Should I buy 1100M parts bike for my 1100k resto?

[Mackk]

So my 1100K is resto is well on the way, and the opportunity to buy a 1100M has popped up. 

I know the nose cone and tail cowl are different but is everything else compatible? 

Any unobtanium parts I should definately grab?

Love some opinions on whether I should buy it.

Cheers

Buy it, and restore that one as well.

There's quite a few differences between the K/L and the M/N , better off with a K or L obviously. Your K looks to be in pretty good condition, any donor parts are likely to be in a worse state than yours. As has been mentioned, you could buy the M for the next project, especially if it's the right sort of price ? ! 

Parts for our bikes are pretty plentiful, so any parts you do need can be bought either new or as very good used parts as and when needed.  It's your call, but that's what I'd do . .
