What you need to tube your dellorto clone 15/15

I want to see jet size! I street with the 70. Now I can go down if needed.
If you need to upjet, you'll need the next up kit.

I mean it's a 5pk of main jets you can't really screw that up! The price is right! N yes I'll probably need to buy more at some point

Jetting for "The Bike"

Purchase was smooth and easy, fast shipping, A+ transaction.
Got bike for $100 from someone who couldn't get sprockets lined up properly& did my 1st build. Drilled out the muffler so needed to jet the carb accordingly. Original jet size is unmarked but was too rich & 4 stroking. The 68 jet gives the best all speed performance with minimal 4 stroking at WOT at my elevation of 386'.
Check out the before & finished pics, tried to use as much of the stuff on it but upgraded to hub drive with 48 tooth rear sprocket for better pull on hills. Dual pull brake lever & upgraded motor mounts to get proper placement in the Schwinn frame.

Run right

With a carb that has no tuning screws these jets are a necessary item
