GG Clutch basket photos

No one wants to hear this, but the ONLY time my clutch has squacked has been when I have been in way too high of a gear. Once I shifted into the correct gear, I have never heard the noise.

I am not the least bit concerned about this so called issue. If you want to hear clutch noise, ride a pre-09 Husaberg. They squeal like a pig if you arent in the right gear.
 
So now the fix is that you have to ride them the way someone else thinks?

I find it more than a little troubling that the dealers on here say it is fine but the customers have an issue with it. And at the end of the day the dealers say buy a different bike...they all do it...Bullcrap.

My 01 doesn't do it no matter how much I chug it. The torque of the GasGas is the reason you can ride a gear high, and it is negated by a terrible sounding squeal if you try. Now I can't ride it like that because someone says you aren't riding the bike the way they set it up?? GasGas needs to fix this. Clay said a long time ago they would look into it.

All that I have seen done is that threads get closed down and the posters get humiliated because they want there bike to perform like many others they have had...CRAZY.
 
I think the reason removing the webing works, is oil is forced up into the plates when the fingers spin downward into the oil bath. If the webbing is there, the oil is not forced in. and centrifigal force will just spin the oil out. All I know is it works...holes in the inner hub probably help too, mine may have them now that i think of it.
 
Who is humiliating you? A difference of opinion or a different conclusion to an issue is not humiliation. One thread was closed after many posts and no real progress, nothing was deleted. Also, the tread with the photos was made a Sticky. It also contained what I consider a full history of the clutch design, some thoughts, and proposed changes. Some guys have made mods that helped or cured the problem.

Some have issues some don't. There are different styles, different setups, and different bikes. We know there were changes in the basket. I'm not saying there isn't an issue but I am saying its not an issue for everyone.

Lets be positive. Since you have two bikes and the problem, it would be interesting to swap pressure plates, inner hubs, and baskets separately and see what has the most effect on your problem. Also note the differences.

I'm in the camp of more oil is needed through the pressure plate/inner hub. The basket will always spin at the primary ratio X RPM, the inner hub slower if slipping and not at all when stopped. The basket will always try to move oil out through the plates from centrifugal force, it will not scoop oil in on the outer edge. The more oil available to move(in the inner hub) the better(to a point).

Think how a squirrel cage blower works, same idea.
 
As the clutch squeals....Just a thought, It seems that only the newer models with webbed basket are having the squeal (and only some of them), is the earlier clutch setup interchangeable ? Has anyone tried to swap and see if it helps? My '06 has never made a noise. Just thinking out loud....
 
Everything should be interchangable. Worst case is the washer under the basket gets adjusted to maintain the same height.

1)Are new pressure plates different?

2)Are new inner hubs/oil hole patterns different?
 
It would be good to get some clarification from the factory on what is causing this since so many are complaining about it. It's all well and good for owners to be shot-gunning parts trying to isolate the problem, but testing and fault isolation is the factory's obligation IMO . . . not that if I had the parts I wouldn't go for it myself as well. Maybe they are still looking at it. I agree if they make a nasty racket that could lead to bad press at events where lots of owners of other colored bikes hear, so they should be concerned if for no other reason.

From what I have heard it's more of an annoyance than a functional problem, so that may explain the advice. I haven't been able to ride mine enough yet to know if it's going to be a squealer or not. I've had issues with lots of bikes over the years and those were always functional problems, so I don't see this as a major concern as long as the clutch performs. I'm sure I'll be annoyed and determined to fix it if I got one.
 
I have read posts on the KTM forum about clutch squeal and have heard of some Jap bikes doing it too. My 03 200 did it once but I was slipping it like crazy to make it up a hill of leaves and marbles with a crappy rear tire. I have not heard anyone's new bike squeal so I don't know if we are even talking about the same squeal but in my opinion if it's not burning clutch plates or hurting anything I could care less if mine squawks.
 
I did'nt mean to stir things up with this post , if I did , my apologies , its just that I have never had this problem with any of my bikes in the past , I just want to solve the problem of the squeel hence this post however I dont want to modify anything that will couse even more problems in the long run . I am still leaning towards drilling more holes in the inner hub , also waiting for the local importer to contact me with a reply from the factory.

This is not a normal problem and I will not live with it .

Try swapping the clutch plates around. It has resolved the squeeling on some bikes.

You mean turning them around and then installing or putting the front plates at the back and vice versa .

One of the mechanics at the dealership close to me phoned me and told me to check that the steel plates have the sharp edge to the back ( they are blanked and have smooth edge one side and sharp on the other side) he also mentioned using ATF , can this be right , can ATF be used?

I use ATF+4 in mine. It squawked with motor oil in it but has not since the switch, however I think it has nothing to do with it.

Yes, no particular order. It worked on my 2001 GG and a friend of mine's 2008.
 
FWIW, I went through the clutch on my '07 this winter. Everything looked great, no notches, plates in spec, etc. Also no previous problems, typical GG clutch. Before I reinstalled the pack, I went over the edges of the friction plate tabs with a fine jewelers file, and the edges of the steel plate tabs with a small sharpening stone. Nothing seemed to be too rough, typical as expected. Last weekend I finished the bike, and having no Rotella 5W-40W I filled the trans with the 15W-40W, which I use in summer more. It was in the 40s so I figured the clutch might drag and clunk when I put it in gear. Well, I was stunned at how little drag it had, it was a major difference, even with the heavier oil in the cold weather. I could easily go in and out of neutral while the bike was still cold. I can't help but think there is something to this, allowing the plates to float as free as possible in the basket and on the hub.

The edges could be the point, squeal is vibration through a thin edge, hum is vibration through a thicker surface. If the sharp edges are dragging, even if they are dragging on the basket, it very well could cause a squall. Unfortunately not all are willing to be as precise as you Glenn so time will tell. It would be a simple task to pull the cover and plates, do as you did, if they laid it on the left side they wouldn't even have to add an oil change in there. I have dealt with many 'noise' issues in my 30 years as an auto tech and could tell you some wild stories about what can make a noise
 
Chirping clutch

Hi All

My clutch chiprs under hard use, is this a normal thing with GasGas clutches? The plates are well within spec, it only happens on big hills in deep mud etc
 
I would have no problem spending that time if the only benefit was that it shifted more smoothly and found nuetral easier. Good wet weather project.
