Well, I have a few different bikes. The K is the most modern and the only E start I've ever owned.
Here's three....
1970 Lightning, owned since 1988
1956 Zundapp KS601EL Craigslist find. Disassembled and stored from 64 until 2011, when I adopted it.
Everything was labeled with pencil on marking tape in twist tied baggies. 18 month project.

Solid and dependable 340lb. BLM and Forest Service Road rig. CA licensed and registered.
I'd better check and make sure this all sticks before I continue....
