pitbike motors for the atc 70

[jadleybray]

I would like to swap motors in my 84 atc 70. The motor is tired and I want to pull it, rebuild big bore and such, but want to put another motor in for my son to ride still. So my question, not too concerned with brand, but of all the laydown, bolt in pitbike motors, what are the options with a semiauto tranny? I would like 110-125ish cc, and elect start if that's an option. Not the determining factor as you can always do the pullstart mod.

Get on google and search for a lifan 110.

Lifan makes what you want. Semi-autos, full manuals, etc. From 50 to 125+ cc's direct bolt in to the 70 frame.

A crf50 motor with a 108 stroker kit from trailbikes is also an option.
