I did the standard "spring plate" conversion where you replace it with the two steels and single friction plate. I'm finding that I have a slight squeak from the clutch area when I take off from a dead stop -- doesn't happen any other time and seems to go away as the tranny warms up. Anyone else experience this? Is this normal for the "spring plate" conversion?

Thanks

Sloppy did you adjust your belt since your last ride?

The "SQUEAK" is your rear tire starting to spin ...

This is what happens when you PRODUCT IMPROVE your clutch which is now basically a "RACING CLUTCH" and you now have to relearn how to clutch off from a start or you will constantly get this "SQUEAK" ...

Sportsters have not had this "SPRING PLATE" since 2001 and the BLAST/XB's never had it ...

It's been a year since I adjusted the belt (since last tire replacement) and it is on the purposeful loose side.

Never thought of the tire being at fault. I do notice that if I feather the clutch from a stop it doesn't happen. If the XB's don't have the spring plate though wouldn't they also squeak from tire slip?

If you want some Drive Belt adjustment "INFO", e-mail me

"i" will e-mail it to you ...

You will find it very interesting and informative ...

"i" have a blast and if "i" get in a hurry
it "SQUEAKs" ...

IMHO,this phenomenon has absolutely nothing to do with belt adjustment or tire slipping.
I´ve had that squeek too.
Think it´s a bad idea to combine new plates and old ones.Mine were 40k kilometers on the bike before I tried to get rid of the spring plate.
The minimal difference in the thickness of used and new plates let them not all engage at the same time.This causes that the clutch slightly slips at first.On the first moment,only the new plates engage.
It´s only my theory,but I think it makes sense.
Hacked of that sound,I proved my theory and changed to a stack of all new plates from Energy One.No enervating sound since then

Beg, to differ with you ...

Up-dated my clutch with used plates a 45K miles and my 97S3T has over 100K mile on it now ...

Hey Ralph have you ever had a "lurch" or a shudder event on take off?

Interesting theories -- I'm not sure I'm buying the "tire slip" theory as the squeak doesn't happen with XB's.

I'm leaning more into the thickness difference, though I'm not sure of the dynamics as to why it would squeak.

From muscle memory it also seems that the "clutch window" at the lever has shrinked a bit...

Mine squeals abit too, sounds like a fan belt slipping.

on ocasion the bike will lurch, this is more pronounced on a long slip take off.

and it only happens in first.
the throw of the lever does get shorter, with the grenade plate out.

Jim,I never experienced any shudder only that squeeking sound.

LaFayette,in my eyes your statement is no contradiction to my theory.

Yes, exactly like a fan belt slipping! And only in first with a quick launch. Fanning clutch prevents the lurch.

So, next time there's discussion on replacing the "grenade plate" (boy, what a great name -- I wish I thought of that!) it sounds like we should offer the advice of replacing all the friction plates at the same time.

I recognize it's not happening to everyone, but there might be a trend. Similar to how we on the board discovered potential problems with GL-5 gear oils.

"grenade plate"
LOL!!!

I hate that thing. Just seems like a bad idea. When mine fragged it ruined the clutch basket too.

Word is that older barnett extra plate clutches weren't as thick a stackup as the newer ones are. A local customer was having bad engagement point problems and aa bit slip with his older one, Barnett sent him an updated one and he's a happy camper now.

MY additional plates are stock ones.
The bike started lurching before the changes, it also shudders on hard (loft the front wheel ) take offs ( I think belt slip / skip )

has any one over filled the gear box and had this happen?

can the primary chain do this?

I put the Barnett x-tra disk clutch pack in about 6 months ago. I can not find a good adjustment. Never been happy with it. Drags or slips.(junk) I've tried adjusting it dozens of times, by the book. Hot/cold makes no differance. I even pulled the pack back out to double check that it was installed right, still the same. Not a happy camper, I've been thinking of going back to the granade plate clutch, least I know it works fine,on the street like it was designed to.

The OEM TUBE FRAME clutch with the SPRING PLATE removed and PRODUCT IMPROVED is exactly what the aftermarket clutch is !!!

I did the upgrade last year and had the same squeal. It was for sure the clutch plates. I could feather the clutch on take off and make it squeal longer. I could even make it squeal between gears if I miss-matched the engine revs. Finally took the plates out and put the frag plate back in. Squeal is now gone.

Would getting a full set of fresh factory friction plates do the trick or would you perhaps also need the steel plates as well?

Great information here folks -- a little late for me but hopefully it'll help others.

The SPRING PLATE(AKA FRAG PLATE)was put put in so the Clutch had a SOFT RELEASE ...

Removing the SPRING PLATE gives you a RACING CLUTCH and when you release it you should be ready to move "NOW" ...

"AND" you have to re-learn to use the clutch release function all over again ...

Sloppy,
Funny you should mention the squeek.
My S2 started doing the same thing after I relaced the spring plate a month or so ago.
I had to replace the stator so I did then clutch since I had a USED clutch pack laying around (thanks Fireman Jim!).
I checked the S2 plated (metal and fiber) and the ones I used to replace the spring plate.
They were so close in thickness if you mixed them up, you would never know the difference.
Yes I used a mic, not eyeballing....

The clutch works better, the sound is definately coming from the left side under the derby cover. Not tire chirp.
It's no big deal, I'll put up with it....

Really straight forward to do.
Remove clutch pack from bike.
Open up clutch pack (need some special tools to remove diaphram spring retaining clip).
Remove fiber and metal plates until you get to the middle of the clutch pack.
The center plate is the "spring plate".
Remove and toss the spring plate.
Replace with 2 steel plates and one fiber plate.
Put everything back together!

Of course this is the Readers Digest version......

The suggestions discussed here would recommend that you purchase all new fiber plates to prevent the "squeal".

To replace grenade plate you need TWO new steel plates and ONE new fiber plates.

You should also purchase a new retaining ring that holds the spring plate to the hub -- not sure of correct PN, perhaps someone else can help? It's very confusing in the parts manual.

Chevy dude,
I also made my own tool and used the quill on the drill press to push it down.
I simply rolled a ring out of 3/16 steel and used a piece of 1" square tube put across the ring.
Then pressed the whole thing down with the drill press (not running of course..)

I'll post a picture when I get a chance.

Phew, went out to the garage and checked. I do have two steel and one fibre. Don't know why I thought it was the other way around. Maybe having them laying around so long is the problem. Get the job done.

The 'squeak' is definitely from the clutch when the spring plate (or as Oldog accurately calls it grenade plate, as like when Al's went mine too ate the clutch basket) has been replaced with 2 steels and a friction plate.

I guess I was lucky both of my bikes have the spring plates remove without the noise issue. I'm interested in what you have to do to stop the noise.

Update on shudder POPing sounds,
I removed more belt slack it now has just short of 2" free play wheel off of the ground, I lubed the clutch cable and re adjusted it, and tried a new approach on axle position adjustment. Hope that this will make it better, I think that the primary tension shoe on my bike will be replaced next IRAN cycle. If I have a better work space the gear box may come out for a look more later.

I replaced belt and sprockets as a set and have issues with less than 3k miles, the hard chrome is already flaking off of the rear sprocket.
