Default Less than 9 tooth drive sprocket?

Hey,
Has anyone seen a web site that sells a drive sprocket that has less than 9 teeth?

The reason I want to know is because I want to give my bike some more torque for hills by downsizing the engine sprocket, but the smallest one I can find is a 9 tooth and I dont know how much difference a 9 will make, rather than a ten

If there is a site out there that sells a less than 9 tooth drive sprocket...please share!

Thanks a mil!

Howdy BikeW/M. I dunno, never saw any. For better hill climbing, wouldn't just a larger rear sprocket do the same for ya? Cheap and easy to find.

Either way, you will trade speed for power. Unless I am wrong, in which case you won't. But I am not, so you will. (LOL, lost my self there) But some one will correct me if I am mistaken. But I'm not. if I'm am...

hehe, I'll stop now.

Wow, thanks BWM. Would be a whole lot easier then swapping out the rear sprocket.

Hey by the way...I just found an 8 tooth...here it is!!!
(The pic is the wrong one but they have that same pic for all their engine sprockets...)

This sprocket will give your engine excellent torque for steep hills!

I don't think either one of those sprockets will work on the engine...
I believe the SBP sprocket is for the jackshaft & not for the engine, & the other probably won't fit without modification.

Like me & 2door said in the other post exactly like this one... It's a lot easier to just find a larger rear sprocket!!
