wow. This is an incredibly detailed video. I've got a '09 Ninja 250R and managed to clean my carbies last year with help of the ninja forums, but I was still stressing through the whole process until the bike was zipped up and running sweet. This vid series has given me the confidence to check valve clearances and adjust if necessary. And lets face it, with this kind of detail, anyone could do it! Thanks for the fantastic footage and attention to detail!

Let me know how it works out. I love to hear feedback from people who have done the job. I don't think many people attempt it, partly because it's intimidating, but also because most riders don't put enough miles on their bikes so that a valve adjustment is necessary.

This video is EPIC!! by far the best valve adjustment video I've seen

Great documentation of the process.

Very very good in depths very good taking your time and showing us how to take off very very good thank you !

Awesome 👏👍👌

Word of advice, just cut the coolant tank loop.. It's saved me a lot of time with carb work. Also notice that I didn't say "cut it off", all you want to do is take a pair of side cutters and snip the top of it.

Interesting idea. That design certainly costs mechanics a lot of time.

I have heard that it is the same engine design (just a bit bigger) but I really have no idea. If you're planning to do a lot of work on your motorcycle, the service manual will be your best investment (unfortunately it's not cheap--around $80-100). You should also get the Clymer Manual if they make a book on the Ninja 300 (I have not checked that they do). Clymer's are about $30. Just looking at the Ninja 300 (they are really cool looking bikes and I've seen them all over the place!) I can see that most of the parts are the same as the fourth generation Ninja 250 so there are definitely a lot of similarities.

Great videos! What interval should adjust valve ? My 2016 ninja 300 has 8k miles, do you think I should follow your video and do a valve adjustment? Thanks

I don't have a ninja 300 service manual, but the interval is probably 7500 miles because it's a two-cylinder like mine. Are you the first owner? For my bike, there's a 7500 mile interval. Don't perform this job without the service manual or the Clymer Manual.

Not sure. Maybe a problem with the O2 sensors?

26:27 Regarding the ambiguity over the water drain bolt at the engine top end: The 2008 manual specifies a torque value of 52~69 inch-pounds for 6mm general fasteners. Though this is not a "general fastener" because it has a specific torque value listed, I checked and it is 6x10mm. Perhaps they got their recommendation of 52 inch-pounds from their general reference and used it as a placeholder which they forgot to update. 69 inch-pounds is as close to the median as 52 inch-pounds would be. Perhaps it's a safe middle-ground between Kawasaki's specifications and Clymer’s. At 27:05 you say that the Coolant Change text of the 2008 version of Kawasaki’s manual explicitly states 52 inch-pounds for the engine drain bolt and 87 inch-pounds for the water pump drain bolt… but I have the first edition and it does not. The Coolant Change section is on pages 2-44 and 2-45. The same torque value is listed on both pages, though 2-45 fails to state what bolt it is referring to (2-44 says “bolts”, plural). The only place I get 52 inch pounds from Basic Torque for General Fasteners (2-10) and Engine Top End (2-7).

You must have a different printing. My 2008 manual certainly does state 52 in-lbs for the engine drain bolt. I believe they constantly update the pdf version.

​@@ninja250motorcyclemaintena7 Mine also clearly states 52 inch-pounds for the engine drain bolt, but not in the text for the coolant change procedure where you say yours has it. Mine only has it on page 2-7, in the Top End section where they attempt to list all of the torque values for general maintenance. Perhaps we shouldn't rely on the 2008 manual for less ambiguity after all. :( I'm going by an original, well-used, first printing shop manual I just got in the mail a few days ago which only references the 2008 model. It seems to be the most common edition by far after scouring eBay where I literally couldn't find a newer one (like the 2011 one you also reference). The "Kawasaki Ninja 250R Service Manual" title page says "(C) 2007 Kawasaki Heavy Industries, Ltd. First Edition (1): Nov. 15, 2007 (M)" at the bottom. I even found a few accidental references to the older EX250F model: 1-9 says the front tire width is 100 (should say 110) 2-17 says to use the center stand (should say a rear stand) 2-20 references a Center Fairing Removal procedure in the Frame chapter which doesn't exist (should say Lower Fairing Removal) ...and I'm only just getting started. :) I've been using sticky-notes to mark it up and came back here to add the info and corrections you provided. That's how I realized we must have two different 2008 service manuals. Thanks!

@@ninja250motorcyclemaintena7 Well, there it is… you were referencing the 2008 EX250K Service Manual, which is the (fuel injected spec) released in some foreign markets. The first edition of that manual was written later (Feb. 2008) and has a few corrections in it, like the tire specs and references to EX250F center stand/fairings. Meanwhile, the Coolant Change section of the 2008 EX250J (carbureted spec) service manual only mentions one, singular “drain bolt” with a corresponding torque spec of 87 inch pounds. It mentions it twice and gives the torque twice but it completely ignores the engine drain bolt. Meanwhile, the torque specs listed at the beginning of the chapter were updated to include two drain bolts in the Cooling System section: Coolant Drain Bolt (Cylinder) 52 in·lb Coolant Drain Bolt (Water Pump) 87 in·lb Much better than my manual that just says “Drain Bolt 87 in·lb” forcing you to find the other under Engine Top End. It’s clear that Kawasaki noticed their error and corrected it between these two revisions. Considering your revision also says 52 inch pounds, I think Kawasaki was just defaulting to their standard minimum torque for a 6mm bolt. Still wondering where Clymer got their torque for that bolt.

I’ve got to ask you…does our oem exhaust pipe (from the head to the “slip on” muffler section) have a catalytic converter? I’m stage 2 jetted, with uni pods, and a yoshimura tsc slip on. Contemplating unitronic efi and am thinking a “full system” catless header and mid pipe would free up some ponies. Or, if it is catless from the start (usa carb’d ‘09), I’ll save my pennies. Anybody know?

Is there a difference mechanically between the 2011 and the 2008 ninja 250. I need to adjust the valves and have no clue what I'm doing. I've done the valves on a xr 250 but that is nothing like this engine. I can't find a video on 08. Just this one but it seems like there the same. Thanks for any help

KZread notified of your comment yesterday but for some reason when I clicked on it I could not find it on 2 of 5 Valve Inspection. So I could only read about a sentence and a half. Can you send it again? I did get the gist of your question. You're right. The service manual is not very specific about how to position the crankshaft. The Clymer Manual is much more detailed. Position the crankshaft at the 1T mark with the cam lobes on cylinder #1 (left cylinder) facing away from each other and measure the valve clearance for the four valves on cylinder #1. When you're done with cylinder #1, position the crankshaft at the 2T mark with the cam lobes on cylinder #2 (right cylinder) facing away from each other and measure the valve clearance on the four valves of cylinder #2. The service manual does not explain this at all.

And thank you for making this video. I'd be totally screwed without it. I did the measurements last night and the intakes were good but on two of the ex I couldn't even get the .05 (.12mm) gage to slide in. So today out comes the camshaft. Wish me luck, God knows I'll need it. I have a tendency to overlook and mess shit up lol. But not today, I hope
