Why do my fork springs squeak??

Peeking out from my bunker, to use the '04 springs didn't the spacer length have to be altered? How is the preload set and what is the static sag? Back into the bunker...

TWN, I understand we all kid around here. But when the family gets involved....well you know what happens.
Cute though it may be, your avatar could have been sourced from any one of a million places hosting funny, cute or otherwise pictures - how the hell would we know? (Unlike Howie's, which we all know is a self portrait of hisself.) If you don't want your family involved, don't involve them. No diss, but that's what I would do if I had youngun's. ;)

 
Doing a little checking, found this. While it addresses the fact that the 04's have more length, it says nothing about diameter. He does mention his springs were installed close space coils at bottom, this is opposite to what I recall the orientation should be. The only thing I can think of that would cause a noise is contact between spring and tube, or spring and damper rod (doubt there's enough room in there for the spring to be that offset though). I would check to see that the spring is indeed centered on the cap, not ****-eyed so that it rubs on the tube during it's action.

 
I don't recall ANYONE EVER mentioning to me that my avatar might be a problem.
Look, *******...

You're the one that made your avatar an issue. Shall I quote you?

Don't go there, fucknuts. That happens to be my daughter, you piece of ****.
Yep...that's the way I recall it.

So, YOU make it an issue of someone referring to YOUR avatar, which YOU chose to use, which YOU chose to make out of a picture of YOUR daughter. To which you go all apeshit over when TWN mentions it.

And you call ME an ****** and TWN fucknuts and a piece of ****?

Take some responsibility for yourself.

Personally, I'm a little disappointed in TWN for not dogpiling your gutless *** for going off on him for no reason.

 
Man. First Scab, now you? Where's my bottle of Jack and vial of sleeping pills? :blink:

Man, you've got two bullets now. Put one in your pocket and, well, you know what to do with the other one.
Yer kiddin, right? Andy took the firing pin out, so that option doesn't work. :****:

The mockingbird finally gets it?

Um, that problem has been, uh, solved. Thanks, by the way, for the tip. ;)

So, was it the little round ball treatment or the sticky stuff? --=Congratulations=-- For you new comers to the Forum this is the topic, click here: spoonfed And FJRandy thought his forks made noise!

Um, converted to whole walnuts. This is California, afterall. :wink:
Just because it's organic doesn't mean it's safe. Take cobra venom and poison ivy for instance. :eek: So, you've been telling your PETA neighbors your bird just went nuts and left?

I'll thank you to stay away for my back... :blink:

Let's just say the little bugger was shell shocked... :grin: ... and what the neighbors don't know...

 
One other thought on the springs. Apparently, there was a bad run of 04 springs. had my 04 in for warranty work,(clunk in forks) as usual the local dealer was stumped. Called a contact @ Yamaha, he spoke w/ the service guys, they said there were some springs that came out a different length and would cause a noise. They sent the dealer new springs and the sound is better. I compared the old springs when they were on the shop bench and you could see a difference in length.

If FJRandy is swapping '03 for '04 springs I can guarantee there is a spring difference. Information gleaned from the same source that Radman suggested here.
2004 Fork Spring Yamaha P/N: 5VS 23141 00 00

Free length: 10.4"

Spring rate: 0-3.58" = 44.77lb/in. 3.59-5.31" = 61.55lb/in.

Coils: 20

2003 Fork Spring Yamaha P/N: 5JW 23141 00 00

Free length: 10.28"

Spring rate: 0-3.58" = 44.77lb/in, 3.59-5.31" = 55.96lb/in.

Coils: 17

Unless he has had an assembly error (you have his WORD, no error) the springs would either have to be wrong, have coil bind, or insufficient preload to make noise. Before this thread took a left turn in Albuquerque I had asked "How is the preload set and what is the static sag?" and haven't seen a reply.

Sorry ionbeam, I didn't see your last post.

You might have nailed it. I didn't change the length of the spacer. But is that really neccessary with a minimal difference in length? I thought it would give the spring a little more preload so I wouldn't have to crank it down as much.

Verrrrry interesting. Now I think I WILL go back in there and see what's up.

Thanks for keeping to the subject. At least I got somewhere with this.

I went back and re-read BAGSTR's procedure and he did not change the spacer length. It was another install of aftermarket springs that changed the spacer length by ~50%! Do check your preload setting and static sag because this will show you if you have a problem vs. an annoyance with the noise. Did your springs go in with the progressive windings up?

I just installed Race Tech (roughly 2" longer than OEM) springs and ionbeam may be referring to my post - 50% reducting in spacer length. Well, Slight math error resulted in spacer way too short. The procedure is to 1. extend your forks (spring in - washer either in or account for it later), 2. measure from top of spring to top of fork tube (for me 135mm), 3. on your fork cap run the preload all the way out, measure that part of your fork cap that extends into the fork tube (preload part actually extends into the cap a mm or so) 40mm for me. 4. Subtract measurement from #3 from measurement from #2 (for me 95mm). 5. Add your desired in tube preload (20mm for me), add that to #4 and that's what length you cut your spacer to. For me, 115mm. I originally subtracted the fork cap measurement twice for some unknown reason. Let me tell ya, when the springs are just about totally compressed when you hop on, you can definately tell something is wrong.

I probably described the above in my usual convaluted way - all you're doing is determining the measurement for 0 "in tube" preload and then adding the amount of "in tube" preload you want. Hope this helps someone and isn't too confusing.
