Cylinderhead for "Reserve"
31 Mar 2025 06:55
I had a black Z1R cylinder head in storage, which I took to the paint stripper the other day and got back today. The paint is almost completely gone. There are just a few small inner corners, but I can get those clean with a small rotating wire brush. I've already lapped the valves and seats. So I have a relatively good cylinder head in reserve. ( We all know: To have it is much better than to need it!)
(( I´ve given the plug threads a little kind of "cleaning cut" with the correct tap M14 x 1,25, so final job is to put on new valvestem seals, springs and valves ))

Sure, all Z1R / D1 / D2 engines were black,... but I only have 2 Z1000 with their bare aluminum engines
, ...and for these the cylinder head should be (in an emergency maybe..or if i will find an engine without head...?)

Ha, You know Clay, ..Whenever you need the balloons, they don't work...it´s a miracle...hmmm
This morn, i´ve complete the head with the fresh in-lapped valves + springs,..the valve guides have been wery well,..no action was necessary for them, thats alot of luck, and of course, it saves a few bucks also about..

We're birds of the same feather then. I've been modifying crap for years too!
. A long 3/8 socket works too, just have to cut a bit out of it to access the keepers, haha

This morning, I quickly made the 8 guide bushings for the camshaft bearings:
(The guy I bought the head from lost all 16 screws and the 8 bushings...).
(When I make such relatively thin-walled and small bushings, I always convert my lathe to a collet chuck to ensure that the roundness or dimensional accuracy of the bushings is not compromised by any "squashing" or compression!)
I used 8x1 mm precision steel tubing for this, which has exactly the same dimensions as the original bushings. It's important that the upper end of the bushings also has a fine outer radius so that the bearing blocks can be easily guided onto them!
Then I cut them to a length of 14 mm, deburred them, and they're done. Fits like a glove....
