1100fighter

I am building a 81 Kz1100 and melding the styles of streetfighter and cafe racer. I started off with a 81kz1100 because it was cheap. Less than $500 and that included the new clutch I had to put in the bike. Here is what I started with.
I replaced the clutch, fuel lines, and oil cooler lines. After a few rides I decided the bike could greatly benefit from a newer front end (better handling and braking). I found a 06 Zx6r front end on CL for $300. It needed a front wheel and calipers but was in pretty good shape otherwise.
After doing some research I found out the best way to make the front end swap happen was make my stock stem fit in the zx6r triple tree. For this I needed to have some machine work done. So I sent my tree off to a guy I met on the kzr forum(Leon) and he machined bushings to make my stock stem fit in the newer tree.
Here you can see the bushing Leon machined.

Next I had to figure what to do for bars. I decided I didn't want clip ons so I had to make a piece so bar clamps could fit on top of my top tree.

I put the front end all together and have been riding the bike for a few weeks now. All in all it was definitely worth doing the swap. I have on order a koso all in one gauge. and am planning to add a cafe racer style tail to the bike Which will include removing the dip in the frame. Here is the bike how it is currently. I recovered my stock seat for the time being.
