Question about 1987 kawasaki GPZ 500 S - GPX 500 R
My Daelim scooter has lost acceleration from a standing start and strugles at low speed up hills. Once moving above 30 kph it still performs very well and there is no loss of maximum speed. The only way I can describe the difference in performance is thta it is like setting off or traveling at low speeds in 3rd gear. I have removed the belt drive cover and observed that the front drive pulley closes half way before the clutch on the rear pulley starts to engage.
I have no experience of variable belt drives and I would welcome any advice as to when the clutch should engage along with any other comments you could make.
Replace your big clutch spring!!!!!!!! a 1000rpm spring. If the spring isn't stiff enough your scooter lose alot of its torque! and the spring loses its stiffness after some time.. that is normal The spring has the same effect as changing back a gear on a motorcycle. try it! I guarentee it.

If it has a 4 stroke engine then check the compression. You may have bad valves. If it's a two stroke engine the exhaust port(s) may be plugged a bit with carbon buildup. Clean air filter? Exhaust pipe allowing clear exit of exhaust presure?

If you say the scooter struggles at low speed up hills you need to determine if the cluth is spinning
Put the scooter in front of a brick wall or something that will not move
open accelerator and see if engine races ad scooter does not gerk or try to climb wall
If this is the case you have a clutch prolem
you will need to replace clutch
