I took the float bowls off and they had small bits of tank rust/sediment/water in them, not a lot and not enough to block anything fully but enough to kill the main jet when sufficient pressure was pulling them up the spout.
Fortunately cleaning out the float bowls on a Guzzi is only a 5 minute job, given their outboard location - takes a bit longer on a Monster but then a Monster does have a proper filter so a less frequent operation.

At this time of year, are you sure its not carb Icing ?
A dose of ProFST in the fuel should sort that.
Back to the rust, it might be worth draining the floatbowls and seeing what comes out.
You may even have water in there, in addition to further rust sediment.
I might also be inclined to drain (or at least siphon and flush) the tank.
Again, you might even find water in there, perhaps from condensation during storage.
Anything to avoid having to strip the carbs out completely really.
Further along ..... fuel pump could perhaps be an issue.
I'm told that they don't like standing idle for long periods as the diaphragm can dry out and perish.
For my money, first job drain floatbowls, maybe also flush tank, and also try some ProFST.

Thanks!
Will do , I want to POR treat the tank this summer
She was on low fuel light so I reckon the fuel pump picked up all the crap
Wahts the best way to clean out?
