Good idea? Bad idea?

[CrazyKell]

Looking to seriously learn to tinker this year.

Don't feel like doing it on my own bike but really want to learn about bikes.

Buddy is selling this:

1983 XR200R This bike had the top end completely rebuilt, and did run perfectly, untill the coil started breaking down. It is currently in storage, and would require a new coil, a throttle cable, carb cleaned, and a little TLC. I may do all the work before it sells, in which case the price will go up......$500 obo

Good idea or bad idea to buy this to just pull apart and learn?
