While repairing my primary cover I took my clutch out to inspect it since I was strange noises from the trans in neutral that go away when I pull in the clutch.

Did not find anything wrong with the clutch or clutch basket but while I was going through the gears I noticed I have some slack between the input and output shaft.

In 1st gear I can rotate the input shaft 45 degrees before the output shaft starts turning. This slack gets a little less in each gear until 5th where it is about 22 degrees of play.

Does anybody know if this is normal? If it is not normal would anybody have an idea on what the issue is? It seems excessive to me and is probably where my driveline lash is coming from.

I think what you are seeing as slack is the time it takes for the dogs to engage and meet-up with the next gear. When the engine is idling at 1100 revolutions per minute there isn't much slack but turning by hand at ~20 rpm it is quite noticeable. Each gear is a slightly different size and the number of dogs, the size of the dogs, and the space between them varies from gear to gear. That explains the difference between what you notice on 1st, 2nd, 3rd, and so on.

I'd say its a significant amount of slack. I got the bike put back together and in each gear I can rock the bike back and forth a few inches before I feel it engage the engine. This is much more than my Versys. Makes it a little difficult for smooth transitions from on and off throttle.

I hope someone else chimes in. What you describe seems about the same as I see on my M2 Cyclone. I don't notice anything odd about my on/off throttle transitions but I have nothing else to compare with.
