Thanks for the responses guys. A very kind forum member may be able to help me out.
Mainline - you are bang on buddy

I gave it a test ride and for some reason the clutch was slipping

I tried motographics Iain. They had a few other YZ's but not the one I needed unfortunately.
Thanks Andrew, I tried scaling down a YZ80 one, but it just looked all wrong. The writing became too small

Anyway hopefully I have a solution

I'm happy to share once I have it sorted out.
