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 plate in a TTR 125 drain the engine oil, disengage the engine skidplate and the starter motor. This is a common issue with this model of Yamaha dirtbikes.
lighter oilin my 2005 Yamaha xvs 1100 i use penrite 5w 40 because it helps with the gear change .is a lot smoother because clutch plates don't seem to stick as much.give it a go.
Are you replacing a whole clutch or just the clutch plates?
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.
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.
bad clutch cable, or not enough oil on the clutch plates.
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)
Source http://www.nightrider.com/biketech/hdclutch.htm Q: What causes my clutch to stick or drag? A: There is no single cause of a sticking clutch. Some more common reasons for a sticking clutch are:- Clutch controls are improperly adjusted. Clutch cable is collapsing.- Clutch spring tension is to tight, spring binding.- Too heavy an oil has been used in the clutch. A thick viscosity oil can cause the plates to stick, especially when cold.- Clutch oil is 'worn out' or burnt. The oil has been in the clutch to long, clutch plate wear is excessive causing slippage, or a driving style that slips the clutch. Changing the oil in a clutch often improves the situation.- Clutch plates are warped. Friction plates or metal plates may be warped.- Improper adjustment on primary drive chain/belt.Hope This Helps.
