I have no idea what the stock spring rate is for the ER, as it doesn't appear to be in the shop manual, but I would guess it to be over-sprung like the Ninja 650R is (an insane 1.2Kg/mm). I guess that they did this to hide the fact that they used damper rod forks, in what is nominally a sportbike.

Bikes like the SV650 are grossly under-sprung. They're perfect if you're a 120 pounder, but not so much for anyone else. My '00 VFR800 had something like 0.75 Kg/mm springs. I needed 0.95, and that was for a plush sport-touring style ride. I don't think that the more recent VFRs have stronger rate springs than that.
TOTALLY agree with getting springs, I have done so on almost every bike I've ever owned-including cruisers. That's a couple hundred bucks max... Spending 2k on suspension on an old bike... Well, what about the brakes? Transmission? Unsprung weight? Rake and trail? Total bike weight? There have been advances in more that just hp bro... My bike now kicks the crap out of my old FZR1000 in every category, seriously.
