[@marks4058]

It's definitely a decent chunk of work, somewhere between 6 and 12 hours depending on how fast you move. I recommend having the service manual handy and re-reading it as you go. Take lots of photos and label parts and locations as you remove them. Make sure you vacuum + wipe all around the head cover and frame before you open it. You also definitely need to have a torque wrench and removable threadlocker (locktite).

Fantastic video, it's going to be a lot of help: My wife's had her 2017 N1K for a year now and it's time I dug in there and got this done. I'm holding to the hope the previous owner had the first check done on time. While we got the bike from a dealer in Mississippi, there was a card under the seat with ol' Carl's number to call, which we did. He bought the N1K to replace his Concours 14 because he's a smaller guy. Oh, and he was 77 years old when he did that. Double-oh- he'd traded the N1K in on a DCT Gold Wing. At something like 80 years old. Anyway, I had to ditch my VFR800s because I couldn't keep up once she got this thing and had to get a Honda Blackbird. Fortunately, the Bird is specified for "regular" grade fuel, 87 octane here in the US, unlike the 91-93 the Ninja demands... at a dollar-plus more a gallon here. I want to fondly recall my ZX1100E and ZRX1100 with the slide-to-the-side rockers where a shim replacement takes a couple of minutes; the cams don't need to come out. A distant dream nowadays. I keep an oil can with a manual pump and a gooseneck to slather the parts going back in with engine oil. I have used assembly lube too, but in cases where things had been apart and/or suspect for a while. Incidentally, I loved the sound effects to the point they were a bit distracting. Now, on to Tab A and Slot B.

[@marks4058]

I hope I am still riding and enjoying it at 80! Speaking of 80... This particular Z1000 just ticked over 80,000 miles on the clock and I recently did the clearances. Pretty solid engines if you stay on top of the maintenance. The valves on this one finally seem to have settled in, so not scheduling checks as frequently now.

[@williamzeller294]

@@marks4058 That's what you buy a Kawasaki for- the engine. Well, and the clutch. My beloved ZX1100E (GPZ) went to 40,000 miles before the shims needed a touching up, then again at 80K. Sold it with 106K and never, ever needed to do a repair of any kind, just tires and things. It was running perfectly when I sold it, and I still can't say why I did that.

[@monnom9641]

Thanks for this video...... you helped me make my decision....... I wont let nobody play in my engine unless obvious problems. Last time i paid 600$ for a valve adjustment was on my gsx1250fa and.......engine noises appeared 1 month later....... (and the engine was runing perfectly before the adjustement)

[@marks4058]

Please get your valve clearance checked by a professional! Do not skip this important maintenance. If you do not have this done, your engine is very likely to be damaged and the repair will be very expensive. In my experience this model of engine often needs shims changed after 40 to 50,000km and Kawasaki recommend checking more frequently. If you do not have the shims checked and changed, the exhaust valves will be burned and the engine head may be damaged.

[@delasse3178]

Hi, great video, I've already watched it several times. I've been looking for an answer on whether my bike sounds off because the valves need to be done or not, but all I can find is people saying they got their bike back/back together and POST-valvejob it doesn't sound good. Over the last year or year and a half my bike has increasingly sounded hollow and just grumpy. 2012 Ninja 1000, 19.5K, has sounded grumpy since probably 15k. When I first recognized noise/running issues(certain small RPM ranges -- at speed with low throttle, or taking off from a stop). I replaced the plugs and it sounded significantly different but still weird -- honestly, probably worse. I replaced the air filter with a k+n and that had no change. I ran fuel cleaner through it and it sounded a bit better, and I haven't experienced much for 'running issues' with it since. I also took apart my fuel pump and cleaned out my fuel filter quite a bit, and that had no real impact either. At a bit of a loss, didn't really think I'd have to worry about the valves quite yet but I have lived in the city, so my miles involve traffic. Just wondering if you have any thoughts on that? should i be paranoid I might be damaging my bike? thanks for posting the vid!

[@marks4058]

Valve clearance should be done at the specified interval on this bike. Don't skip it or put it off, particularly the first clearance check, which is almost due (24k}. It's very unlikely you will hear any major change in sound. Valves just make a quiet click/tapping sound (good) If the sound goes away you have major trouble. A grumbling sound at lower RPM can be caused by a worn front sprocket and/or chain. It may sound like it's coming from the opposite side of the bike too, which can be confusing. The exhaust system will accumulate soot over time which will change the tone and volume of the exhaust sound. That is a gradual change you will experience. Also, check you are running the correct fuel octane number (RON) that the bike is tuned for. Don't go higher or lower, just use what the manual says. I have heard that people use hotter than standard spark plugs in these to help with low RPM running. Sounds like you should get an opinion from a qualified mechanic in person. I can't hear your bike so it all just guesswork.

[@delasse3178]

​@@marks4058 Appreciate the comments. I've read of normally being no necessary changes on most N1K's at the 15-16k mark, typically. Also to "skip the first check" or that "normally the valves dont need any adjustment before 2-3x the stated service interval". So, the sound is specifically with it running, not just in gear. I'm usually running 93, but here in the US even 87 octane I believe is rated at 89-90. I pretty much always run 93. Interesting thought about the exhaust system.. could be on to something there. And/or, honestly lack of any valve chatter. I am posting a video now, no worries if you are too busy to check it out but I would be curious to hear what you thought. Having done the air filter, plugs, fuel filter, run Techron thru it twice, and only being at 19.5K, I'm at a bit of a loss for sure.

[@marks4058]

@@delasse3178 Skipping clearance checks is something you could consider when you have some data from past checks to show if this particular engine is subject to much clearance creep. Some engines are remarkably stable and others are not. I did the clearance on a Daytona 675 at 90,000km and it needed no adjustment. I've always found at least one valve needing a shim change on the Z1000. Your octane numbers in the USA are a concern for me! Can you verify what the bike is tuned for? Usually these require 95RON fuel. If it hasn't been adjusted for lower octane you probably have a pinging problem that will cause engine damage. Do you know if it was sold new from a dealership in USA? Or imported second hand? Try running a tank of fuel with sufficient lead free octane booster to get the RON number to 95. If that makes it run better, you have your answer.

[@delasse3178]

@@marks4058 thanks again for the response! the manual for my bike states that it needs 90 RON, and US 87 is 89-90 RON, though I almost always run 93. I will try to boost the octane and see if that makes a difference, but the times I have run some 87 I have not noticed any noteable differences in running quality. The only thing I haven't mentioned is I noticed a minimal amount of water inside my tank lid and was perplexed, and then went to fill up one day after a rainstorm, and water was literally on the lip of the tank opening -- like 360 degrees of water around it. Ounces of it. I dried it up with paper towels and now have a rubber mat over my gas tank so that water can't get in, as I store it with a cover. Water has definitely gotten into the tank and mixed with gas, as for how much I do not know, because I don't really know how long it was happening. I bought the bike in 2020 with 6.5k miles and it was garaged until almost 2022. From my understanding, the problem would mostly be rust in stuff like the injectors, and not engine damage. I do feel like the injectors have quieted as well, unless I'm misassociating noise.

[@marks4058]

​@@delasse3178 Good to know the bike has been adjusted for lower octane. Sounds like the filler cap drain hose is blocked. There should be a drain hole in the gutter around the tank cap which drains through a hose which exits next to the front sprocket. It might be pinched, miss-routed or blocked with dirt. If you are not running E10 or some other fuel with ethanol already, you can put a couple of teaspoons of methylated spirits into each tank of fuel. That will help disperse any water which is accumulating at the bottom of the tank. Water pooling there would cause rough running, particularly at the start of a ride.

[@marks4058]

No videos on that sorry. But, if you are experiencing poor braking power that's a good place to start. Some other things to consider are: vacuum bleeding the brake system with a syringe or vacuum bleeder (the Z's can be hard to bleed if your brake fluid is thin). Sometimes you think the job is done but there's actually quite a bit of air hiding in there. You can also try more aggressive brake pads and stainless steel rotors. Those will pull you up hard but can be quite grabby. I've done that mod before but not everyone will recommend it.

hi Mark, tell me if I need to replace the timing chain, do I need to unscrew the crankshaft sprocket with the marks?

Kawasaki say that the crank case must be split to make space to remove the timing chain. The sprocket is not removed. Other people recommend splitting the chain and pulling a new chain through with the old chain then joining it. I have not replaced a timing chain on a Z1000 so I can't offer much advice, except to avoid replacing the chain until there is actually a problem like poor timing alignment.

[@viliusjonaitis3264]

How do you think if i first check a compression before do this big job ?? If its need to do valve clearance it must affecting compression also ?? So i think its easy way check first compression or how do you think .

[@marks4058]

I would check things in this order: 1) Temperature of all 4 exhaust headers is equal when running. (Use IR thermometer). 2) Check sparkplugs. Measure gap, verify all have same gap and even tan color (use feeler gauge). Verify no leak around plugs. 4) Verify no vacuum leaks between airbox and cylinder intake port. (Smoke test) 5) Test compression with compression test gauge. Check valve clearance if compression is lower on cyl 3. 6) Test coils. (Check for spark, test voltage with ignition tester). Do the easy checks first be sure of vacuum integrity and spark plugs. Testing compression is faster than checking valve clearance, but you need the compression test tools (and understand the procedure). Tools might be expensive, perhaps you prefer to spend your time instead? For me, I sleep better at night if I know the clearance is OK.

[@marks4058]

I have another though too. Are you 100% certain the balancing gauges you are using are ok and you are doing the procedure correctly? Good idea to get someone else to check your work first before investigating at complicated problem that might not exist. Could save you a lot of time.

[@marks4058]

If you have adjusted the clearance in spec but can't get the balance correct, its probably a vacuum leak somewhere. Further adjustment of the clearances won't fix that. If you are 100% certain there are no vacuum leaks and have checked the sparkplugs are installed correctly then the next step is probably a bore scope inspection of the valves and valve seats, maybe do a leakdown/compression test too.

[@marks4058]

Yes I would change them. The clearance will keep changing over time and any that are out of spec now may continue getting worse. Since these are loose (not tight) it's safe to use the engine until you can get the shims you need.

[@enriquemc]

In my opinion 0.01 and 0.02 mm are in the experimental error of measurement. And measuring at +10C is not the same that measuring at +40C (in both cases "room temperature" depending on the place). Don't touch it. The valve cleareance is just to avoid that the valves remain open when the engine is hot. That won't be your case.

[@marks4058]

The Z1000 has a compression ratio of 11.8 to 1. So you can work out the expected compression by multiplying the compression ratio by "one atmosphere" at the location where you did the test (14.7psi at sea level). Example: 14.7 * 11.8 = 173psi. Typical range for this test is 140 to 210 psi. It changes a bit depending on how fast you crank the motor over during the test. It looks like your engine has excellent compression.

[@marks4058]

@@viliusjonaitis3264 Depends how you will generate the smoke. If it's thick dense smoke and you can make a small amount, just spray around inlet manifold/throttle body and see if smoke gets sucked in anywhere (engine running at idle). If smoke is hard to control, zip tie a rubber glove over each velocity stack, one at a time and pump smoke into the velocity stack. Then look around the engine to see if smoke comes out anywhere between the velocity stack and the air intake port on the engine (test with the engine off). If smoke comes out the exhaust, you might need to crank the motor over a few degrees to get the valves closed on the cylinder you are testing. KZbin has some videos for inspiration. Search "vacuum leak smoke test".

Hello Mark, where did you get the manual from?

[@beatsmarttie5777]

Hello mark. I just measured the clearance of all the valves of my z800. Some are at the minimum of the specification (for example exhaust : 0,22-0,31 I have two at 0,22 mm). I have seen that you had that too and left it as it is. What is your advise? Would it not be better to change the shims to get it in between?

[@marks4058]

That's a tricky call when it's right on the edge of the acceptable range. Consider what your margin of error might be on the measurements, such as the size steps of the feeler guages. Eg 0.22 could be 0.21 or 0.23 if your guages go up in increments of 0.03, or if it was a particularly hot day when you measured. Another perspective is: You have it open anyway, if you have the shims you need on hand, might as well get it perfect while you are in there. Exhaust ports tend to get tighter over time so that's an argument for doing them now.

[@marks4058]

It has been a long time since I made this video so I can't recall which shim set I was using. It's possible I might not have had a suitable shim to get closer to the middle of the tolerance range.

You need to understand how the cam chain tensioner works, correct use of a torque wrench and what the "feel" is like with feeler guages. Ideal if you can have someone else show you what a "go" and a "no-go" should feel like. Take all your measurements three times and do them again if you have doubts.

@@proutproutcamenbert In practice, you will often find you are limited by both the availability of shims in small increments and your ability to measure the clearance (eg the increment of the feeler guages). So often there will only be one shim available that you can confidently say falls inside the specified range. If you do find yourself with a choice of two shims that are compatible, then yes I would choose the one that gives more clearance, particularly if you are not going to stick to the manufacturers maintenance schedule. However, don't over think it! If it's in spec, then it's in spec.

[@NEWYORKER20241]

Hello Mark, couple of questions: Would you insert a shim if you measured something around near the limit? Let's say low end is at .15 and you measured around .147 etc (using unreal numbers). Or another way of saying it's in the range of spec according to the chart but almost out of range. Secondly, would it be okay to add a smaller shim to increase gap as long as in range? Meaning going off the chart but staying in the range according to the chart

[@marks4058]

I think it's important to understand the change over time. If you know the engine and the clearances are stable, with out change between services, then perhaps I wouldn't swap the shim. If the rate of change is unknown then personally, I would change it. Particularly for an exhaust valve, which will almost always get tighter over time. It's also useful to understand what your measurement uncertainty is. If your gauges go in steps of 0.05 then your uncertainty is at least 0.05, probably 0.07.

Do the in and ex sprockets always line up at mark 1.4 for? They never line upfor me at 2.3 hope I didn't f nothing up 🤣

[@NEWYORKER20241]

Does that 2.3 mark serve a purpose in this scenario on the rotor? My sprockets like up fine at 1.4 for in----ex and in-ex but never on 2.3

[@perciousc9145]

I did mine on a concours 14, never again. If I'm keeping the bike for that long I will pay a proper mechanic to do it for me.

[@CronoCueva]

great video!, but please take care of the sound next time

[@buana345]

Did you replace spark plug gasket and/or put some sealant on it?

[@marks4058]

No, I reused the original gaskets as they were in excellent condition. I only applied sealant in the locations specified in the service manual (the cam shafts cut-outs).

[@jacrancam]

That’s a lotta work

[@חייםיצחק-י7ת]

what thread lock did you used for cam cogwheels? thanks

Marvellous

At How many miles would this be recommend? Miles or kilometers.

[@marks4058]

Kawasaki recommend doing this every 24,000 km or 15,000 miles. However, people frequently leave it much longer. This particular bike had not been checked for at least 50,000km.

[@viliusjonaitis3264]

I just been yesterday to discus for them with Kawasaki they say my milage is 19k miles and need todo this job on 29k miles , i now feeling vibration i do throttle body balance but i thing i can’t to do proper throttle body balance because i guess i need to do first shims .

这是锻造凸轮轴吗？

[@marks4058]

凸轮轴似乎是铸造后进行铣削加工的，而不是锻造的

[@Hussaiin1]

Was that ABRO Grey 999 sealant at 11:04?

[@marks4058]

Yes, if memory serves me correctly it was. That sealant performed well in this application and was easy to remove when I serviced this bike 30,000km later.

[@Hussaiin1]

@@marks4058 Good, thanks for the reply

[@Peter-un8no]

After seeing this, I think I stick with my Honda CBF1000 and NC750X.

What the spark plug type for z1000?

[@marks4058]

NGK CR9EIA-9

[@oppai1568]

@@marks4058 This is genuine like from factory?

[@marks4058]

Yes, that is the plug listed in the service manual. They last at least 60,000km and only need to be changed if they are out of spec (enlarged spark gap, not firing, damaged or eroded).

[@oppai1568]

@@marks4058 Oke thanks bro

[@spoonman73]

Haha your emojis made me lol..

[@fallenwout]

If you pay a mechanic to do this, it looks like it is cheaper to buy a new one.

[@marks4058]

It's definitely an expensive job. Probably around 8 hours work in total.

[@johnmayberry7669]

Whats the point of doing a cracking video then showing it at 200mph🤔🤔🤔🤔

[@marks4058]

It's an artistic counterpoint to all the long, drawn out, heavily narrated KZbin mechanical videos where you could go make a coffee then take a stroll around the block and not miss a thing. Also, I watch too much Jimmy Diresta.

[@nuclearchris832]

Mark S thanks for this. I will give it ago because of your video. Also I want to acknowledge all the good camera work so I can see what’s going on

[@armandblake]

I think I’ll leave this for the pro and just pay

[@billmartin126]

I think I will ride my Harley sportster more and Kawasaki Z900RS cafe less.
