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.
