Hey go watch red beards garages newest video. you guys should do a project with one of those

[@officialengineFAQs]

That piece is the emulsion tube of the carb. It mixes the fuel and air and comes with the new jet because it has enlarged hole sizes to work well with the larger jet. Tip: Use an in-line fuel filter.

[@NubsWithGuns]

Less hole and it is in case the bigger jet wasn't enough. Gx140 emulsion tube is what usually comes with jets.

Should run a fuel filter and install a shutoff valve. Close the valve and run the carb out of gas every time you're done with it. Ethanol free gas also helps.

I can't find out how to tighten the spring on the the pulley in between the clutch and the back chain sprocket does anybody know it's like it popped off and unsprung itself a couple times so it's making the handlebar shake vigorously when it's on sitting on idle

[@jeepcollector91]

I've had good luck with using *Sta-Bil Marine* fuel treatment. I have several carbureted engines that sit for long periods of time and have yet to have any issues with any of them as long as that fuel treatment is in the fuel left in the bowls. I only use the marine formula though and not their regular formula.

[@ExperimentalFun]

You guys really need to start adding STA-BIL Storage Fuel Stabilizer to all your gas, you are constantly gumming up your carbs

[@MrGuitarbike]

What I would recommend for that centrifugal clutch is to take it apart and cut the weight retainer spring down a bit. maybe 3-4 turns at a time, and after you cut it you can just bend the end up a bit to re-form the hook. What this will do it make it engage at a higher RPM, thus reducing the heat generated from just idleing. It will also engage higher in the torque curve which means you get more power at initial engagement. It's a bit of an art tuning the clutch right with the gearing, though.

[@richardhatt6541]

The ad before this played was for accident insurance. How appropriate.

[@terracethornhill]

Before you change the carb, try cleaning the primary jet. It's held in place by the idle speed adjustment screw. Once you take that screw out, use a flat screwdriver to gently pry the jet holder out of the top of the carb. Take a single strand of bike cable and poke it through the hole in the brass jet, don't force it. Then, with the bowl off, blow everything out. Use carb cleaner with a spray nozzle to spray into the small hole at the bottom of the jet holder hole to make sure it comes out below by the main jet.

[@nickkluger97]

You guys should use cheap round slide carbs from a pit bike, or a small dirt bike. Way more tunable and a fair bit more performance then one of those carbs.

[@thomasaitken9790]

[@watermanone7567]

The emulsion tube and the jet are paired up. The emulsion tube just pushes down from the throat of the carb and drops out after the jet is out. Just make sure you don't screw up the two tiny o-rings. Replace them if damaged. Put a drop of oil on the O-rings when reinstalling. Some have plastic emulsion tubes that get brittle, so be gentle.

[@Robertas_Grigas]

Put the 24mm mikuni replica carburetor that goopowersports sent to you on a minibike or on the China cart

[@sabrom]

"EMULSION TUBE" is the name of the gold tube you had in your hand.

[@dylanevans7498]

the biggest thing i learnt in this video is how to do a quick dismount

[@carmelpule6954]

It is an emulsion tube to froth the liquid fuel. The “froth” created by emulsion tubes improves fuel atomization. In the GL1000, both the main and secondary main fuel jets employ emulsion tubes. Keep in mind that when a bike sits unused for any length of time, these emulsion tubes can get plugged with residues. This will seriously disrupt the air-fuel mixture. Each carb may be affected differently, so the symptoms can be a bit contradictory and elusive. Generally, the lack of air will cause an over-rich condition on the affected carb(s). Depending on which holes are plugged, you can sometimes get weird, rpm-dependent problems.

[@GioGuitarDude]

IKE AND JON!!!! Dudes, the lawnmower tires they sell at Walmart 15x6.00-6 work AWESOME as replacements for these db30 mini bikes. We have 5 doodle bugs with 212 predators and torque converters, and those tires last way longer and grip way better

[@shakerattleandrollgarage7223]

"Quick dismount " 😂 that's pretty good.... they put alot of torque on those ,cool stuff👍

[@redeemedrigswheelingvideos8002]

The struggle is real bros! I use Techron complete fuel system cleaner in all my small engines before I shut them down for any time longer than 2 weeks. I also treat my gas in my gas cans with it.

[@MountainEagle77]

I have a ton of play in my brake as well, on my mega moto 80. Brand new. Have tried fixing it and can’t figure it out.

[@TheHammerChannel]

It's Called a "Emulsion Tube"- The fuel is metered through the main jet while the air is controlled through what is generally called the 'air correction jet'. Somewhere in between, the fuel and air are intermixed to form an "Emulsion" - a fine dispersant of the air inside the fuel.

[@lowlifeslides9918]

That small tube is called an "Emulsion Tube" if im not mistaken. it is the tube that sprays fuel into the carb so it is very important the jet had a proper size emulsion tube to flow all the fuel its sending.

pull the idle speed screw all the way out and pry the idle jet out and clean it and maybe even open it up a size, it will help with the of idle throttle response.

[@frankgrey4070]

here's an idea. how about building a chopper mini bike? raked front end, Springer rear, wide rear tire and a 670. you'd probably have to design and build you're own frame. could be an awesome winter project! what ya think?

[@bradfordeaton6558]

It's an emulsion tube, it controls fuel/air mixing in the main circuit and spill over point. If you don't have a flow bench go with what they sent you.

[@butchs.4239]

You guys need to find a station selling ethanol free fuel, they typically cater to boaters so I'd expect there is one somewhere near the launch ramp. As an alternative, Lowe's sells TruFuel in gallon cans. It's not cheap but it's ethanol free and has stabilizer already added. It'd save you the hassle of messing with carbs after something has sat for awhile. John's bike needs a smaller rear sprocket to go with the torque converter.

[@terraavis]

That's an impressive chimney.

[@robplotts9412]

ive been using Briggs fuel additive. It's supposedly good for 24 months gas storage if you use what they recommend you can do double the amount and increased gas storage up to 36 months I run it in all of my things and the past two years I have had no problems with my lawn mowers or weed wackers and my vehicles seem to like it.good for ethanol crap problems too.sweet mini bikes!👍👍

I also have an old go kart that I got a predator 212 for and It definitely needs a torque converter! You guys are the reason I'm gonna get one!

[@DieselBlade10]

You guys should get pit bikes. Like 125cc crf70 style bikes. They make them in manual and semi manual transmissions. They're a blast to ride

you need to swap the sprocket for a smaller one on the mini bike with the torque converter. it might prevent Wheelies.

[@logansocha2172]

Jake Brown why would you want to do that 😂

[@jakebrown5756]

It would decrease the start off torque, therefore you would not have Wheelie's. In another point it would increase the top end speed .

Thanks Jake, my mini trows me off like a dare horse. Hit my butt a few times

I believe it's called an emulsion tube. It better atomizes the fuel into the passing air for a more consistent mixture.

[@ImpenetrableSilence]

Hey Ike, your dead spot is likely because of the lack of an emulsion tube. That controls most of the fueling. I drilled my pilot jet and main jet to start and notice it was a little flat on takeoff. Got the proper jet and emulsion tube kit and now it is SNOTTY from takeoff to the top of the range.

[@ImpenetrableSilence]

I'd also like to suggest you guys buy the yellow driven spring and a blue garter spring. It will bump your takeoff SIGNIFICANTLY on all your toys while making it more manageable.

[@gianniross8962]

They sound make some type of homemade cooling system that will be interesting to watch

[@Chris-yy7qc]

You have to remove any gas from the carb before it sits for a couple weeks or longer. That way the gas wont clog the carb when slowly turning bad. Also the Ethanol in the gasoline will catch water from the air and cause corrosion inside the carb. So just simply drain your carbs before the bike sits and "it`ll be fine". :)

[@JParkes43]

[@NubsWithGuns]

A big part of peoples problem with clutches is forming their opinion from thr cheap one that their bike came with. Also not keeping it engaged is a problem for where some have to ride. My Hilliard clutch has never smoked or gotten too hot, it is a racing clutch but I have the engagement at 2300 on a stage 1 hemi head 212 predator It loves to stay locked in also which makes for careful throttle until one almost completely stops

emulsion tube is what that is. The fuel is controlled by the jet and the air is controlled buy the emulsion tube. The tube will also be calibrated by the size of holes in it. That helps with the mixture of fuel and air so you will have a nice atomized fuel air mixture. If the holes are incorrect in size then the engine runs like doggy poopy Except for wide open trottle.
