@nom125 congrats bro...you shown us very artistic n creative pic of your new bike
i need to add up lil thing, maintaining the speed or the r.p.m wont be the real task
you can accelerate bike in first or second gear till the mid rpm,s but dont go above the mid range
on other side do not try to maintain on fix speed like 40 or 50 for long time,
go for different kind of revs while riding, ride low n then ride lil up, the main objective is do not ride at fix speed and the rpm,
if you go for fix speed n rpm then your bike,s engine would use to of cool n calm kind of behavior, and after completing running when you will go for lil high rpm,s then you will might have to face problems, hope for the best
