Thanks Chalieoscar, we hope you can take something from this video, thanks for watching and glad you enjoyed it.🙌 Manual Choke is also a valuable tool in the tuning proces and with fuel diagnostics. Use it as it saves time.
I added some 10W40 to the inlet of the carb and it lubed the choke. Ran the moped around the block twice and it runs well now. I was not able to remove the 2 screws that hold the choke to the carb. Good video, I learned everything I know about auto-chokes from this video.
so does it heat the choke when you turn to the on position? should i wait to crank the scooter for 40 seconds before cranking it? in 40 degree weather. does it get warmer every second key is on? or is that only when its being cranked.
Hello, i have a Piaggio zip 50 and the engine go back to idle at around 30% open, i cleaned everything but the problem is still exist, can it be an auto-choke problem? Can i run it without it if i cover its place with something? today it started but i couldnt rev it up and its just stopped before getting warm, now still cant start it and now the fuel is leaking from somewhere on the carbuerator hope you can give me some advice, thank you.
Thanks for this very informative video! I have a new scooter under 400 km. It seems to run good but before starting it, I usually need to turn the throttle once and start it up. The rpm is only about 1,000 to 1,500 rpm's so I have to baby the throttle a few minutes (or it will stall out) until it starts ideling at around 2,000 to 2,500 rpm's and then it's fine. Do you think it could be the auto choke is not working?? Thank you
Check the choke for sure, also the cary may not be adjusted correctly and also you may have an air leak so check from the airbox to the manifold just to be sure. this should be done from the dealer at the workshop prior to delivery to customer so if you have an issue reach out to the selling Dealer👍
Will it work with any carb? I have a honda Dio AF18 and the E choke has a faulty connection. One of these seems like a perfect replacement, especially for cold starting. Question though? How long do you usually let the choke stay on for the manual one?
Check the air filter, enough air flow? Check the fuel flow when cranking the engine, is the fuel flowing to the carby? Check for spark, is it Zapping Blue/white at least 10mm? Test compression and air leaks.@@Ace01010
If i were to plug the e choke out, the cable that goes to it. Would it be like running the bike completely warmed up but all the time? And also if i were to plug it out when the bike is completely cold and the ignition off would the choke be off and completely down?
It works on temperature and changes position based on the temp of the sensor inside the mechanism. The power adds heat so it can expand to closed position. It does not need power to retract, so we put it in the freezer to speed up the activation process.

Hello, ive got a jetforce 50 with a 70cc malossi kit in, 8g rollers and leo vince clutch springs, uprated carb and a leo vince tt exhaust but i can only get about 45mph out of it, any advice. Thanks
hello, i have a "small" problem. recently i gave my scooter a bit of a makeover, put a new exhaust on, rejet, new rollers and springs. but now when i use the throttle the bike takes a very long time to accelerate, like i have to rev it to above 5k rpm before it even moves a little, and acceleration is just painfully slow. i thought it might have ti do with to stiff clutch springs or something wrong with rollers. on unrelated note there has also been a rattling sound coming from the variator like a screw is loose in there or something. scooter in question is a derbi Atlantis with hiper engine. any help appreciated and cheers💪
@@R_O_B_O_M_A_NSlow acc was from me still having restrictor in the exhaust. Also changed to lighter rollers. The rattle is still there, and is coming from something loose with the kickstarter, most likely the pinion gear. Flat rollers could also be the problem. Easiest way to tell would be to remove the variator cover and start the scooter without it, that way you can see if its kick or vario issue.
Is this for 2 stroke and 4 stroke scooters ? My scooter hard start unless i unplug the inricher then will start. And have problems idle. . it didn't used to do this .
The auto choke system is the same for all types, it is a system which enrichens the fuel supply, the choke may look different but operates under the same principle.
Are these auto chokes generally the same thing? I would like to convert my Peugeot Django 125 to a cable operated manual choke. Do you think yours would fit?
Hey so my Aprilia SR50 starts first kick in the morning and it starts off with high rpms and drops after a few seconds but if I let it idle for 2mins it dies. Also when i start riding the throttle response is poor and sputter before taking off even when its warm. Could it be a choke issue?
Hello! I have an issue with my scooter but it only happens once every 5 rides approximately , so what happens is after about 1min of me riding it sputters and dies . Only way I managed to to start it back on is by closing off the air pipe to the filter and it revs for 5sec before dying down again. I looked basically into everything (air filter, carb,idle mixture,fuel lines , valve adjustment , fuel filter , spark plug ,changed cylinder , checked vacuum lines) only thing I noticed is the air intake hose to the carburetor having a small crack . I had the scooter sitting for abt a month in the sun could it have caused something to go bad in the CDI or this auto choke?
my Gilera DNA 180 starts immediately from fully hot or fully cold but needs a bit of throttle to start up when its hot but been off for a few mins. It fast idles cold, idles like shit for a few seconds then fast idles again gradually settling into its idle. When started from warm but not fully hot it needs little bit of throttle to start, idles rough for a couple sec, fast idles at like 2k rpm for 30 sec or so then back down to set idle. Closed idle mixture screw causes engine to eventually die so ik pilot jet is fine and the throttle response is fantastic. I read that these auto chokes have 'wax capsule' in them which expands with heat to push the plunger out. Can this deteriorate over time and how well protected is it against chemicals like fuel, carb cleaner/non-polar solvents etc. Like the choke obviously works but I dont think its as responsive as it once was (2ndhand unit from ebay as i need OEM) or is sticking a bit. Also I'm actually really surprised at how much electrical shit does actually deteriorate gradually rather than it either works or it doesnt and it seems to be a big thing with 'solenoid' stuff like this.
I just had an opportunity to test the choke on a 2 stroke, the power is AC and put out 4.6 volts. Ignition on no power, it is only powered when the enigne is running. Power supply when the stator rotates.
Hey man! Do you have any idea why my 50cc yamaha scooter runs so good when cold for like 2-4mins and then it starts to lose power and can barely go up a hill and atleast 50% off acceleration speed just disappears. The problem has worsened when summer came
Hello! I've only get 3V from the wiring. Aprillia sr50 2019. New choke = same problem. Anyone know where that 12V is sourced from in the electrical system? I have ordered the manual choke, but would be nice to get the electric choke to work as well
@@namaikativputkata202 i just raise my idle screw so that if it drops rpm, it will still be sufficient and not sound like struggling. I dont have any vacuum lines leaks at all
hi mate i’ve been having problems with my moped recently. so i found out i had a split in my fuel line and i needed to fix that immediately, so i ended up replacing them and since then it started bogging out after half throttle and just seemed like it was struggling. i rode it for a few days after that and on thursday last week i was going home and it just randomly started sounding like a piece of metal in a washing machine, just grinding and jolting and struggling to run. i don’t know what’s wrong with it
@@scooterstreetau it’s hard to tell when it’s coming from since it only happens when i ride, but i think it’s coming from the cvt. i took it apart and noticed who ever owned it last, the plastic variator fan snapped and they never replaced it. it’s a piaggio zip 2t
@@scooterstreetau okay no worries i don’t know if it broke while i was riding it or if was like that a few months ago before i bought it, but what issues could it cause without having it?

You need to eliminate the possible cause. Do this by testing each system, Jet up to 98 and come down from there. Is the needle set to middle. You should only fit 1 part per time and tune to suit to avoid this. It will save dollars and hours of trouble shooting.
yes I did change one part at a time, however the splutter/bog has been pretty consistent. The clip was initially on the leanest top notch so I moved it to the middle which helped somewhat in the mid range but still the same issue from half throttle onwards@@scooterstreetau
Do you have Genuine scooters there? P.G.O is another name for them. I have a 2008 buddy 50. I put a Amazon big bore kit on. Kit was ACTUALLY decent quality for $ I chamfered the inside of ports etc....bike locked up like 10times on way to store & back from running lean. Obviously I have a Massive air leak somewhere correct? Idk how I didn't melt the piston😬😓💯
Yes good addition to the troublesome choke. We remove the choke and have a special connection which connects it directly to a 12v battery, you can visually see the choke extend into the OFF position. Or the freezer to have it retract.

That is fine.
Could my choke be the issue? Basically when cold it stalls when no throttle input and it runs very rich when cold, once warmed up it runs perfect
Yes it may be. Check and test it as in the video.

Start by checking the carby and the fuel tap.
Cover half the air intake with tape or something
Is it ok to drive with the choke plugged out? The cable that goes to it. Would it harm the scooter in any way?
Will be no problem.
