Answer
If the cylinder looks ok, i.e. no deep scratches etc, I would just have it measured to see if it is in spec, if it is, just put a new piston and rings and be sure to have it honed first.  If it is out of spec, you will need to bore it and replate the nikasil coating.  You should not need to resleeve if you are going for a simple rebore.

On the kips, I'm not that familiar with them but I do know they are very difficult to work with, the valves need to be perfectly aligned in tune with the piston.  I suggest getting a service manual, such as clymers, or having a dealer do it.  I did find this link for you which explains the process.

The e, is the year designation for electric start.

Hope this helps.
