Thanks totalshell, very helpful, but whats the rule regarding pre 65. If you fit a D14 engine wont that be later the 65?, Is that allowed. Just how standard do they have to be? 
Are you saying the D7 engine is U S for the purpose, or just that the four speed would be better. 
Can i beef up the forks any way. I am gonna fit rear shocks from NJB. 
I would like to put double tube set up under the engine, and bash plate, will this weaken it too much? 
Anyone out there with photos of their own banatams ? 
Thanks for the help, maybe in the not too distant future I can post my own photos.
