Thank you very much for taking the time to make this video. Your work has gone a long way to help give me confidence in working on my scooter.

Best tutorial on CVTs on KZread.Very detailed and helpful.

Thanks for taking the time to do this, theres no manual for my bike and this is better than a manual.

A ridiculously in-depth step by step tutorial. They don't get better than this. Well done and thank you. I managed to do a full clutch service.

very informative. I enjoy how your videos are always formatted in a straightforward easy to understand manner as well. thanks for what you do!

Thanks for this. Brilliant advice, not just on how to take apart, which is what so many do, but explaining to the layman what you need to inspect, and not replace if not necessary, regardless of what the book says.

It's thanks to people like you that make in-depth videos like this full of knowledge that other peeps can fix their scoots. Thanks a bunch, man!

49ccScoot, could I ask a question regarding my scooter? Around 4 years ago I disassembled my Aprilia Sr 50 2000 Air Cooled scoot and left it like that. Around a month ago, I decided to rebuild the engine and hopefully bring it back to its glory days. I am assembling all the parts and watching as many YT vids as possible, but I only have a problem with the starter clutch behind the variator, more specifically, I just have no damn idea if I am supposed to have any washers behind the variator. I have so many parts from when I took my scooter apart that I am trying to figure out where everything goes. In this scooter, you didn't have anything separating the two parts. Would it be dangerous or problematic to the engine if I, say, didn't install anything in between that I was supposed to in the first place? Cheers, mate, your videos are a godsend! I'll let you know when I manage to finish.

Just started to work on a jog, your demo is brill and has covered all aspects of a service. Many thanks keep it up. Paul Allen

Thank you so much for the speedy response. I figured out that it wasn't the fan giving me the grinding sound. I am about to take everything off to inspect. Thank you again. I'm sure I'll be frantically commenting with you very soon. LOL! :)

best video ive seen about cvt services

I've watched a few of you're videos now and they all have really clear and concise information on every part you're working with. Thanks for all the hard work you've put into them.

Awesome! My wife's scooter died, and it turned out to be the drive belt was completely toasted. It was a mess in there, but with this video, I was able to get in, take it all apart, clean things up and get her back on the road! Thanks for sharing!! Respect!

man i learned more in the past 30 mins of watching you than the whole 2 years ive had watching other mechanics working on my scooter. now i am fully confident that i can do these things myself

Nice! Good luck with it. If you have any trouble, you know where I am here or you can get help from a whole group of us on the 49ccScoot forum.

I used to tear apart my cheap 250cc Chinese scoot to replace variators, belts and inspect the clutch. I now own a Burgman 650. Man, I don't want to even think about the clutch/belt on it. I guess why I purchased the 5 year warranty. Good video for those who may be a little intimidated for doing their own work..

awesome video from start to finish

Amazing video!!!! explains in a good manner how "the whole thing" works :)

Man what a detailed video. This thing is like a school.

Superb informative vid. I followed this and put my malossi variator & spring no probs. Saved me money - thanks

Thanks so much for posting this video! I have a 2007 Baja SC50 with the QJ1P39QMB-3 motor mated with the 1E40QMB Jog/Minarelli CVT that uses 2 stroke CVT parts that look like the ones in this video. The clutch and variator look just like the ones in this video but the CVT cover is different and unique on the Baja. It is a big help to see a CVT that actually looks like mine being shown! It took me awhile to understand why videos showing typical Chinese scooter CVT's were using parts that didn't apply to my scooter. It was even more confusing as Baja also made another version of the SC50 in more recent years that was basically the same scooter as the TaoTao ATM50-A1 and Jonway YY50QT-6 which does use a typical Chinese CVT and has the more common 139QMB motor. QianJiang scooter who made the QJ Baja SC50 as a 4 stroke also makes a 2 stroke motor version that is rebranded and sold under various names. For anyone finding this video and comment that has this Baja SC50 {Keeway Hurricane body style} with the QJ {QianJiang} anomaly engine and 1E40QMB Jog/Minarelli style CVT just remember that it is the variator with the 21mm inner slide bushing and 15 tooth spline that fits the Baja and the 15x12 rollers that fit the variator. I would assume the performance variators and clutch assemblies and springs for the Jog/Minarelli CVT's will work on the Baja too. You can get the stock variator parts and rear clutch assembly and springs here www.scrappydogscooters.com/50CC_2-STROKE_PARTS.html and the hard to find 836-17-30 CVT belt here www.scrappydogscooters.com/Replacement_Parts.html I'm not trying to promote their parts on your video and you can find these parts other places like ebay but anyone with this QJ Baja SC50 will have a hard time finding these parts especially the CVT Belt until they realize it uses the 1E40QMB Jog/Minarelli CVT parts so I'm just trying to help anyone with this scooter. One other thing the engine on the QJ Baja is slightly different but any big bore kit up to 72cc with the 47mm or smaller piston should work. The 80cc big bore kit being called 100cc by many sellers with the 50mm piston won't fit this Baja without enlarging the opening on the case. Also remember the variator rollers that come with some big bore kits are 16x13 and won't fit as the Baja uses the 15x12. The CVT gaskets that come with the kits won't work either.

+photonrayswaves Good info. They are oddball engines. I'm not sure why they thought it was a good idea. They don't seem to perform much different than the typical 139QMB that's easier/less confusing to get parts for.

A perfect video just what I was looking for thank you.

First class post! Covering every detail, I'm going to attempt this for the first time on my Aprilla mojito 125 cc in the next few days. This video will be right by my side. Excellent tuition, will let you know how I get on.

Very comprehensive video. This video ought to be linked by the manufacturers as a service operation or along with their service literature or something.

now it's so clear, thank you.

Nice job, I've used a HF oil filter wrench to hold the variator in place on my 4 strokes. They have one that locks like vice grips too.

Great video. Thanks for sharing!

awesome bro!! thanks for taking your time and making the vid.

Ok Vert I think you are right on the mark I will give it a check and keep you posted how it works out,thanks,peaceout

Awesome video. Thank you very very much! It is a great help.

Alright, I'll try that. Thank you very much for replying :-)

I think your variator should have 2 holes int he front where you can put something to lock it. The tool is shown in the vid, but you can make one with 2 metal bars and a couple of bolts that will fit into the holes, plus nuts to secure the bolts to the rods. You could also use a strap wrench to try and hold the flywheel on the other side while removing the vari nut. An impact and sockets are good investments though. Those will help with a lot of jobs.

Thank you so much for your help :)

3 days from buying a SCOOTER It fails. Brilliant video on what to expect in the transmission. Sorted problem - broke the sheave plate but new one on order. Will put together for the weekend. Thanks.

Good learning video

Dang oh well thank you for your time and Ill go Google that right now. Well thanks again.

I ditch the gasket most of the time, because there's nothing that needs to be sealed in or out for regular use. Sometimes starter setups will be picky with just the small amount that the spacing is off without the gasket though. One thing you can try to keep the gasket in good shape and so you don't have to mess with it is to apply a spray on gasket adhesive to 1 side. Use a thin film of grease on the other. It should stick to the case or cover but let the cover be removed easily.

Thank you

good video
