1982 GPZ 750 project

Well I am finally getting to my GPZ750 after 3 years of it sitting around, I bought the bike for 600 and is in pieces, a 810 kit was installed incorrectly and broke the rings, so after a few years of me gathering the parts its time to get this thing going back to stock, minus the exhaust and air box. So a few questions i have are, is this bike worth anything? I dont want to do a Lawson bike and im not a fan of the red. The bike needs to be repainted anyway and i had found the 1983 1000r euro in white and i love it, i know its not original for the purist out there. i still need to find a set of rims, the front has a slight bend and it has a gpz turbo rear wheel that i dont want. Pics to come tomorrow

I also have a 1982 GPz750...on the proverbial backburner waiting for me to get off my butt and finish it. Something always comes up. As for value...they made many of the 1982 version...perhaps as many as 15,000 units. A surprising number are survivors but they are not as desirable as their earlier, bigger Z cousins. I have seen several sell in the US$3000 range but they were exceptional concours quality bikes and 100% stock...most top out in the US$1000-$2000 range. So, if you are looking to recoup any investment, and you restore/refurb the bike...it isn't going to happen. I already am into the bike for US$1600 (including purchase price) and it isn't completed...but mine is a labor of love and I have no expectations of getting my money back.

As to value, it is not a collector's item, and with your goals it will never be one. OTOH, it is unique in several ways. It is the first GPz750. It is the only GPz750 with dual shocks. It is the first GPz750 engine, which, as we know, is based on the KZ750. It is the only GPz750 with the fork mounted mini-fairing.
IMHO, its value is only what you feel it is. They are fun bikes. They are much lighter than the GS750s which were based on the KZ750 engine. They handle pretty well. I an not sure how they would be on the highway. I owned a 81 KZ750 and it was a handful on the highway, probably because it had no fairing at all. OTOH, my 83 GPz750 is fine on the highway with its frame-mounted fairing.

You will never get what you put into it. As Mcdroid stated, it is a labor of love and you should consider it a hobby, nothing more.
Best of luck.
