Aircooled Monoshocks

Looking for a bit of info as to what it is really, I thought it was an Amigo 80 Now I've got the bike looking at images online I'm not sure exactly what it is. I have front disc and rear drum, 21 & 18" wheels, its fitted with a Franco Morini engine but the bore size is marked as 39mm which I think makes it a 50. Unsurprisingly it needs a new rear mudguard, I've tried the one from my Skywalker and its a spot on fit, which seems to rule it out being a Alevin as i found a reference saying they were close but not right.

Are all the cables the same for all air cooled yamaha mono's?

Can anybody help with jetting for a Mikuni VM26 for use on the Yamaha TY250R? The carb is new and was supplied supposedly set up specifically for this bike but it is way out. It'll barely run past idle it is SO rich, as if the choke is on. Supplied jetting is - Needle 5L8 Needle Jet 182 N8 Main 125 Pilot 35 Slide 2.0 Or at least I think this is right as I can't see the flipping numbers and had to photo them and zoom in as best I could.. Thanks. Steve.
