Well, I tightened up my front 1 full turn this morning, just a small change, probably it's better to make bigger changes to get more of a feel for what the difference is--a bunch of small changes with time in between is kind of like boiling a frog in water where you turn up the heat very slowly, you get used to it so slowly that you don't realize what's happening...
Anyhow, I was really pushing it on my ride home, doubled back and did the 3 miles again and dragged the peg on one of the corners. I could have stood the bike up a little more, but only had jeans on, no pucks. The extra turn on the front forks was nice, but if I had to guess I'd say I don't think it helped me go that extra 5 mph around that corner that dragged the peg. It was probably more just mindset and a desire to push harder.
Also, DaveM and Dolson are right, not the "no drag" nay-sayers. The Sprint's limit is the 3/4" hero blob on the peg--you can't push the bike harder than that. If you're wearing puck sliders you can stand the bike up more and drag your knee instead and if you have outrageous skill and puck sliders you can get the bike and you're knee and elbow down and you're still back to the peg limit.
