Dellorto Jets for Dellorto Carbs at 5mm for 19mm and 21mm Dellorto Style carbs
If you have a carb from Dellorto these are best sizes when doing 70cc kits and exhaust.
The 5mm main jets are for 19mm and 21mm carbs from Dellorto used on two stroke scooters.
Most exhaust upgrades will need 85-90 when using a high performance air filter. If using a 70cc plus air and exaust at least 95 with a 97.5 working real well on Sport Malossi and Polini kits. The better quality your kit and exhaust are the more fuel and air you can add.
