Oil guage install.

I got one of those oil gauges with my bike,it needs the fitting which i figured i can grab at the hardware store. My question is do i just take that bolt out of the engine and screw the fitting in then the gauge?

it has to go in the main oil gallery just below the cylinder block on the right hand side what kind of oil pressure does your gauge read. the oil pressure on these engines are very low less then 10 psi at higher rpm's because of the roller bearing crankshaft.

What year/model of bike? The older bigger 4's with the roller bearing cranks(Z1's,Kz900's,Kz1000's and Kz1100/GPz1100's) ran between 2.8 and 3 PSI so a standard oil pressure gauge would not read correctly.

It's just a 30psi white faced gauge that came in the box with the bike. I know where it goes,just not sure how.

Like everyone else said, we have to know the year/model of your bike.

If it's a Z1/KZ900/1000/1100, it has a plug on the right side of the crankcase, at about the 11 o'clock position from the points cover. Your oil gauge can be plumbed in there. It's a metric thread, but I discovered that a 1/4" NPT pipe bushing will screw into the threads. I used red loctite to seal it instead of teflon or thread sealant, because I didn't want it to vibrate out.

If you have an oil cooler that uses connections at the oil block underneath the carbs, it can also be Tee'd off of your oil cooler line.

I used a 30psi plain industrial gauge with a bottom pipe thread connection. The oil pressure on mine can approach 20psi when cold and revving the engine, so I didn't want to use a gauge with a lower scale than that.

It's a 1977 kz 1000,sorry forgot to put that again! I would like to mount it right where the hole is,at the 11` oclock position above the points cover. So can i go to a hardware store for the fitting?

might have better luck at auto parts store

I'll put that on my list of stuff to do to the bike tomorrow.

a 1/4" NPT pipe thread

Should be able to get anywhere they sell pipe.

It should go into a T fitting installed where the oil pressure sending unit is formerly screwed into the engine. That is the main pressure point off the pump. Then screw the sender into the other side of the T.
