Brought a yamaha fazer v2 on feb 8,2016.i was pretty much happy with my choice till a week ago.Since then i've been experiencing throttle hesitation at low rpms.Its annoys me a lot as i have been taking good care of my bike and i aint a rash driver either.Also i have already checked in with an authorised yamaha service centre nearer to me.They said that the bike is just fine and they didnt any find any problems.They also told me that the air filter and sparkplug are just fine.But till now ,i'm experiencing the same problem and i just dont know what to do.This is my first bike which i brought with my own money which saddens me even more.I'm just clueless as i am pretty new to biking.so please help me out guys
