Fueling/run ability changes?? Also how many miles did you get out of your tires?
The bike feels the same to me. Top end feels just as strong. the bike is definitely running leaner. There's more popping on decel. I plan on getting a bazazz system to clean that up though.
I'll be posting another thread with my tire review but I've been happy with them. So far I have 5200 miles on them including a track day. They have never once slipped on me and I run with traction control off. I'm thinking I can stretch out another few hundred miles before they become too dangerous for me to ride them. once that happens I'll post up my full review.
I already bought a set of bridgestone S20's to replace them. the price was just too good to pass up and they've gotten decent reviews so I wanted to check them out.
