You should "BLUE" the frame. Or black oxide. If you blue the frame you can call it "The Shotgun". Maybe do a bunch of bullet stuff to it. Valve caps, handgrips, revolver style clutch, gas cap, etc.

I'm pushing 60 in a year or so, and there was no such thing as assembly lube back in my day, I assembled with gear oil, and sparingly at that. Ahhh, the days of building minibike donks under a 45w globe that was swinging in the wind. You blokes take my memories back to a different era, but the enjoyment is all the same...

[@patrickfreeman8257]

I never had a minibike or a gokart. For me it was a '66 Datsun pickup. I still have a black line in my knuckle were a gash, from a slipped wrench, got filled with grease and never washed properly. The wound eventually healed and it's not a grease tattoo

Detroit assembly lube, commonly called peanut butter, has been around for nearly 90 years. And is still arguably one of the best thread and bearing lubes ever made.

[@ni_wink84]

Assembly lube liquifies with heat, just like grease etc. then blends with the oil so it can be drained after break in, if you’re worried about thickness or globs use comp cams cam lube, it’s thinner but sticky enough to help on that first dry start , the piston pin being raised and fewer rings used because the rod length was increased, so in order to keep the same piston height and crank clearance something has to change. Same as using a long rod on a stroker V8 build , piston ends up being shorter wrist pin is a lot higher into the ring land areas needing smaller ( thinner) or less rings

[@briansantefort]

This fear is from soap based white lithium assembly lubes which are garbage to use in a performance engine. Proper assembly lubes do melt and blend with any oil.

[@ni_wink84]

@@briansantefort I’ve never seen white lithium used as assembly lubricant before, but then again I tend to research things before I do them to find out what and why it’s used as well

Don't wanna give up low end power for high end? How 'bout two carbs? One small carb and a larger on on a progressive linkage? Might make a fun (but possibly frustrating) project for the future. Two small carbs should do the trick, if one opens before the other. Figure it out so the rest of us don't have to lol ❤

[@andrewklahn7899]

I like to use engine oil for the small tilton when I'm doing a custom build or sometimes I use the assembly lube they both have their drawbacks but whatever works use it😊

[@lukesmith8547]

It's nice to see how far you guys came especially when it comes to your shop I wish I had a shop to start with I have a few projects that need to get done but sometimes it takes help instead of being kicked when you are down

[@lomsomesGarage]

Something helpful is make a cut away side cover so you can visually look at the movement when you get everything located

[@jstephenallington8431]

Ike is absolutely right. Use the assembly lube, and change the oil after first heat-up of the motor. The assembly lube will break down and mix with the motor oil very quickly as the heat lowers the viscosity of the lube.

[@kevinhildum9186]

John I can tell you've learned a lot and I want to express how much throughout the years that I've been watching you from the very beginning at your parents house tearing up the yard and them giving you a bunch of crap about that you have excelled and you're actually surprising me with your interest in creating an engine properly assembled to perform to optimum capacity!

[@matthewdrew6268]

You guys should run a little 2 stroke oil in the fuel to keep the rings lubed, the meth washes the oil off pretty good. A 200 to 1 mix makes a big difference

[@WreckedRevival]

What I use for assembly and first run/break in really depends on the application, 2 stroke assembly would be quite a bit different than 4 stroke for assembly lubes but usually go by what's commonly recommended in service manuals. May forget a few things but generally I'll use assembly lube for valvetrain (minus cam lobes/carriers), (some)Needle Bearings/wristpins. Use either motor or 2t oil for cylinder bore, rings, cam/crank journals or bearing/carriers (also pushrods when applicable). Seals, O-rings, ball-bearings, (some) needle bearings I use high temp silicone grease or either motor, trans, or 2cycle oil depending on the type of and purpose of the seal/bearing.

[@nuttyDesignAndFab]

assembly lube vs engine oil doesn't really matter for these; the lube will protect the bearing until it dissolves in the oil naturally coming to it. In a pressurized bearing assembly lube is necessary if you let it sit any after assembly.

[@46bvexrobotics65]

hey this stuff is great, but i'd rly like to see some more gocart content, (like track stuff)!

[@michaelmikesina7302]

I used Lucas oil stabilizer. Just a nice thick oil that thins out with the heat of it running

[@jasonbirch1182]

Assembly lube isnt going to "clog" the dipper hole. Its making a bunch of pressure with that dipper and on top of that as soon as there is any temperature in the motor its melting anyway.

[@WyFoster]

I've personally seen it wipe a set of bearings when someone went crazy with it. I use the oil the engine is going to run with.

[@filmgunproductions4448]

If you're worried about paint weighing too much, be sure to take a fat dump before each test ride. Nah but seriously, love your guys' content.

I wish I had documented my engine build… Briggs and Stratton 212 with a predator 212 stage 2, 2-1 ratio rockers, long throw crank, short connecting rod cupped piston dual bearing billet side cover and a torque converter.. not sure though if it will run and how it will preform

[@jamest.5001]

On certain engines I like to use assembly lube. But I especially like to use Lucas stabilizer on bearings. Like this I'd rub a drop into the bearing surfaces. Then apply a couple drops of engine oil on the bearing, especially on cam lobes if I don't have the special stuff supplied with new cams. The thick and tacky stuff in the metal kinda sealing the journal and bearing surfaces. Then a thin oil as the lubrication. On cylinders I rub in Lucas, then oil on the rings. And oil pumps I like to fill with Lucas. Because it instantly has oil pressure soon as the pump turns Even though the Lucas runs out, it is still on the surfaces. And instantly makes pressure even years later! And Lucas seems to stick on metal longer than oil to protect the metal from rust! ✌️

[@mfree80286]

9:25 Heavyweight nondetergent engine oil with a zinc additive for assembly since you have solid lifters and an aggressive cam profile.

[@williamstamper442]

Y'all aligning yourselves with Pauls karts was the best business move y'all ever made. His stuff makes big power. He is basically applying a race car program to these small engines.

If you're going to leave the frame bare, you should coat it with some sharkhide, you can rub it on so no need for sprayers, etc, thats unless you want to spray it. I use it all the time, especially on rollbars. You're not putting heavy coats of paint on it, its just a thin glaze. You can protect all kinds of raw metals with it.

[@lukecombs5242]

ThI thing about assembly lube is soon as it gets warm it thins out so it won’t clog oil passages so it’ll be fine. 🤙🏻

[@donaldburkhard7932]

Add short threaded tube to oil drain so will not drain all over motor?

[@Hurtydwarf]

Torque Test Channel recently put out a video on different torque wrench variables like extensions, oil/no oil, etc. Oiling threads drastically changes the amount of torque being applied to them, Ike says hes torquing to 25 but that real value is probably 2-3 times higher.

[@broo_sh]

Normaly you put those bolt fittings in inside of that seat and after that you put kover on are it any fapric or leathers, ( you can put those in that way also but if someone crash and seat get a hit its can tear those fittings out of that wood.

[@naiahhaian]

I used to rebuild seadoo jetski engines, i tried both engine oil and assembly lube. No difference ever nkticed, i tend to only use assembly lube if the engine isnt going to be started straight away.

[@rydplrs71]

You want a very light coat of a high ZDDP oil. You can use high zddp oil if you want for a very short break in, but after that you want a regular oil, as zddp increases friction loses. Even with that oil on assembly you do not want to soak the parts or dip them. The only reason to use assembly lube is for engines that are not getting run shortly after assembly. If it’s going to sit a month or more assembly lube will do better at staying between the surfaces.

[@adamjankowski4315]

I use castor oil for assembly lube. Works better than anything else out there

[@williamstamper442]

I make my own assembly lube. Just buy some really thick graphite grease and mix freely with your engine run-in oil of choice. That way you can get any viscosity that you want and you know it will blend nicely with the run-in oil. Edit: Oh and a bit of graphite grease mixed with a little chainsaw oil makes a very nice torque lubricant for headbolts, studs and stuff like that. Also smells real nice.
