Could this cause a lean condition? **pics inside**

[Danny Kay]

Check these out, one carb (the first one pictured) is running lean after i installed bpipe, head, and MSD. Im thinking the extra demand for fuel might have cause a allready present problem to immediatly worsen. the dirty carb is too lean to even ride. Could this gunk cause it? And what can i do to correct the problem? Any ideas? The second carb pictured is the carb running right.

No, probably not.

matt, any clue as to what i should check next? The internal filters looked fairly clean.

Check popoff pressures of both carbs, and make sure they are tuned equally. Clean the fuel lines.

is a popoff guage somthing i can pick up locally? Im a carb newbie. thanks for the suggestions.

The front carb (dirty one) seemed to lean out more as i richened it up? Like the first carb (rear) was stealing all its fuel, is that possible? I was making equal adjustments to both carbs, at the same time.

My ski after bpipe is doing this too.My carbs are clean,but the rear is to lean,both set the same.Good Luck

always make the pto (rear) carb a little richer.
that side of the motor atkes more lugging
that is why when a motor leans out and fails it is almost always the pto cylinder that goes first

its my front carb that is leaning out really bad. Its like there is only enough fuel being fed to the carbs to fed one of them. No clue what to do, guess ill give i try what matt said.

looks like you got water in it. make sure your return isn't clogged in the cover, it's only a little tiny pinhole. put new fitlers in it, they catch everything and the little stuff can clog them up real easy.
