I picked up this 74 TX650A off craigslist in April for $350. There wasnt much to it, as the guy started to cafe racer it out, so there was no tank, handle bars, seat, basically motor and wheels and a bunch of miscellaneous parts in boxes. Only thing i could check is the motor turned over, luckily, cause its been sitting out in the yard prob a good couple years.
The build went pretty smooth, i fabbed the hardtail, seat, pipes and handle bars. Picked up an old yamaha tank from the Boise Vintage, hand controls off a xs750.
Will most likely will pick up a nicer rear fender and new tank, from TCBros and the current upgrade is a Pemco ignition, my timing keeps getting tweaked for some reason.
