I have the option of getting my hands on a 2000 K1200RS written off by the insurance company for free.

Motor and box and drive train in VG cond

The question I have is obvious for modifiers

Will my K100 frame take it, if not what would I need to do to swap my K100 mill out out and insert the K1200 mill / drive train etc

Many thanks to all the wise ones

AFAIK you are perfectly happy with your Be Made. I have followed your thread and commend you on it.

TAKE THE INSURANCE WRITE OFF "For free" and make it right, or your version of, you have the ability.

Simples.

This bit is not an issue. I have powder coated the frame and it is already registered with the frame number on the alloy plate that got de-riveted and re-attatched after the powder coat, which matches the number on the bell housing. I would retain the bell housing and relocate the plate as needed.

Seems our mechanics here at the bike shops are not overly fussy in this department (at least my one isn't . . lets hope he does not retire or die before me !!) ::-))
