Scooterotica

If theyve been in a while its probably just wear n tear

Loads of shitty Cosa spiders around so what you need to do is whip it out and measure the depths of the turrets. Chances are you'll find they're around 21mm deep and they need 22mm so you'll need to file them down to allow it to disengage properly.

Right just replaced the worn clutch steels plates with new ones, and I’m still able to ride my PX with the clutch pulled in. It was all put back together properly and the cork plate had soaked in gear oil overnight and wiped down before building everything back up.

Any ideas to what the problem might still be?


cheers

did it work ok before you changed the corks ? or was it a clutch you have just brought to fit in your scoot ?

My scooter actually broke down, it was whistled trying to diagnose the problem the cork plates were changed. Turned out the piston was badly warped, as shown below.

May not be a contribution to the cause, but am I right in thinking that the mallossi rings should go on the piston a certain way?

What about the spacer cog washer is that in correct and is the oil pump cog lined up with the spacer cog. I would also check the brass plunger, pressure plate ect. If you have been out riding on the scooter the piston rings will be damaged if they are on the wrong way, I would imagine. I believe your problem lies with the clutch.

Changed the brass bush and shrim on the clutch, seems to be 100% again. Think the problem might have been too much gear oil on the plate, causing them to stick. It’s still a bit sticky in 2nd but a lot better than it was. Think the initial problem with the warped piston may have been a loose exhaust due to bumping over speed bumps and kerbs.
