R2V engine in R51/3 frame
I have found a R51/3 frame for sale. Now i am toying with the idea of building a low cost bobber. Does any of you guys know if it would be posssible to install a later Airhead engine in this frame. Maybe something like a R65 engine? Maybe cut down to clear the upper frame tube?
Also could you point me i direction to where i can buy shocks and other parts for a R51/3.
Any help/ideas are appreciated.

Maybe you should post this on the Vintage BMW Motorcycle forum......Someone just MIGHT be looking for that particular frame.

What's the VIN on the frame? There really is an "orphan list". Somebody might just be holding on to the motor for that frame.
51/3's don't really have "shocks" or "suspension". They have "dampeners" , leather seals and a big spring under the seat...
A lot of folks have stuffed modern motors in /2 frames. Dealing with that /3 frame isn't going to be quick, easy or cheap...

See if someone will trade you for a later model /2 frame. The /3 is worth more complete and the /2 gives you more options and includes a real 2 shock suspension.
Post to the Vintage BMW forum with the VIN..Collectors are always looking

Sawzall will make a nice Honda 750 fit in that frame - convert to chain drive and you will have one sweet bike!!!
Do it then my R51/3 will be worth more $$$$ - another one bits the dust
Oh wait I don't have a R51/3 - Put down the sawzall.
really the /2 frames will take a newer engine flip the /3 frame for some $$$
is there a R51/3??? what year??? Look up years 1951 telescoping front forks?? Does the frame have sidecar lugs??
Looks like any airhead engine would fit this frame with some mods of course - Wikipedia is your friend.

You can stuff a post 70 motor and trans in that frame. You will need a /3 driveshaft and rear drive as well you will need to modify the transmission output flange for a /3 driveshaft which is something that Kevin Brooks should be able to do.
