I found a 86 honda fortrax 70 for $100. Im going to get it friday. It runs but has a problem when you shift it. It makes clicking noise. Does anyone know where I can find parts diagram for this quad and parts? Is it worth fixing? My son is 9 and 7. It will be small for the 9 year old but I was thinking if it runs and I cant fix it I can alway part it out.

I would appreciate any thoughts on this project.

Thanks,
