Title: Need help
Post by: suzuki gs500f on October 02, 2006, 08:00:07 AM
I was lookig at my 2005 gs500f and notice on my stock spring, there are a bunch of number 1-?  what are these number for? I'm guessing the spring is adjustable?  or not?  and if so, what is the best setting?

1- 7 i think, its your preload,
7 or what ever itis is the highest and 1 being the softist, depending on your weight and preferance is up to you how you set it, if i still had the stock spring i would have it quite high as the gs spring is soft

I weigh 205lb and I have it set to 7.  It's still a bit soft, so I have a katana shock in the mail from another forum member.

Contrary to popular belief, that does not adjust the "hardness"; that is simply given by the spring, the only way to "adjust" that is to exchange the shock.

As hmmmnz correctly stated, it's preload. It adjusts sag. How high the tail of your MC is when you sit down, in other words. this influences steering geometry a little, but not hardness of the tail.

So me being 6foot3 and 140 pounds. what would be my best option? also, my fiancee rides sometime. she weighs 155. I'm concerned about the ride I'm about to endure.  from Florida to Tennessee this thurs and was hoping this would make my ride easier.

You want to adjust the preload so that your rider sag is about 30mm to 40mm for regular road riding.

I didn't see anything telling me how to change the settings...

There's a tool in the standard Tool Kit...  http://johnla2.tripod.com/toolkit.html  (8 from the left)

You lock it onto one of the notches and give it a crank...  A HARD crank.

I've heard it's easier to do with a screwdriver, but I've never tried that method.

So, do you want the pre-load to be higher (7) or lower (1) if you are a large rider?

I'm 6foot 3 but only 140ish. what would be best?
Title: Re: Need help
Post by: RVertigo on October 02, 2006, 02:47:17 PM
You set the pre-load depending on what type of ride you want...

Pre-load is kinda (sorta) like adding weight to the shock...  The higher the setting, the more the spring is compressed.

If you ever bottom out the rear shock, you need a higher pre-load... 

If the rear is really bouncy (not swimmy like a Lincoln) and hard, then try a lower pre-load.



Generally, if you're heavier you probably want a higher pre-load...  But, the stock GS shock sucks, so bumping the pre-load may not give you the ride you want.

If Scratch's BF-Screwdriver method is as easy as people say, then you might try a few different settings...  Bump up to 4 and give it a ride... Then bump to 5, then 6, etc...  I wouldn't change it too much at once, since it does make the ride different.

I do noitice that the rear wheel will hop sometimes. so your sayin gi need to bump it up to 5-6?
Title: Re: Need help
Post by: Chilly Willy on October 02, 2006, 03:16:36 PM
Thanks RVertigo, your description of the "feel" really helps.  My rear suspension really sags under my weight, so I'm going to try to adjust it.

Ultimately I need to replace that rear shock.  I've asked before, and Pantablo has responded that a 2001 Katana 600 shock would fit my 93.  Is that the only one though?  Are there other shocks that would work?  It would be cool to have a list somewhere of what shocks would and would not fit in the GS500.

If the rear wheel is hopping, bumping it up will probably make it hop more...

It's probably time to track down that Kat shock.

I installed a ratty, rusty, old '94 Kat shock and it's about 4x as good as the stock GS shock.  The coil-over is thicker and tighter, so you don't need to bump the pre-load as high AND it has a rebound adjustment...  I have Kat shock set to 4 pre-load, 2 rebound and it's about as stiff as I can take (I'm about 180 without gear).  Little hop, sticks to the road a lot better.   :thumb:

It sits about a 1/2" higher and rides about 1" higher.

Hey Alpha... What's that other one that's a straight swap?

+1

When I hit the pothole about two months ago, it was set at "7".  There was more damage to the rear because of it, IMO.
Title: Re: Need help
Post by: suzuki gs500f on October 02, 2006, 06:17:06 PM
So i should set it on or near 1? what about this long trip Im taking this week?
Title: Re: Need help
Post by: Toledo Jim on October 03, 2006, 03:51:57 AM
The +1 meant he was agreeing with what he quoted, not what setting he was suggesting. ;)

As to your question, I have no idea.
Title: Re: Need help
Post by: RVertigo on October 03, 2006, 11:42:37 AM
Setting it to 1 would probably just make you bottom out on every bump...

Bump it up one notch, see how it feels...  Then bump it down or up depending on how you like it...  Repeat.

I tried using the tool to adjust the preload yesterday.  There was absolutely no clearance for me to make the adjustment.  Does Suzuki hire gnomes to work on their motorcycles or what?

I got it to work once...  It isn't the easiest thing in the world...  The "Screwdriver Method" seems easier.

Post by: suzuki gs500f on October 03, 2006, 12:39:50 PM
Yea, I just took it to my dad old repair shop and they helped me. I took one screwdriver and tapped the back portion of the dial with it while the mechanic put downward pressure on the dial. it made the rotattion to one ALOT easier. IMO. 1 seems fine. I am going to try it out this friday when we move to Tennessee.
