Jetting for a 70 cc

I will soon be getting a 70 cc polini sport kit and i just wanted to know roughly around what size jets i would need to get. I currently run a 70 on my yasuni z pipe on my 50 cc

 

Id get the 75-98 jet set if it was me. Probs not the best idea to buy single ones for a big bore kit as it could easily be far off

 

Im running a 64 on my nrg with a pipe an thats rich! Haha i need to jet for a 70 too might see what is in the carb im getting an ill tell you

 

I don't want to hijack this thread but I have a typhoon with stage6 sport pro mk2 70cc kit with a pro replica pipe, carb is 17.5 with 72 mainjet. Is it ok?

 

ok thanks ramo
