Hi everybody i m From italy and i m sorry for my English ;D
I bough a used kymco agility city 50 2008, i changed the drive boss and main jet, i cut the wire in The cdi, i also tryed to cut the cdi but i still going only 45 km/h, and when it reaches the top speed if i release a bit The power he Goes a little more, in my opinion is a cdi problem what do you think? The scooter run 22000km with restrictions, maybe is that the problem?
Thank You!!!
-
There is no wire to cut.just the cdi.you may wana try 5.5 rollers.
-
Also try lowering or bring the needle up in the carb.
-
Agreed to both responses. The jetting is wrong, and the needle Might fix that. Rollers will help all around.
-
Try #82 jet.
-
Hi guys Thank You for reply, i changed the original main jet i mount a 82 now, the cdi is cut but maybe i cut not so much, i post a picture, the roller is new and They are 6g, i Read in another post that a member changed the variator with this one, maybe is that the problem?
What do you think about racing cdi?
Thank You Very Very much

up: I've just tryed to cut more the cdi, I'm sure that I cut the wire inside that, now the scooter reach 55 km/h and downhill I don't feel any restriction, but there's another problem, it seems that have only one gear, from 0 to 40km/h it goes at very low rpm, and from 40 to 55 it goes better, could you tell me why? before cutting it goes always at high rpm and the accelleration was better, why? Thanks again

The CDI should not/could not change the low end gearing.
You simply never noticed before how bad it was.
To fix that install a new Control spring in the rear pulleys. Malossi Red spring if you are close to 200lbs, and Malossi Purple if you are closer to 150lbs.
This will keep the bike in a lower "gear" longer, and give you better take off.
Yes the after market CDI's do give you better performance. I have compared them side by side, and the gain is worth it.
Here's on I found for 7 bucks... or thirty billion lire! http://www.ebay.com/itm/GY6-DC-CDI-BOX-50cc-150cc-250cc-MOPED-SCOOTER-ATV-4-2-PINS-CHINESE-/121441208299?pt=Motorcycles_Parts_Accessories&hash=item1c4675c7eb&vxp=mtr (http://www.ebay.com/itm/GY6-DC-CDI-BOX-50cc-150cc-250cc-MOPED-SCOOTER-ATV-4-2-PINS-CHINESE-/121441208299?pt=Motorcycles_Parts_Accessories&hash=item1c4675c7eb&vxp=mtr)

You could try a open air filter. But becarefull doing that.
-
Thank You guys for replyes, zombie i think you're right but before cutting the cdi take off and changing gears was good maybe i have only to change cdi? The one you posted is different from my cdi, i have 5 pin not 4+2, and yes the price is great but from china to italy is 40 days shipping, not very good :(
What do you think about this variator? How much more speed will i take?

That Var is junk. The rollers are worse.
I've torn thru them in a few hundred miles. Spend about a hundred bucks, and get a Malossi/Polini/ or a Jasil top racing.
Any of those will last several thousand miles. Same for the rollers. Get any of those three brands.
Look on the bottom left side of your engine case. There will be a stamped in part number It will say either qmb 139 or
-
thanks zombie, i'll think about that, I' ve just bough a used original cdi, i hope it will solve my main problem, as you said I should not cut the cdi, maybe I broke that, tomorrow they ship it and maybe friday i'll try it, stay tuned friends!! ;) ;)

Cool beans.
I had to run mid sentence before. I was asking about the engine ID cause you should have the DC cdi. I just saw you have an '08 so the CDI should get cut. The issue (i think) is you cut from the wrong side. You should cut from the epoxy side at a 45 degree angle just until the blade hits the bottom case. 99% of the time that is as far as you need to go. It is possible you cut into the circuit board. I don't know.
I also thought you had the 2013 bike till I looked again... Double check the engine ID so we are positive what you have. There have been several bikes of that vintage that showed up here w/ replacement engines, and that will be the QMB engine, and NOT the Kymco S series. Double check...
-
this is the number printed on my cdi, i hope this will help us: 30410-LEJ2-E10 2008.JUL
If the right way to derestrict is cutting it, could you show me which is the right side to cut and how much do i have to cut? thanks again

hi zombie i'm sorry but i didn't understand well your previous message, i've already bough a new cdi, today i tryed it, it goes a bit better, but it goes at 50 kmh (2 on the bike) after maybe 20 minutes with engine on, i think is too much also in winter, or not? here in venice we have 10° celsius, not so cool...
Anyway, i tryed to disassembly (is right disassembly? or dismount? ;D ) the variator, I'm posting some pictures of that, maybe i got wrong when i change rollers and belt
First problem: after disassembly the carter this piece has fallen, do you know what is? I didn't see from where it fell

Next step, i see this all mounted

this the situation after removing first part of variator

it it right the belt over the drive boss? and is mounted on the correct side? with "teeth" against the drive boss?
This the variator open, are the rollers mounted well?

this is the belt with the serial number, is correct for my scooter?

finally, the rollers are 13x16x6.5g, if i go alone the accelleration is obviously better but really not so much, it was better before changing rollers, but i ask the seller the original rollers, i don't understand why i have this big difference, I hope that I did something wrong :'( :'(
Thank you again zombie!!

Three beers, and 1/2 a nuther thing...
Carter I guess means Carburetor... That piece I am guessing is rubber? No idea what it is or where it goes. It does look worn off at the bottom end...
Don't worry about that for now.
Your Var is worn out. All the grooves on the surface tell that.
Get a malossi or Polini var, and rollers. 5.5 gram with a RED Malossi spring if you are 200 lbs. Purple if you are 150 lbs.
It will cost you around 100.00 USD if you go retail or 50ish if you open a dealer account somewhere.
The belt is correct. It MUST be 16mm wide (at least ) to be in good shape.18mm is new.
The teeth are on the correct side.
The belt is NOT going all the way to the top of the Var tho. I think your pulleys may be sticking part way closed or the rollers are too light.
Take the pulleys off the back, and dis-assemble them. Grease the parts LIGHTLY, and put it all back together. (to be sure it is working)
5.5 rollers, and a Malossi spring after all that. You will get 40-45 mph.
-
hi zombie thanks for reply, the carter is the "cover" of trasmission system, the black iron piece that cover variator belt cluth ecc. anyway, thanks for the help maybe i'll change the variator but why untill i changed the rollers it was good (poor yes but better than now) and now it seems died? maybe the rollers too heavy? yes maybe but why the seller gave me that one if I asked him the original ones? Today I'll try to change them with the old ones, and try again.
Another question, my agility has 25000km (all with restrictions), is a good idea for you invest so much money? Maybe 5-10000km and the engine will die, or anyway if a new engine can reach 40-45mph what my old engine can do?
and the spring what is? I don't know i'm sorry ;D
another thing, i don't understand this part
The belt is NOT going all the way to the top of the Var tho. I think your pulleys may be sticking part way closed or the rollers are too light.
Take the pulleys off the back, and dis-assemble them. Grease the parts LIGHTLY, and put it all back together. (to be sure it is working)
what i have to do? disassembly the clutch? where can i find these pulleys? and what do you mean for "The belt is NOT going all the way to the top of the Var tho"
Thank you thank you thank you
UPDATE: I' ve just put the rollers on the balance (kitchen balance, but just to try):
old rollers= 24g all together
new rollers= 39g all together
I think this is the problem yes? For the variator, do you know if there is a cheaper (but good) one? In italy about 60€ for a malossi and the same for a polini
I'm sorry again but you can reply only once a day so i try to ask you all my doubts, thank you thank you again!!

Here is a video for the Control spring in the clutch.
You should also check if the belt can get all the way down inside the rear pulleys. You will find them behind the clutch.

This is how your cvt works...
https://www.youtube.com/watch?v=jffePCHt11A (https://www.youtube.com/watch?v=jffePCHt11A)
The belt goes further up the variator as rpm is increased (due to the weights in the Var.
Your's are too heavy, and that is what slowed you down.
The 24 gram were most likely 30 gram total new. so it would have been 5 gram rollers.
You really can't get a good Var cheap. Open a dealer account w/ Racing Planet in Germany. It will end up coating about 1/2 of what you found.
If every moving part in your engine broke today, all the parts are cheap. A cylinder/head/piston is under 40.00 bucks, and a crank/bearings is under 30.00.
It's worth a few bucks to keep it running. You could always get 400.00 for any running scooter.
-
wow.... notreally easy disassembly the clutch... maybe is better changing only rollers and try again, but how can i open a dealer account in racing planet? There is only the customer account, and anyway it says to fill the company fields if you are a dealer, and i haven't any company! How can i do? malossi multivar is 65€, i found it for 50 in ebay, they have also naraku var, a bit cheaper, is it good in your opinion?
THANKS
-
Naraku is cheap china crap.
Just make up a company name for racing Planet "Joes Bikes" It really does not matter.
Use your Social number or even your library card number for the VAT. As long as you pay your tax at the time of purchase it is a non issue. They don't care. They are making money.
Just changing the rollers will make all the difference in the world.
