I would expect to get a *minimum* of 50k from distributor and SUs, and would
not be surprised at 100k with normal care and attention. If your
distributor has gone sloppy after 3k then either it was duff to start with,
or it has got very poor quality bearings and has worn - reputable supplier
or not - or it wasn't lubricated properly when it was first installed.
FWIW I find just a couple of turns on my SUs - both HS4 and HIFs - is enough
to move it from normal to either obviously too weak or too rich. Could be
you have the wrong needles.
