Zephyr 750 Exhaust

 by kaptainkwak
A friend of mine fitted a Vance and Hines system to her 750 Zephyr bought off ebay for £85. We needed a new set of collets but when i contacted them i was told they didnt make an exhaust for the 750. mmmmm Interesting. If i remember correctly the system was off the GPZ1100. We made collets from the adaptor sleeves used when fitting new silencers. Simple and cheap

Fuel pump for GPz1100 1985

 by johnboy1
hi all.
i have a GPZ1100 1985 (Fuel Injection Model). the fuel pump has given up on me and i can't find a second hand one anywhere.
i read an article which i found on the internet from someone who had the same problem.
he used a Walbro GSL392 fuel pump, please see link:

fuel pumps online

he does not go on to say wether this worked or not.

does anyone have any advice on this or any other fuel pump that will work.

many thanks.

The bike is an 82 kz1000J and it has a 84 GPZ1100 motor
Rear tail light and turn signals mount bracket 23062-1032

Headlight Inner and Outer Ring ( The headlamp bucket came through unscathed)

Pulsing coil cover for 83-84 GPZ1100 motor- 56018-1407

Odometer- This is the 3 pin for both the black and white connectors. I had what I thought was an extra and it looks exactly the same except the white connector is a six pin. I don't know if it could be adapted but I rather have the correct part and not experiment in possible futility.

Rear turn signals both left and right

Plastic fuel tank vent cover- 14024-1434 This is the plastic fuel vent cover that snaps on to the sender under the gas tank (Yup he dented the tank pretty good but fortunately repairable

Interesting stuff...that is not mentioned in the 1982-88 Kawasaki Recognition Manual for that model. That white is also not mentioned in the manual. Seems that the recognition manual has a few gaps in information. For the 1982 KZ1100B2, (aka GPz1100) the manual mentions Firecracker Red as the only color available, yet the Euro edition also came in Sonic Metallic Gold (note my Avatar...that is the only photo I have ever seen of it). Supposedly Sonic Metallic Gold was also available for the smaller GPz's -- KZ750R1 and the KZ550H1. Never seen a GPz750 in Gold but I have met a fellow from Canada who had a 1982 GPz550 in Gold.

So, did all the Euro J models have what we in North America call the GPz-style tank? That GPz-style tank didn't appear in NA until the J3 model (and of course, on the GPz1100's).
My one was a J1 got it new in May 1981 they came down with a GPz-style tank...
As it happens a guy i know has just imported one from Spain and it has the same GPz-style tank so it would seem all euro J models are the same...

Kawasaki names

 by gazzr11
Gpz900R was known as the ZX900A1 onwards, depending on the model year. It's the model designation Kawasaki gave it. Another example is the GPz1100 unitrak, known as the ZX1100A1/2/3, again dependant on the model year.
It's nothing to be concerned about, enjoy the bike!! :D

zrx question

 by Kawasakifreak
Modok1313 - you asked for more info.
The ZRX has nearly tempted me but I went for the GPZ1100S in the end for the wind protection for touring.
Anyway - the ZRX uses a detuned engine from the ZZR1100/1200 which was the fastest poduction bike in the world from 1990 to 1996.
The ZRX deliberately copies styling from the Kawasaki Z1/Z900/Z1000/Z1R of the 1970's & early 1980's which is no bad thing. Many consider it the best-looking retro street bike which has plenty of real world performance to match.
The later 1200 version has more mid-range torque for easier acceleration.
Keep the bike clean - as with my GPZ - the finish is ok but can fade in colder climates if neglected.
I could still be tempted one day !

It seems Mikuni BS34 carbs fit.
Have a look here, I've read other stuff on the forum re EFI to carb conversions. I've not had time to do a thorough trawl...
