Last night my bike fell over after I put it on the sidestand, and luckily I caught it just before it hit the ground and muscled it back upright.
This is the second time the sidestand has tried to collapse on me, and though I am aware of the problem and try to make sure it is always positively locked forward, it still seems to happen sometimes.
So I started looking closely at the design of it, and I believe I found the problem. If you look at the forward anchor point of the sidestand spring, you will see it is slightly aft of the sidestand when it is in the down position. This prevents the spring from pulling and locking the sidestand in the full down and locked position. You can actually pull the sidestand slightly back from full locked and release it, and it will stay there. On other bikes, the forward attach anchor of the spring is forward of the sidestand in the down position, so if you attempt to position the sidestand slightly aft of locked, the spring will automatically pull the sidestand forward to the locked position.
So it appears that Yamaha just did not do a good job of engineering the sidestand so it snaps forward into the locked position. I know some folks have ground off the stop, but that really does not address the root cause of the problem, which is the spring actuation.
I am thinking that if you could simply move the anchor point that the front of the spring hooks to forward on the bike about an inch, that it would resolve the problem. I am still trying to figure out an easy way to do that and I might be able to fabricate a new attach anchor that could be retrofitted to the existing anchor to facilitate repositioning of the spring. If sucessful, what this would do, is make the sidestand snap and lock forward (positively) automatically when you deployed it, like it does on other bikes.
Thoughts?
