Minibikes: Torque Converter vs. Centrifugal Clutch

John and Ike make modifications to get the mini bikes running properly (John's needed a carb jet and Ike's had a bad carburetor), we do some testing, Ike goes off a jump, and we try a hillclimb.

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.

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.

In England we would say 'Emulsion tube'. Also, don't you have a jet and needle pair? I was taught [ in the 80's on 70's Mini Engines ] you should change them both.

At 6:57 When John started the bike I thought it had a purge system because Ike was spraying! 😂

[@JetSkiBuyFixPlaySellChannel]

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

[@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.

[@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.

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.

thanks for sharing all the vids and building of these mini bike I have a motovox and just put a predator on it a few weeks ago and it was so easy because of yalls videos but so far I'm not having any trouble with my clutch and it a $17.00 eBay special

[@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.

[@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.

[@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.

[@jaredcox2648]

[@michaelangelod5008]

[@victortallerbushcraft442]

[@patthesoundguy]

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.

[@CMoneyAdventures1992]

Does the torque converter work in low rpm as well as high rpm? I have a chopper mini bike I'm putting a 212 predator on. Wondering what your ideas are for prime setup. I'm wanting about 40mph or better from it.

[@Ledface117]

I would love it if you guys would do a go kart build with a Lifan 125cc pit bike motor and make a shifter kart out of it. I think it's about time you guys graduated past just doing predator 212 builds. Do you guys ever talk about making a shifter kart?

[@carlosadkins9221]

I'm thinking about putting a yanmar 5.5 hp diesel with a cvt setup on a mini bike not looking for big speed but looking for big power/torque... what do you think ?

Great video buddy. Question, are those bicycle handle bars on those mini bikes? The reason why I'm asking is I just bought a brand new Coleman BT200X and the handle bars sit real low on the bike and when I adjust them forward they still sit low so I started thinking about my dirt bike handle bars when I was a teenager and I was wondering if I could use those on there. The dirt bike handle bars sit up nice and high. Anyway keep up the good work guys and take care.

[@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.

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.
