It all started Christmas of 2011, the day I get my BoyGoFast "80cc" (actually 60cc, called in 80cc. Do you guys call a 60c engine an 80cc, because in the instructions it says that that's what the motor bike community calls them?)
I managed to understand the horridly translated instructions, sometimes it would take a few mistakes to understand something, but all in all, the build wasn't that tough. There were no wiring diagrams or instructions, and that took more internet surfing. So then I get it running a few days after Christmas, and when I have some free time. Runs fine for the few times I ran it. The only thing I complained about then was the clutch, and how it over revved itself, causing it to shut off, even though I had adjusted the clutch. After about a month of test runs, maybe 2 months, I decide to go a 4 mile distance. A little over halfway, the rear sprocket comes loose, causing the master link to fly off, and about 6 of my spokes to pop. I walk the 2 miles back to my house, and take it off the bike. There it sits for another month or 2 while a find a good donor bike, one nice and strong. I install it, run it, and it started making a very high-pitched squeal, and would not run. After more googling, I found out the gasket wasn't tight enough. It wasn't because they weren't tight, it was because one of the head bolts. They hadn't even threaded it. This was where my dad and I had to decide, get an over-sized bolt, or get a new case. We decided to get a new case. Worst idea ever. We order one of around 27 bucks, plus 1 shipping, and another 5 dollar gear cover, because they left a loose screw on one of he worm gears, so it broke right through the case. Anyways, the case comes, and we take the motor completely apart. The first thing we noticed about the crank case was the head bolts being smaller than the original. We get all the bearings in, and put the crank arm and counterweights in, and guess what! It didn't fit! The case that was supposed to be the same as the old one couldn't fit the counterweights inside! But the horrors not over! My dad starts to carefully take a bearing out, and the case breaks ON THE OTHER SIDE of bearing, not even close to it! now were deciding what to do, because we've spend close to 200 bucks, and it's just not worth it. Moral of this story, even if you want a cheap, learners bike motor that has some quality to it, don't get BoyGoFast
