Slow 2007 scooter. Don't know what's wrong

[teahead]

Okay, my wife's friend picked up a 2007 People 50 2T.  My wife has a 2006, same thing.

Not sure what's wrong, but her friend's 2007 is way slower than my wife's 2006.  The 2007 has a few more miles (like 1,000) total and the 2006 has like 250.

But the 2006 is way faster, pulls way more stronger, and goes up hills faster.

The 2006 is supposedly ALL STOCK, while the 2007 was supposedly derestricted.  Haven't torn it up apart to see if it has the derestrictor bushing in there.


I cleaned the 2007's carb.  No change.  I installed a new hi performance coil since the old one was bad.  I didn't do anything w/the CDI, but I"m just amazed how low on power the 2007 is compared to the 2006.

Any one have any ideas?

Welcome to the forum 

Right around 2006/2007 Kymco started putting a more restricted exhaust on all their scooters. So, that's definitely a possibility. Also, I know after I put my derestricted boss in the rpms really dropped and so did low end acceleration. Of course I could get up to 40 mph after the change. Before I couldn't get past 30. Umm... Trying to think... Check compression, change the plug(if you haven't already), and check the drive belt. Other than that, I can't think of anything else. Good luck, maybe somebody else will chime in with some suggestions...

Thanks for the reply.

Any recommendations on exhaust?  For a fairly stock scooter?  ANd one that could still be good in case one would want to later put maybe a 70cc head kit on it?



I know hardly anything on scooters.  Would the rollers possibly have "flat spots"?  What's an ideal compression reading?
