Since the engine was running I started it to warm up the oil before draining it. Theres not much oil.. about 500ml is what it takes.
Next job is to remove the footrest, you need to remove the 14mm bolt (which has a 14mm nut on the other end) and 12mm bolt which bolts in the body. Yamaha conveniently mounted the main stand on the body so you can still work on the bike without resorting to other methods to keep the bike upright. Once the foot rests have been removed, you need to either remove the exhaust or remove the right footpeg rubber. I decided to remove the exhaust as its simple enough.
I then removed the outer cover, this reveals the carb, clutch actuator and two-stroke pump. These are easy enough to remove. The hose needs to be pulled out of the oil-pump and withdrawn from the airfilter base. a bit of oil will come out, raise the end of the hose higher that the 2T tank (or oil level in the tank and the oil will not flow. I secured it to the oil-tank knob with a zip-tie.
Once that is done I removed the inner cover, bit of oil will leak out so have some newspaper handy. This will reveal the clutch. There are six bolts .. remove these evenly with a 10mm wrench. You will notice some rubber spacers between the clutch plates, these can be gently peeled off. Next you will find a 20mm nut which holds the clutch hub to its shaft. This is where I get stuck. On most bikes you will hold the clutch basket with a simple tool but here you need to hold the hub stationary while turning the bolt. I can get the hub to stay in place by putting the bike in gear and jamming the rear wheel but these bikes are lightly built and there is a strong possibility of breaking something. I probably need to make a holder which bolts onto the six screw-posts in the hub. Anyway I'll stop here and check around before I break something.
Here's some pictures of the clutch basket and hub.
Stay tuned!
