gpz1000 motor

I just got a brand new ( full rebuild) gpz1000 motor and i have no idea what its year is and don't know where to look up the serial number. The Number is zxt00ae001394. Can anybody look it up and tell me what year its from also if a 1980 kz650 ltd exhaust would fit on it? If not where can I find a new or good used one?

Thanks for all your help in advance!!

Go to the www.kawasaki.com website as they have info on frames and engines.

If by GPz1000 you mean a ZX1000A, then pretty much nothing from the KZ motors will fit, that's a water cooled motor with the cam chain on the outside of the block instead of in the middle like the KZ's.

I believe what hes talking about is a J model type 81-84 air cooled GPZ1100. The later ones have the biggest valves & best combustion chambers. 81 was injected the rest were carbed with Cv's I think. Early pipes will fit J model engines I have one on mine

With the following engine number??

zxt00ae001394

Here is a 84 GPz1100 engine number.

KZT10BE029301

See the difference?

And all the GPz1100's (81-84 anyway) had fuel injection, none had carbs.

The number you provided is not listed in either Kawasaki.com or Zedder.com suggesting you might have transcribed it incorrectly. Might you have meant KZT00AE001394? In any event, there does appear to be a problem...for example, all early KZ1100B and ZX1100A (AKA GPz1000) motors (1981-1985) started with KZT00BE00XXXXX)...all A model 1100 motor VIN's started with KZT00AE000XXXXX...so technically, you may not even have a GPz motor. The 650 headers will not fit. Anything that will fit a J motor will fit.

Missed the serial number part, just saw the GPZ1100. I thought anyone would know the difference between water & air cooled. My mistake

Before we all get even more confused, I think you had a typo in the following:

ZX1100A (AKA GPz1000)

Pretty sure you meant GPz1100

Interesting, if you search for GPz1000 under marketing names at kawasaki.com, it comes up as 82 KZ1100 B2 (GPz).

Now for the $64,000 question, did Kawasaki actually market the 82 GPz1100 as a GPz1000, or is their website mistaken (again)?

The ZX1000 is listed as first appearing as a 1986 model at kawasaki.com.

A picture of the motor would sure help

Or maybe monsterman21 will stop back by someday and give us some more info.

Lot's of people don't even know what a spark plug is :laugh: :laugh: :laugh:

Edit:

Been searching Google for ZXT00AE and it shows up as the engine number for a ZX10, but everything I found was for areas other than North America.

Example Google translation



.

They were marketed as GPZ 1100's. I bought a GPZ 750 the first year they were out in 82. They only came in red and the 750 had the mini fairing. The first year 1100 had no fairing and was injected. The rest had carbs & the fairng, first the bikini type then the full front one towards the end. Thats the way I remember it and I still have new literature and magazine tests on both. Your opinion may vary. The GPZ 750 was actually in Kawasaki parts literature a KZ 750R1 in 82, that the dual shock model. I still own it.

Sorry, but I beg to differ. All the GPz 1100s 81-84 (KZ1100-B1/B2 and ZX1100-A1/A2 aka Uni-Traks) were injected.

I´d say that their website is mistaken - again!! Firstly, I have never heard of the GPz1100s being marketed as anything but GPz 1100, KZ1100 (B1/B2) or ZX1100 (A1/A2) aka GPz 1100 Uni-Trak. Secondly, over the years I have found sevearal errors on buykawasaki, most notably some serious misinformation regarding KZ 650 alternators (one of which cost me $ 100), but also errors in frame drawings and such - buykawasaki is a good resource but I've come to learn that it's not the gospel, you´ve got to apply your own experience.
