QUAD. EXTREME VIBRATION FROM ENGINE

[justas696661]

Hi everyone , last time i was in this forum in 2010 so it's good to comeback :)

Now i have this atv 250cc Amazing-Quad-Bikes-for-Dealer.jpg1.jpg

and same engine like in picture

Vibration is so extreme that exhaust holders breaking. plastics braking.... This engine doesn't have balance shaft ? that's the reason ?

anyone know where i can buy 250 -350 cc engine with balanced shaft ?


................these engines sucks.... why they not constructing it with balanced shaft......
