Good information chaps, thank you.
The chips have occurred in the last twelve months after thirteen years of spirited riding since the last rebuild so I'm impressed with that.
All the tranny oil changes in that time have produced only a black slime on the magnetic plug.
I would imagine a rapidly increasing amount of chips would result from all the bearings after the first bearing started to let go.
300 rpm 'eh? That's just a nice amount I think.
I have always noticed that fourth and fifth are reasonably close together so the taller fifth may bring the ratio more into line with the rest of the gears.
Out of interest, I have ridden an 1150 gs and found the ratio between fifth and sixth to be just a little too great. I wonder if I will experience similar with the taller fifth.......
