True but as I will be using 17" wheels and chain final drive I am not expecting to be able to use the original scooter gears and may need to make my own straight cut ones.

I can see that 3 keeps the motor turning in the conventional direction, the same direction as the wheels, being anticlockwise in this picture.

Do you know the overall input/output ratio of the reduction box?

I would like to run the variator clockwise on the right hand side of the bike.

My guess is that the variator front pully could be run backwards but the shoes and slots in the rear clutch pully mean it can only be run anti clockwise. Maybe the shoe assembly can be turned around and with straight slots the thing could be run clockwise too.

You like making things hard for yourself. With straight slots, as suggested by Frits and therefore a more or less constant engine speed setup, it won't matter which way it rotates. Clutch engagement may be an issue. You won't be able to use a HIT clutch for instance. As for the axial loads, the only thing that will change with reverse rotation is the load will also reverse. You "might" have to make a beefier removeable gearbox side cover.

And the reason you guys are shagging with a new final drive when you cant get the engine to last for a whole meeting is ????

That has to be the voice of reason.

Every generation has to make their own mistakes, Wob. We old farts have had our share; now it's their turn. (Sorry, I forgot: you're younger than me

).

Might be the one race I'd have a chance in.

Well, after being away from KB for years it seems there's a lot of reading to do! Just jumping to the end of this thread to see what's the latest, and flat out reading everythig to date - I'm up to page 80..: I'm knee deep in two strokes (all sizes) and had a bucket once (XL125S in a CB125T frame - only ever rode it at Ohakea, and it went well - apparently had been a very good machine)...anyway, watching with interest, as I might be needing a bucket soon!
