I have been a bit intimidated by the thought of opening the bottom end of my 34k mile [running when parked] KZ750, but after reading this thread... OMG! That misalignment on the oil hole at the bearing is unbelievable. Anyone who assembled it that way should have all of their tools taken away - permanently!!!

I'm enjoying this thread. Thanks for all the photos (I love photos) and sorry for the headaches you have had to deal with.

I was lucky when rebuilding my 750 in that a member here had a spare engine he wanted gone for cheap so that was a nice part doner. Even if you only use a few random bits it will pay you back for the purchase.

Good luck and keep going...B)

No problem on the photo's, Ed. I mainly take pics for reference on my laptop or phone Or for ads if it needs to be sold, (trans ) and to have a reference as to how things were originally assembled before / as I scatter EVERYTHING. I am cleaning as I go. That bearing glitter is everywhere, and all it will take is one chunk lodged in the repaired engine somewhere to shell it out again. I am trying to keep my little workshop free of loose debris. while cleaning out chunks of bearing material glitter from both engines. I am cleaning everything as I disassemble things.

This is the clutch basket and 6 speed trans. There are 6 good pistons laying on the bench (taken yesterday) 3 good rods .The starter clutch is laying next to the alternator shaft.


I hit the cylinders with my craftsman 3 stone hone. Very light de-glazing. I don't plan on buying pistons or boring anything. This is the economy build. The pistons feel good sliding in their holes. My instructor in college was all about knurling pistons to make them fit worn engine bores. This piston is too short to knurl. The bores look good with no noticeable ring wear at the top or the bottom. I do not want to remove any more metal. These sleeves look good, and the pistons good also. I've seen some screwed up engine bores run great. These holes look as good as >any< running engine has.

There was a time when the top ring ridge was so deep that you could not beat the pistons out of a ford motor. Everyone remembers the crank type ring ridge cutters? LOL



The donor engine has a broken sleeve in hole #3. The starter clutch is behind the broken sleeve.



I do want to get the original crank out to see how bad it is. It would be nice to find a local shop that can fix the cranks, but it seems that the nitriding is somewhat special.

WTF? All of my pics are GONE! So much for sharing. :( I hear the site got hit again by hackers. Don't ask me how I really feel about hackers and scammers. Ransomware is the latest rage for bugger eating basement dweller a**wipes.

Anyway, on with the update..

This motor either has stuff literally falling apart, OR bolts that will not come off without breaking something. I am having trouble getting the counter shaft sprocket nut off so I can disassemble the old engine. . First I tried to hold the sprocket with some 630 chain, not enough to put serious torque on so, it slipped when I added a cheater bar and some heat. Next, I moved the zx to the shed door and sat the engine behind it to try to hold the sprocket with the #50 chain that is on the bike. The largest bolt I can get through the #50 chain rollers is a 1/4" X 20 bolt with the threads ground off on 2 opposite sides to make it narrower. 1 bolt snapped with torque applied. All-thread is marginal at best, so I will buy some grade 5, 1/4" X 20 bolts alter today and try doubling and tripling up on the !/4" bolts until I get that nut off. hopefully without destroying it.

The site crashed twice in the last month when it hit 100 Gigs in size, our upper limit. Since then I'd noticed that at least one of my posts had lost it's attachments. At the time I never made any connection and actually I'm not certain there is. In the last two days I've realized that the problem is more wide spread . I know that many of your posts are plagued with "Attachment not found" messages.
Anita and I are working on it. Actually she's doing the work and I'm looking over her virtual shoulder. One thing I do know is that the attachments are not lost, they're just not properly attached for the time being. We will find them and if I have to do it one picture at a time I will put them all where they belong.
The issue with the upper limit has been solved and the problem is hopefully behind us. Except for the clean up, that is.
Thanks for your patience.

I hope Anita can figure out the attachments. A LOT of them are gone. It does bring into question posting more pics, only for them to all go >POOF!. :woohoo:

Anywayyyyy... Here's today's update..

I finally got the counter-shaft sprocket nut off of the original engine so disassembly can resume. I ended up removing the uni-strut shock and swing arm assembly to remove the chain so that I could use the chain to hold the sprocket for removal. My 2 wheeler had to replicate the frame to hold the engine steady enough to get the nut off.


My Craftsman 1/2: impact wrench didn't seem to have enough oooomph to remove the nut until I went and bought some (grade 8) 1/4" bolts to hold the chain together solid enough that the impact had something solid to hammer on. I let my compressor charge fully then shut off, shot WD into the impact air hose fitting until it was spitting oil out of the exhaust, then as the oil was spitting from the impact wrench exhaust port.. The nut zinged right off! (after bolting it solid). ZING!.. done deal. Yipee! :)


In getting the counter shaft sprocket off, I removed the swing-arm to get the chain off.. THEN, while I am cleaning it all up I notice the chain has a clip type master link so the swing-arm removal was not necessary. I did clean up all of the suspension hardware and reassembled it all so I could park the roller back in the carport. Not a total loss, All of those dirty, rusty parts needed some attention anyway.


Now I can resume disassembly. I am also having trouble getting the timing plate bolt off too. I am not certain if it is a LH thread or not, and have not found it in the service manual so far. The part description does not mention LH threads so I am assuming it is standard RH threads and just stuck hard. The sprocket nut is RH threads.



Painting / cleaning the shock linkage. The little 250 watt heater aids in paint drying on chilly days while keeping the shed at somewhat tolerable temps in the winter.


I bled the rear caliper mainly to flush some fresh fluid through the rear brake hydraulics. Fast bikes (and cars) need good brakes. The Metzler rear tire looks almost new, not so much for the front tire. :)

I was just looking through this thread. All of my attachment pics are not there. poof. From the first post up until Nov 27th ? This so much retracts from the "ease of use by illustrations" designation. :)
Nothing much new to update.

This is the "dragger" Zx1100 in question. I picked this up off the garage floor and shoved it into my van.


If there is anything I can do to help with the attachment issue, let me know bill.

Yes, I have a folder on my notebook with all of the pic files of the bike. It also contains the pdf manuals that sorrocco emailed me for this 96 GPZ. I need the ability to edit my posts to try to repair the posts. Bill has been in touch via private email. This is a major crash affecting the site's informational value. As often said, a picture is worth a thousand words.

I am preparing to disassemble the original engine case. No holes, and the rod is just loose, not through the side. Hopefully this crank can be fixed / saved on the cheap. :-)

It looks like after uploading all of the missing attachment files to bill's google cloud folder, he and Anita have been clicking their fingers to the bone. (thanks Bill!) They restored no less than 50 missing attachments to my dead GPZ thread. To tell the truth, it is quite disheartening to find all of the pics missing. Kudo's to the KzR staffers!

Sooo.. I hope it's safe to continue to document my project with pics. And to tell the truth, the encouragement and comments is helpful in sorting out this basket case. I also listed the 6 speed for sale on kzr and on STL CL, along with on the zrxoa web site. I need to sell of some spares to finance the crankshaft repair. The zrxoa web site is a whole new ball game as far as posting pics., so I abandoned the pics only to ad a link to my CL ad.

My CL ad: stlouis.craigslist.org/mpo/7032729922.html

I finally disassembled the original engine that does >not< have custom ventilation. The bearings look worse than the parts donor engine. Also the same misalignment of the #3 main bearing insert. At least KHI was consistent. I can't believe QC let this slide! This whole lube oil system is a complicated mess!


The big end of the rod is still intact, but I am willing to bet is is wayyyy out of tolerance.


I tried to number stamp these rods, but that is some hard metal. I think I ruined my number stamps trying to number these rods.


The crank looks mucho better, yet still about .015"-.020" smaller (1.395") than the other 3 rod journals. (1.416") using my veneer calipers for measurements.

KZR is heavy on the pics. That's one of the best features of this site. To keep this from happening again Bill is looking into more space and how much it will cost. That's why the donations are so important.
