think the problem is 86/87 model on export were 225cc, so the chances are you need to use the TT350 manual from that year should be the same bar the bore sizes im not sure of the 350 prefix but manuals generally are prefix-28199-70 from that era.
I only have 2 stoke manuals not the 4 stroker however if its the one with the white tank and red fins i think i just sold one and it was a clymers so they made them?
ill see if i have another, but you should be looking for the 350 youll find a few of them prity easy
what info did yoou need exactly ?
