Okay, don't make fun of me if this is a stupid question, I'm new to riding, just got my bike over summer. Me & my friend were hauling ass down the roads at his house & I hit top speed on my 89 125 rm & she just shut off. She wouldn't start until I kicked her like 15 times. I don't think I blew her up because I just got her rebuilt not to long ago, she still runs too. Could anybody tell me why it shut off? I'm just curious.
