Hey yall,
I am experiencing a little hop when I try to throttle the scooter at a complete stop. It didn't use to hop before only started this week.
Scooter Details:
- Kymco Agility 125 [Correcting]
- Done 16000kms so far. Last service was done at 13500kms.
Any suggestions?
Many thanks in advance
CHEERS :)

You mean it jumps off the line too aggressively? If yes check your clutch fly springs.
May as well check over the whole cvt system too if your in there anyway. Check belt, clutch pad condition, variator, rollers Give it all a good clean up etc. Belt dust etc and general wear and tear of cvt can cause all sorts of issues. I would def check clutch springs 1st tho or just replace them if theyre old anyway since they prob need done if you havent did them for a while.

Hi Streido, thanks for the quick response. Yes, it jumps off the line a little bit. Man, I have no idea how to open the bike up or check the clutch springs, etc? Does this mean I am better off taking it in for another service? I remember the mechanic telling me before "The belt normally last up to 15000-20000kms". I have been consistent with a service at every 4500kms.
I appreciate your help.

If you were planning to have the belt changed professionally , that would be in the same area and be a good time to change your clutch springs . I had my roller weights , and clutch weights , which contain the clutch plates replaced at the same time . That way all of the normal wear items have been redone . Good luck .
-
Cool! At least I know what to expect now. Thanks. Time for the professionals to get dirty with my bike ;)

I really think a full proper service should have covered the clutch springs, maybe not tho. Maybe call and act as a new customer looking for a service and ask what their service will include? Maybe they just checked your belt, air filter and rollers and swapped out the oils?
My stock belt lasted 8000-9000km before it was at its service limit of 16.5mm wide (17.7mm or 18mm is new). I still kept my old belt as a back up emergency belt. If your old springs were worn and loose then perhaps they have swapped the springs and thats why it now feels more "jumpy" off the line? Its not something to try yourself if your not too mech minded or used to servicing working on things yourself. Its not too hard to do yourself if you have the tools tho and want to try it?
The spring stiffness controls when your clutch will engage, stiffer and the rpms go higher till it lets the clutch pads grip to give better take off. Softer springs give a less aggressive slower take off. It def sounds to me like something is amiss in the clutch, either with the springs, or the clutch itself, could just be belt dust and grime in it tho too. Without seeing it its hard to pinpoint exactly. Must be something in the transmission needing cleaned up, replaced or repaired i would say tho. Shouldnt be anything too expensive or serious. Sometimes these things sort themselves out or just go away themselves, gremlins messing with your scoot :D
Keep us posted how you get on if you get it sorted out. My money is def on something in the clutch needing attention.

Btw those belt widths are for my Agility your size is prob different.

This is awesome! I am learning a lot here :). I have the same scooter '09' Kymco Agility 125cc, Red Color: http://www.kymcousa.com/showroom/scooters/agility125/index.html. (http://www.kymcousa.com/showroom/scooters/agility125/index.html.) I will take it in to the mechanic and definitely find out. Will post back soon.
-
Mine is only a 50cc Agility..........
I just ride it like its a 125cc ;D
Good luck, hope its a quick and easy (cheap) fix :)
-
I'm back. Yea its gonna cost over $350 for a new belt, cable, etc :(. Didn't expect this but it had to be done for a scooter.
Thanks guys.
-
Wtf ??? Seems awfully expensive?
Guess thats why most of us do our own work now instead of paying the man.

True that parts are even geting expensive as scoots are geting back on the road again.
its been years sense I seen so many back on the road.
-
Still even then its still expensive.
I got quoted £45 for a new belt the other week locally from a dealer, found the exact same one online for £15 delivered, just shows the dealers mark up is WAY too high. Same with carb jets and even spark plugs, all around 3x higher from the official Kymco dealer, hence why i dont use tjem unless its an emergency or i cant source the part elsewhere.
I know they have overheads etc that online store dont have but the belt i got online was from a place that also has a physical shop too ao if they can sell for £12 + £3 delivery why cant Kymco dealers sell for the same ???

Hey guys, I just got my bike out of the workshop. Kind of disappointing. My bike is still kind making a little jump but not as heavy as the first time. I asked for the belt and seems like nothing was wrong with it, hard to tell maybe to a professional it looks differently. Anyway, I'm pretty eager to learn how to fix myself.
How often do you have to change the oil? But the oil wouldn't make it jump, will it? The oil was change the last time I got it service about 3Ks ago.
Thanks for help again :)
-
The oil won't make it jump. Just follow the manual with regards to oil change intervals.
Jumps may be caused by a glazed clutch. What they do is sand the surface of the clutch to remove glaze.
I had jumps before but since I don't have the time to dismantle things, I just ignored it and rode. No more jumps now. Maybe a few hard accelerations may cure some small jumps.

What!! Are you saying I could of left it and would of been fine? Oh well, you learn new things everyday lol. You know whats funny, looking at the belt again, it seems like nothing is wrong with it eh. Should I post a pic of it here? Oh well, what's done is done. At least I can leave it the next time it happens again.
Too easy, thanks for the useful info again guys.
CHEERS :)

I'm saying that the oil (engine oil and gear oil) has nothing to do with the "jump".
I had some "jumps" since last week. I opened the cvt cover yesterday, sprayed some brake clean,
jumps disappeared.
-
I had a feeling it didn't but wanted to take a guess ;). If I knew how to open the bike then maybe I can find out what the CVT cover look like and grab me a hold of a brake clean.
You wouldn't happen to know what kind of brake clean I should buy e.g. brand? Is that like using CRC?
-
..i'd stay away from that service center...
..people spend a lot of money trying to get that jump off th line!!...
:o
..What!! Are you saying I could of left it and would of been fine?
....probably....
-
..this is, more or less, what your clutch looks like...
..click on image for larger view...
-
..heres a complete set of cvt components...
-
..that long black caseing is the cvt cover...
-
..oops..i just noticed there is no "drive boss" in that cvt component pic...
..the boss is the steel sleeve that goes on the shaft, through the "variator", at the small end of the belt...
-
..here's an "exploded" clutch..
..the 3 pads are around the perimeter....
-
..you will ever fare much better by doing your own maintenance and upgrades...
-
WOW :o !! Thanks for the pics wordslinger. True that. Damn, I should of kept my old bike to take it apart for some experience. Interesting! I never thought about upgrades on my bike. Worth baring in mind ;).
Thanks again.
-
..quite welcome buck!
..all mine are 50cc, but you can easily tweak your 125 cvt for another 10mph, and quicker take-off as well!!...
peace
