after being bummed out about breaking my clutch drum/shaft on my friction drive i finally came up with an easier to fabricate idea looking at my bike i noticed a rare feature most bikes dont have threads on both sides of the rear hub allowing 2 freewheel coasters to be installed at the same time currently my bikes set up with the pedal powering front sproket and chain all on the left side leaving my right side open for an additional freewheel direct chain drive from engine shaft to freewheel setup no clutch needed wich seems to be the #1 problem mounting the HF 79cc up all i gotta fab is a way to mount a 44ish tooth front sprocket securely to the HF 79cc drive shaft via adapter and wallah a HF 79cc ride that can be pedaled along at idle and let off the gas downhill with no need for a clutch or engine stop switch to mount the engine i would just drill 4 holes and put it on top of my bmp carrier having the engine more centered then a traditional friction drive would also be great to for added control and stability look at my attached pick for the dual hub threads to see what i mean
maybe you could even do a dual derailer shift hub setup alowwing to change pedal gears on one side and change engine powered gears on the opposite side
