Since you mention that you also ride a 4 wheeler, how about offering to take the kid to a local 4 wheeler nature area and do some riding together? You'll get to know each other and he'll have much more respect and appreciation for you. Maybe even help him fix the darn thing so it will idle?

That kid is me at that age and given that a lot of kids nowadays spend hours in front of a video game, I appreciate he's outside and enjoying life away from the TV. If an adult had offered to help me with my new interest, I would have been blown away with appreciation.

Just a thought.
