- Data Sheet
DetailsThe 6mm jets will fit any Dellorto carb with a diameter of 12 to 17.5 mm. 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) untill 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 a lean mixture and piston seizures.
