocks that are 12.75" from eye center to eye center.

I think they are more than .25" longer than stock, though, as they bike REALLY leans when it's on the side stand. :eek:
