I'd have to say the same as Pawlie . Depending on Montana laws (which I know are very much unrestricted compared to mine) you may be able to title it with a bill of sale , just ty to check the VIN for it being stolen before buying it . Here in Wisconsin no title means you will never get a title for it again , the only way is to find the last owner that had the title and have him/her get a replacement title and then sign it over , so basically forget it . The only option is to buy a titled frame from someplace like Ebay as I've done twice and swap everything over. As to price , you never stated which year it was , the '80's (kick start only) version go for $800-$1500 around me and the '90-'95 (electric start) models go for $1800-$2800 depending on condition and miles . If it'd the "E" model I'd grab it if you can re-title with a bill-of-sale and theft check . Heck I have a titled frame here .
