Hello, way back in January I wrote about the same problem. Except mine would wobble all the time. My responses to my post really didn't help out my situation. So I was pretty much resigned to living with the wobble. So after I passed the problem by my local mechanics they suggested the head bearing. But I did the head bearing test as well as the left/right test, and did the poor man's balancing. All seemed to work as advertised. But being motocross guys, they asked about the fork oil. Now I wouldn't suggest you go tearing into a new scooter. But mine is old and I am the third owner, so I said "What the Heck! I have a spare scoot anyways." Fork oil can get old and rancid, and will foam after a long period of time. If you research your Kymco book , you will notice nowhere does it mention anything about fork oil. Thats because they make it extremely hard to change. Basically its a plastic cap, held on by a wire ring, holding a big spring in place (and the oil back). So you have to remove your fender, front wheel, and pull off both forks. I destroyed both retainers in the removal process. But a couple of 1 1/4" snap rings from Ace solved that problem. Don't quote me on the size, I'm going off my failing memory. I poured the fork oil into a measuring cup and got approximately 150 ml from each. The old oil was as black as can be. New fork oil is clear like mineral oil. I used 7 wt which is an average weight. Bought it from the local Honda dealership. Put back in the same ml, with just a hair over to compensate for breakdown. With my wife's help we put the plug and snap ring back in. And installation was the reverse of removal. I swear the ride feels tighter and less wobbly. It may be that the factory short changed one of your forks, or one fork leaks. Or it may be as Ole Bull says, that its the People's pogo stick design. But anyways, thats my 2 cents.
