My new Y Zinger

Just took a ride on it after cleaning the carb.A little scary ridding something that small at speed and hitting dips and bumps. Being so cramped up on it you feel like you don't have much control.ran pretty good.
 
video!!!!

I like it for $65. When I was little my dad had a suzuki 70 like that. We ran that thing like a dog and when it stopped running we pushed it around the yard. I was a blast.
