drive chain

[robert.fallis]

the drive chain from my motor to the bike , varies in tension and keeps coming off the large sprocket, its an 8mm chain, does anyone know where I can get a jockey sproket to keep the tension more even?

thanks

Here's two sources Bob:

Wiggle

Bikedock

These are made for derailleur point attachment, so you'll probably have to rig a frame clip to mount them. Hopefully they'll be wide enough for your chain.

Hello Bob:

Is this what you need?
hit the link to SJS Cycles (there may well be other suppliers):

You may have to enter "Chain Tensioners" in the search box under "Transmissions".

I think your chain will be 3/32 inch. Cycle Chains and their pitch have remained steadfastly imperial I think.
