i never really understood why guys did that...i always felt better having the thing leaned over on the stand, rather than standing straight up - i feel like if it's pretty much straight up all it takes is one little knock to tip it over to the right...
The issue is when you raise the rear ride height, the bike leans sooooo far over on the stand that it becomes unstable and/or will no longer stand up on the kick stand. While raising the rear ride height often results in the desired handling change, a longer kick stand is needed. I went the same route as Nero on my M620 and my 748. My Monster will definitely not stand up on the stock kick stand by itself.
