Because I'm a bit of a miser and definitely not a wrench (oils changes & chain adjustments excluded), I waited until the bike had 35K miles to upgrade the suspension.
Oh my gawd!!! Why did I wait soooo long? "Oh...so this is what a bike is supposed to feel like" I told John at Jett Tuning. The bike is on rails and responds with excellent feedback. I can actually sense when the front tire is about to lock there's so much feel. And cornering? No more mush - just firm, confident and compliant!
Race Tech 1.0kg springs w/7.5wt in front and a new Race Tech spring on the rebuilt shock transformed the bike into something I never knew existed. Anybody with the same aforementioned disability I have that lives within a days ride of Camarillo, California should see him. He also created my Dyno map on pg 22 or 23 of the PCIII thread. Still smooth as butter from idle to red line!
