Given up trying to jet the 25mm phbl just cant get it to run right at all !! thats on my LI which has been re-bored to a 175 with JL3 pipe ! so ive got hold of a 28mm dell, the jets that are in are as follows ;

x7 needle
AV268 atomizer
50 pilot
45 starter
main 120

some advice please on whether this jetting looks about right for my set up !

id try an AV264,x13 needle...........
main 125 then work down a little if poss......
pressuming your running it open that is..............

was thinking of the possibility of using a filter ! what would the difference in jetting be if running with a filter ?

With Ramair I'd go for what Sean said but with 120 main (might even have to come down to 118 or less if too rich at the top. I've just started my tuned (torqey not balls out) 230cc iron barrel and it's too rich with a 128 (on a 30PHBH)

Thanks for the advice !!!
