KTM 950 Adventure Carburetors

Been quite busy lately with several different things both motorcycle related and personal.

Looked over the carbs on the KTM 950 Adventure.

Had decided to change some of the O-rings and the vacuum slides since there was a leak when brining it out of hibernation last spring, so ordered some parts and sadly parts arrived damaged:

But the place I ordered from are sending a new gasket kit (very expensive so wont accept damaged parts), but to not have to wait for parts Im reusing the damage membrane holders.

When starting the bike before draining the oil it was not running good at all so guessed something was blocked, first time I had the carbs all the way off the bike:

Used two trays to keep the parts separated.

Found some sticky goo under the diaphragm cover of the front carb and wonder if it comes from the crankcase ventilation, plan to just reroute that into a separate bottle and see how much if any that seems to come out of it.

Seems like one of the vacuum pistons was in a smaller plastic bag so it had a small kink from being a little compressed in storage but they both feel nice and soft so should work just fine:

And on the rear carb there was quite a bit of carbon deposits for some reason, know I had some serious backfiring a long time ago when the choke cable had not been fully seated and held that wide open all the time resulting in backfiring with flames up the intake:

Looked over all the jets and the one seen loose in this picture was blocked:

Used a plastic bristle from a dish brush to clean them:

These smaller membranes also came with the kit so replaced them:

And when changing the vacuum pistons make sure to get the lower washer on the needle out, both mine were stuck and needed some help with a dentist torture tool to come out:

Also adjusted the float bowls but forgot to take any pictures, went with 3mm above carb surface.

Lubed the cables, helpful tool:

Buttoned everything back up so the bike could be started without the airbox since I had unbolted the TPS (throttle positioning sensor) rather then undo the electrical contact so it needed to be adjusted.

Started up the bike, adjusted the idle and sync the carbs before adjusting the sensor, was a bit off at 0,726 V and should be as close to but below 0.6 at idle, once adjusted:

Undoing the bolt it can be adjusted:

So its a little closer to being ready, have started seeing some motorcycles out now the big paved roads are OK in the afternoons the cold nights freezes any water on the roads and makes for some really slippery ice patches and there is still plenty of snow in the forests.
