How to compress springs for changing shock preload?

I need to change the preload on my shocks on my Griz 700. The fronts are set to max, and the rears to min. Probably why it feels tippy when going uphill. I ain't "Ahnald", so I can't do it by hand (ok, I tried to for a bit).

What tool have you guys used to compress the springs so you can change the preload? If it's a "specialty tool", I'm looking for something CHEAP, as I'll probably only do this a couple of times, and then never again.

I used a large pipe wrench. It didn't require all that much power to adjust mine. You can always use a cheater bar for leverage and jack the quad up so that there isn't as much compression on the spring.

Placed where? I would think the jaws would chew up the "locks" or toothed part, and putting it below that, it would seem that the "sleeve lock" would be higher than the sleeve, and again, the jaws would damage that portion.

Most of us have found that using a simple pair of channel locks works the best as Yamaha does not have a proper tool to grab the notches.

Yeah, came close to doing that, but then thought the channel locks are going to chew the notches up pretty bad.

I jacked up the quad to take the load off the adjusters, sprayed some silicone spray on the adjusters to free em up, and cranked away with channel locks, moved real smooth, not much effort involved. I didnt chew up the notches at all.

If You affraid of marks then U can try plumbing chain lock.
On one end it looks like wise grips with a dailer at the end to tight it and on the other end instead of jaws U have a chain like from bicycle. No marks and no deformed adjusters.
But forget the crap above.
Silicon spray, car Jack, reg. Channel lock and rug will do it also.
Once You spray it, give couple for penetration, jack it up so the wheels are in the air- there's not that much tension at this point.

Sometimes it takes force to do the job, and maybe a "suitable tool" to do the job, not always the correct way but sometimes its the only way.

The suitable tool is called a "shock spanner" available at most motocycle shops. Steel ones are the best. Taking the weight off the shocks and a little lube behind the ajusting collar makes the job a little easier but it will take some force to move the collar.

Thanks! :peace: I could not remember the name for the tool (I was pretty sure one existed). Called my dealer, they don't have it in stock, but will order it and it will be here Thurs. $10 + tax. The "half-moon" variety of shock spanner.

I just use a spanner and a piece of pipe I had.
I have my rears at full compression, and the fronts one click softer.
it felt tippy, so when i got the new tires put on, i cranked the fronts down and it rides sooo much nicer, no tippyness.

but that could be partially the tires/rims too. I have them full compress. I'm a Big'un dude. 320+ :)

i hate channel locks as a spanner wrench alternative. a spanner wrench with a pipe on it way more leverage than trying to take spring weight off then using channel locks

i also use the channel locks on my real cars for the suspension too.

so, its a double use tool for me.

but a spanner wrench you can use to turn almost anything round that has a hole in it.

with channel locks you need 2 forces, clamping force, and turning force, a spanner... just turning force...

get the right tool for the right job, even if you only use it once...
