Today After doing 850KM on my YBR I decided to cross my RPM limit from about 5 to About 6.5....The bike ran good, can easily touch 75Km\h at 6.5RPM.....But I observe that the 5th gear is not meant for acceleration...5th gear is only to maintain good speed with a little bit of acceleration...Tomorrow Insallah I will complete 950KMs at @6.5RPM and than First tunning.....Only thing I want is to have, afterwards is a good & quite sound, as I really don't like the sound at the moment is should be more quite, more like a gentleman...Fingers crossed!
