You live and learn, as the saying goes.
As soon as I'd drilled it out I thought "Mmmm, that might be a bit big!".
When I had the clutch cover off there was a coating of oil cooked onto the inner cover and basket - it looks like it's been getting a bit hot in low speed tricky stuff, so I thought a bit more oil flow might help.
Looks like I'll stick to the stock size and maybe get a 0.50mm for extended offroad use.
KTM 990 rider and proud of it!!
950 adventure gone, but not forgotten.
