Hi Trev,
Yeah, it's looking like a bit of a dead end unless I want to pay a fortune to import one from America! I've got a bit of a plan to machine something up that might work, I'll let you know if it does! Ah, if you have two now, can you help me with my front sprocket teeth count issue? I'm told a Beta sprocket will fit, but I don't know what number of teeth to go for. Also I'm not sure what chain size to go for. Thanks, Martin.
