GY6 49cc 50cc 100cc High Performance Racing Clutch Assy with Bell | 6-Groove Adjustable Sheave, Compatible with 139QMA 139QMB 147QMD Engine Scooter Moped ATV Go-Kart

Everything is solid.Works great.As many other reviews have mentioned ,the contra spring is VERY stiff .Its probably better suited for big bore kit.Doesnt take away from its quality. Switching around springs to taylor your needs is typical anyways.And glixal has other springs for that.

Works as they said it would

As other reviews have stated and the title states this clutch has 2000 rpm springs inside. It has both a red 2000 rpm big main spring & the 3 small red springs which is also 2000 rpm. It’s all pre installed when you purchase so it’s plug and play. Upon trying to install, this clutch is very tight. If you are thinking you can strong arm this by squeezing the clutch plates to push the belt through it is unachievable unless you are a body builder or can put down like 50lbs of force. I watched some videos of people opening these up with stock ones and most used their hands to squeeze the clutch plates. This one is impossible. I’m surprised to see how other reviewers got it on. My hack is to jam something inside to use as a wedge or spacer thus allowing me to shove the belt in first and then install it that way then I’d have it pre-expanded pre-hand with the belt in the clutch before installing. I am not a professional or a mechanic use at your own risk. What I recommend is using a screw driver. Get a screwdriver and hit it inside the clutch plates to decompress the space. People will say don’t do this it will damage the clutch plates. That is true if you don’t have the right tools. You need a small screwdriver first. It does slightly graze the metal as you are trying to pry it open by slamming a screw driver inside. What I would do is use a small screw driver first and use a mallet or something to hit the screw driver in the clutch plates. Then when it’s wedged inside get a bigger one when you have space inside the clutch plates. That way the big screw driver won’t be shredding the metal on your clutch plates as you try to jam it as a spacer/wedge as it will be too big to go inside and actually push against the metal thus damaging your clutch plates. Using a small screw driver has a smaller end point fitting it similarly to the edge of the clutch plates making a minimal to no damage on your clutch plates when trying to wedge a space in between. The issue I had previously was my clutch plate had a hard time opening and closing. The clutch was starting to seize so I ended up getting this kit and replacing it. This one has a very hard time to squeeze open and close which gives me great concerns as when you accelerate and decelerate the plates are supposed to expand and close. I’m going to install this and see how the kit goes. I’ll keep you guys updated. As far as what others have reviewed it seems like a great kit so long you can actually install it lol. Read the reviews lots of people sent this back because of the tightness of the springs and I can say they are not joking. I thought maybe those people have weak fingers lol. Nope the springs are just really compressed and strong. Overall from a look standpoint the clutch springs look brand new on mine. Clutch bell looks black and brand new. The pads on the clutch are all brand new. Looks like a good kit. Keep you guys posted after install. UPDATE AFTER INSTALLATION... I was finally able to get this Glixal 2000 rpm clutch into my moped and boy when I tell you installation was a pain. It was a pain based on how tight that clutch is. I could not hand squeeze the clutch plates no matter how hard I tried. I ended up purchasing a chizel set. I first insert a small screw driver to wedge open a small space. Then I used the bigger sized chizel tools to go higher and higher until i could get a sufficient enough gap in between the plates. I left the tool inside while installing it and put the belt inside the space in between the clutch plates. I then pulled the belt over the variator and the belt was barely able to make it on but it made it lol. FIRST RIDE AFTER INSTALLATION.. After I installed it I went ahead and took it for a drive. After taking it for a drive I realized it was revving higher but accelerating slightly slower than normal based on the first start. I have a 100cc Big Bore Kit so naturally my moped does not have a very slow acceleration to begin with. I also have 5 gram sliders. My guess is the springs are too tight so my clutch was slipping or the belt was not able to move freely because of the tightness. After driving for 5-10 minutes the clutch had time to settle in and I noticed the acceleration was different as it provided more performance from take off. Like a lot more. It also added a smoother acceleration throughout. Higher acceleration. Up hills I gained speed from my previous stock clutch. It also provided a higher top speed. Where I used to lack in reaching that top end power it no longer has an issue with that. I'm happy with the kit itself though results may vary from person to person depending on your moped. Overall it's doing what it's supposed to do. It accelerates way faster now. If you are going to purchase this please make sure you are up for the challenge in changing your belts because boy those clutch plates are tight and it is not fun lol. If the belt ever snaps oh boy I just pray that you have your screwdriver and chisels ready lol. Was it worth it? Definitely worth it. It's always hard to install things the first time but once you know what you are doing it will be a breeze. From what others are saying about upgrading the clutch springs is that it usually only provides take off power. What I noticed on my moped is it did more then that. It added greater acceleration throughout and higher top end. Not just a faster take off which it also did. This could also be because my previous stock clutch had a hard time compressing and decompressing as the clutch plates should normally. Overall I am pleased. Kit came pre installed so its just plug and play. All the springs are pre installed. Also as I mentioned above my moped is modified so for someone with a stock moped I couldn't offer the same advice. For my 100cc upgraded BBK moped its doing what its supposed to. I give it a 4/5. 5/5 for the performance it provides. 2/5 for those tight clutch plates OMG.

this clutch SUCKS. It's brand new and even after swapping out the 2000 rpm clutch and contra springs for 1500, it's binding, doesn't want to open even with proper grease on the guides. even opening fully it's still not wide enough for the belt to seat all the way like my stock clutch did. garbage! do not buy!

I put an 82cc BBK with 18.5 x 20.5 valves in my scooter. I needed to tune the CVT next. I installed this clutch with a new Glixal variator, 6.5g weights and new belt. I had a set of 1500rpm "Yellow" springs ready to go, that way I could see which set I liked best. With the 2000rpm Red springs I didn't like the feel of it. The engine had to be revving just too high. I swapped the 1500rpm Yellow springs in and that was a much better match for my bike. The engine engages right where I like it now and it has a nice response curve. For variator weights, I am currently running 7g sliders. I haven't tried using the different ramp angles yet. I plan on testing them out though. If you're tring to tune your scooter I would recommend buying this clutch plus a set of 1500rpm springs. That way you can give both a try. Another thing I would suggest is using a couple 8in long 3/8 extensions to compress the torque spring to install the belt in the groove. You use the extensions to squeeze the pulley how the belt would, using two hands. Make sure they are round and smooth and it should be easy.

So far so good. It’s only been 2 weeks.

I ABSOLUTELY LOVE this new clutch.. Great launches but the spring is too stiff for my 50cc to hit top gear.. pulls all the way up to top of rpm range though.. GREAT clutch.. I suggest opting for the 1500rpm spring over the 2000rpm spring for 50cc scooter.. or swap the main spring yourself which is what I'm going to ATTEMPT to do.. Otherwise it's an AMAZING clutch.. DEFINITELY recommend this1

This will FIT most 50cc, but doesn’t mean that’s what it was meant for. The stock spring in most scooters is 1000rpm. The spring in this clutch is 2000. Which means if you haven’t upgraded your scooter with any other performance parts, then installing this on your scooter will only slow it down. If you want something like this, with stronger springs then your stock clutch then I would recommend getting 100cc big bore kit. Bigger main jet, & better air flow in your scooter first. To sum up, if your trying to replace your clutch Bc it broke or something then buy a clutch with 1000rpm springs. You can look in the details on Amazon to find out what springs come with the clutch. If your looking to upgrade your clutch then sure this is okay, however if you notice all of other people commenting on the red 2000rpm spring that comes with it. That’s cause it’s too hard in most cases. IF YOU INSTALLED BIG BORE KIT. then you should be fine with yellow 1500 springs. You can order it separate with this part and then apply it. But be warned! The bolt that holds the clutch together is easily stripped. So you take it off to change the spring and when you try putting it back together you can’t fit the bolt on all the way Bc it’s already stripped. WHAT I GOT: I have a scooter with 100cc kit. New gas lines, air filter, lighter rollers then stock, performance CDI. So I did a couple things to it biggest being the bore kit. I got this clutch & the red spring (2000rpm) is like most way to hard. So I got a 1500rpm spring from the local shop. When the clutch got here it look fine, took it apart and switch the springs. When I tried putting the bolt back on it would only start screwing in at an angle Bc it was already stripped. I only took the bolt off once. So I ordered the part again…. Part 2 of this review will be when it arrives.

The clutch is great works well

Supérieur à l'original

Like other reviews, I changed out springs for lighter. I also needed to sand torque driver because burrs were making it tougher to open and close. Now with 1500 springs it’s great and reliable. But 1st you need to do some adjustments. Great for price but not exactly plug and play.
