I've already posted this on another site, but maybe some members here will be interested.....
-Just got one of China 66cc motors and looking at the flimsy stock mounts, I decided to make them better. At the same time, make them rubber mounted and adjustable side to side.
This is what I came up with for now, I would've made the mounts out of aluminum but steel is more forgiving in the first design, besides my aluminum TIG welding sucks.
The rubber inserts are front sway bar link rubbers from a 5litre Mustang turned down to fit. They are made of polyurethane which are quite hard.I may use a softer rubber later.The feel gauge(0.004) in one of the pics. is the clearance so the motor can move up + down but not twist from side to side. The weak spot is the stock 6mm threaded mounting holes on the motor, if they strip out I'll helicoil them as there doesn't seem to be enough meat for 8mm maybe 7mm.Hopefully this design won't throw the drive chain, then a head steady will be necessary.
My rubber mount design is a flagrant copy of the ones on the Norton Commando motorcycle, so feel free to use any and all of these ideas. I have yet to make the front frame clamp/mount. By the way, that's a Creative Engineering & Design clutch housing, real slick
