Cheers, nice to not be alone with the vibe issue. Yes been told by a friend that sync the throttle bodies help a bit, work shop job? Just installed foam grips which is my first farkle which I will try out shortly.
Did order a really tough gear rack made in USA which will look great.
Regarding break in, my B-King I broke in the Motoman way, this one will be somewhere in between, so far only used S mode and been riding it just "normal" and avoiding the same speed but varied the throttle through the gears.
Will dump the factory oil before 200 km (125 miles) and then dump next as per scheduled maintenance.
