I think the upper arm lever (part 06.0027) on the front drum brake needs to be flipped 180 deg so that both the upper and lower arms are parallel to each other. To achieve this you may have to increase the length of the cable and also the connecting rod.

Finishing touches waiting for tank & side panels:- Great to remove the protective layers:- Wiring etc. tidied up, just need to fit tank and side panels then hopefully MOT and register in the UK - weather permitting!
