1 st and second are mad third is long and fourth if you go into forth any slower than 65 it wont pull
any advice greatley recieved

The RB22 likes to rev, especially with an expansion pipe. I reckon you'd be better off with standard GP 200 gearing. ie: 18/47 sprockets which would give you 5.22 final.
You could still use your existing 82 link chain with that

Is it ok in top above 65? If it is, I'd probably leave it as it is.
