Look for a #43 chain sprocket...

[mudrinner4ever]

I'm working on a old mini bike/scooter that I'm converting to electric. I need some help finding a sprocket for a #43 chain. The inner bore needs to be 1/8 and somewhere int the 11-18 tooth range. I've searched google for awhile now with no luck. If someone could tell me what pitch the #43 chain is that would help a tone too. Thanks in advance and i greatly appreciate it.

I looked around and I guess it is indeed an odd size.

Maybe you could convert to a #41 chain and sprockets.
A new chain and a couple sprockets would probably cost about $40+ shipping from mcmaster.

That is an odd size. You may consult with these guys for some replacement parts http://www.mfgsupply.com/GoMiniSproc...on_id=68ZZRs2h

I was looking at switching out the rear sprocket but I'm not to sure on how it all comes apart. That's my major set back right now. I'm going to go look around at a few stores and see what i can come up with. I started to notice it was an odd size when NOTHING online had it.

Well If I remember right a #43 chain = a #410 sprocket. Here are a few links that could help.

Hmm, I must really have a one off part here. I searched #410 sprocket with no luck. Those sprockets you posted are to large unfortunately. I think I'll be figuring out a way to get that rear sprocket off and mount a different one.
