I've finally managed to get my gearbox to work smoothly, I was getting really fed up with the stupidly clunky gear change on my bike so decided to have a look inside the clutch to hopefully find out what the problem was. If you look at the clutch you can see the oil holes at about the 4 o'clock position. I drilled the additional holes every second tooth, one near the base and one near the middle.I've only covered about 600 miles so far but the difference is amazing.
I'd advise anyone against reducing chain slack to that extent. The original manual spec was 50 - 55m but Yamaha reduced it to 45mm after a year or two of the Fazer being on sale. Any tighter than that and you risk causing damage to the gearbox internals, particularly the output shaft bearing.

I think the best way to check the chain is not too tight is to make the adjustment then get a couple of mates to sit on the bike.
