kinda odd running a two stage dry.

So you'll be way rich during the first shot so there's enough fuel for the second shot?

or

Sorta rich for the first and sorta lean for the second?

also why have only one on at a time? why not have the first on for the first stae and the second and first for the second stage? use small jets in both.

example:

stage 1 = sol_a = 25 shot
stage 2 = sol_b = 50 shot

vs

stage 1 = sol_a = 25 shot
stage 2 = sol_a = 25 shot + sol_b = 25 shot

Just go with a big wet shot, with a controller!

Running a 2 stage dry shot you are diffenitly going to run lean and have the chance of serious engine damage!
A stock fuel pump on a busa cant really handle much more than a 50 shot!

Thanks,for the input... fellas

1st stage At 30 hp (#32 jet) with a MPS Fast Fi unit the bike will run/be on rich side a/f wise. Purposely done to use in first gear,then 2nd stage50hp (#40 jet)would be ON from second gear - up on with a much better a/f ratio and still be fat/safe side.

MPS regularly uses a 43 jet with their FFI units with a 11.5 to 1 a/f ratio
