We have two mods on Cobra chassis, first is a KX65 13front 48rear and uses a 420 chain, now the one we are building this week is a RM85 from my google searches the rm uses a 428 Chain???? So who do I need to get ahold of to get a 428 sized rear sprocket for the Cobra axle hub. And what is a good starting point for gearing on a 85/90 based mod quad. Thanks got to have this ready by VA I hope.

Get a hold of Rebel Gears Tuesday. They should have the sprockets you are looking for. As far as gearing on our CR Mod 14/47 seems to be ideal gearing . I would start somewhere close to that and then tweak it to your liking. Just Google Rebel Gears to get their phone number.
