Perfect replacement / tuning for a GY6 Benzhou 50cc Scooter. Mind you folks have to realize there is no unique recipe with those Scooter parts, a lot of variables depending on your configuration, weight etc. Keep on swapping springs and variateur Rollers until you find the sweet spot for you.

These give better throttle response and uphill speed on 80cc and 100cc.On 50cc the contra spring cuts take off speed keeping 50cc rpm very high not reaching over gear "Belt to open clutch fully".The "clutch springs" give better pulling power from stopping to pulling away on 50cc,80cc and 100cc.When reinstalling the clutch the easiest way to put the belt back on is to squeeze the clutch open using both hands holding open put the belt on the open clutch then reinstall the clutch with the belt already holding the clutch open to fit over variator easily.Install a new belt also check your variator and weights for wear and no binding.I use Wingsmoto Roller Performance 4 Gram Weights 16X13 in all my mopeds and servicing others mopeds.Caution don't go full throttle constantly down hill's.

Perfect medium spring for your scooter
