Like everyone said , correct tire pressure and a few heat cycles should even out a flat spot if the bikes been sitting . But if you do have a flat spot you should feel it more than hear it . Do you notice any chatter in the front end or just a strange noise ?
one thing that you should be more concerned about is if the front tire was on concret. i've heard that having the rubber in contact with the concret for an extended period of time will cause the rubber to harden and fatigue sooner.
if i were you i'd mark the sidewall with a grease pencil and keep an eye on that spot.
Hi all, apologies in advance for the negative 1st post but i have a 2003 RR which wouldn't start although fuel pump was ok etc just span really fast on the button but wouldn't fire. Turns out cylinders 1 and 4 had 40 psi and 2 and 3 20 psi so engine pretty well toast although was running fine...
