that bolt trick splitiing the cases was genius

👍

[@andrewmapes8205]

Awesome tutorial. I just bought my son a KTM 150 for racing and weve never had one, always had japanese bikes so i'm going to need to know these little differences when rebuilding.

[@UpAllNight91]

Thanks! Yeah the KTM is surely just a little different. Mainly the cylinder base gasket, getting the right one.

[@AndrewBurtonS-group]

great video thanks. I like how the split the case. Ill give it a shot

[@UpAllNight91]

Right on, Thanks!

Nice! Yeah I try to cover all the brands and models as good examples that will make good videos come through my hands.

Thats good news! Glad to hear it helped out!

Awesomeness i really enjoy these video's im getting closer on the wr300yz .

[@gordonstimmel4590]

It's just put together incorrectly on the inside so I will be splitting the cases this Saturday so excited this is not costing me any more money just time an learning how to build something Yamaha obviously never wanted to happen because they didn't want to beat ktm is what I think but my Yamaha is a Frankenstein.

[@UpAllNight91]

What year is the 300?

[@gordonstimmel4590]

It's a custom build Athena 300 it's actually a 2005 yz250

[@gordonstimmel4590]

I just got the engine an transmission out

[@gordonstimmel4590]

Probably going to figure it out Saturday why an fix it I messed up putting it together but it's all a learning process

[@AUSTIN_457]

Cheers for this. This will be helpful as i have a 2022. Ive already replaced my crank to get rid of the poo poo one that came from factory. But this will be a great reference for the future. Thanks man

[@UpAllNight91]

Yes sir! Thanks for watching!

[@oBlair65o]

What's wrong with the factory ones and what one do you switch to?

[@sethmacgillivary1281]

What bike do u have?

[@AUSTIN_457]

@oBlair65o people were blowing rods under 15 hours. That's why ktm did a CDI recall. Basically a bandaid fix. They switched manufactures for 2022 I believe and they were junk. The crank was soon replaced with a different part number

[@AUSTIN_457]

@sethmacgillivary1281 if you're replying to me, a 2022 ktm 150sx. I got a bunch of vids on my channel 🤙

[@robertcheney6753]

was wondering when you use an impact driver to tighten the clutch does the tool itself keep it from spinning and how accurate is your torque do you think? thank you I haven't used an impact driver really at all, also would an electric impact driver work the same?

[@UpAllNight91]

The way the impact hits in snaps, it keeps it from just spinning. If you get a electric impact be sure to get a good one that has at least 2 or 3 different power settings. The torque is accurate enough if you are very familiar with your tools and been doing this for years but because of this I think I may stop using the impact as much in my videos and resort to a torque wrench and locking the motor from spinning just because I know most the guys watching these don't have that kind of experience and my goal is to get them through the job with good results.

[@robertcheney6753]

10-4 thank you

[@JoshuaCussins]

How many hours where on the old crank?

[@UpAllNight91]

88 hours. Kinda young

[@76skyking]

I'm at the point where I'm trying to pull the bearing using the blind bearing puller. I'm afraid to crack the case using the tool because that bearing is really in there. I don't want to scuff up the inside area where the crankshaft spins. Have you ever cracked a case using that tool or scuffed up the inside crank area?

[@UpAllNight91]

Hello. I have never had a issue where its damaged anything using the blind bearing puller. But what you can do is heat the whole case to about 170 degrees and that should surely allow it to be pulled out easier.

[@UpAllNight91]

You can set you oven to 170 degrees, put the case in there for about 5 or 10 minutes.

[@76skyking]

I’ll try that. Thanks!

[@CZwies20]

why didnt you do the transmission bearings?

[@UpAllNight91]

Hello. At the time the bike only had about 60 hours on it and the transmission and transmission bearings where fine. We just needed to get a new crank and crank bearings in there.

What’s a lock washer

[@UpAllNight91]

A washer that provides friction or some type of folding tab that keeps the nut from coming loose.

@@UpAllNight91 when some rod bearings and main bearings last longer then other brands what’s the difference in them?

[@sethmacgillivary1281]

Like how ktm rod/main bearings normally last longer then Yamaha

[@UpAllNight91]

I think it comes down to the state of tune. And the premix ratio. If its tuned well and enough oil is used the bearing should last a good full life
