Super Jet mikuni sbn 46 setup \ jetting

[xavix85]

hi. i have 2008 sj with factory b-pipe and mikuni sbn 46 single carb.
it seems to run little rich at 0-1\2 throttle.
i didn't open the carb yet to see what is the jetting right now but if someone have a good starting point for me i wil really appreciate it because i need an intentional order to have jets and parts over here.
i live at sea level temp is around 90-100 degrees.

Im interested to hear about this as well. Are you running this carb on a wetjet intake?

for a 46mm on a ported 185 psi 61x/61x
I am running 120 lo, 150 hi, 2.5 n&s, 80 gram spring
May be a starting point for your tuning

Any idea what you have for pop off pressure with that setup? I was told to try not to go above 2.0 for needle and seat to prevent leakage/dribbling

not exactly, I got the specs from the motor builder and it runs like a champ
he said it would be around 28
never had an issue with fuel dribbling

Sweet sounds like a giod starting point
