Don't know which of these companies copied or were infjluenced by whose design first, but Doves', H-M's and now yours all sound like they're based on a similiar design.

I think you'd like to be able to buy all the parts with the comfortable assurance that everything will fit and mesh when it comes time to assemble the engine. However, I think this is something that may have to be fit, and re-fit, on the engine itself, with runs to parts stores or industrial supply houses in-between for parts. If you don't have the sprocket for the crank, which seems to be the critical part you're missing, I'd still suggest you call Dove as, even though they're not making the complete setup, could probably provide you with the needed sprocket or at least the appropriate sizing. If they go cold shoulder on you, let us know. It's always good to get actual vendor-attitude feedback.

As for waiting since 1993 for your system, Dove always wanted cash in advance. Did you actually send them money for this. If not, then it's not on order at Dove.

Good Luck
