<human>: As the title suggests, I'm outside working on our mopeds and he pulls up randomly. Keep in mind I've never seen this guy before in my life, never met him, and all I know about the former property owners is one of them was foreign and got arrested for attempted murder, the other was black and got arrested for drug posession/sale.
Anyway this dude hops out of his minivan, wife and kids in the back, and strolls up to me. Here's how the conversation played out:
me- "Can I help you?"
former landlord- "You guys work on mopeds, right?"
"well, yeah."
"can you fix my minibike?"
"erm, well..."
"i'll pay you for it. I just swung by and saw mopeds pulling out of here and thought I'd ask. I have it with me."
"Okay, well maybe i could take a look."
He proceeds to show me a crotch-rocket pitbike with a broken throttle cable. Any backyard handyman worth his salt could rig up a bicycle cable and make it work.
He asks me if they're still renting out the floors of my house as apartments and i say yeah, sort of.
At this point he tells me he used to own my house and the place next door. He also brags to me about how he used to keep kilos of weed and cocaine beneath the shed in my backyard. Then a wave of logic and "oh, shit" feelings washed over me as i realized he was asking these questions to possibly scout us out. We had like five mopeds in the backyard, an expensive laptop hooked up to a good set of speakers and a pricey amp, nice cars in the lot, and all sorts of tools and useful and shiny things lying around the yard.
So i immediately tell him i don't have time to work on his bike, stop by a bicycle shop and have them make a cable for him and please get off my lawn.
So everything out of our yard is cleaned up and now the bow is strung and sitting within arm's reach of my bed. Should I take any super precautions? This guy really scares the piss out of me.

Can you provide a brief overview of the text?
<bot>: The felonious former owner of my property asked me to fix his minibike, told me he used to store drugs under our shed, then i realized he was scouting out our house to possibly rob it.
