Agility 125 / Re: Agility 125 R16 bogs down and dies if going over 65-70km/h (40mph)
« on: August 03, 2023, 07:10:42 PM »Jeeves your issue sounds like what I had wrong had with my scooter, turns out it for me the fix was the CDI. It failed with less than 2000km. Upgraded to a performance unit and have replaced voltage regulator and still going strong.
Sorry, I completely forgot that I never closed this thread.
The problem was the fuel pump. Bought a generic GY6 pump and haven't had the issues since.
The GY6 pump inlet and outlet are on a different place compared to the original, but it can fit.

Agility 125 / Re: Loss of Power, Stall After Bumps
« on: August 03, 2023, 05:46:06 PM »Yes the plug needed to be replaced.Interesting.
Do you have a picture of one of them?
Iridium plug tips never deteriorate, the ground electrode wears out, but that takes a lot of km.

Agility 125 / Re: Loss of Power, Stall After Bumps
« on: August 02, 2023, 04:52:09 PM »Hey All, I'm embarrassed to say I think the problem was due to a spark plug needing to be replaced and its cap was knocked a little loose.
I usually replace the Iridium plug each spring after putting about 8k km on it a year. This spring I read that the plug can go something like 60k km before needing to be replaced so I didn't replace it. Does anybody else go through plugs like this?
Iridium plugs last much longer then regular plugs. Had an Denso Iriduim on my scoot for over 30000km, on my motorcycle (NGK Iriduim) they lasted over 50000km.
Changing it every 8k km is just a waste.

General Discussion / Metzeler Roadtec Scooter tires
« on: July 27, 2023, 05:45:10 PM »
Couldn't find much about them online, but I have had a few sets of Metzelers on my motorcycle, and they were good tires, so I ordered a set last September.
Before I had 2 sets of Michelin City Grips.
Each set of Michelin's lasted 20000km, and they were OK, but honestly I wasn't very satisfied with them after a while.
Both front tires got a terrible wobble, and riding on wet was just plain bad.
So far I have around 5500km on these Metzelers and they are very, very good. No front tire wobble and I can actually lean in corners when its wet.
They were the most expensive set of tires for my scooter (Agility City 125), but don't regret paying extra for them.

Agility 125 / Re: Link for correct gear oil? 2008 125cc
« on: July 26, 2023, 06:17:54 AM »Is that 180ml of SAE 90 gear oil to drain and refill....or following a rebuild?
Stig
180ml for drain and refill

LIKE 200i / Re: Low power when running - goes out in idle
« on: July 03, 2023, 06:17:26 AM »I would as a first measure, put a transparent fuel filter in this line between pump and injector.
To check your pump pressure, go to a car shop and they should plug it into an SunTester or similar.
Or buy/take a cheap manometer. Output should be around 3 bar of delivered fuel pressure
For electrics on your pump:
-ignition on- battery current on your pump (multitester) either it runs or not, don't think less voltage makes a huge difference there
.
Won't the fuel pressure be an issue with a plastic transparent fuel filter that is usually used for carburetor engines?

Super 8 150 / Re: Super 8 150 2014 Won't Stay Running
« on: September 18, 2022, 07:04:37 AM »She starts, idles fine, runs fine. Will run 50 mph for a hour to 4 hours then suddenly she will start dying out, and cut off completely. She then will crank but not start, and after a day or so will start up just fine like nothing happened then the cycle continues. Any advice?
Check for spark when it happens again. Could be something wrong with ignition.
Also check if fuel getting to the carb.

Agility 125 / Re: Gear oil replacement questions
« on: September 18, 2022, 06:11:28 AM »You think so? Doesn't the manual say 4k?
There are a few gears inside an enclosed casing bathing in gear oil transferring less then 10hp to the rear wheel.
Every car that I have had has gone more then 150000km. All manual transmissions. The gear oil has never been changed in any of them.
Kinda makes you think.

Agility 125 / Re: Exhaust catalyst (Agility 125 (2006))
« on: September 10, 2022, 02:22:28 PM »The point is that
the catalyst rattles inside the exhaust
but, i don't want to cut the exhaust cover.
I think so.
I want to fix it from the outside with a screw
I weld a nut to the outside of the casing and
I fasten the catalyst inwards with a long screw
without disassembly and re-welding
so i should know exactly where it is located.
So far, I haven’t found an original factory exhaust exploded section drawing anywhere.
Late reply.
Can't do anything on the original muffler without cutting it open.
The thing rattling is probably not the catalytic converter, but a C shaped pipe that makes a 180 degree turn inside towards the converter.
Happened to me, had to get it cut open and welded again.
A long time ago there was a picture on this forum showing a cut Agility muffler. Maybe it's still here somewhere.

Agility 125 / Re: Gear oil replacement questions
« on: September 10, 2022, 02:15:18 PM »I have a Kymco Agility 125 with 3,000 km and I've changed the gear oil a few times now. I'm new to bikes, but I've worked on many cars before. The manual says to put something like 180cc in after you drain, but I've just been adding an equivalent of what comes out by comparing two clear cups side by side, because not even close to 180cc comes out and I wanted to avoid overfilling it.
Here's my question, should I be adding 180cc, regardless of how much comes out, because gear oil burns up and that's why they want more to go in, or will adding more than what drains every time just overfill it eventually. Like I said, I'm new to this, so any advice is welcomed.
Why have you changed your gear oil a few times in 3000km?!
I do it every 6000km, and even that is a bit overkill.

Agility 125 / Re: Agility 125 R16 bogs down and dies if going over 65-70km/h (40mph)
« on: May 28, 2021, 02:00:32 PM »I vote for vacuum vent valve being stuck shut. To rule in or out just pop the gas cap next time it happens. That's it if it starts fairly quickly. If it doesn't then either the fuel valve or CDI. Scooterfan in South Africa has several posts about dying CDI that have similar symptoms.I had a faulty CDI, but the symptoms were different then what is happening now.
It keeps going at lower speeds, give it more revs and it starts acting up.

« on: May 28, 2021, 01:56:38 PM »how old and how many KM on your scooter? It seems you've ruled out fueling problems..maybe CDI or something else electrical?
The answer may be in why it needs to sit for 10 minutes before it will start again...
2008, 68000km.
Replaced the CDI 2 years ago with a second hand one. Getting spark when cranking.

Agility 125 / Agility 125 R16 bogs down and dies if going over 65-70km/h (40mph)
« on: May 28, 2021, 08:17:46 AM »
The scoot died on me while going to work the other day. Ran fine, no hiccups or anything like that, and a few km before going to work it started bogging down and shut off. Couldn't start it, a colleague passing by picked me up.
Came back to the scoot after work, it started and got me home without a problem.
The next day same thing happened after about 10km. Parked it, let it sit for about 10 minutes. it started and got me home without a problem.
So after that I checked the intake for air leaks - none.
- changed the vacuum tubes
- did a valve check (it was OK)
- took the carburetor out, looks ok inside, cleaned it out using carb cleaner, jets clean, diaphragm is ok, main jet needle is in place.
- changed the fuel line from vacuum fuel valve to carb.
- disconnected fuel hose from vacuum fuel valve and put a piece of fuel line on the vaccum line, sucked on it, fuel flow into a plastic container was good.
Put everything back together, went for a ride, it shut down in 5km.
Let it sit, again, for 10 minutes, it stared up, and if I keep it under 65-70km its OK
Short speeds above that speed is OK, but not for long.
Acceleration is slugish compared to before this started.
I keep thinking its a fuel problem, but what to do?
Fuel filter looks clean and no visible leaks anywhere in the fuel delivery system.
Float needle problem? The float looks and operates OK, float needle goes up and down with float.
Vacuum fuel valve for some reason not keeping up when the scoot needs more fuel?
