The vacuum operated fuel tank vent valves may stick. Opening gas cap will immediately correct your fast idle if that is the problem.

No disassembly required.

I have tested the bike with the gas tank open and the problem continues. So discarded.

According to this link, there are idle adjust screws you can change.

https://www.bike-parts-kymco.uk/kymco-motorcycle/125-SCOOTER/DOWNTOWN/DOWNTOWN_125_I_ABS_EURO_3/CARBURATION/177/8/0/177

According to the service manual, the screws with the reference 16170 cannot be modified, since they control the idle speed and are pre-configured at the factory. In fact, they have a cover that in the exploded view is 16112.

I will upload photo when possible. I will now go to the parking lot a to review what Forero Crossbolt said.

Check twist grip and throttle cable. A little lubricant will not harm anything.

As I already mentioned, this is not because the cable from the grip to the throttle body spring does not get stuck. In fact, I applied some oil to the throttle body spring and now it glides much better, the stopper feels forcefully on the throttle. I have checked where the throttle screw stops on the throttle body and it is clear that it reaches the end of its travel.

What John Said And take your second key and open the gas cap the next time this happens. Do these two things before taking everything apart.

I do not understand this, if there is a possible clog in the gasoline filter, can it cause this type of failure?

Idle control valve or air inlet leak.

Where is the control valve located? About the air leak, I take note.

Downtown 300 / Problem with my Downtown 125 €4 of 2017
« on: January 28, 2021, 06:19:06 PM »
Greetings community! I´m sorry for my bad English.

I have a Kymco Downtown 125 € 4 from 2017, which for a few days has had a problem, and that is that when I slow down to stop, the motorcycle idle (without transmission load), it stays slightly accelerated. That is, when I stop, the bike stays at 2200 RPM's and then progressively drops to 1800, which is its idle. I didn't do it before, so i have made the following checks:

1. Valve adjustment.
2. Check the throttle cable to see if it was stuck in any section of the sheath. Negative result.
3. Check the throttle body spring travel. I have lubricated it lightly with Oil 3 & 1 with the same result. It slides much better than before and the end of the race can be felt strongly.
4. I have reset the TPS and ELP sensors according to the motorcycle workshop manual.
5. I have cleaned the lambda probe with ultrasound. It has been quite good and has released charcoal.
6. I have loosened the engine drive belt and tested the engine idle (no load) and it does the same, it stays accelerated and progressively lowers to idle. The purpose of this is to rule out problems with the variator or with the clutch or pulleys.

The only thing left to do is disassemble the throttle body to see if it has any kind of dirt in the ducts or in the potentiometer.

Say that the filter you have right now is the 300 filter, since I have read that incorporating it improves behavior. The truth is that it does work, but it is a very subtle improvement so I will soon put the one on the 125 again. I imagine that the throttle body has probably gotten dirty or swallowed dust and blocked a duct.

In your experience, what can cause this type of failure?

Might you get some help with your alarm system by speaking with the service desk of your local Kymco dealer?
Also, a 2017 model might still be under warranty (24 months from purchase date) - so caution is important as you know.
Stig

The motorcycle dealership where I bought it does not install alarms, both its own sale and the one that a customer can carry. They tell me they don't do it because they have had many problems with them. I have also searched other agencies and workshops, so I want to exhaust all options before giving up. In addition, it should not be difficult considering that the problem lies in 3 wires: gray, orange and pink. The rest is already located because I have mounted the same alarm on the Kymco like 50, my previous motorcycle.

Hi, I bought a downtown 125 of 2017 and I want to set a steelmate 886 alarm. The question I have is whether the electrical system of a 2014/2015 downtown is the same as a 2017/2018?

Kymco Downtown 2014/15:



Kymco downtown 2017:

I found the electrical diagram of the downtown, but I don't know if it will be the same on both motorcycles. I know that the engine is the same, it is a bit limited by the Euro4 standard in Spain. Being a relatively new motorcycle, I could not find anything about this model online.

I upload the electric scheme of the motorcycle, to see if someone can help me. I know more or less the order of connection of the cables, but I don't know if I can trust the diagram that I have uploaded.

Or if someone can help me to connect this alarm I would appreciate it.

Like 50 2T / Re: Kymco like 50 2S with a Leovince touareg, it´s a possible??

Well, if you can source a SP3 I'd say do it.   I have one on a Derbi, and had one on a Yamaha.  Just barely louder than a stock muffler, and a bit of a power boost.  I think that the SP3 was replaced by the Touring.

You will need to remove the restrictor at the head end for best flow.   You will probably also need lighter weight rollers, and stronger clutch springs.  Sometimes these come with the new aftermarket exhausts, but you will probably need to source them elsewhere.

I understand then, that you recommend me better the SP3 instead of the Touareg? I do not want to touch clutch, right now the drive has some Dr. Pulley. I do not need more power than you already have right now. I just want a little silence.

The Touring should fit.  Their TT will too, but will probably be louder.

As you are in Spain, you could call Leo Vince and verify fitment.  I'm sure the SIP catalog will be of help also.  The Kymco A/C 2T motor has been the same for years, so any exhaust for that motor will mount .   However, the more upswept the muffler, the greater the possibility that it may interfere with the body panel.

I'm betting that if your Turbokit clears the body, the Leo Vince will too.

According to leovince, this type of exhaust is not available for my motorcycle, however, reviewing the exploded view of the powertrain of the Kymco super 8, is almost identical to my engine block, so in theory there should be no problem with my motorcycle .

I have also seen the Leovince SP3, in fact I have even seen it mounted on my bike:

But watching Youtube videos I see that sounds like a tin, obviously it is a subjective appreciation since it is not the same to listen to it through a video than to have it in front of you.

Like 50 2T / Kymco like 50 2S with a Leovince touring, it´s a possible??
« on: March 28, 2019, 11:04:31 AM »
Hello, I have a Kymco Like 50 of 2T, and I want to mount a Leovince Touring escape. I've seen in Youtube videos that this escape is only for the Super 8, which I think has the same Like engine. Right now it has mounted a Turbokit TKR 010:

 and the truth is that the bike is very good if it were not for the noise. It gives headache. This is why I want to mount the Leovince, because I like the sound it has:



My bike is standard, I only changed the rollers for some Dr. Pulley and the exhaust, nothing more. With these 2 changes the bike develops up to 90 Kms opening gas fully. My average speed is 70 limited by road. I do not want more since I do not want to melt the engine either. I do not need it.

Also I want to know what are the symptoms that gives a worn clutch, since I suspect that mine is for the drag. Sorry for my bad English, but I write from Spain.

Greetings to the whole community!
