Firstly thank you for the warm welcome.  
I'm building a k100 cafe racer and need a little info. I'm looking to lift the rear end a couple of inch and was hoping some one new of a rear shock that would drop straight in. 
Maybe something from another bike.... I have a wife so have to watch what I spend.

I have just done the same thing to my k75. Put a k1100 shock in rear and is 30mm longer at lowest setting. bear in mind the main stand no longer works (was going to remove anyway) and on side stand leans a lot which I don""t mind but have heard oil is known to flow into head and sit there so smokes on start up. Havn't noticed as of yet
