There is no doubt correct clutch adjustment is crucial to the ease at which gears can be selected, but is is near impossible to get a perfect set up. The best you can hope for is to minimise clutch drag. With the bike running, in gear and clutch pulled in fully you should be able to stop the rear wheel rotating with light hand pressure on the tyre, and it shouldn't be too keen to start rotating again when the pressure is released, although it probably will.If there is much force trying to make it turn the drag is still an issue and if it can't be adjusted out then possibly the plates have warped. I find 15/40 oil in the primary helps a lot,warm or cold. Too tight or slack chain tension can also affect the change and I normally run mine between 35 and 45mm upward movement on the bottom run. 1 notch on the snail cam seems to make 10mm difference. The book states 20-30mm but this in my judgement is far too tight. There is also a knack to gear changes, be positive, not too quick and let the gear lever return between shifts is my best advice. My box also took around 5000 miles before I judged it to be fully loosened up.
