<human>: Give me the gist of the text in a nutshell

A buddy of mine is on a bad path. We both own motorcycles. I have a Honda nc700x. He has a Suzuki dl650, but that's not the important part. He likes to go fast and do stupid things, ever since he broke up with his girlfriend of 3 1/2 years. Today we went for a motorcycle ride and we took a break in a scenic overlook parking lot and out of the blue he decided to try to do a burn out on a asphalt parking lot which has been seal coated so there is extra rock laying on it. His tire slipped then when all the loose rock was gone his tire gripped, he went into a wheelie but it was at an angle which then caused him to low side his bike. He was pinned under it. He is luckily ok but, his bike isn't. Bent handle bars. Badly scratched ferring. Broken turn signal. Bent mirror.  He got up and is happy about it. Now I mentioned that we were on a scenic over look... Which is perched up above a main highway and a river, so we're probably 20+ get up with just a measly 2 foot wall keeping him in the parking lot. Ever since his girlfriend broke up with him and he bought his bike he does dumber things every time he gets on it and one of these times I'm afraid that he is going to do something, Seriously injure himself it worse kill himself while in right there and I'll have to deal with that. I'm not sure how to tell him he is being a fucking idiot and needs to stop these shenanigans before he hurts himself or worse.
<bot>: Buddy bought motorcycle and is doing stupid things and is on a crash course to injury or death. I need advice to get through to him.
