Setting pre-load to maximum for rear suspension???

Hey all,

So I want to perform an adjustment to the rear suspension (set it to 7 I think, which would be firmest) because the passenger brackets I had installed bottom out on the swingarm whenever I have a passenger on the bike and go over a "moderate" bump.  

This is what I'm dealing with (as viewed from the right side):



I'm clueless about this, what is it set at right now?  Do I push a metal bar into those holes and turn the whole thing clockwise (when viewed from the bottom)?  I tried to insert something, but bent the metal (as shown in blue).  

I have read posts before on this, and heard someone was successful and found it easier using a long screwdriver to adjust it, rather than a special tool?  Does it need to be long enough that it goes in one hole on one side and out another hole on the other side?  Do I need to loosen anything or do anything else first, or should I just start tugging away?

I used the tool in the GS toolkit...  I just cranked until I could crank any more.  And it was really damn hard to find a place to put the tool and get the thing turning.

It's way better than it was set at... 3?...   ...  The rear shock still sucks though.   :dunno:

As for where the setting is measured...   :dunno:   I could hardly see the numbers anyway.

GSJames

So what is mine set at right now?  Do you have to go to Suzuki to get the tool?

QuoteThe rear shock absorber is adjustable for spring pre-load. Place the machine on its centre stand when making adjustments.

Adjustment is made using a suitable Cspanner (one is provided in the toolkit) to tum the spring seat on the bottom of the shock absorber. There are seven positions. Position 1 is the softest setting, position 7 is the hardest. Align the setting number required with the adjustment stopper. Position 4 is the standard setting.

To increase the pre-load, turn the spring seat clockwise. To decrease the pre-load, tum the spring seat anti-clockwise.

It comes in the GS toolkit...  So, if you don't have a toolkit under your seat, then you may have to go to Suzuki for it...  I think there are a few threads about replacing parts in the toolkit and the rear-shock adjustment tool...

Any idea what it looks like it's set at right now?  If it looks like it's at 1 it might make a slight difference

Yeah, that picture isn't working at all both times I've looked at this thread.

I say run a long screwdriver through there and set it at the highest setting.  Then try it with your GF on back.  Then get on e-bay and look for Katana or GSX-R shocks (my bike has an SV shock on it).  See Pantablo's website for more info on shock swapping.

I am not sure we can tell what it is set on, but then again, I still havenn't seen the darn picture.

Sorry about the pic...  It's hosted on my computer, and the internet connection is being intermittent.  Damn, sorry.  If you retry it a couple times it should eventually come through:

Oh, and of course, thanks for the advice  :cheers:

It is working now.  I can't really tell what it is set at.

You're currently on 5. Since you are tightening, I would also suggest you put the bike on the centerstand so you are not fighting the weight of the bike while you are tightening the spring preload.
The motorcycle is no longer the hobby, the skill has become the hobby.

Power does not compare to skill.  What good is power without the skill to use it?

OK I'm back after the adjustment.  I assumed that the number that directly faces you from either side is what it is set to.  I also looked at what way the bottom "appears" to go, up or down given an adjustment in either direction.

Anyway, it's set to 7.  Going to pick up the GF, go for a ride, and make a review.

BTW what's so funny????

I think the idea that a 160lb person is "super light."  I guess that means at 175lbs, I'm just regular light.   :roll:

RVertigo

Well, if you look at national (US) statistics...  I'm sure 160 is probably on the light side.

On the rear-shock vs weight topic...  I'm 165 and the 7 setting is still kinda squishy. :dunno:

GSJames

Oh also guys, on your GSes, since you've got stock peg brackets for the passenger and everything - does the rear suspension ever cause you to bottom out on anything with a passenger going over a slight bump?

If in general no, I should investigate bowing out my brackets more so they clear the swingarm...  More work! :(
