I have no trouble taking off from a dead stop on my cruiser with 66cc slanthead with 41 t sprocket without pedaling at all.
These engines have a LOT of low end torque for their size. With a little finesse, it's easy to feather the clutch along with low throttle and engage the clutch early at low RPM , then smoothly accelerate.
So what if the clutch pads need replacing early, they cost about as much as a McDonalds meal :~)
I never pedal, unless a cop is watchin' too hard
