Thank you for you for sharing ,it is a pleasure just to watch the step by step process,The work you do is number 1A+.
Thank You. Please be sure to share my channel/videos with others.
I'm a Mercedes/BMW tech (retired) Nice videos! As I watch you recommend red RTV. I would recommend Permatex Ultra Grey silicone. RTV is for rough surfaces, while Ultra Grey or Ultra Black is for machined to machined surfaces, covers, etc. It dries like thick rubber and is stronger, yet still easy to clean with a razor blade. Great videos! Real good job as I watch you do it I can tell you are a pro. Thanks!
Thanks for watching, and thanks for the tips!

Invest in a 1/4 inch cordless impact drill, it will cut your labor down to1/10 of the time.. just my 2 cents worth, otherwise great video, very clear step by step instructions!!
Hi Aaron. I was living on an out island in the Bahamas when this video was made. I now have one. Thanks for watching! Check out my "GY6 Scooter" video playlist below and share.

great info.
Thanks! Be sure to share my channel with others.
very informative, thanks for the upload. I have to tear my 13 jonway down to see why it ain't getting spark.
Leo Gerow shouldn't have to tear down just take out spark plug and put it in the boot,then put it on the frame while turning ignition on if you see spark your good! Then if theirs no spark its most likely your stator but before that is double check the blue wire with white line that goes into stator for loosened one hope this helps
Could be cdi, or
Hello,
I have same noise problem from the fan side with my 50cc moped/scooter. Now my moped starts but turns off while idling showing the same rattling sound. Does my moped has the same problem of starter gear which you just changed? Is it located at the same side as you showed? Thanks.
they look so easy on the outside but surely you need to know your stuff to take one apart and the put it back together to working conditions. Quite interesting. :P
I have taken all sorts of engines apart over the years. I was never afraid to attempt anything. Once you understand how they are made and operate, it is easy.
electronicsNmore as with everything, anything is easy once you know how to do it. I just wish i knew :P
Good job nice ...
Thanks for watching! Please be sure to watch my other great videos and share my channel with others.
Awesome Ty
Glad you enjoyed my video Cory! Be sure to watch my other GY6 videos and most importantly share my channel with others. Thank you
Do u have a part number for the puller u showed us?
Thank you! Very I formative. Mine makes a terrible clatter at idle and also will not go passed half throttle without bogging down. Will not go passed 10mph!
Doesn't sound good....
@@electronicsNmore
What does that sound like to you?
Just a carb problem for the bog?
Hi!
Thanks for the video.
I bought a motor like these but it doesn’t have the ignition coil, my question is what kind of ignition coil do I need? It has kick start. Thanks
You're welcome!

Greetings. My gy6 150cc's cooling fan looks shaking much and engine makes rattling noice. How could I fix this any advise please🙏
Absoloutely excellent GY6 Videos. But I still got a problem with Cold Starting. If I shoot gas into the carb air inlet it just about fires up. I have checked everything, electrical and auto enricher, as per your videos but it is still lousy starting. I do not know where to go now. Any ideas.
Hi Guy,
Lousy starting is a very common problem with incorrect valve clearances. Refer to my video on how to check the valves.

Your welcome.
electronicsNmore Watching some of your video's are you some kind of Mcgyver or something lol.
:-). Thanks For Watching.
I know it isnt the topic of the video but man... I wonder what can be done to keep the exhaust pipe from rusting so badly. My old roketa did the same thing and I felt like I was doing something wrong but letting it get that way.
Way cool video though, I never knew there was all of those components behind that shroud!
Hello Micah. Not much you can do besides sliding another stainless steel tube over the end. Thanks for watching!
Great video. Btw would u know where can I buy that part that holds the stater wires the one with the long bolts u took out or the name of that part? Cause my scooter don't have that part to hold the wire in places and the flywheel keep hitin it and cutin up the wires and I been tryin my best to fix the old stater over and over I have a brand new one put away but I don't want to fuck that one up lol until I can get that part to hold the stater wires I hope to hear back from u and great videos 👍🏽
At 10:20 in the video?
i had to weld 4 screws because twit stripped it before i bought bike, he even placed bolts to deep and messed to windings
sir please what the elbow for fan cover to carb what its job ?
I would think for cooling purposes.
vi crear vídeo... i would like that You playa the vídeo whit th noise before and after the change im
taking the same noise, non when i just start the enginge... bit when i acelerate the enginge its making the noise un that side
Yeah me too. I thought it was the valves needing to be adjusted but I only have a 50cc and all's I can get is an oil pump with a plastic clutch thingy?. Oh well, I'll pull it apart and have a look anyways lol
What if my starter clutch won’t slide off? I’ve already removed the nut and washer? Thanks.
Make sure there's no retaining clip or ring holding it in place. It should come out.
somebody to know, where i buy a enguine for a cpi scooter 150 cc 4 strok water cooled?. or parts
+iker ruiz
Cheapest place is www.mortchmotor.com
as a female I have great patience working on my 50cc scooter but when it comes to watching videos hell no!!! lol if all your videos are like this you are my new go-to guy! thank you very much for sharing this one it was great! I had a no spark issue with mine and I found out it was the pickup coil thankfully it's on the outside of the flywheel so easy replace. I took the old part out put the bolts back in the holes and waited six weeks for my new part to arrive, during that weight the wind blew my scooter over and one of the bolts disappeared never have found it! I found that out when I was replacing the new part. I installed the part no problem turned over the bike and it spun a few times and then the flywheel locked up tight!!!!! it won't spin for nothing!!! question is do you think that missing bolts slid behind the flywheel and it's stuck in their held on by the magnets so the flywheel won't turn?I can't imagine any other reason why the flywheel won't turn anymore as it turned just fine up until cranking it after installing that new part. I know this is an old thread so I really hope you're still around to answer this
It's a good possibility. Must be jamming it up. Thanks for watching!
@@electronicsNmore thank you so much for your quick reply! it's been driving me nuts knowing I have to go out and buy an expensive tool like that impact driver just to get the flywheel off to see if that stupid bolt is in there! LOL I actually bought another scooter hahaha this one a pony. while breaking it in at 40 miles on it last week it sprung an exhaust leak! sounds like some old dirt bikes ive ridden back in the 7os!and it gets way too hot in just a mile or two of driving it so here I sit with two great little 50cc tao tao s and no way to ride them! haha. do you happen to have a video on what to do about that? I only watch katchis kid and rolling wrench videos and now yours I haven't seen a video for 50cc Pony Tao tao yet .I have over 6000 miles on my old TaoTao and it never had a problem until the no spark issue replacing the part and now. the jammed flywheel but it's a bummer that my new one started acting up at only 40 miles!.T.I.A :) getting help from their tech support team is near impossible!!!
Is GY6 made by Jonway? I have a Jonway 150cc.
No Kevin.
Qmb139 scooter clunks badly when cold starting. Runs well otherwise, starter clutch then?
Only makes the noise when cranking
How about when you use the kick-start?
+electronicsNmore Thanks for the reply! I did two cold kick starts and it didn't make the noise.
Does that mean its probably the starter clutch?
Hey I have the same scooter as you, and I am hearing very loud grinding noise coming from the starter clutch area, is that where my problem is? It started slowly and soft, but as I kept riding it got worst and worst, so im nt sure if its the starter clutch.
Fabio Bandarra Hi Fabio. Do you have plenty of oil in the engine? There are several things it can be. Could be a bad camshaft bearing. You can inspect the camshaft bearing with the valve cover off. Make a short video so I can hear the sounds myself. Be sure to move all around the scooter and go close up as well. Post a link to the video. Upload your video to photobucket or similar.
Thanks!
I didnt have oil for a while, because of oil leak. After I fixed the leak and put oil back in. It was too late. I cant turn the scooter on, because I taken out the starter clutch to inspect it, the starter clutch is separated from the disc that its attached to, im nt sure if thats right
The middle of the starter clutch does pull out of the disc. That is normal. You have to push in all the lobes sticking out in order to reinstall the middle section. If you added oil, and the exhaust pipe is not showing any gray-white smoke, then the piston is probably OK. I would definitely check the camshaft bearing. Loosen the chain with the tensioner, then try moving around the camshaft to see if the bearings are OK. I suspect a bad bearing. They are cheap and easy to replace. You just swap out the entire camshaft. ALWAYS check your oil!
electronicsNmore thanks I will definitely take a look, I appreciate all your help, your videos are always helpful
electronicsNmore another question, is how can I tell if the bearing are bad, do I have to take the camshaft out and inspect or can I see it without removing, and if its nt bad bearing, how can I tell if the starter clutch is bad .
What size nut holds the flywheel on 139qmbemgine
Hi Kevin. You can find free service manuals online for GY6 scooters. They will tell you the sizes. Thanks for watching!
Did your oil pump chain have a lot of slack ?
No, yours must've stretched.
Any other symptoms with this problem, like slipping engine or transmission of belt?
+GARRY OLEARY
What problem?
I always use red Loctite and have never had problem removing things, Instead of using the blue i just use less red that way I only need to have 1 item around.
The red is really strong stuff(242/272). I usually heat up the nut with my propane torch for easy removal. Not too much heat is needed
@@electronicsNmore I am having a heck of a time removing the nut at starter clutch. I was wondering if I should try to heat it maybe that will help.
@@brenday01 You may need to borrow or rent an impact wrench.
my scooter shocks somethimes at speeds over 50 km/h is that normal or what could be the problem?
Sounds like a tire out of balance or a tire that is out of round.
i hope it its like it came from the engine on full gas it dont do it it only does it when i ride at the same speed without acceleration or decleration
why do you need that tool and why do you need to do all of that stuff just to take off a fly wheel?
My magnet is rusty is that why it wont make a spark on my plug
?
Could be a few issues. Refer to my GY6 troubleshooting video.
How to put the Flywheel back on?
Dylan Wilhelmi Very easy. Line up the key in the crankshaft with the flywheel, then slide it all the way back onto the shaft, then hold the flywheel in place using a strap wrench, chain wrench, or pipe wrench as you tighten the nut. Do not damage the flywheel/magnet as you hold the flywheel. It also would not hurt to apply some medium strength thread locking compound.
Thanks For Watching!
electronicsNmore thanks, I'll try that
Yo man could you check the video I just posted...maybe you could tell me what's going wrong with my scooter I'd really appreciate it!!
