Great video, I had questioned the T/C on how much MPH I can get out of it! Now that I know I can change the springs I might consider it a little more!! Another great video🤙🏻
Thanks! I got into the 60's with a TAV. Check out the Coleman CT200U-EX and Mega Moto 212 playist for more videis with the TAV. ua-cam.com/video/X0SmAZJ6qW8/v-deo.html
I’ve wondered the same thing. My 212 mod 2 is pulling good just top end isn’t where I want it. I’m topping out at 45-47 just want a little more,( without redlining the engine)but I don’t wanna effect my bottom end too much ! Maybe dropping rear sprocket from 60t - 58t would be the easiest / cheapest change ! Any input is welcomed 👍
@@kylesyx8432 Yes! I have gotten a 60+ MPH top speed with a TAV on the Mega Moto bike running a 40 rear sprocket. If you haven't seen the video check it out...ua-cam.com/video/2GxryXDUkt8/v-deo.html
Ended up with a yellow spring in the tightest hole for my hill climbing bike. I think it was more important with the Comet driver. With a Juggernaut, wasn’t really needed, as the Juggernaut stays in a lower ratio longer on its own. It be cool to see some 1/8th mile times and hill climbs if you get the opportunity.

Try an overdrive Lockout ring as well. It's a small spacer that slips over the brass bushing on the driver pulley under the belt. Depending on how wide you make it, it prevents the pulley from going into the 0.9 to 1 overdrive, which can sometimes severely hinder the engines ability to hit it's max RPM ranges, where it actually makes it's power on some built up motors.
Switched from middle to last with stock red and could feel more torque but thats about it. Small difference but definitely there. Apparently a spring change can shave decimals off of acceleration times but if you're not drag racing or climbing there must be little to no point in bothering. Thanks for the testing!
You are awesome this is where I'm working at now trying to find ways to get my jackshaft running I can only top out 39mph Governor bypass racing jet with the stock 18 lb valve springs and a 37 tooth on a rear I can only do 30
I ditched my 38 rear sprocket I had on and put my stock 50 back on. My setup engine wise like yours, I'm just running a 20" tire and it liked that gearing better. I'm probably heavier than you also at 260lb. I've topped out at 58mph. Great video though always enjoy, keep the content coming.
How does one account for weight. I have a stage 2 tilly, vm22, and juggernaut. I weigh 240. Running 19” tires. I have a 42t,46t,and 50t. In this video its a 4:1 ratio. To get similar results with more weight is 5:1 better?
Yo, got my juggernaut yesterday, and installed it today. Im calling it the jigglenot from now on man bcoz its smooth. No vibration at all!! Idk why u guys say on stock engines you wont notice any difference. Sure my top end drop from 60km/h to about 47km/h, but trust me, the trade off for comfort is worth it. Beside i think i can get back up to 60 if i change the springs in the driven. Jigglenot on a honda gx100, 10t x 56t sprocket on a 26" wheel bicycle.
They also make stronger clutch springs for a clutch that engages higher in rpm, and you can make lock out ring that lets it stay out of overdrive, if you make it right you can get 1 to 1 or 1 to 0.9 ratio which should let a high revving engine actually hit it's higher ranges without too much of a struggle.
This is what I'm curious about, I'd like to see a tc with a stronger spring maybe even different weights in the stock style driver and compare that to a juggernaut @black66
I've seen videos where guys measure the distance between the holes and add another one past the third for Max tension on the spring, might be worth a shot.....
You should now do a series on attempting to make it street legal. Buy and install turn signals, side mirrors, brake lights, and maybe even go to the DMV? would be awesome
That would be pretty dumb since laws are not universal and the information in a video would only apply to a small subset of his audience. It's not hard to make these bikes legal for the street. A simple Google search of " how to make minibike legal in (your state) " will give you a step by step guide that will actually give you truthful information. Black doesn't know the laws where you live. That's your job to figure out.
Black 66 thanks alot for sharing this. I always wondered what difference the springs and position made…i just put a 224 mild build with cl1 cam on my bike like this with stock jackshaft. It goes 44mph with a 40 tooth sprocket and 21” tall tires. Maybe its time to put the torque convertor back on it with a juggernaut👍
Sure with a Juggernaut. Try that with the stock driver. I tested this for the fun of it and the green spring went right in the garbage. With the stock driver you want the red spring in the tightest hole or better yet the yellow spring.
I love your comparisons and really enjoy your channel. What is your body weight so we as viewers can compare what we should see? Keep the videos coming sir! ✌🇺🇸🎥
Got all new parts but I'm having some belt slippage on the back pulley. Everything's lined up nice an the belts the right size.. Think the green spring would help grab the belt better? Or maybe have an idea of what other things to check? Normally if I have this issue it's the clutch which is an easy fix. Anyways love your contact keep it up man.
From what I've seen, the spring adjustments really don't affect the juggernaut torque converters. Regular 30 series drivers have overdrive, and I've seen that changing spring positions and changing springs will greatly affect the top speed and acceleration of standard drivers. Maybe your top speed doesn't change much because the juggernaut doesn't have overdrive?
The recap should be that there's no noticeable difference with a Juggernaut unless you have a stopwatch. The springs make a big difference with the stock driver but are a waste of time with the Juggernaut.
Edit: seem like its designed only for high reving engines. I just want a driver that wont vibrate on my stock engine. Do you have any suggestions? Nice, thx man. Im gonna buy a Juggernaut driver. My amazon driver tends to come out of balance and vibrates. The 40 series uses rollers too, i was thinking to cut channels in the weights and weld rails in the "bell" so the weights wont have free will. But now, juggernaut. Maybe in october or next month. Good timing too bcoz i was gonna buy garter springs. Great vid man.
If you are using the stock driver the green spring in that position is the worst. He's using the Juggernaut driver which is very different. Put the red spring back in the left most clock wise position and notice much better acceleration (0-30). The Juggernaut wouldn't work very well with the 60 tooth.
I never knew you could do that with a torque converter. two questions: is it possible to put the electric motor on a big frame like this bike ? And is there a way to switch one of the gears on a jackshaft? You know it got a 20 tooth and 10 tooth sprocket. Is there like a 11-20 tooth you could swap out for it? I got a mb200 with rear shocks and I'm not able to put a torque converter on it because of the frame and Im not sure if I can one chained. So I'm slowly now days😩
An electric motor would be easy to put on a big bike. There is a lot of room for all the components. I think running a QS138 on a big bike would be awesome! Yes, there are different gear sets for the torque converter.
IDK...THE NUMBERS ARE SO CLOSE AND ANY NUMBER OF VARIABLES LIKE AMOUNT OF GAS IN THE TANK OR SLIGHT HEADWIND COULD ACCOUNT FOR THESE SPEED DIFFERENCES.
Can anyone please tell me what kind of back tire I need for my Coleman ct200uex I live in the hood. I bought a street Tire and ended up having to put seven plugs in it. I need a all-terrain tire that is good for 70 mph. Any help would be greatly appreciated it's hard for me to buy parts. I only had that Street Tire for 3 or 4 days and had to start plugging it.
I’ve been very curious on this subject lately. Curious to know if you have tried a top speed run in the first hole? To my understanding the first hole gives the most top end and the third hole gives the most torque
Sort of. The more you preload the spring, the more it holds the engine at a higher RPM. It's like putting your car into sport mode, keeping it a gear lower. It will still go the same speed, it will just get there quicker from being in a shorter gear. At the cost of fuel economy and extra wear and tear from the higher cruising RPM.
@@WyFoster so i have a brand new green spring as well but haven’t installed it yet. Is the middle hole the best option for all color springs? Theres a couple videos on YT showing that the juggernaut likes the 1st hole for the least amount of spring tension
@Marquis Lewis Really depends on your engine build. The more aggressive it is, the more preload. The green spring is stiffer. It's like if you came up with a 5th or 6th hole for the red spring. Not a magic bullet. It's more of a tuning aid. Most of the magic is in the driver clutch in terms of stall speed.
@@WyFoster The green spring I got must be defective. It has the lightest tension of the three and the worst performance with the stock driver. I use the yellow spring in the tightest hole to get the highest RPM at the belt shift. 800 RPM higher than the green spring.

Thanks! It's running a 10-tooth front sprocket
Not so patiently waiting for your yellow spring comparison to green and red! I’m looking for best acceleration!
I have so much stuff going on right now. I'll try and get to it.
@@Black66 start working out now you need to be Hercules to put the yellow spring in 😂😂
@@jamesa6272 I'm skinny , I might not be able to get it in there lol
@@Black66 I take the driven off. Wind it and stand on it and pray to get the clip on
Black66 must weigh like 140lbs after a double whopper to get these speeds :)
How about the yellow spring compared to red?
So to recap, the first hole far left has the best top end, and the hole all the way to the right has the best torque
The recap should be that there's no noticeable difference with a Juggernaut unless you have a stopwatch. The springs make a big difference with the stock driver but are a waste of time with the Juggernaut.
