About two days ago, I was riding my bike in my neighborhood. I had just installed a twist grip throttle off my friend's bike on to my bike. After installing it, I went riding. I was going down a hill doing about 45(I knew I was dead wrong for going that fast), and at the bottom of the hill was a turn. So I got off the throttle and hit the brakes. But something was wrong. I was on the brakes but the bike was still accelerating in the turn, the bike was doing about 25. And in the midst of me turning, the bike threw me off the bike and slammed me to the ground. When I hit the ground I was sliding and my left foot had hit the ground, but the side of my foot gripped the pavement and foot went under my left leg and twisted. So after laying on the ground and cursing for five minutes, I got up on my severely swollen and sprained ankle, grabbed my bike and limped home. After I got home I took the throttle off and inspected the throttle internals. What my friend failed to tell me was that the throttle was almost shattered inside(don't ask me how.) This explained why the throttle hung open some. Later that night, my ankle swelled up to the size of a softball and it was hurting, I didn't tell my mom. But my brother snitched on me and both of us ended up in the hospital(he's sick). Now with my ankle still about the size of softball im living just fine. But take this from me: INSPECT UR THROTTLES
