I have a 97 xp with the 800, i have a set of 44 blackjacks, spec 2 pipe, and a 175 pound head, any jetting tips for these carbs... thanks alot, by the way im goning to run 50/50 93,110 oct.

Does your set of bj's have a third jet?

We had problems getting greens, bj's and redtops to transition onto the highs without jetting to the point that we lost power in other areas.

My friend has a set of 48 bj's with 3rd jet on a sst 800 and these run very well.

I think he was running something around this.

L:115
H: 135
80spring
2.3 needle

The 3rd jet supplies fuel at all throttle openings so that explains the low total jetting for an angry motor.

I would probably start around 120/120 with your setup and wind the hs screws out a couple of turns for maiden voyage. Then come in until clean.

I assume your running a remote fuel pump so start with 60 TO 80 RETURN JET.
