How to Make Your Go Kart Launch Harder ~ 40 Series CVT/ Torque Converter Upgrade

[@sal_e._mander5151]

A subscriber work weekend would be fun, a few subscribers bring their carts and the RBG crew can help them sort out issues. Just an idea!

[@charlespellens]

Your videos are always so informative rather than "Welp this is what I did". You, instead, show the process (even if it appears small at the end) which I appreciate. Thank you!

[@randythompson4927]

I'm working on a neighbor lady's grandson's cart. You video is very helpful. Thanks

[@terryj257]

Good clutches. I've been using the same clutch for 22 years. Just needs to be cleaned out and relubed once in a while, whenever it starts sticking. Comet says it's good to 18hp. I have it on a 23hp Briggs. The belt slips a little bit but not enough to make me get a different clutch.

[@IglesiaNuevoSemmbrador]

Hey Brother i love your blessings at the end of every episode. God bless you too.

[@meco72104]

Nice informative video. Yall need a pole barn for all the stuff outside.

[@desertdirtbikes2163]

huge fans! you inspired us to make similar content. Thanks rbg.

[@aserta]

Yeah, that bronze bushing needs to be wider. That's a major flaw and it's always going to have some level of stickage, especially once it gets worn. Needs to be at least double the current width, and it wouldn't hurt it if it was thicker too.

[@GPDIY]

This is a so relaxing and soothing sound.

[@kevinstott1317]

Awesome video showing how to do something from beginning to end. Appreciate that!!! Not to tell you your business, but you guys have families. You gotta wear helmets everytime you ride.

[@thomaspigg306]

I would love to ride the cart but my spine is already shot and this would make me worse.... but I love to see good people have fun, so Y'all keep it up, Ya hear?!

[@lightningxx]

Thanks for this video. I’ve had issues with keeping my 40 series lubed since day one but I’ve never gotten the comet graphite lube. I’ve tried PTFE, Moly, and white lithium grease and they don’t last more then a day or 2 of hard riding before they need more.

[@VladislavKulakovsky]

Tell me, will graphite grease solve the problem?

[@Clay_kn4nil]

I'm surprised no-one has given you hell about those "yalla" springs. Keep up the content brother! 🤣

I see RBG video, I click. Hope these upgrades hold up over time.

[@TeleCaster66]

There is another video out there that shows a way to open this without removing the welded nut, basically he put the welded nut in a vice and used a breaker bar with a slotted shaft welded onto it to loosen it from the inside.

[@M.TTT.]

My clutch needs servicing again, thanks for the reminder. Gonna order some heavy weights and red springs for now on stock setup, honda gx390 dingo.

[@slimyelbow]

And..did it help? I just added the red springs and it helped mine.

[@ntesla5779]

Hey red beard. Been watching for years and I’ve really enjoyed everything especially your engine build videos. A long time ago you showed how you mounted your Bauer portable band saw on a stand. I’d like to do that. Do you remember the video so I could go back and watch it again. I know it’s a long shot but figured I’d ask.

[@Skiridr22]

Nice, I learned something new today?

[@jessevangans2195]

Dutch invention. Developed in the fifties and sixties under the direction of Hub van Doorne of DAF. In 1958 Van Doorne introduced the Variomatic transmission system with belt drive.

[@TACOMASRT5]

Predator 212, governor bypassed, 24mm carb, upgraded valve springs, building for a bicycle to commute to work. Should I run a 30 series torque converter or 40 series?

[@collinklitz7434]

Apparently, from what BMI Karts says, the creeping at idle issue is because the belt is just very slightly too short.

[@sociallydistantcamper]

Im assuming this took care of the disengaging issue too ? Along with opening the idle range?

[@smallblockperformance6742]

Need more boosted projects!!

[@rcclassiccrawlers4368]

That buggy looks like a damn rough ride. May need some trail smoothers before hand

[@SportbikerNZ]

And ruin the trail for suspension go karts? No way.

[@gilbos440rt]

I was wondering if you sell or have a link to the tool you made to disassemble the 40 series pulley? Mine just did it for the first time on a 440cc 18hp Kilowatt so would you do the 2600 rpm or the 2000rpm springs on that heavy a Kart? Thanks great videos!

[@alexanderdesfosses]

FYI graphite lube is very abrasive years as a locksmith has shown me hundreds of destroyed brass lock components

[@shanehathaway2791]

Your awesome red bread

[@abrahampeshko1858]

Thanks for the video RBG and god bless

[@MrJjhemi]

Is this a better setup for a heavier rider ?

[@DJsHotRodFab]

We had the exact same thing happen to one of our 40 series drivers.

[@psychologicalsigma9917]

I heard green spring on the right hole gives u the best performance

[@jpaulie2008]

I learned something today. thank you

[@shannonrickman7620]

Would it help the ride to rubber mount the seat or maybe some lawnmower seat springs

[@shaunhuckabee5904]

I have both drivers for my built Predator 301cc and the springs inside the Comet for the rollers broke. I took them both apart to apply dry lube to the rollers and guides and I was pissed! I'd go Ebay!

[@The_Prankster]

No fury like stretching Lonnie's hat.

[@OscarMartinez-js1it]

Can you grind down the stock weights to look like the medium ones

[@davidbrannan987]

Redbeard……I was looking at the 780 set up but it’s very expensive. Can a 40 or 44 be built to handle 25-30hp?

[@DavesCoolCustomBikes]

Hey can you send me a link to your heavy duty spindle set I’d like to order a few sets 🎉thanks

[@horacioarredondo7670]

will this clutch work on a golf cart

[@MachinesWithDavid]

Hey RedBeard I’ve got a go kart I’m doing a full build on and I’m using the 440cc duromax, can I ask why didn’t change to the medium weights for that ones pulley?

[@dustinjohnson2116]

Could you send me a link or tell me how to get to the 40 series torque converter with the yellow spring already in it. That’s what I currently have now. I can’t seem to find the one on go power sports with buying the entire kit

[@lizzard7473]

Cool video thanks for making it

[@98wytebird]

Basically like running a high stall converter in transmission on your truck

[@dennisdavis6799]

So do you prefer the TQ or that 3D printed race clutch with the engagement hand lever?

[@johncorreia9041]

hey red what is that big washer you are bending oner the big jackshaft nut called?? thanks

[@AyGrom]

Hey Red Beard.....I have an Explorer with a 212 with stage 1, what do u think would be the best TC spring/weight setup? I mainly do yard riding.

[@MrSprintcat]

Thanks for the video awesome

[@TheOriginalAndysGarage]

You do not have to cut the weld on the nut, put the nut in the Vise and unscrew it from the back side, find a scrap of 1 inch keyed stock and make a breaker bar out of it you unscrew it that way

[@hightcd]

Yallow springs 👍😁

No sir. You will go through belts and eventually break the pulleys.

[@tonyestvik7969]

Question, mabye a idiotic one, if you have a 30 series pully and bakeplate, are the 40 series bakeplate the same size?.......

[@terryj257]

Those welds, on the big nut, don't need to be ground off, to take the cover off, on the genuine Comet clutch cover. I just took mine off and took it apart a minute ago, to make sure I don't give y'all B.S. info. Could use a freshening up anyway.

[@BubbaB43]

I was thinking the same thing, I've never owned a OEM Comet drive clutch but it's pretty much common sense just by knowing how the chinesium clones come apart. Spin the outer sheive while the unit is slid on the crankshaft without the retaining bolt of course lol, is that right?

[@terryj257]

@@BubbaB43 yes, that's right. The cover turns with the nut welded to it, along with all the other stuff. When you run out of threads it will pop up or off, but don't worry about it hitting you in the face, like Redbeard said. I don't know what spring is in his clutch, but mine isn't that strong.

[@lightningxx]

Yep. I just flip mine upside down with the nut In a vice and use a pipe wrench on the driver itself.

[@geogeoo876]

So do you recommen to swap red springs for yellow ones? If yes why

[@veegaveera138]

Nah he likes the "yallow" ones

[@corybrees8100]

Can you do a 23hp vanguard up grades in other words a 23hp mud buddy

[@nikoash4796]

@RedBeardsGarage you only mentioned the setup for the driver pulley..is there any steps to setup the driven pulley to match up to the driver?

[@BubbaB43]

Yes there is, idk if you've ever owned a 30 series torque converter or not but just like the 30 series the 40 series drivers have three different holes for setting the spring tention. The tightest position #3 is for straight up hill climbing, position #2 is for pretty much all terrain (this is also the factory setting, last is position #1 which is for flat ground/top speed riding. Hope this helps. Now the way I turn my 40 series that I currently run was drilling two extra holes in between the three that already existed basically giving it seven different positions. Because in my particular application I found that mine ran best between positions 2 and 3!

[@nikoash4796]

@@BubbaB43 thanks man I seen it in another video of the three holes..I'm running a polaris 250cc motor on my buggy now but it's just about shot so I'm going to go with a duramax 440 next.

[@lazzer408]

Just reminding you and all your viewers that have 40 series cannot be used in that direction properly. You're running it backwards. If you need an explanation just message me.

[@karlonadkins1579]

Please explain..

[@michaelstump6933]

Buehler? Buehler?

[@lazzer408]

Because when the engine side pulley closes, the belt moves inward. When the secondary side opens, the belt moves outwards. The spring need to face inward on the secondary. As it was designed to run. Only the 30 series TAV2 ect were designed to run with the secondary spring facing outwards. That's why it uses an asymetrical belt. Some idiot makes this wannabe TAV2 out of a 40 series and it's wrong because they don't understand that the reverse secondary spring exists incase the system turns the opposite direction, NOT so you can flip the secondary over. @@michaelstump6933
