Kawasaki Z900RS Servicing.

Doing a regular service to the Kawasaki Z900RS. I replaced the air filter, oil filter, spark plugs and did an oil change.

[@jaygdav]

Oil Filter 13 Ft Lbs. use thin layer of oil on rubber gasket of filter. Drain Bolt 21 Ft Lbs. use new crush washer. Recheck oil level after starting as oil filter is empty. Never check oil on pit or center stand. (Note: Oil filter hand or just beyond hand tight and drain bolt snugged up works just fine) BTW-excellent video!!

[@sjk8273]

Undoubtedly one of ther best maintenance videos out there for this bike. Thanks!

[@DerekHerbst747]

Those are kind words. I only addressed the 4 main aspects: air filter, oil filter, plugs and oil. I'll be making a follow up video for the other inspection and adjustment points to cover on a regular inspection service

Love that flat green colour. Sadly we don't get it here in Canada.

[@Peter760]

Thanks for sharing, whilst I did my own oil change recently. I now know the next level, getting under that fuel tank.

[@HORNET6]

Perhaps it would’ve been a good idea to wash the bike especially around the oil filter. Very useful video 👍

[@daveherbst9182]

Hi Derek , a really great service aid clip you made here . Regards

[@Maverik2408]

Bel lavoro grazie della condivisione! Domattina cambierò l’olio e il filtro olio. Sono a 10.500km. Filtro aria e candele aspetterò almeno 20.000/25.000 km ma lo farò fare in officina: troppo complesso! Bravo 👍

[@griparian]

Thanks for making this video. I noticed that at 16.08 you can see a scrubbing point on the black pipe you are holding, which could become a hole at some stage. Not sure if you should be concerned, but at least you can keep an eye on it. Cheers

[@DerekHerbst747]

Thanks for pointing it out. You have some eagle eyes! I'll check on that in the morning.

[@billbright1755]

I’d put a clean cloth over those intakes while working to avoid any possible foreign object contamination into engine. Also very careful of open spark plug holes.🕳️🕳️🕳️🕳️

It's a bit more complicated than my Kawasaki W650 very good video of the Kawasaki 900😊.

[@mrcintheuk4641]

Very interesting. 👍👍. At under 10,000 miles that's quite early to change spark plugs and air filter. To be honest, that air filter didn't look bad, just surface dirt but when you flipped through the filter the inner paper looked clean. The electrodes on even the new spark plugs looked very thin. 🤷🏼‍♂️. Anyway, better safe than sorry.

[@billbright1755]

Basically if she’s running well in clean type roads not dusty off road you can go without air filter and plug change. Oil is super easy change out and well worth doing realistically once per year with top quality synthetic 10-40 oil and filter. Same with glykol ~ wasser coolant.

[@DerekHerbst747]

Agreed, oil change is vital. However I prefer to do the full service.

[@seabee12333]

you must have a lot of miles on your Z to have worn the spark plugs like that

Great motorcycle I just bought 2019 model “cafe” tastefully modified

[@DerekHerbst747]

@@JeffreyEiler it is indeed a great motorcycle. I bought it without ever having ridden one. I watched a few KZbin reviews and was persuaded that it's a great bike. I wasn't disappointed!

[@kevinlindberg2220]

Whew! I think I'll just bring it to the dealer for maintenance.

[@flatcapcaferacer]

Nicely done!

[@creed426]

Hi, Beautiful bike! Great maintenance,I hope you don’t mind me asking a few questions. Did you have the chance to see the Z900 Special Edition? If so, what did you think of it? Thank you.

[@DerekHerbst747]

@@creed426 I have seen it but haven't ridden it. If it's better than the standard bike then it must be really good because I have very little negative to say about mine.

[@Ringer1982]

Hi, thank you for sharing this. Does your bike have the standard air/fuel tuning or did you remap the ECU? 5000 km ago I did the fuel remap and now I'm curious to see how different is the colouring of my spark plugs compared to the stock tuning.

[@DerekHerbst747]

The bike is totally standard.

[@vincentdavidson755]

Run your moter to warm up oil before you change it

[@vincentdavidson755]

I always used the 90 ° weight gear oil on my chain it pentrates the rollers and stays on never use grease 🧝⚡🏝️

[@chrisb5986]

Nobody called out plugs at 15k? Insane.

[@anggell35]

Very nice job ! Question: what was the torque for the spark plugs, oil filter and drain bolt ? Thanks in advance!

[@DerekHerbst747]

I have always set them all firmly hand tight. I honestly don't know the torque values.

[@anggell35]

Hey Derek, one more question: did you disconnect the battery before removing the spark plugs? Thanks in advance!

[@DerekHerbst747]

@@anggell35 no I left it connected. Just turn off the bike and remove the key.

You guys don’t wash the bike before you work on it ?

[@Russxm]

When you undo the fuel line under the tank with the red clip does fuel come out of the tank?

[@DerekHerbst747]

Not even a drop

[@robsonenduro3316]

in only 15k km there is absolutely no sense to check or replace spark plugs as well as that air filter. You could do it in 50k km but modern iridium plugs lasts till, 100k km easily.

[@DerekHerbst747]

Service manual says you are wrong. Every 12000km equals plugs change. Every 4000km is air filter change.

[@robsonenduro3316]

@@DerekHerbst747 manual is wrong. Read spark plugs specification. If you want to waste money go head.

Quite the ordeal getting to air filter & plugs..not user friendly at all.

[@DerekHerbst747]

Like many jobs, having the right tools is key to making the task as easy as possible. I found the most difficult part was getting the spark plugs out, until I got the right adaptor.

[@auscurrymaster]

I think this is pretty much standard procedure for most modern bikes.

[@wills5482]

You should see this on a sport bike. 10x worse

[@Zedinator593]

Is it ok to gap plugs which have gone out of spec?

[@DerekHerbst747]

It can be done but NGK recommend against it due to the brittle nature of the metals used, especially the inner electrode. The old ones on my bike were also a bit pitted, which is a good sign that it's time to replace them.

[@DerekHerbst747]

These are iridium plugs, which are more likely to break when trying to bend the ground lug.

Hello Mr Herbst. I sended you a sms. I hope you have still the same number. Greetings.😊
