fuel jetting question

just picked up an 04 blaster that has a toomey pipe and no air box lid. Runing at sea level. What size jets should i be running for the pipe?

360 main, and i guess 2nd or 3rd clip on need

myne is setup like this and a 360 is not too big for the replies
top end runs strong
 
i run toomey and uni air filter with a 290 but my elevation is alot higher jetting is trail and error because of the fact that elevation plays a big role in it..its better to start rich and work down till u get it just right... i know toomey sends a 310 with there b1 kit thats where i started and it was rich so..maybe this will help ya pce
