Thanks, Beachcomber.
I have been riding my K100RT for some time and felt that the bike was insecure in cornering. There are many explanations for this -- poor tires, improperly tuned suspension, bad road conditions, and/or poor driver. The tires are new; their alignment is correct; I drive city streets and highways in good conditions; I know my driving skills need improvement and I acknowledge that that is part of the problem.
I was thinking of tackling the suspension aspect and read online of the myriad ways of tuning a suspension. However, I see that these techniques only apply to late model Jap bikes with dial-in adjusters and not the K-series. My biggest hurdle is like the OP, not knowing what to expect from a perfectly setup K-bike suspension because I've never ridden a K-bike with perfect suspension. It's hard to determine if the current components on my machine are worn out and need replacing or whether they are badly adjusted because I have no reference point.
So, before I tear into the forks and change components seeking suspension nirvana, I will take "Ease Street". I'll measure and set rear sag with my current rear shock, dial damping to mid-way and see if the situation improves, degrades or stays relatively the same to today. If there is no change, I guess I'll consider new shocks and springs. I've had the same suspension components in the bike sine I bought it 13 years ago (and I suspect they were on the bike for some time before then).
I look forward to seeing the progressive springs and rear shock sets that Realm plan to develop. I would certainly purchase a set knowing that they match and complement each other.
Cheers,
