Oh, geeze, now I'm feeling all down.
Searches led me back to a recent post by Axl.
wow, i think i just started something...lol 
well, to redeem myself, i think i may have scored another hondamatic crank about an hour away from me. this time i'll hold onto it for when i come around to building this hi-po engine.
if you buy a bunch of small stuff through yamiya, their primary chains are cheaper than anywhere here in america. it's the shipping that kills me. they have the best deal on DID rims but it was an extra $160 in shippping.
M3 used those A cranks. The tensioner is the interesting part.
In 10 words or less, what's the benefit of the "A" crank? News to me but I certainly don't know everything. Quite a bit less. TIA
A better primary drive, a hi-vo chain instead of the two simplex chains. Oops, that was more than 10 already 
While I'm over the limit anyway, here you go: You will of course need a matching primary sprocket on the clutch drive. The early (GL 1000) Gold Wing will work as a donor, their sprocket can be riveted on the 750 cush drive.
As MRieck said, the funny part is the tensioner. Some people just run without one, some use sliders off a Gold Wing, some (as M3) use the hydraulic tensioner and sliders from a 750/900 DOHC model. Needs an oil feed to pressurise the tensioner, easiest off the oil gallery.
Primary chains from a 750/900/1100 DOHC or Gold Wing are all too short, you will need two of them to make one. For those interested, Egli-Racing in Germany has new primary chains with exact length.
Cheers,

Also, the pics I was thinking of were by Lordmoonpie, in his
Ultimate Motor thread.
can only find pics of the modded oil pump right now.
