Overdue maintenance | Ninja 400 

Dude, thank you for posting this! I've been looking for a spark plug video like FOREVER.

I'm at 11,300 for the mileage of my 2019 400 Ninja...I'll be doing the air filter and plugs at 12,000...I always clean the chain when dirty and respray the chain at 400 and I check the slack in the chain too...so far the bike is a terrific 'Rocketeer'...and thanks for your video, because it all looks pretty easy to do the filter and plugs. ninja on. PS: it's always good to disconnect the battery when doing any service that may require using metal tools in tight places.

Thanks bro. I have 2020 z400 and appreciate you showing me what I will be seeing.

You’re a live saver man. Still looks hard af lol but this video has really everything I could need! Thanks so much for making this.

Here in a few years when these bikes get older and more common with people doing at home maintence this is one I bet will explode in popularity lol

lovely video bro, got this in my recommended

you deserve more subs for this vid

Dude you are a legend thanks!

Super helpful man thank you.

Great video mate

Damn like father like son

how often should sparkplugs be changed?

damn those spark plugs were fried brah

careful with those aluminum cased relay not to make contact with any metal in the bike. I once used those and it kept frying my fuses and stalled my scooter. Solution: wrap it with electrical tape

Could've just washed the air filter, wait for it dry up and put new sealant spray on it.

Spark Plugs is NGK SILMAR9B9 IRIDIUM?

Is measuring the spark plug pressure with the torque wrench even needed or is it important?

I can't get that one plug undone. Not the one with the red clamp but the other one. How did you do it?

What's the part number on the led flasher bulbs you used ? Thanks

Do you fully drain your tank before removing or let the negative pressure keep the fuel in?

Good work. Subbed 4 u, too.

Wats is timr service millage?

It's much easier on an R3

OMG he showed his plate! lets hack him
