49cc Clutch Quick Fix Tip with a Bike Not Moving

Let's look at why you don't get any response from your 49cc engine when you lay on the throttle. This quick fix tip will hopefully get you on the road again! Thanks for watching and be sure to like and subscribe!

THANK YOU!!!! That little bit of spring tension change got my bike to haul this 220lb man to 28 mph, and on a dirt road. Now I want a bigger engine and disc brakes!!! These machines are a kick in the pants!!! Thanks again!!!

Just save me a headache, Thank you! I put new clutch in the kids mini moto dirt bike and it was slipping but eventually grabbed, I could smell burning clutch right away. Much better now thanks.

[@tedbenavidez6344]

Thank you. For your video. You stretching out the springs. Just perfect as to what to do with my 49cc. Your my genius motorized bike mechanic. After 9 or 14 videos not one of them showed what you did. Thank you so much

[@gcasey38]

So is it a good idea to check one straight out of the box

[@standtallvets5386]

I had a go cart years ago with a centrifugal clutch the same size that was not enclosed, and it had NO springs on it. Worked great. The centrifugal movement itself is so slight that springs would have caused even more wear on the pads making them slip more before fully engaging, and wear out much sooner. The pads movement is so small that by stretching the springs in this video is the same thing as no springs. Although if one spring eventually broke stretching or not stretching it would destroy the whole clutch.

[@infinitesimal69969]

Thanks for the info. i have the same 49cc 4stroke with the belt drive. The clutch grabs at low rpms, and the engine shuts off, making a squealing noise as soon as the load is on.

[@mbrrideitlikeyoustoleit8436]

THANKS FOR THE INFO ON SPREADING THE SPRINGS....This clutch set up works awesome 👍 I put a 16mm Keihin carburetor custom intake and custom exhaust pipe. 40t rear sprocket she goes 45mph and sounds mean. As soon as I got my kit I did what you said to the clutch springs right away. so I didn't burn up any of the clutch and packed it full of high temp grease and works awesome 👍

5:39 you are going to get clutch residue inside there no matter what you do man, those clutches are disposable, that is why they are usually less than 20 bucks. they are more like brake pads than than a car clutch or even a 2-stroke bicycle kit clutch. brake pads are disposable. on a car they generally cost allot more than that clutch, but they also last allot longer. 8:50 no, you don't need locktight, tapered shafts lock themselves through use, do you use locktight for you drill press which is on a taper? mine doesn't even have a screw. you don't even have to tighten the clutch on at an insane torque. if held on enough it will tighten itself. my best luck on these honda gxh50 clones (i have 3 of them now) has been the jrl 2 lobe clutches, the 3 lobes have always given me problems, and there is a 4 lobe 30 dollar clutch available that provides great performance but is insanely rough and makes me think it might break the bell on my transmission. but these things are disposible, the jrl racing clutch is about 10 bucks on amazon and usually lasts me up to a month, but sometimes a couple weeks, and that is fine because i spend almost nothing on gas in the meantime. these are gocart engines and when used on gocarts at a theme park or something like that the clutches get changed out daily. i will reiterate again: these are disposable. the 3 lobes suck as a general rule in my experience (i have gone through 10 of them) the 2 lobes are pretty nice and reliable (like the jrl racing one from amazon that i mentioned, (i have gone through around 20 of those and not all of them were the jrl racing one, some were the more expensive ones that turned out to be identical) and while this fix MIGHT make your clutch work for a little while, it also weakens the spring in a spot that could cause the clutch to break and damage the transmission. but you are very right that on those cheap chinese single chain transmissions (btw i prefer those transmissions so far, i have tried the double chain (the bikeberry one) and it maxes out at 25mph like it has a speed limiting thing, the rpm on the engine shoots up like it isn't engaging anything anymore and i contacted bikeberry and they said it was rated for 25mph and wouldn't accept a return, and i haven't tried a belt drive) the cheap single chains need to get a good greasing. also i had to rebuild my bikeberry motor because of my own mistake (low oil) using my older cheaper honda gxh50 clone (i bought that whole bike kit for less than i bought just the bikeberry engine) and when i had them both apart i noticed that inside the cheap kit from amazon it had higher quality parts, like bearings for the crankshaft and piston connecting rod which happened to be the parts that i replaced, and a larger diameter piston, so i had to use the original piston for the rebuild. bikeberry sucks and their customer service is shit, only use them if you have no other choice, because they do have a good parts selection. (oh, and i didn't just use the cheaper engine because the muffler mount on the block was completely unsalvageable with what i have in my workshop, you would have to grind, weld material on then grind again, redrill and tap the right muffler mounting hole and i don't have a welder) sorry for the wall of text and i congratulate you if you have read it. just a train of thought post, i usually don't actually post them, but i have decided to post this one.

[@SouthernCustomCC]

Thanks for watching! I agree with a lot of what you said, but I think you should try the g7 belt drive transfer case on your next build. The bushing needs some attention once and awhile, but the clutch is much more reliable and there is much more torque on the low end without taking away top speed of around 30. Thanks for contributing to the community with your insight! Happy building.

😂...sorry! I’ll address that in future vids. Thanks for sticking in there

[@iceyaj3167]

mine was gone. the clutch arms that hold the pads together are gone. one of the arm broke off and lock up the whole thing. didn't drive that thing no more than 30min. my brother was the one who was dogging it. we did notice some thing was wrong in the beginning. it wasn't moving as fast even though the engine was running half of its speed but we though it was normal since its our first centrifugal clutch drive. 30mm later the engine lock up and find out the clutch assembly self destructed. i was piss.

[@bassjumpblues3631]

I honda goes forever on the clutch it is provided. These engines are only as good as we improve them! Let's keep on having fun in the meantime!

[@iceyaj3167]

@@bassjumpblues3631after the factory clutch went bad i replace it with a ebay knock off clutch. so far the clutch still held up to this day. every time before i make a long trip i open up the bell housing to inspect the clutch and see if the clutch is suitable for the long ride but so far i been noticing it only have normal wear. i begin to have fate in these clutch. i came to a conclusion that the clutch material that comes with the engine are made from a cheaper material. i've been thinking installing a CVT on this thing. we'll see about it.

[@pitapitabread]

i got the ebay 49cc kit with a belt transmission and it's good except either the clutch flyweight or the drum bell vibrate a bit at full throttle

Thank for this, i got new springs cuz they snapped but my clutch is still good. Hopefully works on a 49cc dirt bike.

[@robertrondeauu2481]

He dont explain what the springs do. Spings have tension. They throw out the clutch to grab the hub at a certain RPM. If to loose the bike will take off once the motor is cranked. On the other side if to tight or strong, it will take a lot of RPM to throw it into the hub. If ur adjusting the springs be careful with it. And when u start the bike make sure ur gf isnt in front of it waiting to go get a burger. Research it before u play with the springs.

[@larryshaver3568]

Holy Moses! that really got toasted

[@kght222]

no, it didn't, although it was a shit clutch don't get it twisted, at theme parks using the gocart version of the transmission and the same engine they replace the clutches daily and clean them out every few days. it is a disposable clutch. that is why most of them are less than 20 bucks.

[@ediot.1012]

Why isnt the clutch have a key in it, that might be part of the problem if its rotating on the shaft

Great video Mines was doing the same I was smelling burning while operating it noticed the tension was kinda lose and i tightened the tension adjust the chain took it for a test run and the burning smell stop it pick up speed and no one is saying but this engine has a two speed transmission

[@andrewholm6341]

Does anyone think this engine would be louder then my 49cc common AliExpress Plastic red casing 2 stroke? You know the one you see for sale all over online , tryna get a bit quieter on my stand up scooter , maybe a wee bit more speed

Mine wants to take off as soon as I pull the cord, and stationary it won't move at all. Any advice guys?

[@MrThatnativeguy]

Alexander Gill what transmission/ crankshaft do you have?

[@matteodalessandro158]

it's probably idling high, there is a screw in the bottom of the crab under the pull start that you can loosen and tighten to adjust the idle speed.

[@axyglx]

guys if you have the same symptoms, my problem was that one of the clutch pads came loose and was engaging as soon as I pulled the cord. I just ripped out the shitty oem clutch and bought a new one for £20/$30 and it works fine.

I have the same problem. Did it help with the wear of the clutch, because my clutch was gone after 5 miles of riding. Thanks!

[@SouthernCustomCC]

Kris Pau : yeah...its the springs! The clutch has been sitting in the assembled engine for who knows how long and it locks it place and becomes dust very quickly. This method is a quick fix. It will help until you order and receive a new clutch. If your pads are gone before doing this, then it is already too late.
