DR650 fumbling at mid-range at height?

[Monstaman]

Make sure you wind the mixture screw back in half a turn from best idle.
It's too rich otherwise.

Ok, quick skid around the streets and she runs ok, ned to get up to a great height and try her yet.

Have done the mixtre screw turn and will see how she behaves, gotta take into account we are at 350 metres here so we are on our way up!
