tk.sr500

I have a 1981 SR 500 with 12K miles in decent (probably "Fair") condition that needs work beyond my meager abilities. It was running OK last year until last winter when I neglected it for a few months. Now it only starts occasionally but not for long, so I can't ride it anymore. Cosmetically, there's some minimal rust on the frame, a few dents on the tank. I bought it used recently and never had it looked over by a professional mechanic so I was thinking maybe I should, and while I'm at it, maybe I should bring it back to like new condition. Anyone have any idea how much complete restoration would cost me? With or without new paint / cosmetic stuff (dents on the tank). I know parts for this bike are hard to come by so not sure if that factors in to the restoration price... I really have no idea what a ballpark figure would be, but I'm guessing $1,500? Not looking to keep it all original parts, but want to get it on the street again for daily use - and looking nice if I can afford it... Also can anyone recommend a restoration shop in Northern New Jersey that would work on an old Japanese bike? Thanks a lot in advance. -Tom
