stock or rejeted?

[IJG]

I upgraded a friends motor with an intake & exhaust,
What carburator can he utilize on the 6.5 loncin 196cc other than the stock ruixing?

If all you did to it is remove the air box and install a header the stock carb is your best bet with a rejet . You will not get any gain from using a mikuni or such with out more upgrades
