Just bought People 250 S

[Hoolander2]

Now that I look at that tool some more, it may not be long enough or beefy enough to do your 250.  You could, perhaps, slide a piece of pipe over the handle to make it longer.

Do you by any chance know what is the width between holes in the face plate?
It is 8 cm on my scoot.
Alternatively, what is the max width to which the tool can be stretched?
Tnx.

[Hoolander2]

I don't know the answer to either question right now.  It's night here so I don't want to go out and look now.  I do know that my tool will open up more than I need it to.  I think the price was about $26 USDollars plus shipping.

Ok, the measurement between holes on my variator is 10.5 cm.   My tool opens up to at least 14 cm.

Thank you very much.
That is 2.5 cm more than on my scoot.

I am aiming for this tool.
Its length is 25 cm.
I hope it will fit my purpose...

Just so you know, I've read through your whole PS250 diary here and will continue to follow it.  I just bought a (non-S) P250 myself, and am soaking up all the information I can.  Thanks, and keep it up.

The tool works. Yesterday I have changed the belt on my gf's A125 - http://www.kymcoforum.com/index.php?topic=1493.msg46031#msg46031 - and today I have changed the roller weights and the belt on my P250S.

You can change the belt on A125 without removing the clutch but it seems it is not possible with P250S, because you cannot compress the clutch with your hands in order to pull out the belt, there is no space between clutch and the outer vario casing. So I had to remove the clutch too, inspect it, clean the dust and put everything back. Service manual shows the same. The rollers and belt were in quite good condition after 15.000 kms (OEM belt was Mitsubishi made, the new one is Dayco, as you can see, they are the same). Unfortunately, I have purchased some Chinese crap roller weights, they have some kind of plastic surface that can roll around the metal core?!? This crap cannot last, I bet they will shred to pieces in no time. I have another set of 19g rollers (OEMs are 21), so if they go bad during the summer, I will use lighter ones until I buy some decent rollers or even Kymco's as their quality seems to be supreme.

Oh, yes, there is NO WAY to loosen the nut on the face plate where rollers are, or the one keeping the clutch in place. I tried standard 40 cm wrench, then I tried something that looks like a crowbar and it is used to remove wheel nuts and could not. Finally, I had one person keeping the rear brake lever pressed, the other person using the pulley blocking tool and I have extended regular wrench with 1.5 m pipe (!) shown in the pictures, and only then I have managed to loosen it. Even WD40 did not help before that. The mechanic must have used the impact wrench in the past and with 1.5 m lever you can normally loosen nuts on Caterpillar machines or railway wagons!

I have cleaned everything, put everything back together and went for 300 m test ride. Everything goes smoothly, but the belt makes "flapping" sound, especially when the scoot is idling that was not present before. I did not make a mistake assembling everything back and the belt has the same length and width, so I do not understand what might be the problem. This fact and crappy replacement Chinese rollers make me less happy about the work I did. Anyway, I think that People's OEM belt may last well into 16-17.000 kms under normal conditions as my OEM looked great when replaced today after 15.000 kms.

Good work, Axy.    Perhaps the new belt just needs time to break in.  May I suggest you keep a check on the heat generated by your CVT over the next few days?  Just a touch with the fingers will tell something.  I have a theory (maybe stupid) that the clutch dust inside the CVT acts as sort of a minor lubricant for the belt. 

I'm thinking yours will smooth out with a little time.

Tnx for the good wishes, but there is no such thing as break in with this belt. It will not fit better, "snug in" better or anything else as the time goes. These belts do not stretch and service wear is only about 1-1.5 mm max over 15.000 kms. So, I still do not understand where is this flapping noise coming from. When you look at the belt with cover removed, you can see there is quite some free play. The problem is that I did not look at the old belt when the engine is started and cover removed, so I do not have a reference point for comparison. Strange.

I am preparing for the first test drive today with both scoots.

p.s. Completed 10 km test drive of both scoots, everything is as smooth as it should be. Vario cover casing temperature seems to be normal (one can keep hand on it), at least normal for external temperature of 35 + C we have here nowadays. I will not yet declare this a win, especially not with el cheapo Chinese plastic crap rollers I have installed.

Take some consolation in this:  When I installed a new Gates belt on the Xciting 500 it did exactly the same thing you describe!  Flapping like crazy as I observed it with vario cover off.  Then I realized that running engine with that cover off meant the clutch outer bearing wasn't in place!  Yikes!  Anyway, with everything put back together it still made flapping noise for several miles and then smoothed out.  Still I noticed excessive heat of the whole CVT -- plus the ride just wasn't smooth.  So I took the Gates belt off.  Months later I noticed the Gates belt had big tear in it!  I still don't know the reasons for all that.  Think I read somewhere the Gates belt is slightly longer than the stock one.

They did change belt size from year to year.

Jenny, is that true for the 250S or the 500?   Or both? 

[shalbern]

Jenny,

Do you stock a replacement belt for my 2007 p250? (995x24x30?) If so how much?

Thanks

17.500 km.

New issue: I have noticed that suddenly the consumption jumped up 20 %. Usually, it is around 4.2 l/100 km and during the past two tanks it consumed 5.0 l/100 km (driving style, weather conditions, route and driver were the same).

After analysis I have realized that there is nothing wrong with consumption, but tachometer has started showing 20 % less covered distance! Out of the blue.

So, during the last tank, tacho showed that I have covered 118 kms while in reality it was 141 kms. It used 6 l of fuel (5.1 l/100 km according to "wrong" mileage and expected 4.2 l/100 km in reality, if corrected mileage was used).

It is a paradox that speedometer is now showing almost correct speed. In the past it was 15 % off as with all Kymcos, but now it is spot on.

I have to wait now and see which 100 US$ part that cannot be purchased anywhere else but in Kymco after 3 months of waiting will go wrong. (speedo cable already broke once at around 7000 kms).
