Down to a frame!

Posted: January 19, 2014 in 1974 Kawasaki Z1A

Down to just the frame on this bike now.  The top triple tree also has a pinch bolt broken in it, so that will probably need a helicoil to repair from the way it looks.

Continued breakdown

Continued the breakdown of the Z1.  Got the bike pretty much all apart including the engine pulled from the frame.  Just really have to remove the front end at this point, then clean up everything nice/replace what needs replacing, then put it all back together after some fresh paint!

One of the bolts for the intake manifolds was broken in the head (what a great discovery) and it had to be repaired.  Sonny welded it up and we just have to file it down all the way and tap it.  We also removed the valves from the head today as well.

Engine tear-down

Posted: January 5, 2014 in 1974 Kawasaki Z1A

Started the engine tear-down.  Got the head and cylinders off, as well as all the side covers.  This bike had a hydraulic clutch on it, and after some investigating it seems like it works fine still so it will probably stay.  Whoever started modifying this bike absolutely butchered the wiring.  There are many places where the wires are just snipped for no reason, not hooked up, very thin gauge going into larger gauge, and all kinds of mismatched colors.  It will be a bit of a project to correct unless I find a new harness.
We also discovered that one of the bolts holding in an intake boot was broken, along with the head in that area.  It appears that someone tried to fix it at one point and just made it worse.  We will have to see if we can repair it, otherwise we may have to use another head.
