Carb Jets for Lifan 140cc in ATC 70

[Henry89]

I'm rebuilding a Honda ATC70 and installing a Lifan 140cc motor with a 22mm Mikuni carb. Does anyone know what size jets I need for the carb and where to get them?

MY 140 doesnt have any numbers on the jets. It has a 22mm carb.. But I was told the 26mm carb adds s lot to the top end of the bike.

Here's a link to a jet kit.
