After having to clean the carbs a bunch, it turns out it was due to the liner in the tank falling apart. All the bits and rust behind the liner kept clogging up the system.

Here is what was removed with the aid of some really long pliers and patience. This was the old liner.

New Pilot Jets & Carb Clean

Posted: January 4, 2015 in 1974 Kawasaki Z1A

GOt the correct replacement pilot jets for the smoothbore carb and put them in.  When taking the carbs apart, it could be seen that the crap leftover in the tank was clogging things up, so they carbs were cleaned at the same time.  Just have to put them back on the bike and give it a test!  Here is what they looked like when taking them apart:

Exhaust mount

Posted: December 14, 2014 in 1974 Kawasaki Z1A

Since the exhaust is an aftermarket 4 into 1 Kerker, the rear of it had to have a mount created (we didn’t have any mounts if one came with it originally).  We used some angle iron, as well as a clamp on the frame.  It’s not going anywhere now!  As a bonus, a pic of me sitting on the bike as well!  It’s pretty big!

First Ride!

Posted: December 7, 2014 in 1974 Kawasaki Z1A

Put the Z1 together enough to take it for a quick ride up and down the street!  It didn’t have a front brake, so we didn’t beat on it, but it ran and shifted nicely!

The return of compression!

Posted: December 6, 2014 in 1974 Kawasaki Z1A

Compression has been restored!  All cylinders are well within normal specs now, and its even noticeable when trying to move the kick start by hand!  Can really feel the compression that way!  Had a nice drink in my CT Rockers glass to celebrate!  Best tasting Captain and Coke in a long while!


Parts fresh from Japan!

The headlight bracket has arrived, fresh from a warehouse in Japan!  It was even packed in a bunch of Japanese newspapers!

Bent valves!

Posted: November 27, 2014 in 1974 Kawasaki Z1A

Found the reason for low compression!  There were some badly bent valves.  Below are some pics of the process, and a video for comparison.  Even got a shot of the special tool we used haha!
