You seriously need an explanation of why parts for a Whizzer cost $700, lol? I've been to Jay's house, he's got non-whizzer bikes with more than $700 in them. Heck, my 98cc Lifan bike cost $800 to build, and I picked the engine up from Jay used for $50. And since I don't know where to find an original Whizzer, I priced building one through sportsman, and we're talking around 3 grand. The best bikes ain't cheap unless you have a lot of spare parts on hand and serious fab skills, lol.
