Hi Scully,
is your question still relevant to your current situation?
You asked if you can buy the water pump seal rings an the clutch needle
bearings after market.
The seal rings are no standard parts. That means you can buy some with the right diameters, but the original Husaberg seal rings have got
2 seal "circles" (sorry don´t know the excactly description for that, hope you know what I mean), and the standard seal rings have only one.
I could tell you what kind of bearing there are installed, but I have to know the diameters, I can measure them at a replaced transmission shaft and clutch hub I have got in my garage. So I can tell you later.
greetings
