Smack the float bowls with the plastic handle of a screw driver first,might just be stuck float,happened occasionally on older bikes,especially if sitting for a while,worth a try before dismantling some rather tricky carburetors,then ride the crap out of it if it works.Floats don't come out of adjustment very often,probably a speck of something between needle and seat,corrosion between the float pivot and pinot deteriorating Viton rubber tip on needle. Hope this might help,scary thing when gasoline is pissing all over the bike! No holes or splits in fuel line up by carburetors??

Prolly good advice, I already got em out tho and since Im planning a RTW (leaving in march) I have decided to go ahead and have em ultrasonically cleaned and put new o rings in all around... Floats need to be at 15mm right???

Float height

If your floats are at 15 mm then thats why you are spilling fuel. 3mm to 4 mm on the float height.

Yesterday I finished repairing that fault in an SE, not difficult but laborious

no o-ring or needle damaged, just a bunch of crap inside carburators

good luck

OK Carbs clean leak stopped. Now since I put the carbs back in its idling at 1100 1200 so thats good but hearing some loud backfiring pops every second or two. Is this a mixture or a sync issue?

The link you had questioning 15mm also has another link going to a 950 specific carb:

since this happened right after you put a new pump in, I bet you left some dirt or something in the lines after the pump that got stock at the float valve. Glad you fixed it. Those orings will come handy later.

For the backfiring issue. I put my money on incorrect idle mixture screws (IMS) settings. You must have tightened them all the way in or something like that.

is there a standard setting for the IMS like 2 1/4 turns out from all the way in?
