Agility 50 / 2008 Agility 50 rattling at speed
« on: June 30, 2012, 07:33:56 PM »
Hello, fellow Agility owners!

I've had my little Agility for almost exactly a year now.  It's been a maintenance headache up to this point.. but how much I save on fuel and insurance is reason enough to keep on going.
Plus, I think we can all agree, Kymcos are fun scooters.

So here's the story... The scooter is a 2008 model with 8100 km on the clock.
I've recently had the carbuerator jetted and cleaned, and the engine was replaced over the winter.

Currently, the scooter runs fine... but something is worrying me.  Getting up to speed (30-40mph) is no issue, and doesn't rise any concerns.
But when I'm at speed, traveling between 30 and 40mph, something disconcerting happens.  A rattling sound can be heard coming from under the scooter... (and this is just for the sake of clarity) it sounds like something small is bouncing around inside the engine... kind of like when you drop a piece of plastic into a fan.

Note: This only happens when the throttle is fully opened (grip completely pulled back) and the bike is traveling at speed, as described above.

This worries me, because I'm afraid if it goes ignored it could lead to another new engine!
What are the probable causes and solutions?

Thanks in advance, fellow riders
