The Continental is still a large lump of an engine , producing a very high C of G in the bike , she'll be a handful to turn , LOL........ if its orientated with the crank axially in the bike, no need for a side stand , just rest her on a cylinder head :-)
Power train will be complex , do they come in left and right hand rotation ..................it'll certainly be different .................I'm looking forward to hearing more :-)
Cheers John

I agree John, the Continental is still a big motor (and that choice may fizzle once I get it running on my test stand).
Rotation shouldn't be a problem. I'm thinking belt off the front of the motor driving a shaft (that runs aft between two of the lower jugs), then using a differential to drive a shaft out to the left side. From there I'd use a conventional HD style primary case, clutch, and six speed tranny using a right hand belt drive to the rear wheel. The rotation can easily be switched in the differential.

Hi Using these numbers en.wikipedia.org/wiki/Continental_R-670#Specifications_.28R-670-K.29 that'll workout at ~540 ft lbs of torque at 2175 rpm , assume a 3:1 stepup belt drive to bring drive shaft rpm up to 6525 rpm that'll bring torque back to 180 ft lbs , then a 1:1 right angle drive to the "standard" HD primary drive , 180 ft lbs at 6525 rpm is "normal??" high hp territory , should be OK :-) With the massive torque available have you considered using less gear ratios , even perhaps a single speed with a fluid coupling , ........was there a special reason for the 6 speed box ?? Cheers John

Thanks John, you're way ahead of me by 'doing the math'.
I was figuring I'd put a tachometer on it once I got it on my stand. I'd like to get it idling smoothly down to maybe around 500 rpm (fuel injected). I've poked around the web and don't see any idle speeds posted, so I guess we'll see. I do know it will sound WAY COOL if it will idle smoothly around that speed.
No particular reason for the 6-speed, other than that's what I'm used to on my Street Glide.
I know I need to think 'outside the box' on this project. Right now I'm just using it as a distraction from the boredom of mudding my Dining Room. I'm still in the research and locating the major parts phase.
I'm ready to go pick up a motor if I find a decent deal on one. Hopefully I won't have to drive across a mountain pass in a blizzard. I followed a little 4wd Subaru across the Siskiyou Mountains a while back. It was at night, compact snow on the road, blowing snow and he was 'yankin & bankin' through those curves at about 40 mph. It's all I could do to keep up with him in four wheel high. I made good time, but it was not a relaxing drive. Don't want to do that again!

Hi This stock? Glide www.motorcycle-usa.com/71801/Motorcycle-Photo-Gallery-Photo/2011-Harley-Davidson-Street-Glide.aspx would only be producing ~45 ft lbs of torque at ~6500 rpm , you'd have ~4 times that , that's a greater ratio than your gearbox low ratio , so no need for a set of gears , one will do ,............... thats all I use in my turbine bike :-) With a say 5:1 rpm range and a top speed of say 125 mph then idling will produce 25mph , some sort of automotive torque convertor in the drive train , perhaps in the initial belt drive at the front of the engine , to provide low speed travel , and a backwheel setup for shaft drive , you can do without the primary drive , clutch and gearbox . Mmmm, "KISS" approach , big radial with fluid coupling at prop mount, 3:1 stepup belt drive down to lightweight drive shaft thru to back wheel with inbuilt bevel gear redux , minimal parts to make, and more importantly , find room for, in the cramped confines of a motorcycle ...............interesting concept , might have to remember that for a future build :-) Cheers John

Would the fluid coupling be better off after the 3:1 stepup? This would affect the size of the converter needed, creep while idling and stall speed. Just put a shorty powerglide on it.

Hi Chris
Yep, definitely better on the "high speed" shaft if theres a convenient spot to mount it , the only reason I was considering having it at the prop shaft was the potential mounting possibilities off all those hefty castings , I guess it will come down to where it can be mounted rather than where it ideally should be mounted , bikes are terribly difficult beasts to build as we have to be able to sit on them and operate the controls without getting "fried" in the process , those bikes with the Rotec engine have a large number of exhausts running besides where the riders leg would normally sit .............not good :-( LOL, after riding ,modifying and building bikes for close to 50 years , I've got to admire those guys that can produce a bike that doesn't have faults , .................. all of mine have had heaps of shortcomings :-)
Cheers John

I guess I'll scrap that Nimbus powered bike idea. I would need stilts or a landing gear to make it work anyway. Faults- gotta love em.

I have a 3350 Wright TC18 turbo componund radial engine with 18 cylinders. This engine it comes in the lower portion of the shipping container. I just cannot find the time or the money necessary to continue my dream of having a running engine display to show at local events and DAV highlights. This would make a great addition of history as these were used on the connies in the later days and are still being used for transport in some parts of the world. This engine is 60" high, 80" long and weighs 3950lbs. It is advertised to have 4200 hp. using the turbos at efficient operation. This engine was cosmolined and said to be a 0HRE. I have need for the money this sale brings of 5500.00 and I will load it for free. This engine will need to be picked up locally. Call andrew at 252-723-1468 or email at andrew@a1mds.com
