@Vincent - Now that you're had this scooter for a month, how is it performing? I'm looking at a 2009 Yager with only 3000 miles listed on Craigslist for my daughter. I haven't gone to see it yet, but it looks like a nice scooter. The seller is asking $1600, but I'm thinking it's probably one with $1100. When I see bikes or scooters several years old with low mileage, it sounds like a bike that sat in the garage most of the time and probably had zero maintenance.

Thanks,
Carrie

Fuel tank parts diagram indicates a vacuum-operated pulse-pump.  Minimum intake vacuum at wide-open-throttle may be resulting in fewer pulses to pump . . reducing outlet fuel flow and not maintaining an adequate carb fuel bowl level (temporary lean).

Thank you for responding. I don't have a login to the link you referenced, but I can see the pump on this page, http://bit.ly/2dtAXVg. If there is a minimum intake vacuum with the throttle wide open, then wouldn't every People S250 have this problem?
Every article I find discusses issues with scooters running or not starting like this one, http://bit.ly/2cXkvy5. I cannot find a single post where anyone discusses issues with running any scooter at top speeds, much less a Kymco People.

I posted this in the Kymco S250 forum. I thought I would post it here also, since this seems to be more of a technical/repair section of the forums.

I was looking at scooters for my daughter in college and test drove a 2009 Kymco People 250S at our local dealer. It only had 3000 miles on it.  I've always ridden motorcycles and fell in love with the People, so much that I brought it home for myself! The first month I was mainly riding it on county highways with a top speed of 60-70 mph on the speedo and had no problems.

I finally took the scoot on a 600 mile round trip when I first experienced the issue. I'm hoping someone here may have some ideas.

I had been on an interstate for about 60 miles when I first experienced the problem. I had been riding about 80-85 MPH on the speedo and found myself between 2 semi's. I opened the throttle all the way and lost power (wouldn't you know it would occur between 2 semi's!) All the electricals were on, but it felt like the gas had been cut off. I let off the throttle and power came back at around 60 MPH. Since then I have found this is an intermittant issue.  With the throttle wide open or close to wide open (80-90 mph on the speedo), the scooter will lose power. All the electricals are still on, but it feels like the fuel has been cut off.   It I let off the throttle and drop the speed down to around 60 mph, power returns. If I pull off the interstate and completely shut the scooter off for a few minutes, the issue may not return at all; or the scooter will fine for a few miles with the throttle wide open then the problem start back up again. I can never tell for sure when it will happen. I have driven 100 miles and not experienced the problem, or had this problem within the first 5 miles of a trip. There is nothing I have found that will make the scooter do this. It can occur with the gas tank full, half full, or close to empty. I talked to the mechanic at our local Kymco dealer, and he has never seen this problem. I am concerned that if I take my scooter to the dealership, the issue may not occur when they test ride it.

Has anyone else experienced this problem?

Thanks,
Carrie
