Hello

Thanks to all of you.

The country I do live is Switzerland





I will try to check the carburetor and the spark etc. as soon as possible again: but at the moment I am very pleased with the top speed of my kymco.

Next is to change the front tire. But this is no big problem: I have close to me a farmer, which has the equipment to change all kinds of tires. He takes only 30 dollar to change the tire  And then I have to adjust the front light, it beams to high. But there is a screw, should be no problem.

Thanks a lot to all of you, thanks a lot for the cool videos!

All the best

Here we are....

Hello all

I cleaned the carburetor and the old nozzles with break-cleaner (as I write above). The result was, the kymco runed faster, but not perfect.

I bought yesterday two new nozzles. The big one and the small one in the middle of the carburetor.

Now, the Kymco runs up to 85 miles  !

Incredible...

So the problem was, that there was a film or covering on the nozzle even if the nozzle looked clean.

Great!!

I am very happy.

Thanks and all the best

Hello 

Thanks a lot to all and specially to REDK

I do live on about 800 Meters. So there is no problem with high altitude. But when I go up to the mountains, the foresight 250 runs about 60 km/h on 3000 Meters... big difference.

No: the 800 meters are "nothing" to consider.

I will try to run some highway Kilometers and then I try to adjust the carburetor as REDK told me: I hope, I will achieve this.

Thanks

Hello

Thank you very much.

1. Did the bike sit for a period of time? It was used very few the last 2 or 3 years. But it was used for small trips on sunday.

2. Have the rollers been changed? No, there is nothing changed (not the rollers where the belt is transmissioned).

3. Was the previous owner a tinkerer type person? No, but very old. The maintenance was made by a kymco dealer at 300km, 3000km, 7000km and 9'000 km (2 years ago). The kymco was used rarely the last two years (the owner got retired).

4. Does it feel like it runs out of power, misses, backfires, etc? Not at all: the scooter goes very good and smooth but strong. The acceleration is great up to 80, 90 and then it's over. I was today on the high way...with wind in the back I did about 105, maybe 110. Against the wind 100.

But changing the fuel filter is a good idea. And of course: I will also change the break liquid: I changed it two times on my honda, so I know how to do. Maybe this change will make the scooter faster   

Cleaning the carburator? This is something I have to let do the dealer.  But here in Switzerland, the Dealer takes 100 Dollars / hour and I do earn 22 dollars/hour... And If the dealer spends two or three hours, this makes me "poor" 

I bought today the new air filter (about 39 dollars...): I will replace the cleaned, old filter tomorow. Maybe there will be an effect.

But it is not very nice to feel no acceleration. I can not overtake a truck safely. With the old 250 foresight (which has 35'000) I can easy overtake a truck that drives 110 or 120.

Thank you very much. I will report you, if I find out something.

Yours

Hello

I am almost 50, do live in Switzerland and I just purchased a kymco people s250 in blue with about 6'000 miles. I am very happy with this scooter.

I changed the spark, the engine oil, the transmission oil. But I am a office clerk "without" mechanical know-how.

The air filter was totaly dirty with black dust: but I had not a new air filter, so I cleaned the air filter with pressured-air. It is now "cleaned" and quite OK.

My problem: the kymco runs still only up to 90 km/h quit normal, but then it takes a long time to get up to 110 km/h. And 110 km/h is the high speed... but it should be 130 km/h on the speedometer. (I have an older foresight 250: an the foresight runs much more faster after 100 km/h).

After my cleaning und maintenance and changing oil, the kymco was only a little bit faster, but still too slow after 90 km/h.

(sorry for my english, I try my best....)

The old spark (which I replaced) was black on the top. So I think, that there is too much fuel?

So I have two questions: 

What can be the reason for the insufficient top speed?

Can it be the carburetor? How do I adjust more air oder less fuel? I know the idle screw, but where ist the screw to adjust the air-fuel mixture? In which direction I do have to turn the screw?? Does any one have a picture of this screw?

Is there another possible reason for the low top speed?

Maybe I have to adjust the valves? 

Or can it be the choke (not dismissing 100%?) ?

I am glad about every tipp and hint! And I hope, that I will found some help in this huge forum. Thanks a lot! 

Wish you a warm spring time an hot summer

Yours, from Switzerland
