I think Delorto was one of the carbs Randakk used. Should run very good. I was going to make a manifold similar to that one to mount single barrel Volkswagon carbs on but sold my 1100 before I got to it.
Lots of things wrong with this description. Side covers are 75-77 False tank Shelter is 75-77 Rims as stated look like 76 ltd. I can not quite make it out but the logo on the side covers could be LTD????
Definetly look like Randakk manifolds, or at least a similar design. Setup properly they will run with some performance improvements over stock.
