hi mate they are actually twin 36's on a custom inlet manifold that was designed for the k10 ma10 engine by a german compnay called AM tuning. being a very rare item they wernt cheap, in the 6 years ive been on the MSC ive only ever seen 2 sets of these and i have one of them 
it woulb be easy to repllcate the manifold but quite expensive, bike carbs are the cheapest option with good gains to be had
hi mate they are 36DCNF carbs not 34ich's 34's dont have a linkage avaliable as far as im aware in order to have them work as a pair, they are on custom manifold made by a german company called AM tunig, TBH i dont think we will ever see another set of these again in the UK, in the 7 years ive had k10's ive only ever seen pictures of these carbs until now.
