Following on from my previous thread titled New Scooter, New Concern.
I've got a bit further now and related my vibration to be most likely coming from the drive belt area. So today I removed the cover for a little inspection.
The drive belt is in great condition actually, as would be expected from a bike that's only done 1000 mile from new. I ran it up, and noticed it does jump around quite a bit though.
After a closer look around, I noticed the wear line on the variator face. It looks like the belt isn't riding all of the way up the variator. I'd say the wear mark is perhaps 5mm from the outer edge. Is there a common cause for this? Perhaps my variator weights are a little light? Or is that how it's supposed to be? I kind of expected it to use the full area of the variator giving me the tallest possible gearing. It's currently got 12gramme weights from what I can tell.
Have also fitted a tacho a few days back, and at 45mph i'm doing about 7200rpm. Then at 50mph I'm doing 8000rpm or there abouts.
Another thing I noticed was that the variator assembly and weights didn't seem to be very smooth in it's operation. So I took it apart and gave it a good clean and a light greasing. The tube that sits in the middle of the assembly allowing the variator to slide in and out was very dry and stiff in it's movement. Must admit, it runs a lot nicer now I've done that. The belt isn't climbing any higher though I don't think.
Sorry it's a rather large post. Looking forward to your experiences.

Thanks for that KZ. Will look into that. Think I'm going to start another thread now, as I've finally got round to getting the drive cover off to inspect the belt etc.

Thanks for your comment KZ. The belt was looking like my number 1 choice for where the vibration was coming from. It sort of feels like its that sort of area if that makes sense.
Probably due to it being a cheapo belt. Any tips for belts? We cant seem to get Gates belts here in the uk, even though they sell automobile belts here. Perhaps there are chinese brands that are ok?

Theres a Haynes manual for chinese scooters, and it covers most of what you need. Its pretty useful.

You're all right, those tyres are a bit crappy. Fortunately 10" tyres don't seem to be too expensive, but I'd want white walls again.
I have 3.5x10 at the moment, would I have to use the same or can I use better newer style ones? I'm guessing they're radial now.

I love the Piaggio stuff too. Really fancy a Vespa GTS, but they're very pricey here. Also, I'd need to take my bike test to ride anything larger than a 125.

It's a ZNEN ZN125T underneath, basically the same as my bike. If you're from the UK the Lexmoto Tommy or Lexmoto Valencia are the same bike too.
And yes, as already said you need to remove the cowling below the handlebars and it's mounted at the front of the bike. As you will see on the left, I too have pretty much the same bike.

Thanks for the replies. It does feel like harmonics I must admit, and so far am happy to live with it. The dealer I bought it off aren't very helpful and said there's nothing wrong with it. Like you say though, perhaps there isn't anything wrong with it!

It's not yet a problem in the UK, but there has been talks about it just the same on many forums. We can get gas (petrol) with added ethanol, but that so far seems to be the higher octane rating stuff. But only recently have I noticed that we generally run different octane ratings to you guys over the pond. Standard stuff here is 95, then super is 97 or sometimes 99 now. In other parts of Europe ethanol based is becoming more common I believe.
Wish we could buy fuel at $4.39 a gallon, we pay the equivalent of around $9 per UK gallon!
As an example at current exchange rate, it costs $9 to fill my scooter and $124 to fill the tank of my Lexus IS. But that's a whole other subject! I know you guys have suffered ridiculous fuel price increases over the last 10 years too.

The liberty and beverly were everywhere when I was last in Italy. You couldn't walk down a street without seeing one.
Very stable with those nice big wheels. Big wheel scooters haven't caught on in the UK, still not many about. You'd think there would be more with our rubbish roads!

Yeah, mine has fallen off the side stand too. About two days after collecting it from the dealer! I rarely use it, other than for propping it up quickly inbetween doing things. When I do use it I make sure I use the parking brake with it.

Well, I took the scoot out again yesterday on a particularly hilly 50mile round trip. I purposefully gave it some beans on the straight sections and it pulls up to 50mph no problem, but as mentioned as I approach this speed the vibration starts and continues as the scoot pulls through 50mph up to around 55.
However. One stretch was downhill so I was able to get to 50 and back off the throttle. The vibration then stopped. So, it's not the fact that I'm going 50 that's the problem, it must be something else. It's quite a fast vibration, but obviously not wheel related now.
So I can only guess engine or drive? Belt perhaps?
I just didn't expect this on a brand new bike. I've now clocked up 800 mile and it hasn't changed. Oh and another thing, it seems worse after riding for 30 minutes or so, such as when the engine and drivetrain is well and truly warmed through.

Hehe, can't believe how my mind works sometimes!
From what I've seen, most in the UK have a side stand switch. I guess it's to stop people starting the engine and revving it a little and running it over. At least the back wheel is off the floor when the proper stand is used.

So I've just been for a cruise round on my scoot. I got it out of the garage and decided to put it on it's side stand whilst I got my stuff together. Then thought, no I'll put it on the kick stand and start it up to get it warm. Five minutes later of wondering why it wouldn't start... i'd left the side stand down!  |

It's certainly different! Am not sure they sold them in this country. Can't find one for sale anyway! Looks a bit like a Honda Helix or whatever it's called.
It's good to be different anyway. Always a talking point!
