Big problem or not???

Question

i have just bought a yamaha aerox 50cc and i was test driving it today and noticed it will only go up to around 20mph? but sometimes it will go all the way past 40 i do full throttle it both times when i try to achieve maximum speed but i did notice if i was going 40 plus and when i brake it will not do 40 again unless i hold the front brake and pull the throttle all the way back then take off again? anybody know anything about this? it has also just had new pistons fitted aswell? thanks alot =)

Answer 1

It just got new pistons and you're going full throttle? Why not just run over it with a dump truck?

Answer 2

achieving max speed would be very difficult since you just had installed new pistons. your motorbike is still in its break in period so i advise that you ease down on the throttle for  a while. now, about your bike going over 40 mph, it would depend on riding conditions. are the tires well inflated? oil changed? wind resistance? road condition and inclination? not to mention that you just had new pistons fitted in.

Answer 3

The motor is spinning faster then you are going, My advice would be to not slow down, Full throttle all the time !!!!!
