Tuning Matters.com How To Quickly Determine The (Dell'Orto) Carburetor Main Jet Size. It will put you in the ballpark. Heck read into that site, super detailed! Get a box of fresh/correct spark plugs and do some plug chops. I use a CHT gauge on my builds. Cheap-o Trail-Tech brand. I forgot what I used with my last 70cc set-up on my Zuma bug-eye. I had a Malossi cast iron street 70cc and a Yasuni R, but I ran a 19mm carb with the stock airbox-just removed the snorkel. Ran great and was super reliable. I think my friend knows what base jetting's (dont forget the idle/pilot jet!) is and I will reach out to him. I have a 17.5 carb for my pre-bug Zuma but I'm going with a Malossi cast iron 50cc with a Yasuni Z exhaust. I have a Piaggio Liberty 150 for faster speeds.
