Regrets if this information is redundant, but--a friend with a non-helper-lever center stand tilts his KLR650 over on its sidestand, raising the rear wheel, then deploys the center stand with his foot, allowing the bike to return upright as the weight is transfered to the now extended center stand. Kinda hard to describe in words, but--tilting the bike initially onto the side stand provides enough clearance to lower the center stand; when the bike returns to a vertical position the machine is suspended on the center stand. This technique appears less physically stressful than lifting the bike onto the center stand straight away. Again, regrets if this information is repetitive or obvious; offered constructively in case it may be helpful. I have a Happy Trails adjustable center stand with assist lever on my bike; still, getting the rear wheel off the ground can be a challenge.
