My first engine rebuild on a 1980 KZ1000 LTD

- Oh, the usual... I bowl, I drive around...
So far, I was able to pull the engine out of the frame, and I started tearing it down, There is ALOT of carbon build up in the engine, I have been cleaning it out with some engine cleaner spray and a toothbrush, but it is slow going.
I am a firm believer that if you are going to do something, do it right. That in mind, I want to replace as many parts that see wear as possible, I don't really know where to start on ordering parts, I was hoping there was a engine rebuild kit that I could buy and would have everything I need in it, but i haven't been able to find one. Anyone know of a kit that out there, or what parts I should replace? I'm also not opposed to doing some mild performance upgrades on this either. any advice is appreciated

Do yourself the best favor and download/purchase an oem service manual, as well as a clymer manual. Both are extremely helpful step by step books of gold for newbies.
With the instructions included in these books, you will know exactly what to inspect, replace, restore, etc. and also exactly what tools to acquire.
Best of luck!

once you get the parts reasonably clean take your pistons and cylinder to somebody with the right tools to measure the bores and pistons to see if theyre close enough to spec for a re-ring job,or if its going to need a bore job and new pistons.
if youre going to rebuild it you might as well go ahead and tell yourself youre going to replace the cam chain and guides/rollers etc,that stuff gets deep into the motor and its no fun to do twice.
good news is these motors have a pretty stout bottem end that generally doesnt need much more than a good cleaning and inspection

It is just a bunch of bells and whistles on one level. But screw one up and the rest will wait 'til you get yourself out of a bind.

as you can see, its seen better days.
most of the rubber on the cam chain guides and sprockets are cracking off or very worn
The cams have some wear on the corners. particularly on cylinder one exhaust and intake. I need to go pick up a micrometer so I can start measuring the tolerances on them.
I took the cylinder off and tried to remove the pistons. I got the circlips out but the wrist pin doesn't want to come out. The manual said to try heating up with a torch, that didn't work either, it also has a diagram for a home made puller. I'm gonna try and make it today and see if i can get those pins out.
I started to take apart the head, but the first thing it says to do in the manual is use your valve spring compressor tool. I checked on Z1 and its $190! Is there anyway to remove the valves without this tool?

Is there a way to remove the valves without having to buy the valve spring compressor tool? Id rather not drop $190 on it.
You can always take it to a engine shop... they charge a few bucks per valves (mine is around 4$)

A diy tool is relatively easy to make from a large C-clamp, plus a fitting made of pipe (steel, aluminum or PVC), or an old wrench socket (you do the sculpture).
Here's a KZr thread with some detailed info about this diy tool.
