I am thankful for this video. I have this, 2020 with 18 miles. Ran great nowstart and stop. Got out the ethanol and put in free. New carb, plug, checked valves. Thinking CDI. Even tried a new petcock. You got any ideas? Im dumbfounded at only 18 miles. I have moved on to a 2013 Kymco 50 2T. Much happier. Love the bigger tires.
Hi, thank you for the informative video! My 50cc was fine but lately lost power at start, still have the top speed but at start is slower than before, I have to give it a full throttle to accelerate, any idea what the problem might be? Thank you!
Great vid. Very helpful. One suggetfor future vids-when trying to show a dark engine compartment, always have an LED panel or shop light,flashlight to brighten it up. That helps your audience. Cheers
What headlight bulb would you recommend for an X-Pro 50cc scoot? The one it came with is an LED, but it's dim as heck, it'll illuminate the reflective housing all day long, but barely lights the road in front of me. The owner's manual doesn't specify the type of bulb it is either.
@@MOTORSUncut Well, it's not so much an issue, the bulb just seems not as bright as it could be, it's an LED bulb, I'm just not sure which bulb socket it uses without taking it out.
@scooteratvsales, I have the Vitacci spark and one my front turn signals has partially went out. The top two diodes are completely out . The rest is fine . Any idea how to fix this? If so please do a video . Thanks, you guys are awesome
Not planning to do a video on that topic anytime soon. The front nose face panel has to be removed very carefully. You will find screws that have to be removed below the head set and tabs slowly disengaged to remove the panel. Study the project carefully, take your time and you will be able to remove the panel.
My scooter has EFI. After 7 years, minor shaking on acceleration from stop. Replaced flyballs and cleaned clutch surfaces. Total cost $8. I live in the Philippines. Including mechanics fees.
My NEOS 2015 start to misfire and wont go on wet roads! Any idea? How do I remove the floor panel to get to the coil?? I cannot find any description! Ps. have changed the plug cap.
Mine works fine in cool weather, but once it gets in the 60s F and/or more humid, she's slow off the line and doesn't seem to reach the higher rpm range. Oh, also less fuel efficient than should be expected (it's completely stock from the dealer) so I'm leaning to air/fuel mixture at higher temps, maybe the dealer richened it up to make it run good in cool weather (I bought it in November) but it's too rich when it warms up. Any ideas?
my scooter bogs down, when my air intake is wide open, so no risticktion. when i ristrickt the airflow then he runs better, to almost fine, do you have any sugestion,
I have an 08 2t zuma sat 2 weeks w oremium in it always had hot start problems (i gave it a lil gas ans she cranked up b w no throttle no start snd now after sitting empty cause i ran the bike till it ran dry but now it wouldnt idle now it does i turned rhe idle up my bike started to run so so so good after it did 0-30 in like 2.5 seconds now it wont do more than 35 and once it bogged out on me
50cc scooters already come with a built in fuel screen inside the tank that attaches to the petcock. The filter between the carburetor and the tank is practically useless
Aye would appreciate any advice but i have a 49cc bentelli and it started losing power and tops out about 20 instead of 37 now and sometimes if it turns off i have to wait awhile for me to be able to start it again!
Hey, thats a great video. Could you please help me with my scooter issue. So my 50cc scooter bogs down over bumps or holes in the ground or an uneven surface while going with speed above 15-30km/h, depending on the bump or hole (when i say hole its not typical hole so even tram rails do the same). And what happens is that the yellow light of the engine goes on and wont go off or let me accelerate until i reach speed of 10km/h or less, which is very annoying and when in traffic is even more annoying. I did notice that if i let off the acceleration before the bumps it usually is fine and does do it, but when going over tram rails which have a very sharp drop to them (although not a high drop, its about an inch or two) it still does the same thing even in low speed and is very frustrating. When i removed the seat to check on the carb, i didnt notice anything out of place, everything seems to be alright and after giving it much thought my personal conclusion is that this must have something to do with the "head" of the electronic injection system that the scooter has. So juat for information its a Senzo Riva lux 50cc vespa like chinese made scooter and i bought it off from someone else who failed to mention this, but it might be due to the fact they havent been driving it for almost a year. (I know that because the batery wslas dead and we had to charge it for the test drive, but i didnt notice any problems when tested it since there was no significant bumps or tram rails to go over. It would be of great help if you could help pinpoint the issue. So over bumps(like uneven road or brick path with bulging spots) at speeds of 30-35km/h (thats the limit) the engine lights goes on, does not accelerate at all (upon attempt it bogs down), and after dropping to 5-10km/h engine light goes off and acceleration works again. Now i would have gone to the mechanic but they said they charge just 50€ to only take a look and its not even sure they will find out the problem, so 50€ is the base plus them fixing the issue (if they find it) will cost additional money up to 300€ which to be honest at the moment i cant afford and is a bit too much. Ijust bought a car for my work and the scooter is used for my second job of doing food delivery and i cant have this issue if i want to drive normally. Please let me know if there is anything that comes to mind with my issue and if there is a solution for me without the need to visit the mechanic at this moment. Thank you in advance and hope to see your response.
Check your brake safety switch, wires may be backwards. Do you hold your brakes when you start your bike? If not try holding your brakes and see if it starts, if it it doesn’t start your wires are backwards. If they start without holding the brakes then yes switch those brake safety switch wires around
@@MOTORSUncut i was thinking if could be the carburetor that is dirty and needs to be cleaned. Or the new cdi that’s burnt. I also thought it could be the fuel filter tjays clogged up
@@goedkjdjdI’ve got exact same bike with de restriction too and it bogs out pretty often, the best thing for me is just to gain speed slowly when pulling off and it don’t kick out , also letting go of the throttle before hitting bumps or potholes
ive replaced carb spark plug coil cdi vacum lines fuel filter still bogs down uphill or somtimes bogs down almost shuts off starts up fine idles good.should i check rockers
@@MOTORSUncut well a couple of weeks ago i was driving a long distance and then suddenly a ticking noise became apparent, so i think the rollers are flat
Lets see if this video helps. I am desperate. I took my scooter in to get looked at it wouldnt start, randomly bogged down, and had fender tire rub. I asked for the inner rear fender to be replaced... The battery was fully charged when I brought it in.... and I got it back not starting so I swapped battery and it worked.. they claimed they "fixed" that tho but I dont see anything they did to it.. They charged me $103 and made me wait 3 weeks... and thats after I told them just give it back I am tired of waiting. I swapped out the carb and nothing.. air filter.. cdi, fuel line, petcock, and nothing makes it work right. I struggle to get to 15 mph.. but then other times it will get to 40 mph.. even down hill I dont gain speed.. this is my daily vehicle to work..
@@MOTORSUncut So I know when I got my scooter it was doing 30-45 pretty easily on flat ground. Now, I struggle to hit 25 mph and at times will bog down to 10-15 mph or worse. Vacume lines, Fuel lines, carb, cdi all replaced. I did puncture my tire 6 days after I got it so I had to put a new tire on it was still fine then. Tire pressure in front and back good. Sometimes giving it any gas just bogs it down and shuts off. Idling it doesnt want to stay idling (most of the time) some times it will idle so high reved that it wants to pull forward with no throttle. Have tried tuning it, and nothing helped. I do need to check spark plugs because at this point the only thing I have not really replaced is the motor itself.. and I am only at 2,500 miles on it. It's really frustrating me. I do hear a little tink rattle type noise sometimes from the CVT area. I did find something that looked like gray-ish water in the air box.. perhaps it was fuel or water or something. No leaks on hoses. And what really makes me mad is like some days it will run good for a while then shit the rest of the day. Other times its just shit all around. I mean literally I got passed by another person on a scooter as if I was standing still yesterday and it was just another 50cc.. I miss my Tao Tao at least it's problems fixed easily. This Yongfu Denali 50cc does way better starting up but this problem that cant be fixed is really buggin me.. I really hope it's spark plug because theres not much external to the engine left for me to look at.. the spark plug looked fine not black, not grey it looked pretty clean. I would pay a lot of money just to know wtf is making this do this to be honest lol No shops can look at it right now in my area its 1+ month wait minimum. And places that do work on them are closed sundays and mondays and half days on saturdays so they do not even work a 40 hour week even.. which sucks.
You might need a valve adjustment or maybe you have a vacuum leak somewhere which can be very hard to find or your air intake might not have been installed properly which can cause an air leak somewhere in the air box. Even the smallest air leak can cause the bogging down issue. Maybe a bad gas cap can be preventing fuel from flowing. Hope this helps.
You solved our issues, much thanks! 👍
Glad I can help

The X-Pro brand that is sold on Amazon is a value level scooter. I am not familiar with this brands issues

whats your opinion on running high quality gasoline in a scooter?
i heard its way better due to Ethanol destroying old scooter gas lines
Recommend using 91 Octane
How much money would it cost me to take my scooter in for the first 200 Mille checkup?

Hi, my 50cc scooter just shuts down when on full throttle, and cannot be restarted, any idea what to check?
It works ok on idle...
Not knowing what brand, model condition, check the carburetor jetting.

Recommendation, Carb. swap would be an inexpensive potential fix. go from there.
my scooter bogs down, when my air intake is wide open, so no risticktion.

Hi I have a lexmoto echo 50cc and it starts up but it doesn’t speed up and when I break the engine turns off do you know what that could be

Check your brake safety switch, wires may be backwards. Do you hold your brakes when you start your bike? If not try holding your brakes and see if it starts, if it it doesn’t start your wires are backwards. If they start without holding the brakes then yes switch those brake safety switch wires around
These rubber intakes cracks easily.Use brake cleaner to find a leak.Cdi can be bad too.

Vaccum, Spark, Jetting on the carb.
so basically just repace the carburator
