One thing I've been meaning to look into.
You can get a mixture thumbscrew from a couple of sources that will fit the Mikuni BST carb on a KTM 640 Adventure. I've been meaning to see if it'll fit the Mikuni BST carb on the Sherpa.
There isn't a huge amount of space to get to the mixture screw on the Sherpa, but you can loosen the carb boots and tip the carb sideways slightly to get to it. Easier to understand when you're actually looking at the bike than to describe it.
