1980 KZ1000 Z1R Turbo: Resto Dragster

1980 KZ1000 Z1R Turbo

This is our Z1R project. My dad and I picked this up from Ebay, summer of 2013. Barely running, kind of slapped together, and practically no documentation or known history on the bike. Trailered it back to Florida, and barely made it home before we stripped it down to nothing. Not having any intention of doing so, we found ourselves starting a restoration/build on this bike. 8 months later, we're almost back to a rolling bike. Doing all the work at home (minus powder coating/ceramic coating), all fab was done by my father and his staff in their machine shop. We will post updates as we make some progress.

Correct me if I'm wrong but I think factory Z1R-TC's only came out in '78-'79. We were lucky that the original ATP (american turbo pak) parts were used when this bike was pieced together by the previous owner. If anyone has any knowledge about this bikes previous life, please feel free to chime in. Enjoy the build.






















Sandblasted frame (Cut off center stand mounts shortly after this photo)


Sketch for the eventual custom seat




Degreeing Cams




Fully painted and ready to seal up. (Even though we ended up sandblasting and polishing most of the covers after all)


Mocked up. 1428cc ready to get mounted back in its frame.






Back from the powder coaters






This was a fun moment






Oil Cooler mounted

Mocking up/measuring for oil lines etc..


Modified oil send/return




Custom oil temp fitting


Bought this crappy attempt at an exhaust on Ebay as a template. Finished product will be tighter to the block








Getting close to final assembly.

Welcome , I Love Turbo Kaws !!!! :evil:
I will be watching very closely. From your sketch I assume you are keeping it mostly for drag racing .

Such a sweet ride! Will definitely be following this!

Where in the heck is that DRUEL icon!!! Some people don't have a clue but if it's a Z1R, it's supposed to be a turbo. Those that weren't, were mistakes!!! :laugh: :laugh: :laugh: :laugh:
I have 3 complete Z1Rs and every one of them will be turbos when I'm done.

Glad you guys are as excited about this build as we are! Stay tuned!

Im still trying to load all the pics up till the point we're at now. Check in the original post for news pics, and in the future for new updates!

Motor Assembly pics will be up tonight.

We are building this bike under the technical advice of Mike from New Age Cycles, in Opa-Locka Florida. He is our go to guy with questions or hard to find parts. All engine machining also performed at New Age Cycles. Have nothing but good things to say about that shop. Mike does great work.

To answer the previous question, this bike will be mostly for weekend fun. We might run it down the track at WPB raceway (formerly Moroso Motorsports park) to see what she can do.
