83 GPZ 1100 oiling ?

reassembling basket case 83 GPZ 1100 and am at the stage where i am cranking the engine to build oil pressure. all the spark plugs are out and grounded, the oil cooler lines are off and in a pan. cranking at a pretty good speed, no oil is coming out of either line. i expected it to appear after a bit, but no. the oil pump seems to work fine on the bench, the bypass is closed, and the gear rotates in place. i made up an oil pressure gage to try next, but don't expect it to give me much. any thoughts?

Not sure what's up, I ass-u-me that you have oil in it and the pump is / was primed. These motors don't run much oil pressure to begin with (3-4 psi at idle), but sometimes it helps to hook everything up as IF it were to actually run? Just a guess?

The main reason your oil light in your car stays out that scarry moment after an oil and filter change, and it is started for the first time, is because it is purging the air out of the lube system

new 10-30 oil (for initial startup only), pump had oil in it and pumped on bench. i'm looking for oil to come out of whichever cooler hose is the feed, but not getting anything.
i ASS-U-ME thats where it goes when it leaves the pump but after cranking, i can blow freely thru the lines????.
does anybody know which line is the feed (output to cooler)?

How much motor oil do you fill in????
If the oil level is below the oil pump intake nothing will come out the lines.

I the oil goes through the filter, then up to the pressure switch for the oil light, reference the service info that Scirocco posted. I am not sure where the oil cooler comes into play here, and I did not see it in the diagram. My bike doesn't have one, although It would probably be a good thing to have.

There are also a few o-rings involved with the oil pan and pump, if I'm not mistaken. But then again, this is just a big guessing game, with no background info on you or your "basket case".

If a pump works, and there is a liquid present, it will pump the fluid. Perhaps eliminate the oil cooler from the equation, and see if the oil light goes out?

The oil pressure switch is right next to the vice grip in the pic, and this is where the oil comes up from the oil filter and is routed into the oil galley that lubes the engine.



Just FYI, the Kaw 1000/1100 engines oil capacity is ~ 3.7L .

thanks for the pics and info. the problem i have is: a gpz has a different system. no oil pressure switch, and a couple of adapters to connect the oil lines to the cooler. the po had new oil hoses made, so i don't know the i.d. of the originals. based on the oil flow diagrams such as the one above, it appears the oil goes directly up to the port where the kz pressure switch sits, then to the transverse galley. i am guessing the cooler lines come off where the switch is mounted and should eventually fill with oil. is there a check valve that keeps it from flowing back to the filter /pump / pan? maybe it starts to fill the line and runs back down. i will pull the fitting at the transverse port and see if it come out there.
does one of the supplement manuals address the gpz?

The GPZ service manual page 77 tells of the oil cooler hoses and routing. You did install the o-rings in the oil pan and pump, I ass-u-me. lol

Pictures are worth a thousand words. literally.

wow! thanks for the pdf. will prob answer a lot of future questions.
...and the o-rings are in place.

No problem Ned. There is a lot of good info and links on this site. I save all of my old kaw pics and manuals into my kz1000#2 folder on my notebook. (This is my second Kz1000 I bought in the last few years). They are always non-running, and always a project. It keeps me out of the bars and court rooms. (kidding!) lol

Just save it, then skim through it offline, take mental notes on everything you can. You can look things up again, as needed. I usually print the pages for faster reference in my workshop. I also take notes and write part numbers on the paper with an antiquated and unheard of utensil called a "pencil".

I can't always help as much as I'd like, depending upon if I have a work project going or not. (contractor here) I am a mere newby minion compared to the REAL long time knowledgeable members here. They give some good and solid advice on anything and everything.

My 81Kz1000K1 after I put in rings last fall.

The German and the English GPZ 1100 service manual page 77 tells the same of the oil cooler hoses and routing. But no pic of the engine lubricating system with oil cooler in both manuals.

well, i gave up trying to prime the oil, put the cooler lines on, replaced the frozen fuel pump, put in the plugs, and fired it up. it lit up and in about 10-15 seconds (seemed like an hour), the gage i rigged on the right side oil galley port popped up to about 3 psi,; 5 when bring up off idle. so i guess it's hard to crank to pre-oil.
idle kinda sucks, but i'm amazed the injectors work as well as they do since i didn't clean them. anybody have a favorite additive for the fuel?
also noticed the tach randomly hiccups a bit coinciding with an engine miss. i suppose it will take a while to work out the bugs.
thanks to all who helped this old guy get the old bike back to life.

Check the injector boots for leaks . My turbo would  hiccup like that when I had a leak in the boot. Sometimes you could see a puff of some come out of the boot when it did it .
There's a guy in florida that we send our injectors to for cleaning and flo check . Its not that much to get them done . Little over a hundred for all four . He sends the out somewhere . T hey come back just like new
