Tried all the above
Removed all the rubber bumpers. This is good and will do no damage, the seat is actually easier to take off and on, a bonus. The downside, if you take off the two front ones on the tank itself, you do tend to slide forward onto the family jewels.
As for the side stand shortening thing, if you ride on the right, then yes, this MAY be a useful option, don't try this if you ride on the left, you may have difficulties picking the bike up
The camber of the road can hinder or help. Whilst in the states I always had parking issues, to me, the side stand was on the wrong side of the bike compared to road design.
I do use lowering links also( I am 5'4"), and have raised the forks through the triple tree to keep the bike balanced.
NOTE- The effect of all this(as well as a bash plate) means the ground clearance is severely affected. On corners, my lean in angle is dependent on road condition. If there are big bumps or potholes through the line, then I back off right away because if I am at extreme lean and hit a bump the bike will usually touch the ground, usually the bash plate, but sometimes the peg sensor, the result of this is that usually the back wheel unloads(and sometimes be airborne), steps out, reloads and kicks up, this can lead to a high side . This will happen more often than a normal height suspension, I have learned to compensate, but speed is affected through the corner!
Note - ALL of the above was with a fully loaded bike, metal panniers, top box, tank bag and extra camping bags strapped on wherever. Your results may differ.
