nick1 Posted September 29 Report Share Posted September 29 (edited) The clutch will probably slip. At high speeds there is vibration and the motorcycle does not move! The size of the package is 25.8 mm, I checked the feredo in place and did not lag behind the disk. Spring size 37 mm.

lemur Posted September 30 Report Share Posted September 30 (edited) Found this: The steel ring in the photo with printing on it appears to be a spacer to make the clutch pack thicker and the fibre plates are not black they are the colour of organic friction plates. These look a lot like your clutch, if your clutch pack is undersized it could be you are missing that spacer. Oil should never be as black as those plates or the oil has been burning in there for a while. Personally for the cost involved I would replace the clutch pack with stock parts and be done with it. add: There are only 3 friction plates in this set because it is for a newer model GasGas, so no I am not suggesting this is the right part for your bike, I am suggesting a previous owner exchanged the originals with something that apparently does not work.

It would probably help him if he bought a new set of SURFLEX plates to have the correct pack thickness to start with for the old VILLA based bottom end and then go through the slave and master cylinder push rod set up to get it working plus try using a clutch /gear fluid that is less high tech , there cannot be much wrong with it.

Tr1AL Posted October 1 Report Share Posted October 1 @ nick1 You could try putting some washers/shims on the clutch spring bolts to preload the springs and make it push the clutch pressure plate more stronger on the clutch discs but really you need a new set of clutch discs to make the clutch pack thicker/wider.

Surflex plates will look like normal organic clutch plates, I really wonder if he has a mismatch of parts now, I can't imagine the original plates have cross hatch spaces like that. Are we even looking at carbon fibre discs and is that why they are so black? Cork or paper discs should clean up to be cork colour like in the pictures of new ones and nothing in a 2-stroke transmission should make the oil and pads stain black unless it is from burning.

I’ve already done this, but not for the bolt, but instead the part of the clutch itself where the spring is in the aluminum part, I ground it by 2.5 mm, but it didn’t give anything. I’ll buy oil and I’ll exhaust it. Do you know what the length of the spring should be? Quote Link to comment Share on other sites More sharing options...
RonH Posted October 1 Report Share Posted October 1 (edited) Found this photo of Surflex clutch plates to fit your bike and they look nothing like what you have. My guess is that someone put in a pack for another bike that was “close enough” at least for a while.

I could not stand it any more and checked a old gasser motor that was sitting on my floor. Those are the stock plates. I still think its not correctly installed or those plates (friction are bad). Buy a whole new clutch and move on. Where I live you can order with an expected delivery time of 4 months! The disks were installed correctly, I couldn't confuse anything.

All the fools gave the same recommendation, replace the clutch pack with new stock parts and be done with it 👍 1 Quote Link to comment Share on other sites More sharing options...
nick1 Posted October 15 Author Report Share Posted October 15 Thanks everyone for your help! I bought 5w30 mineral oil and machined the rings so that the springs would press the clutch harder, but it didn’t help. The problem is probably in the carburetor!
