Hey everybody! I got some new tires today! Michelin Road 5s to replace my Dunlop Sportmax. Rear was already wore in the middle lol. The tires seem great but my acceleration seems to have slowed down? It almost feels as if the bike is now stock instead of set up with my EJK KN filter and slip on. (yes there was a noticeable difference! hahaha). The one thing they noted was that my chain was way tight so I guess they adjusted it accordingly. Could that adjustment and the new tires have anything to do with it? They recommended a tire pressure of 31F and 36R. I'm just not well versed in this subject and everywhere I search doesn't give me the answers I'm looking for. My guess would be more rolling resistance with new rubber? Give me your opinions! Thanks in advance!
