@HydBiker: After reading about yours&Archi's&many other guys'problems, I am more or less coming to a conclusion that the R15 is not like what we read about before buying it. In the sense, we thought it was a machine to be ridden hard&kept on the boil most of the time. In other words, a machine that supports the fearless. Unfortunately, it seems like we need to treat it like a baby&curb our desires in the interest of maintaining the vehicle for a long period with less hassles!
Last night I went for a ride on KBR Road with a pillion&by the end of the road it had only reached 107kmph, with shifting at around 9K RPM!

I may consider selling it off if the Ninja comes in soon enough
