phazer main jets

[motosled]

Hello, i'm new to this site but have had lil' yamy's for a while. 340 excels and enticers. Just bought an 88 phazer and got a DG pipe for it. The pipe paperwork recommends a 145 main but the parts fiche only has 147.5 as the next larger main jet. They are round but i was wondering if i could use the hex shaped ones? Also i have seen some 145 main jets for sale, listed as "large round" mikuni mains. So are the phazer mains large or small mikuni mains? any help woukld be greatly appreciated, thanks, Paul

I found a site that sells mikuni jets and parts. made it easy to order some jets and actually see the different types. pjmotorsports dot com.
