Thank you, although I am fairly sure the engine is not the same as a YB 100, although that part does look close to what I need. I think the RXS100 may have the same engine. My main worry is why the part broke in the first place, and so I'll have a look at the clutch to see if anything has come adrift. Hopefully this http://www.haynes.com/products/productID/373 will be helpful.

Here it is:

The bike was registered in 1984 and it is a 98cc two stroke. I have the engine number if it would be of any help?

The AG's were primarily designed for agricultural use in New Zealand and Australia, so there are lots of them over there and very few here. There are lots of agricultural bits like dual stands, a clutch lock, low first/second gears lots of racks and crash protection. It seems like a very sturdy bike although I'm not sure why they went with a two stroke engine, is it a Yamaha thing? I'll try to get some pictures up, and maybe start a thread in the projects section.

I understand what you're saying about the 'one hit wonders', the friendlier forums are always nicer. As for the problem with the bike, I think pictures would explain it far better than I can, so I'll get some pictures in the morning when its light. One thing which would make things a lot easier is if anyone knows if the AG100 shared any engines with any more common Yamaha's sold in the UK?

Fair enough, will do so! I'm fairly local to you by the looks of things, I'm over by Corsham.

Hello all, Recently acquired an AG100 in need of recommissioning, so no doubt will be looking for plenty of advise. I've previously owned a CG125 which was good fun until it fell apart. I'm looking forward to trying two-stroke ownership now!

Hello, I have recently purchased an AG 100 which has had the clutch screw/worm shear, probably as a result of the clutch seizing. I am struggling to find a replacement clutch screw for the bike, am I right in thinking that the engine is the same as that on the RXS100? Any pointers to anyone who might be able to provide a suitable replacement would be greatly appreciated.
