Good video buddy, I am mostly 99% confident in rebuilding these motors ,but you sometimes forget the small steps which is why this particular video definitely deserves some credit!

[@tannerjthomas]

Thanks!

[@mikehike6894]

This is the best instructional video ive ever seen on motor rebuilds. Well done sir

[@tannerjthomas]

Thanks man! I appreciate it.

[@MrJmattr3]

Yes I agree!

[@crazychad2720]

Awesome video. Thanks to this and my service manual i was able to confirm hot rods sent me a crank bearing kit with 2 right side crank bearings with the blue seal on one side when only ONE is suppose to have it. Luckily i caught that, removed the blue seal from the stator side crank bearing and dont have to find out what would have happened!!!!!

[@tannerjthomas]

Good catch!!

[@kunalkhanna985]

Nifty tool for DIY fork seal replacement. Great idea, thanks for sharing it !!!

[@stevescheuerman]

outstanding.... building a 2007 KX450 motor and will refer to this video often

[@JavonTheWrapper]

How did it go? I’m rebuilding a 08 now waiting on parts to come in @stevescheuerman

[@chasechevy8933]

Looks like if you aren't replacing the crank, you don't even have to remove it from the left case/bearing and it will slide right out and back into the right crank bearing.

[@tannerjthomas]

Yep that’s right

[@stringbender247]

You make the absolute best videos for everything KX 450 related and seeing as my son and i have 2016 and 2017 KX450s like you, you have been an absolute blessing sir. Thank you so much! Can i ask what VP you recommend or run? We dont race motocross only offroad races(amateur and recreational) Thanks in advance

[@tannerjthomas]

Thanks! Glad I can help. I run either 110 or T4. They run fine in a stock bike without having to remap.

[@MrJmattr3]

Top shelf video! Great work!

[@alexarks517]

If you put the crank in the freezer for 30 mins it slides right into the main bearing.

Que tipos de rodamientos lleva el cigüeñal ? Sirven unos c4 ?

[@cory8832]

My engine cracked on my 2017, I have bought engine case set off ebay 2nd hand but its 2016, is anything different as I thought the 2017 had more power than the 2016, the top end I have is 2017 but bottom end is 2016

[@sheldoncooper4281]

Does anything hold the oil pump gear on? Or does it just sit in place

[@ronmower3694]

[@bubbas66]

Quick question so I keep seeing the torque specs for the head bolts are 44 ft lbs and other videos they are saying 14 which doesn’t sound right lol

[@tannerjthomas]

Yeah dude you’re right head bolts are definitely 44 ft lbs lol

[@bubbas66]

[@samirghis5644]

parfait

Im rebuilding my water pump on my 2018 kx450. Wich is the same as your bike. You might know the answer to this question. What is the part # for the o-ring [B] in the inner clutch case removal section of the service manual? I have looked on the parts diagram onine but i cant find it. The service manual says i should replace the o-ring when i reinstall the inner clutch cover, wich ill have to take off to replace the water pump seals,bearings and shaft. But i cant find the part # anywhere. I have almost everything to do the job but a new o-ring. And im the type of guy i dont want to use the old one.

[@tannerjthomas]

I see the one you’re talking about. It’s that tiny o-ring on the bottom right side of the clutch hub. I remember replacing that let me see if I can find the part number for you really quick.

[@tannerjthomas]

Give this schematic a look. Find 92055. The O-ring (B) in the service manual is actually the o-ring on the oil pump. Let me know if that’s what you were looking for or if it’s a different one.

[@mrmotocross6819]

@@tannerjthomas yea thats it thanks bro.

[@tannerjthomas]

You bet man

[@ricardomayou7641]

So the 2015 model is different?

[@tannerjthomas]

It will be similar but have slight differences. The manufacturer usually runs a base model with minor changes for 3-5 years so in this case 2016-2018 then they usually do some big changes to start a new 3-5 year cycle. All of the big stuff remains mostly the same though.
