Aerox Main jet question

[Aerox_enthusiast]

I recently bought a new cylinder: Top Performance 70cc (Pink) with carburetor Dellorto 21mm PHBG (racing edition) this is black with the nut underneath for easy replacement of the nozzle. I also bought a new set of jets for this. My question to you is which main jet number should I start with (I prefer a rich mixture and to lower it to a brown spark plug) because I am not very familiar.

Scooter components:
Yamaha Aerox R 2005 horizontal minarel
Top performance 70cc Pink
Dellorto 21mm PHBG (racing edition)
Vforce 3 reed valve
Yasuni R exhaust

Depends, I’m guessing you’re running a stock filter? If so, start off with a 96 and go down from there.

I had a very similar setup with same carb en cylinder, i was running an 88 dellorto. I did modify the air filter to get more air through it though.
