- Data Sheet
DetailsThe 5mm jets will fit any Dellorto carb from 19 to 21mm in diameter.To set the carb up one usually starts with an overlarge mainjet. This will cause the engine to missfire (fourstroke) on full throttle. You then gradually decrease the mainjet in size (in steps of 5) until the engine starts running properly. Finetuning is then achieved by juggling around with the in-between sizes. Be careful: too small a mainjet will result in weak mixture and piston seizures.
