Tank for 1981 1100GPz

I am looking for a tank thats in good shape for the bike I just bought because tank that is on bike has large odd dent in right side. Any ideas would be very greatful. Thanks

Become one w/eBay as that is your best chance for scoring one and they are not that common there either. I have a 1982 GPz1100 and have found two tanks on eBay over the past several years...one was a repaint 1982 1100 tank and the other a 1981 GPz1100 tank. Tanks that resemble the 1981 KZ1100B1 tank are: 1982KZ1000R1/ 1983KZ1000R2/ 1984KZ1100R1/ and 1982KZ1100B2. All will fit the mounts on the frame. BUT, beware, the internal gas gauge mounts differently on the 1981 tank (it is a circular 5 bolt mount while the other tanks mentioned above use a oblong 6 bolt mount). So, if you wish to use the existing gas gauge, you must buy a 1981 GPz1100 tank. Expect to pay between US$100 and US$300 for a tank (depending on condition).

Do not forget the fuel return fitting on the right underside of the tank(I have one on my 82 GPZ1100 B2).

Since I have not owned a 1100 are any of the 750 tanks of those years compatable?

Might widen the sucess rate if they were.

I have had two tanks on this bike. The origional was mistakenly expanded via too much air pressure insereted during a leak test.

Strange seeing dents comming out not in.

Good observation, the FI GPz tanks (B models, ZX750E and ZX1100A models) have the relief valve fitting but it may be missing from the ELR tanks (or have a fitting to close it off...don't know, never seen the underside of an R tank). So, if you find an old used KZ1000R tank, have the owner flip it over and look for a threaded fitting on the opposite side of the gas gauge opening. If there ain't one...don't buy the tank:)

No, the 1982 KZ750R1 tank is 2" shorter than the 1981/2 KZ1100B tank and mounts differently on the frame.

Gotcha...
