First I want to thank you for this video and the sharing of your knowledge. Thank you! I'm working on the same engine for a friend of mine. I've worked on plenty of motorcycles, ATVs and all makes and models of passenger vehicles but I was so unfamiliar with CF MOTO as well as all Chinese brands. After much electrical work and a tear down and cleaning of the carburetor I attempted to crank it up with full confidence it would fire right up. Nope. Long story short... my friend had messed with the valve settings without my knowledge. After trying to find some decent info on this process for many hours with no luck whatsoever I thankfully came to your video. Thank you for being clear and thorough during your guidance! This was truly a blessing to find. I haven't even done the work yet but I'm confident that it will do the trick. Oh yeah, absolutely gorgeous terrain you have up there to enjoy! I'm way down in south Louisiana swampland and just a tad bit jealous of your location. lol just kidding. Thanks again! Have fun and be safe!!!

I have the same thing happens to our 2017 traverse , it was the 75000 mile mantanance service schedule was not done yet. I'm going to try this rite quick

Amazon and VMC Chinese parts website. For engine parts this is a CFMoto Scooter engine model 172MM. You can search the Webbernet for parts that match that engine as well.

I tapped gear on new shaft. Just put oil on it so slide on. It's tight once it's on.

Hey I have the same go kart as you i was wondering if you know where to get parts I need a rear shock and a motor

"Two foot code". I placed the spring as you sugested. Worked like a charm! 2 months in and no code. Thank you buddy.

Hi, Any idea how to adjust a later one, my clutch looks very similar but theres no adjustment on the inside, on the MAG side below the clutch lever is a 17mm nut with a x point on the middle, screwing the x point just seems to lift the arm up and down without making any difference.

Mate, this is the dumbest ever. All this work... go and but a dial gauge with a couple of adapters all in one kit. Is your time that worthless? It is also pretty hazardous smacking ceramic material with a hammer. No cautionary advice given. Give up and go watch TV.

Thank you Sir!! You are a genius!! May God Bless you and keep you safe always!!

Thank you for the great video!

I went to a local repair shop put his $10,000 dollar snap on scan tool on my car no codes like that. i had service traction control and stability,and abs on my dashboard. It came up with 2 different codes i don't remember what it was but he cleared all the codes but came back on 30 minutes driving back home. So I decided to go ahead and replace the left side wheel speed sensor what a pain trying to get the old one out trying to carefully get it out it broke of i had no choice. I had to pull everything off the left side wheel bearing Hub was stuck on so bad took for ever after spraying it with PB blaster letting it sit and using a big hammer it finally fell off it was so rusty like no grease at all i ended up drilling out the old wheel speed sensor cleaned it up sprayed the hole. Used a small wire brush to clean inside the hole where the CV Shaft is put the grease down on the CV Shaft and the wheel bearing Hub. Put everything back together and still lights are on for ABS and service traction control and stability lights are on the dashboard any help would be appreciated ty

The oil drain plug underneath far left side of crankshaft cover

2 Years ago i paid a dealership 600 dollars to replace the brake pedal and sensor. It just started doing it again. This video just saved me lots of money. The spring length I used after cutting it down was a little less then 1 1/2 inches not measuring the hooks. Cost me $2.59 and some time.

This totally solved my problem! I am about a year out from this fix and still working for me! Thanks so much!!!

How did you get the bottom panel off so you could get to the pedals and install the spring?

I must say after multiple aggravating conversations with Firestone. This one that guy that his sister. The spring is such a smart idea and did the job lost of money lost over a simple $6 home depot fix and some brain power !!

Goldmine of info, thanks so much

Is this downloadable? Do you have a pdf link?

I have no idea what I am doing when it comes to engines but I have the exact same buggy as you, I'm using your videos to help put it back together. Please could you help me out on the drive system, how the forward and reverse box attaches to the engine. Thanks!

Have you tried to hook up at tachometer sir? I tried tapping to the b/y line from cdi to ignition coil and the tach goes all the way to max reading even its in idle. The weird thing is accidentally tapped into the kill switch line b/w and i got a decent reading.

Hello sir. I would like to know where to connect the carb auto choke? Thank you

I found a slightly low air PSI in a tire solved the traction control problem.

thank you for the info. hopefully i can find/purchase a SM. now that i have spark and new carb, engine will run if i feed carb fuel inlet but that "Vacuum" style fuel pump will not pick up fuel. i did disassemble it and the insides were as bad as the old tank so not sure if its just bad or not. i have a new vac pump coming so hopefully that will do it. if you have any tips about these vac fuel pumps let me know. can the vac pump be replaced with an electric one?

Well, u got me! Sat right here in my recliner and watched ur stator video and then all 4 of your top end rebuild videos. Once I get my hands on a service manual I will be feeling a lot more confident figuring out any future problems that may arise. Thanks again

They are called “keepers” and it’s easier to use a magnet to retrieve them vs needle nose. Where do you get that manual u use and also where do u buy ur parts? Keep up these great videos

Back in my Honda/Datsun/Nissan mechanic days we would make a wooden I block about 3 or 4 in tall and 1 in thick, one edge of the block is a straight edge and the other edge you cut at an angle matching the more or less V shape of the chain down towards crank. Then just wedge/tap it down between the chain sides and it holds the chain in place w/o it dropping off of crank gear. Also drill a hole in top of the wedge/block to tie a cord so you have a way to retract/pull out the wedge when done. Again, great video

Thx for the reply. I’ve never received a reply to a comment before. On this Honda Helix “clone”, I HAD to replace the worst fuel tank I’ve ever seen ( n filter). Now that I can shoot gas into the carb for a min of running, that vacuum style fuel pump isn’t picking up fuel. Any suggestions?

I Was given a 2005 cf moto freedom 250 with 1100 mi parked since 2010 And no spark. Watched many diagnostic vids but all of the volt reading’s came out wrong. Ur video showed me where the stator and wires are n there I found the no spark problem. MICE!! Those varmits had chewed the wires. After a few hours of wiring repair the spark arrived n it started. Thx so much, ur video saved the day

What wiring harness kit did you buy for it and also is the stator 18 pole stator with the 3 holes ?

Ive found on mine that if you cover that oblong hole at the top of the carb throat, it runs better. Dont know why

Didnt you just say you were out ripping up some dunes b4 you filmed this last part? And now its running like doo doo? I hope you honed your new cylinder cause if not your rings failed to seat and yervring gaps may have lined up causing low compression

I hope you honed out the cyl unless it came from the factory pre honed or else your rings wont seat, eh, EH?? You didnt did you?

Tip: your suppose to hold throttle open when comp testing. Mine reads 150 lbs and i didnt just rebuild mine. Ive got an elec issue

I believe you should have 20 to 30 volts a/c from the three yellow wires coming from stator that go into the inverter that converts it to dc then sends 12v dc into CDI

Mine has 150 psoriasis compression which is why I've decided to not give up on this engine yet. I've gotta get ignition firing n give it another chance

Man you are a lifesaver! Thanks for all your hard work

Is it still working? No issues since?

I sent an email a couple days back, my email address has a tendency to end up in peoples spam folders, cheers, Steve.

I am in the process of fixing this same issue. Dash went crazy then the guage needles wouldn't move from 0, and vehicle would barely run when it did start which was very rare. My OBD2 scan tool would power up but not connect to the cars network. I finally found that the abs module was causing the normal (2.5v) volts on the Canbus network at OBD2 connector pins 6 or 14 when testing to ground was over 8 volts. This in turn caused all kinds of this weird crap. As soon as i unplugged the abs module under the vehicle, near the driver's side frame rail, the vehicle would start and the instrument cluster and nav display would act normal. This took me a serious day to figure this out. This abs module had part of a plastic shield missing that is supposed to deflect water and crap away from it. Hope this helps someone.

Need help. I have the same engine 250cc it’s been running with no oil and it started leaking oil from the head gasket but for some reason it still leaks out. What do you think is wrong. Tia.

Thanks for you kind offer, is there anyway I can send a photo of what I refer to ?

Great video, very helpful because mine was in bits when I did the rebuild, may I ask a question about the water cooling tubes to/from the carburetor, if you can help I send more details about the problem I have.

Why not actually say and show how to fix?? I stopped 2mins in smh

I have a 1978 DT175 as well, I wish your videos came out just few months earlier. I was completely lost on my engine rebuild after some major issues and ended up having to throw in the towel and send it off to a mechanic. I just got it back a few days ago after nearly a year

Your movie deserves it's own quote as the answer "I recall, central park in fall...Have you torn your dress, what a mess..." :)

Hi, I found your video's very helpful so many thanks for that, I brought a buggy with a few parts missing tubes etc, it has the CN250 engine in it, I noticed that theres a small hose connection on the thermostat housing but can't work out where it goes to, there is no expansion tank on my machine so I'm wondering if this small hose may have gone to that, any help appreciated, thanks again.

Hi

Buenas , que significan los dos símbolos que hay ala derecha del cdi

Thank you so much for this!
