I believe the Mikuni pump is the base model DF52. There are variations of this pump with one, two and three outlets. If you look closely at the pump, you'll see there are two unused (undrilled) outlets on the back of the pump and 180 degrees opposite, there is the functioning outlet.
I believe the pump KTM uses is a single outlet variation of the DF52-136. The funny thing is, when you go to the Sudco site and look it up, it's the only pump they ask you to call on rather than provide a part number for a rebuild kit.
So... I suggest you call Sudco, or a Mikuni distributor in BC.

That's all I got,
So... how's tricks?
