Rear sprocket options

Re: sproket problem

If the chain on the china engine fits your sprocket that you want to use and you have a way and means of drilling it to fit the china rear sprocket set up/ mounting rags and metal backing plates, then yes it will work. You will be able to climb some steep hills with that set up, not much for speed though.

I took off the crank off an old Mountain bike and pulled the sprockets and used them for the rear sprocket.

Thanks Fairracing for the pictures!

Yeah I did not have any $$$ for a sprocket so I just used what I had. I am using a #41 chain and the rag joint set-up to attach it to the wheel.
 
Hey Fairracing,

How well does the "rag joint" work with only five bolts in there? I have the chain rings to do the same exact thing and am in the middle of making metal plates for the outside rag right now. If yours works well with just the 5 then I'll do that then.

It worked just fine, just use some fender washers on the back plates.
 
Fender washers in lou of the back plate or in addition to the back plates? Would you mind posting a pic if you have one? Thanks in advance.
 
I think I understand now. Use the fender washers on top of the plates to apply pressure to the areas where the bolts were left out. Sorry about that.
 
thanks guys cause im in that same boat i think ill try that way jus have find a way to attach the sprolet to the back wheel.
 
Rear sprocket issues

Would anyone have any ideas on hot to mount a front sproket from a bmx on the rear wheel for a rear sproket . All pics and leads appreciated..trk
 
Re: Rear sproket issues

it can be done and theres people on here atleast 2 that i know that have done it.
you may have to drill holes in the sprocket and you will be bolting it to the wheel.

if you already have a 44t sprocket on your wheel but you want a smaller one right? for more speed.
lay the your 44t sprocket on top of your bmx sprocket(yes you will have to take it off the bike)
and center the middle hole,using a marker mark a dot threw all the 9 holes of the sprocket
take your bmx sprocket that has 9 dots on it and clamp it to some workbench and use a drill with a metal drill bit(the same size as the bolts that you are currenty using) and drill out the 9 holes. now you can mount it where your bigger sprocket was.

but you know that you can buy diffrent size sprockets and they dont cost much and are stronger.
