This is true Erik....  When the primary component sag/preload of the 
suspension are setup correctly.  That was the point I tried to make.

You can induce a "pogo" if your rear preload is too soft, and the front 
preload is dead on.  starting off by fiddling with rebound damping might 
make things feel better (for a bit), until something awful happens, like 
you pack the coils, then have no suspension.  hence my original 
suggestion.  start with the primary component of the suspension...

Damn, I need to start drinking more pints and eating more fish and 
chips.  I am way off triumph's recommended rider weight...  heh heh

33% static sag is a fairly sporty setup.  25% is a bit cushy.  I usually 
opt for 28-30% sport / street riding and 33-38% track.

If you need more than 33% on the street, you are probably pushing things 
way too hard -- or you just like a harsh suspension setup -- when your 
bones get older they will tell you "hey, easy up on the banzai 
suspension settings, eh?"
