I was reading on another thread that one of the first things u should do is replace the bolt on sprocket. So what other options are there?

If you want to upgrade to a nicer cleaner looking installation go to Manic Mechanic's webpage on the right of your screen under the sponsers column .
He has some good replacement options . Or put your kit's standard sprocket on your back wheel , the correct way so that it is snug and runs true with the wheel , and moniter it occasionally so that the bolts stay snug , and go about your business having a good time riding . There are many ,many , bike builds using the standard kit sprocket . Monitering all the bolts in your entire assembally is a good idea .

Jims sprocket kits are really nice & make it easy to install a rear sprocket perfectly!!! But, "Yes", The stock sprocket & mounting kit works just fine if you install it correctly!

DONT use a coaster brake rear wheel. you could end up with a nasty ruined wheel if the bolts catch the brake arm like mine did. part bad idea, and part builder error... (i was too lazy to just remove the brake arm and put u brakes on it and now i need a whole wheel.... tire tube and all)

i have a coaster brake wheel and i have 1" clearance between the coaster brake arm and sprocket bolts. i have a stock sprocket too.

The coaster brake arm CAN be bent allowing further clearance from your sprocket bolt heads. However, the hole on the stock sprocket I got with my motor kit wasnt large enough to prevent the brake arm from rubbbing the inside of the hole where it is under the axle nut. I was lucky enough to have a friend with a metal lathe so we turned the sprocket to make the hole a bit larger. I suppose if you dont have a metal lathe available you could do it with a metal file or just down the edges of the brake arm where it fits up against the axle.
How well do the sprockets mounted on the disk brake mounts work? I have seen them advertised and they look like a great idea but a bit pricey. I have a traditional mounted sprocket and it works quite well for now, but they are never perfectly alighned and I atribute the vibrtation I get to this misalighnment.

The sprocket is not mounted to the disk brake boss (at least on my bike its not). If u could get a sprocket with the rmatching hole pattern I guess it would be ok.

I considered going the manic route but your wheel hub has to be truly round. My Schwinn's hub, on close inspection, isn't round but is gradually smaller in the middle.

My belief as always been that the sprocket setup (especially the stock one) has always been the weakest link in bike engine kits (except for those defective gear boxes on the 4 strokes). I wish someone would come up with an affordable mag type alloy rear wheel that doesn't use regular spokes and has a sprocket that can be unbolted and has different tooth options and bolts on with just 4 bolts and accepts a fat tire. It looks like the Chinese could whip these out at a small price. Even a cheapo metal would probably be superior in strength to spokes.
