- In this video we take a look at the cylinder block of the Police 1000 Kawasaki motorcycle. Check the bore diameters, evaluate the piston to bore clearances and more! Check out the video on the head work which is separate from this video.

Do what you gotta /need to do. Enjoyed the video Tom, RIDE SAFE OUT THERE!
Tenho uma aqui no Brasil, ela é sensacional a kz 1000 police , parabens por manter essa joia viva
I agree....do what is sensible given the overall condition of the bike. Then run it. Enjoy it. It'll be fine. Nobody is taking the bike to a race next weekend.
The crank brgs on this engine have been known to go 500000miles transmissions r well over built on these as well so u might b gd just doing what u r. Best of luck
5.5.23. Jugs……you said Juggs!….. I was waiting for you to say that 😮
be good enough for one of them,noise if not the chain output shaft main bearing common if chains over tightened.i agree that not worth putting the money in, it will be fine
Did the bike burn any oil in its original cobdition, before you replaced the rings?
I think you made the correct decision on the block with out knowing the condition of the bottom end, I was wondering if you checked the cam chain for stretch? Curious if it was still in spec.
I have not, as of yet but I will. I've actually never found one out of spec, but then again, the measuring methodology of a certain distance over a specific number of links, is subjective. Cheers.
Ring tension is a very important spec that almost no one has a spec on or can measure.
Rings are springs, and springs exposed to heat lose their tension.
It seems probable that the KZ1000P has been rebuild, and maybe with "trade" parts. That 5 thou piston/cylinder clearance will be a problem in my estimation. But perhaps worth a try.
It's actually just under four thou, I am correcting that huge clearance on #3 with a new piston which is 2 thou larger. That brings the clearance on all four cylinders to about .0013-.0015 over maximum. The standard being .0016 to .0026. These are about .0035-.004 now, plus or minus a tenth or two. Sucks, yea, but is what it is. All four cylinders are nearly exactly the same size, within tenths give or take. #3 piston was more aggressively worn than the other three. I agree, I don't like it either, but I have rebuilt others with just as bad clearance issues, where the budget from the customer wouldn't allow a bore and oversize piston/rings. The XS1100 was that way. I looked at my spreadsheet on those numbers and for some reason, I forgot to document the piston OD's and clearance, but I do recall the size after mic up and they were small as well. We had to leave it that way with new rings. Thing runs great so far at least. I spoke to the owner not too long ago about it.
I also agree, this top-end has likely been done once before. That base gasket situation is revealing. The only way a base gasket would come off that easy on a 20 year-old engine is if the gasket isn't 20 years old; and it has been replaced at some point.
I hate not doing it "right" like to the letter and boring/going oversized, but again, cannot justify the cost for what it is and what it will be. Cheers.
