I guess we all have some type of anxiety about the possibility of breaking down on our steeds. Considering that these bikes are hard reving performance bikes. I know i'm constantly listening for noises etc. Some examples that got my heart racing a little faster on a few occassions are....running out of gas while in the on position, or having my tank vent kinked You think.....i've finally done it ....only to realize that your problem is very simple. A quick fix & the rev limiter is pushed to the limits for the remainder of the ride as usual. I ride my 04 without any trace of mercy & it never ceases to amaze me. It is the toughest bike i've ever had & demands to be tortured !!! Why do i even question it If it blew up tomorrow it would be of no shame. This machine is awesome I have 1700 miles on it....& 1200 of those were at the rev limiter. Three back tires, one front, 4 oil changes & two valve checks [in spec both times}. Anyone else here have this feeling of questioning there steed & its reliability ???
