First - newb to the site. Glad I found it. Had been part of the Yahoo Groups sites, but apparently they've gone down.

I've owned a 1981 baby blue C70 Passport for nearly 25 years. It currently has around 2,500 miles. I’m on the cusp of retirement, and I want my first post retirement project to be an engine swap for this bike.

I remember going to DrATV many years ago and seeing lists of items to purchase for an engine swap. I'd like to do a 125cc semi-automatic, with electric start. Now I only see a 110cc list on DrATV.

I'd like suggestions on engines,(item numbers, where to purchase etc) to do the following:
  • 125cc (would consider 110cc or 140cc)
  • Semi Auto 4-spd
  • Electric start
  • 12v or could stay on 6v.
In looking at some engines (like the 110cc on DrATV) that have a bottom mount electric starter. Does the location matter? Thanks!!
