The best just got better!
Production of the Q-Matic series #7 has just been terminated and replaced with the new series #8.
The difference between series #7 and series #8 is the secondary drive pulley. All previous Q-Matic production units employed a 5" aluminum pulley, whereas series #8 will use a special steel balanced unit. The new pulley is balanced to 5000 RPMs, and is much smoother. Because of the additional weight the new pulley has transferred additional torque to the rear wheel and does slightly better on hills and heavier riders.
We spent time testing the special pulley on the Q-Matic drives using the HF 79 & 99 CC motors with outstanding results. We were able to do some minor testing on the Honda GXH50 motor, but we are currently running tests on the HS 142 motors to complete our research.
The heavier pulley stores more torque without affecting the revolution rate of the motor. We ended up with a little more torque delivered to the rear wheel and the motor still revs very quickly [unlike motors with the heavy clutch installed on the flywheel].
Have fun,
