Where to get preload on suspension increased?

[eSOL]

As of lately have felt that my suspension on the rear could be stiffened up a bit. Just wanting to know a place where they won't charge shit loads or what c spanner Size I'd need to diy? Am located in Auckland Btw.

There is a minute chance that providing information about the make & model of the bike in question could lead to more comprehensive advice being offered.

Nah, fuck it. Get the biggest C-Spanner you can find and a 48oz ball pein hammer while you're at it.

Considering you list your bike as "None" ... it might be difficult.

Pretty sure I've got some spanners somewhere....otherwise careful use with a big screwdriver/drift and a hammer will work.

BUT, I'm guessing the problem goes deeper than just preload, it really doesn't make that much difference, it won't make it any stiffer, just make it ride a bit higher, and make it bouncier.

What EXACTLY is the problem?

hammer and a flat head screw driver...

I have a c-spanner... I'm out west. PM if you need it

[Grubber]

Reseting preload wouldn't be an option i would have thought.
They are usually set up to go and all you are left with, to a certain extent, is Compression and rebound to play with.

Meh, C spanners are for pussies. Get a centre punch and use the 48oz hammer to shift the lockrings.

...i was all full of suspension and to rectify the feeling got very preloaded on vodka and orange...couldn't remember what was getting my suspenders in a twist not long after...then soon I couldn't remember anything at all...it's a common cure I believe...

You sound like Akzle in the red I got from him-'wrong, you are wrong' which only proves more I'm right.

I'd bet the rear spring is way too soft, they usually are on these little jappa's.
I know plenty about suspension, and how it functions, and what each component does, and what effect it has on handling and grip too.
Blindly winding up the preload heaps doesn't cure a soft spring, or a worn out damper either.
It can however cause mucho instability in the bike.....
Not sure which part you think is wrong...
'BUT, I'm guessing the problem goes deeper than just preload' Read above, it's an older bike with stock soft suspension
'it really doesn't make that much difference, it won't make it any stiffer, just make it ride a bit higher' Winding up preload doesn't change the spring rate, so it WON'T be stiffer, it'll just sit however much higher the preload you put in is. And probably top out without any load on the bike.
'and make it bouncier' Try it.....though it may be possible to compensate with damper adjustment if it has it.

You may also note the I asked what the problem actually is before blindly handing out possibly dangerous advice....:motu:

BTW, my take on that 'setup' page is that it's full of bad advice. I'll gladly take that back if Sir Robert says otherwise.

Not needed, Death has done an admirable job leading a horse to water, whether it gets drunk is another matter.

Given all the advice about screwdrivers and hammers I see that butchery is alive and well.......................

There is a tool that isn't a hammer and screwdriver?

I thought you'd seen that 2' adjustable wrench I have hanging on my wall;)


. . .honest, its for bending things & its awesome.

Re read Deaths post. If it makes you uncomfortable then speak to someone who will tell you what you want to hear. But he is 100% correct.

Thanks for the replies guys,


Just a question about the Screwdriver and hammer technique. Can i do it without removing the seat or anything? And there seems to be a latch that is raise into the slot of the suspension, when i adjust it do i need to touch that before at all?

[FJRider]

I have a drill ... totally awesome for lightening the chassis ... :cool:

There is nothing lighter than a hole ... other than lots of holes ... :laugh:

Use too big a hammer and the seat "may" come off anyway ... (along with bits of the suspension)

If you want to devalue your bike use a scewdriver and hammer, I cant believe how rough many people are...................

Rear shock for 1990 Honda CBR250RR MC22, must be in good condition. PM eSOL if you have anything.

If you have to ask, don't do it; send it to a pro like our Tory friend Robert.

I must get me some more holes! (in my bike)

That would increase the size of the problem, thus necessitating an increase in the size of the hammer.

I've only used similar 'butchery' on mine and there isn't a scratch on it, I do use my brains and a soft drift when applying such force though.

:lol: Maybe I'll finally be able to sell that shock!

So went to cyclespot today and matt at the help desk (Fuckin gc) hooked me up for a hook wrench. Went outside and did it out in front of the shop. Rode back home today and it feels like a new bike. Didn't know what I was missing till I was riding it back. If anyone else needs a hook wrench and are in Auckland lemme know and I'll let you use it.

Cool, you have an improvement, which of course is always a term of relativity

I recon... nothing like spending a couple dollars to get the right tool for the job!

Although in saying that I have a wee 20min DVD here from "Keith Code: Superbike School" showing you how to set up your suspension sag and basic damping - they used a hammer and drift to adjust the rear spring preload?

Of course everything is ''correct'' on DVDs and over the net..........................Sometimes you do have to use a BLUNT drift, thats way better than a sharp ended screwdriver on the end of a butchers hand. Its called ''mechanical sympathy''
