jetting conversion?

[beaten blaster]

my buddy has a blaster he is trying to jet,we both cannot find any info online for stock mikuni to 30mm oko..were trying to find him a good spot(ballpark) to start. his mods are fmf pipe,bored .50 over,32:1 premix,open airbox with outerwear,and unifilter, we are at 300 feet above sea level if that helps also. i'm stumped i cannot find any straight foward info.thanks everyone

no need for a conversion, although i think there is a chart on here somewhere ?
there is plenty of 30mm oko info on here to get you started........

Very roughly a kehin/oko main jet is half of mikuni , K 150= 300M

Oppisite for pilot K 50= 25M

so for the mikuni stok pilot is 32.5,so for the oko it should be at roughly a 65 or closest jet?is that right?i think the oko comes with a 48 pilot(stock)

absolutely wrong, a 65 pilot is way too large for any carb on a blaster

blaster stock carbs run fine with the 32.5 pilot for 90%+ of applications, and between a 230 and 330 main, depending on mods

the 30 oko, and most mid sized keihins, will need between a 45-52 pilot and around 145-165 main, depending on mods.
