Re: Narrow sprocket and chain- Not recommended here
I put a shift kit on my bike and it came with a regular bicycle chain. The motor sprocket was too wide and wouldn't fit between the links of the chain. I used my belt sander and let the sprocket spin while I thinned it out to keep it all even. After thinning, the chain rollers fit all the way down in the valleys of the sprocket but the teeth were still a bit too high. 2 links would go on but the next roller wouldn't clear the top of the tooth. So I spun it again while grinding a little off the tops of the teeth. then beveled the top corners a bit. I works just fine now.
