Solid video. Thanks. Gotta check the valves on my 22. Ran a no toil pre-oiled filter and it wasn't oiled good enough. Sucked some dirt. Not happy!

[@highlandcycles]

Bummer

[@stepheno.2730]

Plenty of great information. Much appreciated. I just bought a new 2022 KX450x and there’s not a bunch of good info yet. Subbed

[@highlandcycles]

Awesome! Thanks

[@Mrmacgram]

I need to do mine on my 2010 fires right up go ride it get it hot wont start again! im hoping adjusting my valves will fix this issue! Love the vids Got my subscribe!! 🤘

[@highlandcycles]

Thanks so much.

[@sevensi62]

I know this video is older, how many sizes down. My bike is that tight on my left intake valve. So the shim I pulled do you go down say it's 2.8 to a 2.75 or 2.7? Thanks

[@highlandcycles]

I’d go 4 or 5 down

[@chdebolt]

What tool do you use for removing the crankcase and oil filler covers? I need one of those.

[@highlandcycles]

Motion pro part number is 08-0087

[@farmerjoe1114]

Sub’d! Great channel. Was looking at Kx450 vids to decide wether I want to trade my ol’ RM250 on a 2018 kx450. Love all the strokes, but think I’ll stick with 2 fer now. Cheers!

[@highlandcycles]

Thanks

[@evanmiller1642]

The current generation kx450 is a solid platform 19-23. I wouldnt get to excited over a 18 unless you really want air forks. The kx450 just does it all itl even eat up morgans new fuel injected 300 for dinner chew it up and spit it out on the knareley rocks. ;)

[@eli9494]

How many hours should this be done. I have a 2020 kx450f, it just hit 60 hours

[@highlandcycles]

Now. I try to get people to do it every 40 hrs or so

[@bobriley000444]

So you put the feeler gauge between the cam lobe and the finger? NOT between the finger and shim?

[@highlandcycles]

Yes

[@highlandcycles]

But either would work

[@jackkilleen4875]

Do you have a instructional video on replacing the valves & piston on a 4 stroke?

[@jordanchavez1953]

When you torque the cam caps do you follow the numbers on the caps? Just curious what torque patter?

[@highlandcycles]

Yes, sometimes. I mainly make sure I do a crisscross pattern

[@jordanchavez1953]

Also just curious do you have a video on hot to set timing on the cams if you take the cams out?

[@alldayride75]

Thanks fer the info.. 2019 one bad filter , almost shot.! damn that sucks. Bought a 94 xr 80 ., was missing the filter, found it in the the carb.! That was my first carb disassembly lol still starts first kick, but it is weak

[@highlandcycles]

Probably need a top end.

[@yesalli]

@@highlandcyclesWill look into it, I would surely pay to keep it tip top or upgrade the power a bit. It's pretty slick, original seat /plastic and monster stock fuel tank.. Pretty sure it was the original filter as well

[@richardhartley7094]

You do that job quicker than I can...I guess doing it every day helps fiddly job still😀👍

[@highlandcycles]

Hahaha, I do it for a living after all

Thanks for sharing, very helpful

[@highlandcycles]

Awesome

[@evanmiller1642]

Does cam chain tensioner spring push tensioner out when tensioner is removed. Ive just removed mine and done valves am worried that chain is now to tight. Great vid by the way made adjusting my valves easy. Just unsure on cam chain tension. Does tensioner need reset? Thank you

[@highlandcycles]

Yes you need to reset the tensioner.

[@evanmiller1642]

Ok thank you.

[@evanmiller1642]

The tensioner Hits the sensor on throttle body was going to pull it all the way out to see how the dang thing works. Itl come to me in my sleep lol Thank you again

[@evanmiller1642]

Also curious how many hours on this 19 at time of vid. Mines a 22 with just over 100hours. Both intakes were tight exhaust still good

[@Blocanbentlyyahu]

My bike died when I was riding. And I tried starting it and it took multiple kicks when usually it starts first kick it wouldn’t idle and shut off when I hit the gas normally the bike do you think this is my valves I’ve never adjusted them and I have a lot of hours on it

[@juliandp1768]

Wich brand has de best valve train?

[@highlandcycles]

KTM and Yamaha

[@kellylargent2634]

A year ago I never would have tried this on my own. You have really made me good with most stuff so thanks again for all you information.

Hey bud. Im saying hello from Newfoundland. Just thought you may like to know.... it was Allan Doyle's birthday. Yesterday I believe.

[@diegokosloski2944]

help! kxf450 2008. I need to adjust the superior command (right point), we don't have any parameter. I'm from Brazil, I haven't found any material that can help. ajuda! kxf450 2008. Preciso ajustar o comando superior( acertar ponto), não temos nenhum parâmetro. Sou do Brasil, não achei nenhum material que possa ajudar.

[@highlandcycles]

I don’t understand exactly.

[@diegokosloski2944]

@@highlandcycles My bike is a KXF450 year 2008, it is having problems starting, we noticed that there is apparently a difference in the adjustment of the bike's point, more precisely in the valve control. My question and my request for help, is if you have any video or something that shows any marking of where the correct alignment of the cam chain gears with the command would be, everything indicates that the gear rotated on the shaft and left the correct position, but I don't have any parameter to know if this happened, I'm researching to inform myself of possible solutions my english is null, via google translate the message above

[@HeAdChEeSe1983]

Great video. Why do all of my local mechanics have an attitude?

[@highlandcycles]

No idea. Sorry though.

[@bikelifeantvlogs6945]

What are the valve specs ?

[@highlandcycles]

.004”-.006” intake and .006”-.008” exhaust

[@evanmiller1642]

These specs are better than kawasaki specs in my opinion 0031 I think is to tight on intake side 0047 is maxish. Going off memory.

[@danehauser8675]

Great video. But they must have changed the valve specs on the newer ones as the book says .0031-.0047 intake, and .0055-.0071 exhaust. My 19hr 2023 KX450 has problems starting when hot and before assuming it was the common fuel pump issues, I wanted to check the valves and am at .004 intake and .006+ exhaust. Based on your specs, I figured I was at the bottom of the specs and was going to change all of them but it looks like I'm above midway per the KX manual. Good news is I don't need to adjust the valves but bad news is I must have one of the crappy fuel pumps, even though Kawi says mine isn't part of the recall. Anyway, if anyone else runs into this, the valve specs are lower than he mentions in the video. Still a great video though so thanks!

[@Алек-э7ж]

Привет, это не маленькие зазоры? 006, 008

[@rayv882]

Wow how about just sticking with a good old 2 stroke?

[@highlandcycles]

Hahaha. That’s what I do.

[@selcosucks]

what happened to your thumb?

[@highlandcycles]

Hahaha long story but basically a huge crash

I don't own a Kawasaki 4 stroke. But I feel sorry for those who do.
