Hello,
I have 75cc kit installed on a scooter.
Recently i changed carburator and air filter with sym orbit2 deni carb and airbox with paper filter.
I removed restriction screen from filter and jetted carb with 89main jet (same one i was running with stock carb).
Now the problem is that scooter sputters at take off.
If i try less air it sputters even more, if i try more air it sputters the same.
Auto enricher is 100% working.
There is a little sign of petrol in airbox, should i try smaller jet?
Now about roller weights.
I had 6g weights it and scooter was doing over 80kph, i wanted a little bit more so i installed 8g roller weights, now top speed is reduced to 68kph. This is against logic isnt it? What can be the problem?
Thank you for your time and anwsers
