Quick back story: I purchased my 11 year old son a Coleman CT100u for Xmas. He previously had a Razor electric bike that did 12mph so I could just ride my mountain bike with him. With the CT100u doing 20mph stock, I figured I needed something to keep up with him so I bought a CT200u-ex for myself. I recently did the governor zip tie method on both. My son is super skinny so his jumped up to 32mph, mine only went up to 25mph (I'm not skinny), so I added a new carburetor, a straight pipe exhaust with muffler, and an air filter. Now mine does 34mph.
We were riding the other day for about 45 minutes, when we got back to our street, I went full throttle for about 8 or 9 seconds, and just as I reached my house there was a loud pop/explosion, and the bike shut off. I tried to restart it a couple of times with no luck. It had been a long day so I didn't troubleshoot it too much. I'm a Biomedical Engineer (I repair medical equipment), so I'm handy, but I've never learned much about automotive/bike engines.
Where should I begin troubleshooting this issue?
