I asked this once... I got not reply

I had .52 in my 12a streetport but they are way to big, so I've gotta figure out what size to go with.

Good Luck!

I used 60 primaries and 61 secondaries on my 650 DP for a monster street port before I went with the proform mainbody. It's all about trial and error. ! jet size can make a hell of a diffrence.
