STORY: so i've been having all of my problems with the back wheel of my bike. The first one was the brake arm was in the way of the sprocket. Bent it a bit and it was fixed. THEN the chain shredded through my rear tire and blew it up, (RIM COST: 45$, TIRE COST: 15$, inner tube cost: 8$) while i was doing 40mph. After that, i put a wood spacer behind the sprocket which WAS working until the clamp for the brake arm snapped and the arm swung around and BENT THE FRAME OF MY BIKE. NOW: Currently waiting for my caliper brakes for the front of my bike. Put a thinner rear tire on, which solved the chain crap. Also sanded down the wood spacer and painted it black. Waiting for harbor freight to get the heavy duty chain breaker in so i can trash the chain tensioner and make the chain the right size. took out the brake shoes in the brake so i am currently riding without any brakes and am in my back yard. Also going to buy a new brake arm and start fresh. I am also waiting for the brake arm extender from spooky tooth. PROBS: Some gas is spitting out of the air filter and the spark plug is black and wet. Going to deal with the spark plug until i have the money to buy a thinner fuel jet for the carb. FUTURE (2 weeks): going to have a boost bottle and new air filter. also going to have 2 equal size tires. Yeah, thats about it, lulz! i will update this in a few days!!!
