Not much too see but theres my short project thread on the whirlwind.
I think these bikes came with a torque converter (the pulleys) my set up lined up with the sprocket real nice....like it was supposed to be there.
Idk why the hm80 pic is all blurry but that pic is in the link too.
I got lucky with the lil' h35 motor.
I'm diggin the bare steel look but im hopeing you clear coated everything or are you going for that real rusty look.
