Gotta love the old guy. It's a real pleasure gaining knowledge from our elders. And it's very kind of him to pass it along to us youngin's 😎
I really like this guy. It's clear he has tons of knowledge and tons of pride in his product. He also seems really genuine.
I couldn't have said it any better!!!
Wish they last forever
I got the mini bike I had always wanted as a kid when I was about 40. I bought a max-torque clutch for it and it was great. Thank you for making my dreams special. I really had a blast with that mini bike.
I used to remove all the shoes from my clutches and drilled each shoe with three holes (through the spring grove) this prevented having to change the springs as the shoes were now lighter. It was the easiest way I found to increase the engagement rpm.
Was there any issue with this?? Curious because I plan on trying it on mine with an upgraded spring to see if can get the engagement up to around 3500rpm
@@carrrsosa
I never had any issues at all. It worked very well. If you need more RPM, you just lighten the shoes a bit more. I never found that I needed to add a stiffer spring. One thing to consider though is that this may offer more slippage and therefore more heat generation. It could certainly get hot if you had a lot of HP and the cart or bike was heavy. :) try experimenting with those cheap Amazon clutches and see how it goes. 👍
@@thompsona10625 this is a really useful tip thank you very much I’m going to try this trick with a 3100rpm black spring to see how high of an engagement I can get. I don’t need to run my clutch very long I’m mostly going to use it for a mild drag build that I have. I will also probably will into the bell housing to count the clutch getting hot and cool it down a little more! Thanks for the tips will let you know how it goes👍
@@carrrsosa
You’re welcome! Have fun and good luck :)
Love this guy... reminds me of my grandpa...
Grandpa's are cool
Pls how can I get a racing clutch am in Nigeria please help
♥️
I really appreciate this gentleman sharing the information and specs that he does. There's other videos of him and their operation and manufacturing methods too. When I need another clutch I plan to buy a Max-Torque because of this man sharing the wisdom and expertise many people wouldn't.
Great video. Well explained. Great tips for saving money by altering a spring and cutting shoes to go from an ordinary clutch to a racing clutch. The owner did the video. They are American made. They just gained a customer for life. I am impressed. Going to buy a genuine MaxTorque clutch for my son's mini bike right now.
That last clutch shown is awesome.
What amazing guy I love how he talked about stoping the bike so true you can stop the clutch but the back tire will still move
There's no substitution for real world knowledge, and this man has that knowledge.
Thank You Sir for giving us the use and benefit of your knowledge!!
Jim is a terrific guy who has been very helpful with the clutch on my vintage West Bend kart engine
Very informative! The other day I rebuild a clutch and I know what he means by talking to God. I don't even know how many attempts it took to finally get all together. Once done it didn't spin freely so didn't do something right, it was an old clutch too but worth the practice. Thanks for sharing!
I'll say it again... This guy is super cool and I love his business model!
Someone should absolutely design and market the "lightened" version of the clutch at the end.
Pls I need a clutch to bye
L
Too expensive,lots of drilling
How much would you pay for it?
I agree with you about not using the clutch bell as a brake drum. Same as the old bicycles, with the pedal backwards, coaster brake. Chain breaks, no brakes.
I sand blast my drums on my clutches to improve grip for a race
@Skott both I would assume
Why would you do that? Have you noticed that the non slip area of the drum is worn from slippage? If there is no evidence of slippage what you are doing doesn't help anything.
Deucealive75 it actually dose
Deucealive75 When your rough up the inside of your clutch drum it as a texture It
helps the clutch Look up faster
So thats how they are made huh? Always thought magic worked a centrifugal clutch....🤪Thanks for this!
can't believe i missed this. kick ass.
Awesome video’ !!
It would be nice to have a video telling when it’s best to use a jack shaft and torque converter ?
This series has been very informative.Thank you,Sir,for showing your Company,and how things are done.I'll be buying from You.
very experienced, practical and smart man.
Not like some greedy business man, which don't share trade secrets. It is all there.
There is one thing I haven't learnt here, and that is how to make my own centrifugal racing clutch
You must have missed the part about cutting the spring for higher engagement RPM. Or the part at the end where the guy who races lightened up the clutch by drilling multiple holes. Or the part about converting from a six shoe to a nine shoe. And what about just buying their black spring so you have the highest engagement in the first place so you don't have to cut your spring.
Forgot the free part of it as well
Right? All he did was raise the launching rpm. Different camshafts have different powerbands(rpm ranges where the main power hits).
A modified/cut up/lighter clutch does not raise the HP or Tq limit it can take.
Cars have different friction material for a reason.
@@UnTamedMustang What makes you think that the objective here was to raise the HP or torque limit? The lighter clutch shown at the end was used for racing. It didn't need the HP or torque limit raised.
a better way would have been to say how to convert a regular clutch into a racing clutch.
Great video. Wish I would of had this type of info 15-20 years ago. Starting to feel old.
Keep riding
Gr8 stuff! YO, Old guy? What old guy? He's a spring chicken and has probably forgotten more about clutches than I will ever know.
This is the best video I’ve seen in a long time!
Low tech and simple, the best kind of mod
Thank you James for making such a great product made in the USA. Hope you live forever. VF
I truly enjoy the way he knows what he is talking about.
I wish I could give this video two thumbs up! So helpful. Also, love the background music. Gives me a Metallica/Cure vibe.
Glad you liked it!
Weight reduction clutch looked very cool and that's great info on centrifugal clutch modifications I'll use these tricks in the future I'm sure! But I'm liking CVT transmissions at the moment lol
Get a chain
Chain gang
What a neat guy. You must have had a great time spending the day with him.
Where my rc racers at that understand this!?! Lol awesome video Pa
That was very informative!!! 👍👍👍👍👍👍
Excellent video, thanks.
Imagene wining a race with this clutch. That would be cool.
Please how can I get a racing driver clutch
You need a camshaft DESIGNED for the launching RPM all the way through the powerband.
So much info is missing in this video and people are feeding on it.
@@UnTamedMustang you are thinking way to hard my friend. This video is lacking absolutely nothing.
This is most likely a dumb question but why do snowmobile clutches use a different style then the smaller ones? Is it simply that the springs in this style can't hold up or would the design not be able to keep it from slipping? Cars normally operate at lower rpm but I wonder why one couldn't be design for more efficiency for a semi auto clutch for a car?
Super good stuff. Between snowmobiles and scooters, I've had a lot of experience with different types of CTF's. Great info
very cool i learn alot about ciutches lets see more on torque convertors.
Cant recall name of the method but there is way to drill ANY conductive material regardless how hard it is. It uses rather small pipes of brass i recall, where welder power is directed and into tube cooling liquid is pumped that removes any particles that get melted by the electricity. Rather interesting to see holes in a diamond.
I wonder if they use the water jet to make the holes in the back plate
58yrs old and I learned a ton. I still build go karts and mini bikes.
Very Nice to See American Ingenuity still at work, especially when we have so many countries who rip off products like such, Predator!! Honda's headache and ripped off version of their own engineering designs!
I have a stage 4, 212 predator.. keep burning up my clutches.. need something that will engage at a higher rpm.. predator has the upgrade hot 265 cam..so now engine ideals at a higher rpm rate.. and wants to engage clutch at ideal..also when I'm running hard and let off the throttle, it wants to remain engaged..
Dude! What an awesome vid! That guy knows his stuff! Very Informative, Thank You!
Great information awesome product.
Once my Comet clutch wears out think ill get a Max Torque. But have it engage at the lowest RPM possible. Tecumseh 5hp Powersport idles at. 2200 rpm i think.
Love the video great info
Fantastic video!
i really enjoyed this video
Same. He's a cool guy.
this was awesome MAX TORQUE
Looks like a great product. I would probably purchase one if I knew for sure that it would work for a 10 hp. Tecumseh engine pushing a homemade single tracked vehicle something like the snowcat.
This is like gold!!!
why did you cut the shoes? does it help ?
Thank you. Very informative
Woohooo another edumacational video. Definitely interested in this 🤘🏻🐿🤘🏻 thanks for the info bud you rock 🤘🏻🐿🤘🏻
Too Cool 😎
Very KOOL gentleman I am way past being a kid but I have street bikes and dirt bikes but minis are just so much cheap fun Camp scooters
Just found your channel and Subscribed. Very nice work.
Have 70s MGW Wren tore the old block brake off put clutch brake on thinking about alternative braking previous kind of hard put disk on "Ideas"? have digital lathe going to check my clutch spins the tires wheelies 20 at idol 12 tooth assumed was racing the torque is outrageous thanks informative not safe bike race yet getting there
Way cool video. Some serious thought and design went into this clutch. What is recommended for a G6Y motor with 150cc's?
The car weighs almost 900lbs with driver and passenger.
It's a tao tao arrow.
How can I lower the rpm. My kids have a predator 79CC engine but the clutch doesnt engage. Just sits there and you can hear the engine just bog down.
Who males a strong enough 1" bore centrifugal clutch to work with a duromax 440 engine? Due to the size and space restrictions a 40 series TC won't work as pushes the chain out too far. I need a clutch that can be mounted inboard not outboard. I'm ready to ride this mini bike but have been stuck for months and the first Amazon 14T clutch I got burnt out within 500ft. I have to use a clutch not a TC. No more room to shift the engine to the right for a tc.
Mr. Donovan. How would you make a clutch engage at a lower RPM? This is not for a racing situation. I need the clutch to engage at just over Idle speed. The motor is a briggs 5.5. hp. .75 shaft with a 3-16th key way, I need the clutch sprocket to be a 12T -40BS chain. Or, where would I by a Max torque made to these spec's? Thanks for a reply.
Is there a good centrifugal clutch you guys would reccomend for the Duromax XP18He that you guys use?
I have a question I have a older go cart for my kids and it seams like it takes a lot of power to get it to engage.. kids r 4 and 8 so just needed it to engage better because I’ve cut the throttle back so they can’t go fast. This clutch gets hot… they ride it n the yard most the time and it’s not completely level and only one tire pulls.. (for now till they get good with it) it’s on a 5 hp tecumseh motor.. any help would b great.
I have a gc160 off a pressure washer engine i had laying around.i threw it on a bicycle....i have he max-torq clutch with a "5" marking on back plate where max-torq is stamped also.the clutch will not engage properly.only like 1 disc ingages.clutch gets hot.i assume its because the motor only revs about 2500rpm max acording to specs i found on that engine.i think my issue is i need an old briggs 5hp that revs higher?i think the max-torq i have doesnt engage until 1800rpm? Right?so i need different engine?
Do a review on the new stage 1 kit air filter dust cover colors and the header designs
I need a link to the cutters that he’s using to cut and bend them sprints, I just cut one link outta a black spring and I broke my small cutters and it was hard to cut it with my big pair, and definitely didn’t bend out pretty and nice like his lol
So I bought a max torque spring rated at 3100 rpms me and my dad installed it on my mega moto 80cc mini bike im wondering if because the rated engine/idle rpms are 1600 rpms if it'll slow down performance because it doesn't seem much faster on flat downhill it's about 35 mph 26 on flat or so before the spring I couldn't rev going downhill but It lets me rev it going downhill hit the throttle but doesn't seem like it made a difference in speed much so I'm wondering if going back to the stock spring or a spring thats the same or rated for lower rpms than the engine would engage quicker take if quicker and be faster Antoine know tge answer because my dad thinks the spring I bought might be too much for it thats why it's nor helping much
I realize this is an older video, but how do you feel about the 10 tooth clutches thay don't use a bushing? Any horror stories?
could this be scaled up to drive a motorcycle (2 wheel) with a vw beetle 1600 engine?
Great stuff. Very grateful for all of the information that has been shared in this series of videos.
Great video Greg and well clarified on the workings of a clutch
thumbs UP, Subscribed and now off to see what other clutch info Jim's posted in the 2 cycle world of racing!
Do I even need a transmission? I need to adapt this to my Harley but I need it to start engaging at 1500 rpm.
They make centrifugal clutches for HD too. Not this company but there's a few clutch companies that do and they're pretty awesome, but expensive.
Sooper-informative. Had no idea what a centrifugal clutch did before this.
I know this is a old video. But what do you call the shoes when trying to find replacement ones and springs? Build your own clutch but how can you when you can't find the parts?
what happened to the 2 stroke off road build?
I have a tincumseh 5.5 hp engine it has a 7/8 output shaft any cluches for this ???
that was freaking excellent
where can we buy some clutch shoes to cut?
Whats the max power one of these can hold? I'm thinking of putting a car engine in a gold cart and need something to connect the engine to the axel
Love you too brother AGAPE
Very cool
That was a cool video. Just to see the clutch...
Can you make a video for honda activa racing clutch ....
That was awesome 😎
what a great video, amazing
Huge thanks for giving us this video man 🙏
I wonder if they could make a 7/8 for push mower engines that would run chainsaw chain make a briggs chainsaw mill :)
Awesome video, thanks for sharing. Both my kids race karts and we use max toque cluthes!
Dudes got a PAIR. Ever messed up with an impact? Imagine getting your wrist snatched by a fresh clutch powered by a bench motor. Jeez.
This was a very informative and helpful video. Thanks for uploading this for us.
Mantap bang, terima kasih ilmunya 🙏🙂🙂
That gentlemen must have been a blast to hang out with he prolly knows so many tricks. Prolly more for the flat head motors when everyone ran methanol. They made great power done correctly. Guys like him are getting harder and harder to find such a great guy, it is really cool the knowledge he shares.
Yes sir my tramps was one of them.
What happens if I cut used clutch pads?
I always watch the old school ways to build and do mechanics. They just get straight to it
You killed the game with that very "informing" video nice tips thanks "Red"
So does this add more power to the back wheels? Im sorry if i didn't catch it in the video
So he only cut 3 shoes in half? What if you do all 6 shoes in halft?
im gonna try this one out
