I have asked this question before but have yet to receive a answer are the cranks balanced? ZTMoto IM70 Iron Maiden - Performance Minarelli Vertical Iron Cylinder 2 Stroke Motorized Bicycle Engine Kit - 70cc Bike Motor
Are the cranks balanced? I feel more people would buy this engine kit if they knew the cranks were balanced as description doesn't mention anything about if the crank is balanced or not and no Minarelli engine is good if it don't have balanced cranks because they vibrate like crazy and you can't hit high rpm's without balanced cranks and upgraded bearings and viton seals not to mention a heavy duty clutch spring is a must so that the clutch don't slip from all the extra torque people would even pay a higher price point if you added those things which aren't expensive to add
