Dellorto 5mm Jet packs (5 packs)

Dellorto Main Jet's 5 packs

We are selling these jets in packs of 5 and in the range of the numbers shown odd or even.. If you order a 50's jet pack you will either get all the odd or all the even numbers in that jet range. 1 jet hardly makes a difference so we split em up into 2's to widen your variety of jets. For instance in a 50's range you will recieve #50,52,54,56,58 and/or 51,53,55,57,59,.

This is the main jet for Dellorto SHA and PHBG carburetors. Rejetting is required every time you change any aspect of your engine configuration.





CHINA 2 Strokers>>> I run a head, a pipe , a intake and a Dellorto 15.15 carb. For this application I had to downjet from the stock #67 jet to a #57 jet.. The #57 dellorto jet is about the same size as whet the 14mm NT China carbs use for a jet . The CNS "race Carb" is a 15mm and runs a 60's range jet and it's too fat out of the box.

15.15's need to be in the lower 50's range for optimal performance. Remember climate, elevation, and upgrades all have a factor in what jet is right for you. There's no one jet thats perfect for everybody in most cases.. Not if you want to dial it in as best you can.
