A mate just bought this, it needs a couple of minor bits to pass a MOT but cant get them till we know which model it is. Will also be looking for manuals etc

Frame num: GK73A10237- left the last digit off.
Reg starts with E but declared manufacture date is 1988... according to V5

I am leaning towards GK73 from the frame num?

Yeah, it's an GK73a:-



They were produced in 88/89 then replaced by the GK76a in 1990.

sweet beanerenoes..
now to get a wee listy o bits its owner needs to buy:
side light wiring as this has no side lights fitted.. am hoping its plug in job like my NC29 is 2 short looms each side.
and his other first purchase.. crash bungs!!! anyone know if there are any aftermarket ones than R&G? didnt see much on flae bay.
may see about getting a fighter headlight/windsheild bolt on jobbie to protect the back of the clocks.
