New 1989 Ninja 750 R on the block.

Well guys i'm new to bikes and the forums so please oh guru's of the kawasaki world show me the light. Well here it is, 1989 Kawasaki 750 R. Friend of a friend owned it. I received it for free, bit of a project I understand. My issue as it stands is I will have to purchase right front section as it has been horribly mauled to death. If I could get some websites you guys might know of where I can find the parts really cheap, I plan to re-use what I can and repaint it all. I'm going to try to salvage the beaten gas tank until I can afford a new one. My mother will be reupholster the seat for me. Just in case, I have yet to buy a manual as right at the moment I am "unemployeed" and will have to wait a few months for job transfer before I can purchase one. Engine does fire up and sounds great. All the electrical works to!


1. I am not sure if I am missing fuel lines or I just need to know how to hook them up.
2. Is there a vaccum system I need to know about?
3. What are the 3 rear ports on the tank for?

-Whats the black box for and what does the hose part of it do/hook to?
-Whats the metal box on left side and what lines go where?


-What are the 3 outlets on the tank for?

-I know I have to fix his "mock connection" for a fuel line
-Whats the black line for?


-More pictures of the bike- http://s200.photobucket.com/albums/a...0Ninja%20750R/

Like I said I am new to all this and some advice or knowledge will help alot!

Are you sure you have a 1989 zx7? The tank you show is not from an 89'. The black lines in the other picture are the vent lines for balancing the carbs. If you look in the mechanical and technical section there is a section for manual link downloads.

08-88 model ZX7R (750-R) I assume correct? I still have yet to find a manual covering 87-90 :( Right now my main issue is I have no one nearby that knows anything about bikes and I have no idea what tubes go where lol I do not have emissions for (CA) So I suppose I don't need the red and blue tubes from the tank plugged in? Do I seal them (ie - rout them into each other?) I am not sure where to go with this or else I wouldent be here lol :D Any help If you guys know would be great!

This looks like a gpx750r, ad list that carbs for sure. If so the engine is almost the same as H models besides the engine head (completely different), how oil pump is arranged and the oil pan. I had a gpx engine and i teard it apart.............and the ignition is different, has two sensors on the crank (slowly it's coming back to me)

It is a GPx750R, totally different than a ZXR750. Your first investment should be a service manual, you may be able to download a free one somewhere, try googling it. Good luck

Yeah i've been shaving the internet for a service manual and no luck on the year I am looking for. My only real issue at the moment is fuel lines :/ Everywhere I look I find fuel line schematics for (CA) Emissions and not normal fuel assembly. So I have tank made for (CA) Emissions and a big without Emissions equipment. My only thought it to route the blue and red stickered tubes into each other (Cross-over) to cancel out the issue with them being in the way. Other issue is the silver switch on the gas tank has 2 valve's (1. main fuel flow, 2. reserve fuel flow) Assuming I am correct on them. The black box confuses me cause it says it's a gas gauge but it has a valve stickong off it. Not sure where this one plugs into or if it's just a breather. Also the carbs have the main in-let for fuel between each set of 2 carbs for main flow from the tank. Then again I have the rubber tube above it thats in a Y section when I fill the lower tube the top one dumps out fuel. Looking for an explaination of why it does that and where it might connect to. :)

-Not exactly sure what you mean Vent lines for balancing the carbs. Does this line hook into the air-box and why does it dump fuel when I overfill the lower fuel line.

The vent hooks to the air box. The vent line connects to the float bowls internally through the carb, it does this to put air into the float bowls to offset the fuel being suck out.
