Undesided what I may need for my scoot its eather the clutch spring or the belt both are less then 2 years old. took the belt off and with it measures out to be about 12.5 inchs long when stretched out.seams to be a little long but not to sure.my scoot well only get up to 20 km so it eather the belt or the spring the reast of the clutch looks ok. cash is tight right now so I realy need to know were to start. I would love to get both but unless I rob a bank that well not happen. is there a way of testing the spring. this is what my scoot is doing when scoot is on kick stand it runns fine when off and me on it it starts of fine then slows right down to 20 km and stays there sometimes slower . thanks for any help I can get.
-
The belt is measured in mm not inches. It should be replaced if it is more than 1 year old. They don't stretch enough to cause what you describe but they do get thin enough to reduce speed. This will NOT happen all of a sudden. more of a gradual loss. The contra spring can be tested on a bathroom scale. The stock spring should take 55-65 pounds to compress until the coils touch. Try a compression test (cylinder). My guess is you lost a valve seat or something similar. Also take a close look at the intake manifold. It is rubber ended,(at the carb) and prone to cracking. Have you looked at the Var?

My manifold split where the clamp goes around it to hold it to the carb. Think i had overtightened it and it cut into the rubber. It is hard to see sometimes as mine split underneath so i didnt see it till i took it off. I did have similair symptoms tho, i could only get to 30mph.
-
thanks I hopeing thats all it is. thats a easy fix.

thanks I hopeing thats all it is. thats a easy fix.
Well when mine went i had trouble getting it to idle too. Everytime i set it on the stand then reved it up it went haywire and needed set again. Spent ages turning my idle uo then back down before i finally took it apart and saw the split. Tried gluing it back up and taping over it with rubber tape but it only lasted a week like that while i waited till i got a new manifold delivered. Wouldnt have lasted much longer cos when i took it off i saw it was about to come apart again. New manifold was cheaper than my last belt tho so wasnt an expensive fix.
Might be something else tho. Take it you checked your fuel filter is clean?
-
right now im not in a big hury to fix so I well just look over the whole scoot and fix the easy stuff and hope I dont find any major fixes. this wear I say my scotter preyer.
-
I just posted on Blues other thread. The manifold issues you guys have had is an easy fix. Take the OLD/SPLIT manifold, and put it in a steel pail w/ some gas or acetone. I prefer acetone. About a quarter cup full. FUN TIME light it on fire. It will burn away the rubber casing leaving you with an all aluminum manifold pipe. You can now use any standard fuel proof coupler hose. You will need to use some elbow grease to peel it off but the fire hardens the rubber making it break vs. bend.
-
im saying easy fix because I have extra scooter parts laying around the man cave.I safe all parts from other scoots because you never know. I have a few carbs I just might be able to make one good one with too.

Make a dual carb set...or maybe something in a juicy Turbo?http://www.youtube.com/watch?v=TylF6_xalIw

..i do have that blown air induction setup...hmmmmm....
I herd of people doing that my friend took a coumpter fan and hooked it up to the air intake somehow he says it works ok.
-
Here are a few picts of the manifold w/ the rubber removed, and one w/ a coupler used after.
-
Since I'm posting picts. Here's the Verucci. Gonna be a ruckus.
-
OK now your teasing me .thats something this red neck would do.lol

Fir reel !

Fir reel !
ya fir reel... from the looks of your pic you are off to a good start.just need to find away to weld a seat to it.
-
I am a boat builder. A seat will be a walk in the park. That is the 139QMB that I installed the 50mm BBK on a few weeks ago. 53mph on 10" wheels. I'll be wearing the mattress soon.
-
put a seat like this on that would take much and you can sit low in it.
-
Actually that style is what I had in mind. I already lowered the scoot 1 1/2" front, and rear. I have a welder buddy coming Thurs to do some work on another project so I am going to lengthen it 4 1/2". Get that Vato Loco look going. The frame is done in Awl Grip oyster white, so I figure black for the bolt on's. Twin head lights, brake, and blinkers. That is all I need. Can't decide between turned down drag bars or ape hangers yet tho.

what kind of front end are you going with. and for a gas tank a small keg would look sweet.
-
Never thought about the tank. Jug would be cool. Just gonna keep the stock set up in front. This thing was $150.00 soooo Not too worried about it. I just made a bet w/ Jpres. if he takes it. Check it out on the Eth. chanel

So it would be a good idea to get the belt replaced on the 2008 Agility 50 with 6050Km as soon as possible?
Any good places to order the belt here in the states?
-
try monsterscotterparts .com

Ok took scoot apart this morning and found a air leak in the carb by the elc. choke the o ring was toast.
replaced that. cleaned up the carb and she runs realy good. after a 5 mile test drive and all the rpms are doing great I can tell I stell need a belt. I can now feel it kick in after I throtle up. its like its sliping then it just gos.And when I kick start it It slips also.
-

I would appreciate pics of the belt assembly and where a new drive boss fits in. Others have mentioned removing a washer next to the original drive boss. Where is that located?

lol ya I know thats a old picture that was the belt I got a while back and it was the wrong one.
it only lasted about 3 months.
-
Going to order a new belt in the next few days. is it worth going the extra bucks for a kavler belt or stay with the stock belt.
-
Im using a Malossi kevlar belt just now but will be going back to a rubber one when i renew it. Its easier to see when the rubber belt is wearing and needs replaced, and theyre cheaper.
-
What belt size do I get for the Agility 50? I have seen several sizes listed on different sites.
-
Its easier to see when the rubber belt is wearing and needs replaced,
..when yo snap a kevlar belt, and yes, i have...lol..it turns into little chunks and a big wad of puff...

Welcome to the world of weird belt sizes. It seems all manufacurers vary their sizes so they may not be as you expect. I bought a few that were short even tho they had the size stamped on them.

..been running that belt in my a50 for years...
-
I PROMISE you the 748 is too long. The gates Slinger used is a TINY bit short but the closest to OEM. Either try Slingers # or just buy the OEM part, and forget what the # says. If you can spare the do re me... Buy several different brands, and test fit them. I have a few in a box that didn't fit with all sorts of meaningless #'s on them. It HAS to fit to the top of the clutch, and sit tight on the drive boss. That is the only belt that is correct.
-

..yeah, itsa cpl mm longer than oem...just a cpl..
..been looking around local for a 736...hard to find...
-
That's the deal. Even if you find your optimal #'s it don't mean that's what the belt really is. SUCKS
-
Malossi do a 736 but its kevlar. Im going to replace mine with this in a few weeks when i get paid http://www.chinesemotorcyclepartsonline.co.uk/partno_DB023.php (http://www.chinesemotorcyclepartsonline.co.uk/partno_DB023.php) I may order a 743 and a 729 to mess around a bit and see what works best.
-
The one in the link may do it. The Malossi 736 is the one I used on the Z, and it is QUITE abit longer than the OEM Z. We should set a a belt chart/swap shop here. Make a thread for gently used but incorrect belts, and post how they REALLY fit. I think after answering 2-3 hours of posts I'll put the idea on the General section, and see how it flies. I have maybe 200-250.00 in unusable NEW belts.

thats what I was thinking thats why im thinking of sticking to stock so I can be sure.
I see so many sizes all the time .so I beleave stock size is best.which is the keb7-900 but theam # dont tell me the size.
-
Stock is 729 long by 18 wide by 30 pitch 729-18-30 as far as i know but its finding one that actually measures that size.

man this sucks the stock belt only says keb7-900 no good size numbers to go by.

Looks like Heaters has the OEM in stock http://www.heeters.com/Belts.shtml (http://www.heeters.com/Belts.shtml)

Polini does make a Kevlar and non-kevlar version of all of their belts. This is the one that they recommend w/my Polini variator: http://uk.catalogo.polini.it/catalogo/en/risultato.php?op=po&id=86719 (http://uk.catalogo.polini.it/catalogo/en/risultato.php?op=po&id=86719)
The stock Bando and replacement Gates are both good belts, but they come about 3/8" short of using full variator travel. I will get the Polini sometime in the spring and let everyone know how it does.

wow thanks DAD thats the cheapest I have seen so far.

Let me know what they charge for shipping and if the belt fits.

Hit the jack pot today got a carb and a new belt today.found a place that sales the belts and keeps theam in stock.Nice to know I can find things for my scoot just down the road.belt was 35$ carb was
45$ not bad. the size of the new belt is a 729-17.7-30 it matches up to the old belt realy good you can tell there was some wear on the old belt. Ill be all sit for the summer ride after I put the new carb on.scoot rides realy good with the new belt I beleave I found the size I need now and takeing notes.
-
SWEET! What brands on them?

SWEET! What brands on them?
mmmmmmmmmmmmm o sh** some off the wall chinese brand Ill get the name next time im in there.sorry

Is there any difference between OEM belts KY-23100-KEB7-9000 and KY-23100-KEB7-900? Both seem to have the same specs.

I also came across theam numbers in search of a belt I thing its just a stock #.
and is the same belt. I could be wrong I would stick with the 900.
or find a 729-17.7-30 in a dif brand.
-
I noticed that the OEM belt for the Agility 50 is KY-23100-KEB7-900 and the Agility 125 is KY-23100-KEB7-9000 according to Heaters, so I was wondering if they were the same size belt?
-
took the kymco to work did great on the way there .But on the way home I notice sliping of the darn belt again cant be the belt it must be the clutch. So im asking which spring do I neeed is it the big
spring in the middle and is it easy to do my self.
-
Maybe im wrong but If the clutch was slipping then i doubt changing the springs would make a difference since all they do is keep the clutch from engaging until you hit a set rpm. Surely if they were worn then all it would do is cause the clutch to engage even sooner than before since the springs control when it engages?
As for the torque spring, if that was worn wouldnt it just cause the gearing to go into a lower gear earlier?
You 100% sure you put it all back correctly after you swapped the belt?
-
Yes its geting me to my top end but at atke off its jumping a little. and takeing longer to get to top end.
-
Maybe check the clutch faces themselves arent worn out. My last clutch was a bit slippy when pulling away and when i looked i only had 2 clutch surfaces left instead of the 3 its meant to have. One face had come off completely and was nowhere to be seen, just had the metal,i guess it just disintegrated into dust or something.
Maybe your new belt just needs a few miles to loosen up and settle itself in?
-
could be ill give a few days weather is going to be nice here the next few days after a few days Ill give it another look. the rollers might be geting bad ill open that up tomarrow.
-

That's the point of the belt thread. They are all different regardless of fitment/application. Stay tuned, and we will sort it all out.
-
The #'s are the same so I don't think they would mess w/ you and send something else. LOTS of scoots take the same belt.
-

Blue... You've seen a THOUSAND links to it. Utube/The big spring.
Easier than coming home two days late!
-
Most likely your clutch is shot. Or the bell is glazed. Take it appart, and scuff the pads with 120grit paper, and the bell with 200-400gr
-
took clutch off this morning every looks good a little black dust inside the bell.Pads are realy thick yet.
takeing in to a scoot shope after work to test the spring.I hopeing it just needs alittle cleaning.took sandpapper to it.Im also picking up a bigger main jet for the new carb.that also might help.rpms are geting up there but the scoots not moveing like it should slows down to much with the wind in your face or going up hill.
-
..have you checked your valve clearance lately blue?
..cleaned air filter?
..tire pressure?
..ran a cpl oz of seafoam?
..variator rollers?
..changed oil?
;)
-
3 months ago I did all that but because the way the scoot is moveing im takeing time to do all that again in the next few days im also takeing all the hoses off to look for leaks. the carb and belt are both new and working great. scoot just dont move like it should.
-
Darn it. motorcycle shop said there is to much play in the clutch. looks like ill be ordering a new clutch.
I have herd storys about the clutch going befor the belt.
-
I've never heard of "play" in the clutch... Check the belt fit. It HAS to be on top of the clutch (level with the pulleys, and TIGHT on the drive boss. If there is ANY looseness on the boss the belt is too long. If it is below the top of the clutch it is too narrow or too short.
-
the play in the clutch is that when you squess the clutch together it wiggles up and down a little.the guy at the shope said it should not do that . I dont know the clutch looks very good to me yet Im wondering if theres something ealse wrong im over looking. the belt looks like it fits just fine.
-
Perhaps he is referring to the torque drive. We all seem to have different names/slang for the parts. I attribute that to the literal translations from Tai/Chineese/Jap to English.
-
I dont know what to think the clutch is only like 2 years old if not less. Im geting frustrated over it all
maybe I need a day off of no scoot. I took sandpapper to the pads and cleaned up the bell maybe Ill just put back together and see what it does.
-
anyone know the compression on the agilty if I do a compresion test.
-
Don't know the spec, but over 120 psi will run. Below most likely not. Most stock scoots hit about 140-160
-
thank you very much sir.
-
My pleasure to help you sir. 40 bucks please...
-
check or money order.
-
Cash rules everything around me CREAM get the money!
-
Pay Pal is fine... Luv Ya!
-
Pay Pal is fine... Luv Ya!
luv ya .............your not geting fresh with me now are ya.lol....I might have to charge you 40 for that.
-
Were even in that case...
-
ok took the scoot to work today its only like 2 miles down the rd. I noticed the rps are high but the scoot not moveing like it should with motor running so heigh maybe hefy weights might help I have 6gram now maybe 7 I ounce had 5.5 that worked ok but im thinking the vareator must be worn down some so with 7 's that might bring it back wear it should be.
-
The new belt will restore your "gears". You should do better with the revs where you are used to them. Is your top speed the SAME?
-
I did about 19,000 km on mine Blue and think youre about on the same km? If you are you may need to replace the rear pulley assembly? On mine the disc that moves in and out had come loose last year and once i took of my belt i could move the whole disc without the torque drive bit moving, it had come right off the torque drive. Maybe check that on yours? Mine still ran but when i pulled away it would stick in high gear for a few hundred yards then be ok but my speed was way down, i couldnt get over 30mph. Once i stripped it i saw it but it looked ok when it was still in cos the belt kept it in place.

Begining to think you are right But 2 years ago the back clutch was new thats why I dont under stand it.It should last longer then that. not unless they screwed me over and said they replaced it.plyed around with it today tryed a few dif rollers and its stell doing the same thing gets the rpms up there but the scoot wont move past 30 at times it well get up there but most the time it wont.
-
Did u replace just the clutch tho or the whole pulley assembly? It was my pulley assembly that went, the clutch was fine.
-
ok sorry im lost wear is the pully assembly
-
The 2 discs at the rear that move in and out that your belt goes round on? The ones the torque spring controls. Maybe its not called the pulley assembly but thata what i call it.

lol ya thats what im calling the clutch took a better look at it today and I can feel the bearing moveing kinda rough it should be smooth .dame anyone wan buy a kymco im going chinese.
-
Those pulleys should feel smooth as glass No crunchy stuff. There is a bearing in the engine side that may be shot. You can get just the bearing, and save your halves.
-
takeing it in to see how much a guy well rebuild it for a new is a lot of coin. not less someone is giveing out loans.
-
ok its not the clutch thats wrong I went up to 7gm rollers and it rides a lot better.
stell needs a little fine tuneing.
-
I went up to 7gm rollers and it rides a lot better
...wowww..7gs inna a50....
:o
-
...wowww..7gs inna a50....
I was also running 7gs in my A50 (7.5gs nowadays in my "A72" :-) and it was still revving just below the revlimiter's max. rpm...
It depends on a lot of factors, like OEM vs. aftermarket variator and stiffnes of the spring in the torquedriver.
-
If i go above 6g i lose all decent acceleration and uphill speed dies, no matter what rpm torque spring i try. I need my 5.5g's, they suit me best, run just about perfect with a 1500rpm torque spring ;D
-
Every scoot runs different. I think as stated it depends MOSTLY on the condition/strength of the contra spring.
-
..yeah, with a brand-spanking new malossi 1500 my a50 wont run on more than 5.5s...likes the 5.1s...
..put 7 gs in mine and i might as well just get off and push it up th hills!!...

true that. I seem to find the only way to keep my scoot running nice is with hefy rollers and a wider belt
I thimk it due to the vareator worn down to much maybe shave the boss down or spend the cash for new parts. money I dont have.
