My motorized bike stopped running on me while I was out on a ride and I tried to re Crank it but the chain just stops and my back tire does a burn out and it want go to Crank at all. I had to pedal it home. Any idea on what's wrong and how to fix it? I'm very new to this.

Sorry for the late reply... There's a few reasons the engine locks up one is the rings caught the port and/or it got over heated either way pull the cylinder off and take some pictures... So we know what engine you have
 
Riding my hyper cruiser,w 100 cc motor on it , I’m getting sputtering problems, she goes about 40 km, and it’s just coughing and sputtering???
 
As a rule I replace the mag with a 12v or fat boy one and the CDI with the tall tz one and the plug wire with an automotive type one with a boot on it... heat shrink connectors you can rewire everything with 16ga wires the magnet has an upgrade stronger one... You can adjust the timing with a shaved down key or a star washer with a tab bent over to hold it on... Ngk B7HS plug... Gapped at .028
 
The first 2 come from the same place the hex boot CDI is the latest one and assuming the new magnet is the stronger one the fat magneto from kings is the one I would get... These companies are constantly up grading and going in and out of business... But as of today these are the ones available

I found out my wiring was wrong,I had all ground wires hooked together, and learned that the coil black ground goes to the engine black ground, but the kill switch black ground shouldn’t hook up w the other grounds, so I filed off some paint, and black taped the kill ground to the bike frame, gonna go give it a try!

Could be a bad kill switch... Intermittent shorting... I got tired of chasing problems and go through everything... The challenge is to get it reliable check out LA hover on Utube he has a bunch of videos on the 100's

Ngk B7HS with 2 washers because it may hit the piston if you have one base gasket on the single piece cylinder...unless you have the 49mm steel sleeve 100 that's 2piece cylinder... Take some pictures of what you actually have... the 100's run hot so a B8HS in the summer 7 in winter
