um ok you worked out that someone needs 105cfm carby, but how the bloody hell do you know which carby that is?

my GX setup revs to 6,400 in a straight line so you must be doing something wrong , (7500-8000 round corners)

just kidding, it gets bloody loud and i wouldnt do it often but it is definately possible, i also have a bigger cam and overbore (40 thou)

i had twin 42 webbers previously on the same motor and the SU's dont make the top end that the webbers did, but my venturis were too big in the webbers and it ran like crap under 3,500 so i took em off for the mean time
