i have about 300 mi. on it now and since new its made a kind of belt slapping noise when taking off from a start. if i take off super slow it does'nt make the noise. just taking off normal without giving alot of juice it makes this noise. is this normal ? does it go away after so long ? seems to run and excellerate fine. any help with this will be appreciated !
-
I've got a noise in my CVT also, it shows up when I come to almost a complete stop and accelerate again. I can't claim that I always accelerate at a slow rate. Performance hasn't seemed to change. I've got 3000 miles on mine.

On my P250S OEM belt was quiet, the new belt slaps around when idling.
It has the same dimensions as OEM.
Strange.

thanks for the info! it goes so good i figure it can't be hurting anything. i'll run it up to the 600 mile check up and let them see if there's a problem.
-
A few of us have what we call a growl. On a quick take off, it growls up to about 15 or 20 mph, then it gets quiet. It does not seem to affect power. :)

I have a Yager 200 with 1200 miles...pretty gentle breakin by myself. I'm just now experiencing the 'shudder' accelerating from a stop between 5 and 10 mph. Sometimes just a little. Sometimes alot. Seems like a belt/variator problem...not engine related. I'll be taking it back to the dealer to have it looked at under warranty.
Otherwise, the Yager is a great ride...no other complaints.

No problem retread. It'll probably be a week or so until I take in due to my ride situation.

thanks wil b. it'll be 2 or 3 weeks before i hit 600mi. would be nice to know before than if there's a problem.

I was having the shudder and growl problem when accelerating between 0-7 MPH. Just picked up the scooter yesterday morning. The dealer replaced the gearing weights (is that the right name for it?) and said a few of them weren't perfectly symmetrical (or round). That could have been from wear and tear, or the way they were made.
Anyway, 95 percent of the problem has been eliminated. I experienced some shuddering, but no where near what it was before, and it was only a few times, and not every time I accelerated from stop.. Just rode in from South New Jersey to University City in Philadelphia. No problems. It's great to have my scooter back, though the engine feels different -- like the timing I've grown accustomed to is off, but I'm willing to become reacquainted again with my bike.

Wolf, I'm ready to take mine in for the same thing. I presume you took it to Mark. Was it warrenty work? How long did it take? I hope I can get him to order parts while I hold onto the bike. My big problem is that my wife does not drive, so I won't have a ride home.

Hi Rich,
Yes the warranty covered it all, but it was there for about two weeks. However, it only took him a few days to work out the engine, it was the new seat latch that took so long to arrive. The seat would not stay closed, causing the under the seat light to go on and causing a drain on the battery. I had to drive down, disconnect the battery and keep all the screws in an envelope when I dropped it off.
I know what you mean about not having a ride. When I took it down I walked to the Lindenwold station and took a train back to Collingswood. It seems this problem is becoming common for the Yager. Hey -- if there's a recall -- new scooters for us!

Yeh Wolf, I'll keep waiting for the new scoot. In the meantime you may have seen that I installed the flashing brakes. They work well, you may want to consider doing it, particularly since you spend time on The Ben. I made my first Walt crossing about a week ago. Coming home I hit 65, (If the speedo is accurate) which is the fastest I've gone, but still not WOT. But I guess you're an old hand at that.
See Ya,

Hi...just reporting in on the 'shudder.' I took my Yager (almost 1400 miles so far) on a couple of extended higher speed runs 55-65+mph and the shudder seemed to disappear for awhile afterward. The shudder came back though. Seems to me to be a belt problem, although another poster here had the dealer work on the roller weights. In any case I am very easy on these machines, and the belt and rollers should last at least 10,000 miles before replacing. We'll see what the dealer says. As delivered, the transmission had a perfect beautiful smooth takeup from idle.
I'm going to take back to the dealer soon, so I can get my complaint registed within the first year of the warranty!
Otherwise....WHAT A FABULOUS MACHINE! In all other respects, this scoot is a wonderful bang-for-the-buck modern scoot. My next goal is to take a 200 mile weekend road trip on country roads to the Starved Rock area in Illinois. Before the snow comes.........

Hello Everyone,
I have a 2009 Xciting 500. Got it a few months ago for a great price because it was a demo with about 3000 miles on it. Anyway after taking a 4 hour motorcycle course in very hot weather I heard what I thought was a noise from a breaking belt. For a few weeks thereafter I had a growling noise on slow starts uo to about 15mph. I took it back to the dealer and they checked belts, rollers, etc. and found nothing really wrong. They lubbed everything, seemed much better but occasionally the growl comes back. I read a comment on this forum which I do now each time I hear the noice. While stopped I rev the engine to a pretty high RPM while holding both breaks. I do this for only a few seconds and the noice goes away. I am mechanically "declined" so I'm not sure exactly what it does but whatever, it seems to work very well. Growling noise goes away for a few days. Performance has never suffered but the noise can certainly be annoying. I love my Kymco and this forum. Good scooting to all!

mine has'd growled since day 1. now with cooler weather and riding with helmet i hear it growl with any accelleration. if i take off really slow there is no growl. just the opposite of what everyone here says. i did the brake and excell thing and quiets for about the 1'st take off. all take off's are strong and it runs great. i'm thinking some of the yagers just make the growl or it's inconsistent chinese manufacture belts or other drive part.

I don't have a growl or shudder, I've got a slight, very high-pitched whistle that's coming from the clutch as it engages on hard takeoffs, and a slight rattle (that I can only hear if I'm riding next to a wall), but only at about 3800 to 4000 RPM engine speed.
I've checked all the bolts, they're tight, I think it's the clutch chattering.
So, it whistles from a dead stop, then chatters if the engine isn't turning fast enough to positively engage the clutch.
My thinking is that the clutch on this bike seems to be undersized, and to compensate, they made the engagement speed higher to give the feel of a stronger takeoff from standstill. But that's causing problems at lower engine speeds.
Anyone know of a better aftermarket clutch that'll fit the Yager?

Hi guys. Every scooter will shudder at a different rpm. It is more of a "harmonic/reaction" type deal. you have 40ish independent moving parts all w/ their own job to do as springs wear, rollers flatten, ramps gloss ect. it will change the relation to the next part. These are really not precision machines but rather simple mechanical assemblies. You can make any scooter make the growl you all refer to by finding the rpms that one part falters at. the effect will travel through the drive train, and you get the rest. If you were to run the machine at the growl rpms only the life span would quickly diminish. The only real solution is to have the "Trans." serviced/inspected annually, and replace the worn bits. Better parts mean less wear but even w/ all the top bits installed you will still find you can make the machine growl. It is just the nature of the beast. New Machine ...Priceless/ Finding out more about it...Not always what you thought.

I had a similar sound. it turned out to be chattering valves that needed to be tightened. The dealer repaired it.

very good explination of what i was thinking. thanks

Hey, gang! Here is my opinion so treat it for what it is worth: My Agility 50 had some noises on acceleration which never seemed to get worse. The Yager had the same noises and very shortly developed the shudder. Here is the opinion: some guy on the chinese scoot forum took some movies of a variator belt while the bike was on the center stand and he revved it up slowly. That variator belt had some of the wildest sinusoidal transitions I have ever seen! I figured the "waves" in the slack side were the cause of most of the noise on acceleration. The shudder I tagged as being in the clutch. That was the worst when "slipping" along at slow speed or taking off slowly. It disappears once the bike gets going. My Yager has over 8000 miles on it and the noises/vibrations have not seemed to change.

My People S 250 shutters some on deceleration, but not on acceleration.

Finally got the Yager back from the dealer just in time for the Chicago riding season! Well, in time for me to winterize and pull the battery at least.
I took in a month ago to have the dealer check out the 'shudder' between 5 and 8 mph that had developed after breakin. The scoot now has 2,000 miles on her.
The mechanic cleaned out the variator facings and belt housings...he said was full or crud from the belt. He also said that this happens more often on the bigger engined scoots than on the 50cc ones. I've dealt with this mechanic before and pretty much trust his judgement. He said that it may or may not reoccur. Anyhow no charge to me for the service and if this happens again, I'll open up the trans housing myself (looks easy) and see if I can clean out.
Happy Holiday Season to All!
