The engine randomly cutoff when scooter stop at stop sign or traffic light. And it get worst and worst. Finally I could not even start out the engine. So I bought new CDI, coil, and Spark plug and try to fix it by myself, but it didn't work. I send it to motorcycle shop and have them fix it for me. They told me it was the battery problem. After they fix it for about a week, Same sh** happen again. So I send it back to them, they finally find the problem was actually form the bad connection between the coil and engine....= ="
They charge me $150 for finding the problem and battery change
and $300 for installing the transmission kit and exhaust. Which I think it was really over charged!!If I have tools, I would install the transmission myself.
Another $150 for finding out the coil connection was lost.
What I have done:
Hoca transmission kit with 10g pulley.
Adjustable CDI+performance spark pluge
Exhaust + bigger jet
MOS cooling light weight fan
Rebuild the seat cover, and make it lower. Because I'm only 5"4.
Some minor after market part.
