I just finished reading this entire thread since my primary concern with my 'new' used 2005 1300T is the cheap sidestand.
I know there are some Beamer bashers amongst these ranks, but my 13 year old K75S had an excellent sidestand. In comparison, it allowed the bike to lean over a bit further (and the bike weighed nearly as much), it fully extended farther forward, had a larger base plate, and the footprong was almost part of the baseplate, making it almost impossible for the sidestand to sink completely into soft asphalt, gravel or dirt. Conversely, this FJR sidestand holds the bike at too vertical of an angle, doesn't extend far enough forward, and without something to widen the footprint, it's just a matter of time before it sinks into hot asphalt. Needless to say I'll be using the centerstand most of the time.
Over the years the main thing I paid close attention to with motorcycles and sidestands wasn't leaving the bike in gear or using the kill switch, but always pulling back on the bike to make sure the sidestand was fully extended, and making sure that if the bike wasn't level that the front end was slightly uphill, increasing backward pressure on the sidestand.
I watched a small mechanic easily put my 1969 T120R Bonneville on the centerstand, after I had previously wrestled with it during my first rookie months of ownership. What I learned from him was how to use my body weight and leverage to make the job easier. Left hand on the left handlebar grip, right fingertips in that narrow FJR gap meant for this purpose, lowering the centerstand until it touches the ground with the ball of my right foot, then in one steady quick motion - step down with full body weight while lifting the bike up and back. Once you get that 'rocking' motion down, it isn't that difficult to put a heavy bike on the centerstand.
Now for some wild assumptions and speculation.... IF the #1 cylinder is the main problem "ticker" as some threads here indicate, AND the #1 cylinder is on the sidestand side of the bike, AND the sidestand is always used, COULD there be a correlation?
