Crapping on the road, the original spring clutch Kymco Dink 150 cc needs 20 km/h to get the full clutch engaged (at 4000 RPM). Less than 20 km/h the clutch will overheated due to the friction zone. I modified the clutch spring to Kitaco 1000 RPM, the clutch is full engaged at 3000 RPM, so reduced the minimum speed to around 12 km/h. It is good for passing through the traffic jam.
