91 K100RS motor&trans in a 85 K100 frame?

Like the title says. Will a 91 K100RS motor and Trans fit in a 85 K100 standard frame?

Thanks,
Bugs

It definitely will FIT. I have a '93 1100 engine in mine, and I'm not exactly sure of the vintage of the transmission (I know it's K11).

The problem comes with using the '85 fuel injection with the 4 valve engine. I adapted the whole Motronic system from the '93. Next problem was adapting the '85 electrical system to run the Motonic. Not a job for a beginner and you have to make compromises as to what you really want to work. I remember I gave up the clutch interlock, there may have been more, but right now I don't remember.

After some teething pains (grounds mainly) the bike is totally reliable.
