35:08 Because new parts form ebay are chinnese crap, so used parts are better if you rebuild them, that's why used original parts are more expensive.

muito bom trabalho eu sou do Brasil acompanho vc

Im a true believer in "use what ya got" ✌️

19:39 ETV is electronic throttle valve. It’s a ride by a wire motorcycle so that is definitely important. Nice job on the fab fuel tank!

Dude your lathe skills are sick. You make it look so easy and i'm struggling to turn and bore 😆

How are you going to be able to get the c clamps in?

Starter fluid would help to see if she runs for a second

put the volume of the music up please !

Car Engine have 400rpm during cranking On starter motor. Your reverse will be way to fast 😊

Best you tube channel ever and Chris seems amazing person 👍 Greetings from Hellas 🇬🇷

Dude, I’m watching and enjoying this video. Is it just me or are you totally channeling a young Christian Slater?

Great work Chris! I'm always just blown away by your design and fabrication skills. Honestly, you're using skills that all engineers should have. Heck, with just a few math classes you should have an Engineering degree! Love the build and watching your fabrication work, and I can't wait to see the results!

22:40 - I think you can use some SikaFlex stuff for that. They make some really good cold welding glue you may use in your project. 😉

Hi, I am sorry, I don't understand how you will install the c-clips after

Isn't having that bun like that going to cause a vibration for out of balance

26:00 You should consider using green penetrating locktite instead of red for things like this.

Hmm... the diff case will also be spinning, isn't the oil going to hold to the outer casing due to centrifugal forces? Think washing machine! The fill port will create resistance on the oil as it spins and will most likely cause a rotational imbalance and probably destroy the LSD.

Its indeed nice and fancy!!

Man I hope you’re going to balance this thing

ROCKAUTO has the wheel hubs for40 a piece brand new

I think that new parts on Ebay are generally cheaper than used, because they are likely Chinese knockoffs and the used are original manufacturer (Japan). Thanks for the vids! 👍

Suggestion: Small square of aluminum on the oil housing with a 3/8” flush pipe plug would be much more tidy way to fill it ! Some bearings mount loctite should stop oil from weeping past the slip fit bearings. Having snap rings on the bearings should make it easy to remove them with loctite on them.

If you're looking for parts, Rock auto is a great look-up and they have good pictures of most of the parts. Even if you order elsewhere, it's a good catalog. Looking forward to see how this build goes.

Used automotive parts are typically more expensive due to being OEM parts. No different than autozone being cheaper than the dealership for most parts. Plus RX7 parts will pull a premium, especially any OEM parts.

Why didn't you just start with a center section from a independent suspension like a bmw or a ford 8.8 ?

Pipe threads, man. That's what they're for 😉. A little teflon tape and two pipe-threaded plugs, and those two holes on the back of the diff would probably never lose a drop of oil.

To keep impurities out of your welds. Try using a heat gun to heat it up instead of map gas. You can also use dish soap and water to clean it. Just make sure you rinse and dry good before you weld it.

Wow, that's a lot of work!

You have to send a piece of aluminum where you're going to weld

you must give 2 side oil drain bolt for counter balance

Hi Chris may 2025 give you unlimited ideas and success in creating them mate! Have a look at radius cutting tools for the lathe for projects like the spacer weld, it would have cleaned up the weld nicely leaving a tidy finish Also look for thread cutting tools from McMaster-Carr both these tools should be available their (even though I'm in the wilds of Western Australia I have heard of them😁. Also watching channels like Abomb79, and Keith Rucker you Lear a lot) You have come a long way Chris since the early days, so proud of you! Tony from Rural Western Australia 🇦🇺🦘

I am just wondering if this is gonna be able to handle the torque?

Good idea for vent was screaming at screen. How are you venting it.

I'm loving this build so far, the novelty is rare nowadays on KZbin, and you are doing something different. I love your content.

Keep it up bro your builds just keep getting better you and grind hard are both awsome channels you never let this old man down❤❤❤

Works of art man

I think that this might leak from the carrier bearings toward the center section. It looks like the carriers are only sealed on the outside. You likely need to add an oil seal in front of the bearing (toward the diff)... Always great videos.

Damn that's one cool bike but the video editing is even cooler. Good job on your production.

6:57 why not just use a big socket to tap it in instead of all crooked

All you had to do was seal the diff. Cut a gear that meshes with the starter and run that to a jackshaft, that you already needed to get engine alignment correct. You could have easily adjusted the gearing for reverse too and left all that un needed wieght out of it.

If you ever do this again there are some fwd lsd s you can buy from.the 90s that are sealed and smaller .which means you could save a lot of fab time and crown wheel un bolts so spoket can bot strate on . Nice work tho mate hat off to ya

red threadlocker is not adhesive, you need whats called retaining compound for that

Definitely not the only one. Exactly what I was thinking when you said birthday cake. Weird!

Used to watch your channel for the cool buggies you build, now as well as that i watch it for your awesome engineering skills.

mint

just wondering for the holes in the centre hub and the oil can would threading them and use grub screws work instead of machining parts to fit. i would think a threaded lock tight screw would work ok for this application. your design is fine im just inquisitive as to making it a bit easier for us non geniuses. no bad vibes intended to me you are a genius the things that poor out of your mind boggles me great vid thanks

The reason new is cheaper is because they're cheap parts. Used are genuine and far better. But as you said, for your application they'll be fine.

Nice build, have you considered a counter weight opposite of that oil bung?

Can't help but think a pair of Welch plugs would have sealed up that diff perfectly.
