Hello all,
I'm having a little difficulty tuning a Kymco ZX 50 Super Fever. This is what the current set-up is:
Airsal T6 48mm
Arreche 19mm carb
Motorio pipe
Motorio clutch
Motorio "Yellow" torque driver spring
Motorio variator
5.0g roller weights
(The Motorio stuff comes "pre-packaged" for the ZX 50, so I'm confident they are the right components for this level of tune)
Heres the problem:
The scooter just sits still instead of taking off from a stop. I have to hold the throttle WOT and it gradually takes off after a few seconds. I'm convinced the issue is the carb set-up, but was looking for input from this community before taking stupid risks.
The reason I suspect the carb is because if I remove the OEM airbox, it takes off just fine. Put the airbox (de-snorked) back on and it bogs. My question is, is the main jet too big?
The thing is, with the current main jet, my plug is just a very dark gray color (with the box on) when I was able to do a WOT plug chop. Therefore I am a little nervous about installing the next smaller jet in it and running it down the road.
Thanks for any assistance!
