Hey TEX
I have a MAC shifter, and just last week, I noticed that it was getting harder and harder to put into any gear..
My problem was that the the top plate that bolts into the shifter base was a bit loose, and actually off centre, so the shift-guides were about 5-10 degrees counter clockwise, and although plate was loose, it was just not loose enough, so each time I shifted, I would be repositioning the plate with the shifter. (if that makes any sense). And the higher the revs, the more the vibration, the more the plate would shift..
Now, I don't know about the B&M shifter, but, if you've got a shifter-guide that is bolted down to the base, I'd check that for tightness..
If not, then, I have no clue!
