New! Looking at an LT2

[AdamPag]

What's goin on guys, Im looking at a '72 LT2 locally with 1500 miles on it, guy wants $600 for it. There seems to be little to nothing about these bikes as far as specs etc, so I wanted to know what you guys think? It seems to have little to no rust and is complete. He claims the bike was running a year ago but has since been parked so its gonna need a new battery and a carb cleaning. I hate buying non running bikes.

So, what should I expect from this little bike? I have a degree in auto-engineering and have built 2 strokes from the ground up before. Im dying to get on an older enduro they look like a blast.

In addition, im almost 200 lbs... Im definately not gonna be too thrilled with 100cc's so ive learned that the LT2 and LT3 are the "same" as the AT1C AT2 AT3 CT1C CT2 CT3, is there a simple head/carb swap to go with a larger bore? Any help would be appreciated, im def lookin to grab this bike asap before it gets scooped up so lemme know what you think!!
