hello i to have a 1968 BMW 500 that now has a 1500 single port. I think its a Butterfield. The guy I got it from said he had it for close to 20 years and never had it running. A buddy of mine and myself did the basic stuff like clean the carbs set the points fresh fuel and pull started it with a golfcart. its kick start only and after the initial first time pulling it it useually will start by the second kick. Istill need to clean out the fuel tank due to all the rust in it but in the mean time Iused a 1 gal. gas tank off of my concrete saw. Ido have photos of it and will post if any body would like to see it. thanks

I know the post is old but, did the seller have any parts for sale? Im looking for the rear exhaust manifolds for my bike. These were made by Whitson and or Butterfield and I am desperate for a pair.

The sidecar rig above (a Willis 4's) and the Amazonas in the video below the sidecar rig are both going up for sale most likely next week.

The sidecar motor has only 5 miles on it since being rebuilt as with the new clutch and flywheel.

The Amazonas is also going up for sale next week.

I am keeping the B&B bike.

So does a VW engine bolt right up to a BMW motorcycle? if so what model BMWs?

At 2000 Knoxville vw show a guy rode his BMW with a VW engine adapted. Had special, maybe hand made intake that curve up and under tank with a sidedraft from a Harley, very well done and a cooler front rt side and alt front/left side bottom. He said it had some very tall gearing and rarely run in top gear.

Yes, there is a copper gasket that fits into the round hole of the head for the manifold to seal. There were about three different size ones used. I should have a bunch of them if you need some. The sharp edge of the gskt goes down...let me know. VW mechanic of 28 YRS. Steve

The gearbox/swingarm/drive shaft and even most of the frame are from a /2 BMW (1955-1969). The adapters were made by a company called Butterfield then later Willis.

These conversions have always intrigued me. What is the adapter housing/gearbox from? They look the same between those two bikes.

Found this one over the weekend and it made me think of yours. I have a few more pics, If you want to see them.

Probably a Butterfield-Willis 4

Here's a group for those type conversions. There was also a motorcycle made in Brazil called the Amazona.

You could swap the Type 1 engine for a 1700 Type 4 with downward pointing exhaust ports, use a small Geo Metro alternator, aluminum cylinders and a center mounted 2bbl carb.

Another question, there was no gasket between the carb adapters and the head. There are gaskets between the carbs and the adapters, flat paper gaskets, but nothing against the head itself. What should be there?

Adapter:

Head:

Finally found some time to get back to work on this. Like to have it running this spring, and I'm sure I'll have a few motor questions. I've got other threads on other boards regarding the bike-specific issues. The motor, as near as I can tell, is a '62 1200cc 40hp. The number on the front left under the generator pad is 6419243. That sound about right to y'all?

The engine has a pair of 28PCI Solex's on it. I ordered rebuild kits from CB Performance and opened up the carbs. I started in at the accelerator pump and found this:

Had me a little worried. No gummy fuel, but for some reason it seems to have picked up a good bit of water there some time. I started in on the rest of the body and was pretty pleased with what I found. Here's a shot of the butterfly. Looks to have been replaced at some point. This bike was put away for somewhere between 10-15 years minimum, so these look like they might have been rebuilt not long before it was put away.

The bowls were actually very nice inside. Obviously replaced internals (plastic floats and such). I'll replace the needle valves again just to be on the safe side, and of course all new gaskets.

That's a sweet bike. Never seen anything like that before. I couldn't tell from the pictures, but how is it cooled (besides air)? Obviously there's no fan, but is there an oil cooler hidden somewhere? Maybe its not needed as long as you don't idle for long periods of time I guess.

Congrats on the find and the buy! Keep us updated Very Happy
