strong burnt smell, cracks in friction material, if you put it in any gear and the car doesn't move or takes high rpms to make it creep.. the burning smell is always the dead giveaway without pulling the tranny..
bad clutch cable, or not enough oil on the clutch plates.
there should be 6 clutch plates
There are various ways through which you can know when your clutch is bad. When you are having troubles shifting gears, this might be a clear indication of a clutch problems.
Slipping of the clutch and a peculiar smell are the first signs of a clutch that is worn out.
If the clutch is operating normally, there is no need to replace clutch plates. If the clutch is slipping and cable or hydraulic operating method is working correctly, oil is of the correct grade and in good order & clutch springs are within manufacturers tolerances, the probable cause would be worn clutch plates. Measure both friction plates and steel plates to determine whether just friction plates can be replaced & dont forget to soak new friction plates in oil before fitting. Unless you know what you are doing and have the corect tools, I would suggest it is a job for a motorcycle dealer (such as ourselves - www.aprilia-merseyside.com)
It is important to know the signs of a bad car part. If an AC clutch bearing going bad, the biggest indication would be the trouble driving with the AC on in the car.
Are you replacing a whole clutch or just the clutch plates?
The clutch will be very loose and it will be hard to come out of any gear.
There is more than reason. A clutch has plates that engage and disengage. The plates can wear out , often mostly due to riding the clutch or other improper operation. The clutch also has bearing and springs- if any of these breaks, the clutch fails.
The clutch is non-adjustable. It uses hydraulic fluid to release the clutch. If you are experiencing a dragging clutch, check your plates for warpage. This bike uses a 'slipper' type clutch so having the correct plates in certain places is important. If you have not changed your plates and they are the originals, check that the clutch fluid doesnt have air in it.
To replace the clutch plates, drain the oil, and the right side engine cover has to come off. Then, remove the clutch bolts in a criss-cross pattern, slowly releasing the pressure on the clutch plates. Usually just the fibre plates are replaced, the metal ones may be ok. Buy a clutch rebuild kit with new springs, plates, and cover gasket.
when a clutch goes bad the bike will not be able to go top speed or let the rpms get to high in any gear because the clutch is engaging when it is not the right time hope that helps
