Please help, what is wrong ?...

Hi to all,

Motor: 50cc
Carb: 18mm
Main jet: #82
Camshaft: Naraku V2
Pilot jet: #stock
Valve: Intake: .005"\ Exhaust: .005"
Rollers:5g. Dr Pulley sliders
Speed: 35 Mph, downhill 45Mph.
CDI: Unrestricted Naraku

In CVT/vario:
Yellow malossi clutch springs and Dr Pulley slider rolls.
This is only settings setup, this scooter is capable of running, at least...

I have done, tested main yet 85 & 88, scooter is choking.

All the possible settings in the CVT, if I am adding normal rolls and not Dr Pulley sliders, they become after 40km Dr pulley sliders so I have changed 6sets of rolls.

Strange is, if to add normal rolls with weight 5g instead of Dr Pulley sliders, performance Is even worse, barely moving.

Nothing improve performance, spent much money, but still...
In my country I cannot set Big Bore kit, otherwise it would be already in use.

Ordered Polini CVT rolls set, not tested yet, hoping best.

What I want, more power/acceleration/top speed, this is what I have done:
naraku camshaft
Leo Vince excsaust
Dr Pulley sliders
Naraku unrestricted CDI.
Better Naraku vent in the engine ( opposite side of the CVT ), as its heating up very fast.
Iridium spark plug.

What is wrong, with this Magic Kymco People S, 50cc, 4stroke model?

How much do you weigh? For a 50cc motor your 35 on the flat 45 downhill is about right I would guess using mine as a comparison. I weigh 210lbs and mine doesnt go much past 30 unless the wind is behind me or I'm going downhill.

there is no replacement for displacement. if you want more power, install a 47mm or 50mm bore.
