carb question

i have been looking at the 30mm, i've seen a few guys list them in there mod's, and i think it's kinda like the pipes, "anythings better than stock", dont know about the cable, but i think they take the same jets as the keihin's?? i've also heard dont order it from japan, it takes forever to get here
 
awk08 is right it takes all the same jets an cables as a kehein, thats what i had before i got my oko it was way easier than the kehein to get tuned in also. so far it seems to be a good carb i was almost done with the breakin on my topend when the weather got cold so i havent had a chance to realy try it out yet, but it looks to be a decent carb for the money awk08 was also right about the slow shipping from japan mine took a month to get here
