Fcr 39mm

Please help getting ready to leave on a long weekend, My FCR 39mm just showed up a 1/2 hour ago. Now with my mods, and no Lid on air box, I had been running a 195 main jet, should i start with a main jet that high on the FCR or not, It came with a 170 main in it, Just looking for a starting point.

Thanks in advance.

Colby told me to start with a 165 main and a 52(i think it was) pilot.I had a 170 in and it was busting out pretty bad on the top end.
