On the Kansas City Craigslist is a 1974 Jackpiner. I think it may be a Jim Trickett bike, but his phone number is not listed in the ad, so I guess you'd have to reply to the ad email address.
Rebuilt engine, new gaskets & seals, new rings on OEM piston, frame sandblasted and painted. Petty IT rear fender (white). From the photos it appears it will need a seat cover. $1200.
Also listed on seperate ads are a pair of 1979 Husky 250s, one CR and one OR, $1500 for the pair, and a 72 350 Sherpa T for $625.
