Re: Back after top-end Rebuild 70cc 20" Lowrider
Bike looks awesome! I would recommend removing the rubber from between the motor and frame, it needs to be directly and solid mounted. You will find it drastically cuts vibration and I have seen pictures of rubber mounts actually causing the motor to saw thru the frame. As for jetting I found a bunch of good information on making that carburetor work well from the moped guys. There are threads here to as well, use the Google bar.
