Clutch slipping
- Clutch cable incorrectly adjusted (see Chapter 1).
- Friction plates worn or warped. Overhaul the clutch assembly (Chapter 2).
- Plain plates warped (Chapter 2).
- Clutch springs broken or weak. Old or heat-damaged (from slipping clutch) springs should be replaced with new ones (Chapter 2).
- Clutch release mechanism defective. Replace any defective parts (Chapter 2).
- Clutch centre or housing unevenly worn. This causes improper engagement of the plates. Replace the damaged or worn parts (Chapter 2).
Clutch not disengaging completely
- Clutch cable incorrectly adjusted (see Chapter 1) or faulty. The inner cable could be seizing in outer cable, caused by dirt, kinks or incorrect routing. Check the cable and renew if necessary (see Chapter 2).
- Clutch plates warped or damaged. This will cause clutch drag, which In turn will cause the machine to creep. Overhaul the clutch assembly (Chapter 2).
- Clutch spring tension uneven. Usually caused by a sagged or broken spring. Check and replace the springs as a set (Chapter 2).
- Engine oil deteriorated. Old, thin, worn out oil will not provide proper lubrication for the plates, causing the clutch to drag. Replace the oil and filter (Chapter 1).
- Engine oil viscosity too high. Using a heavier oil than recommended in Chapter 1 can cause the plates to stick together, putting a drag on the engine. Change to the correct weight oil (Chapter 1).
- Clutch housing guide seized on input shaft. Lack of lubrication, severe wear or damage can cause the guide to seize on the shaft. Overhaul of the clutch, and perhaps transmission, may be necessary to repair the damage (Chapter 2).
- Clutch release mechanism defective. Overhaul the components in the clutch cover (Chapter 2).
- Loose clutch centre nut. Causes housing and centre misalignment putting a drag on the engine. Engagement adjustment continually varies. Overhaul the clutch assembly (Chapter 2).
