So last summer I saw a video about a motorized bike build on YouTube. Seemed simple enough. Just slap that old 4-stroke on there and bam, cheap motorcycle.
I found my dad's old trash mountain bike and bought the standard Huasheng 4-stoke all in one kit on Ebay. After putting everything together, making sure the chain was tight, and hooking up wires and fuel lines, I was ready to ride off into the hazy sunset of a hot South Texas suburb.
I hoped on my glorious invention, settled back into the insanely small and hard mountain biking seat, and gave the throttle a twist. (had already let it run idle and reved up a bit for an hour to break in) The first mile went well until it didn't. Cruising at maybe 20mph down a flat road was all fun and games until the drive chain committed suicide, with no warning whatsoever the chain ripped in half and wrapped its self around the rear sprocket. This happened about 5 more times, with many attempts to figure out the problem. I checked the chain tension, all good there. Realigned the rear sprocket? Yep... many times.
Eventually I found that the pineapple mount on the rear wheel was the problem child of the whole build. It would come loose or shift no matter how tight I made the nuts, or how much thread locker I put on it. The solution after that was to buy an $80 CNC adjustable sprocket adapter that would clamp onto the rear hub.
That expensive part turned out to not fit my rear hub as it's not a standard hub size. So now I have an expensive paper weight, can't return it with out paying almost more than its worth in fees and shipping. So now I'm left with a bike that's been sitting in the garage taking up space for months and I only got to ride it a mile or two before it died. It makes me so mad because it was so much fun for that short time, and I have so much money put into it just for it to sit and get dusty.
The whole community seems so great, and one time I broke down on the side of the road some guy on a 2 stroke cruiser stopped and helped me unwrap the mangled chain.
So yeah any advice would be greatly appreciated. I really want to get it running, but don't have much more money left to throw at it. Not that I did in the first place lol.
Bad picture, sorry.
