People 150 seems slow.

[DeKing]

My new to me 150 with just over 900 miles can't seem to get past 42 mph on a long flat run. I'm no feather weight, about 195 lbs., but I hoped I could get at least 55 out of it. The carb was cleaned by the dealer and it runs nice otherwise. Any advise?

That's very slow p150 should top out at 60-65 on the Speedo. Check tire pressure. Also did the previous owner do the first 600km service and adjust the valves correctly? P150 air filters dirty quickly also. Good luck!!!

I checked the air cleaner and it's very clean. the tire pressure is 33lb front and back. The more I ride it the more I think it may be actually a 50cc by the performance. I have a neighbor lady with a 50cc Chinese scooter that can put me to shame. The registration says 150 and the little symbol on the sides of the scooter say 150. This scooter originally belonged to couple in Key West and this was the wife's scooter. I am wondering if the husband had it detuned or swapped the 150 engine for a 50 so his wife could not go very fast. Is there a way I can tell what I have without tearing the scooter apart

Very easy, is there a oil dipstick on the RH side of the motor? I would HIGHLY doubt that someone would ever swap the 50cc into the 150 totally pointless and not that easy to do. Is your seat a long seat or a small one person saddle? Do you have a little battery door on the right side body panel? Something is very wrong with your scooter my friend. Take if to a shop if you don't really know how to work on scoots because it may be something difficult to fix.

Agree with B&L.  You should be hitting in the mid-fifties (actual) and low-sixties (speedometer).

Thanks for all of your responses. As I originally said, I'm very new to the Kymco. Of course the previous owners didn't bother to keep any records to pass on. I will definitely call the dealer tomorrow and see if he will help.

The dealer took my scooter back to his shop and eventually replaced the carburetor. Now it runs like a scalded dog. As soon as I pulled out of my driveway I felt the difference and it easily got up to an indicated 65 MPH. I know the speedo is pretty optimistic but I'm guessing the real speed is somewhere north of 55, and that's just fine.

Now that's what I'm talkin' about!

[BettinANDlosing]

Good fix! Glad to hear a dealer that knows how to fix something. Working at one I hear loads of people say "I took it to a shop and now it's worse". Lol

Glad to hear you are back up and running. The P150 is such a great bike, you don't want to miss any riding time. Enjoy!
