What is the easiest way to install the lowering links with the stock kickstand and no centerstand? I heard it is pretty easy if you stand the bike up and have someone sit on it and compress the suspension. Just curious.
you need to lift the rear of the bike, by the grab handle, or hooks inside the storage area, or (carefully) a floor jack. the swingarm has to be 'floating' so you can move it up and down by hand to pull the bolts out of the lowering links. not too tricky, just get the rear of the bike off the ground and take it easy. Break the bolts loose before you lift the bike.
If you are at all mechanically inclined, it should not be hard.
I had the rear and front lowered for a while. Did not like the handling at speeds above 185. I have since restored the stock dogbones and the front. I think the guys at suzuki with millions in research had it right the first time. It does look way cool lowered. But hey, it looks way cool at normal height and besides it corners better when it is at stock setup compared to lowered. I have been able to make faster runs on the mountain road with it at stock height than lowered.
I used a Heindl swing arm pivot stand to lift the rear and I supported the swing arm with a Pit Bull rear stand. I was afraid the backward leverage of breaking those suspension link nuts would tip the swing arm pivot backward so the rear stand protected against that too. The nuts are uber tight. An impact would be best but I'm sure you'd need to remove the exhaust to get a socket on the nut. I was able to slip a box end wrench on the nuts and use a pipe over the end for leverage. There is very little space between the exhaust and the lower nut. I removed the muffler hanger bolt and the exhaust fastener under the engine. That allowed me to flex the pipe just enough to get the box end on there.
I also used a jack stand to prevent the bolt from turning but I don't know if that was necessary.
