    If anyone wants to DIY the oil pressure gauge:
    1. The oil galley plug - I believe this is M20x1.5 thread. So M20x1.5 w 1/8 NPT in middle to accept fitting. These are available for around $10.
    Exhaust Temp Temperature Sensor Adapter M20x1.5 20mmx1.5 -1/8NPT on fleebay
    2. Marshall makes a nice 1.5" gauge for this. 0-100 psi. $20 on fleebay.
    3. To mount on handle bars you can use clamping 2 piece shaft collars welded together. One bushing 7/8in, one 14mm. These are about $8 each. Look on Mcmaster.com
    4.1/8" NPT 304 Stainless Steel Pipe Thread Weld Bung Full Coupling Coyote Gear SS
    The gauge threads into this and so does the oil line. The 14mm shaft collar also grabs onto this. You can powder coat it or run shrink wrap over it to black it out.
    5. Goodridge Sniper 2 are nice fittings and line so you can custom make your own oil line. I used:
    (2) Goodridge Sniper 2 Npt 90 Degree Male Adapter Black 1/8 SN822-02-18BDY 03-6703
    One threads into the oil galley plug, the other threads into a 1/8 coupling.
    Goodridge Sniper II Brake Line Hose 25' Black 36708 MTB~600~02BK~25
    Sniper 2 Hose Collars Black 2/pk

    Good find on that pre-made oil plug.

    I bought a Kawasaki drain plug and had my neighbor drill and tap it on his lathe. Nice thing about the Kawi plug is that is has a groove that accepts an O-ring. Bad thing is that you have to drill and tap it.

    Kawasaki P/N 92001-1183. Best price I found on it was from NW Vintage Cycle Parts. That was 5 years ago or so. I believe that site is shut down now due to the owner retiring.

    Im pretty sure it will be the correct thread. It's intended use is to replace an oxygen sensor with a pyrometer thermocouple.

    Nice find. The one I ordered set me back almost $30 with shipping. $10 is much better.

    Most O2 sensors I have seen are M18x1.5 I guess there are more sizes.

    It may be for a different exhaust component. I assumed O2 sensor because of the size and it is very common for import turbo tuners to delete one or more O2 sensors and make use of the hole by installing a pyro.

    Greetings from Poland. This is my idea for oil pressure sensor.

    [​IMG]
    Made on lathe and milling machine (only nut). It is very simple and easy to made part. Rest were bought.

    I was questioning this mod but I’m kinda digging it. Does anyone know off hand what the bikes oil psi would read in this install location?

    I prefer the look of the mechanical Marshall gauge but your mod is awesome too. Love the option to go electric and how you hid the pressure transducer. Also, I've noticed when ever I see post from Poland it seems like its always about people fabricating stuff. Seems the Polish are very handy. One of my friends actually has a machine shop and is Polish. Anyways nice job.

    I never did post a pic of my completed setup. I used stainless tubing and swagelok fittings.

    Looks good redneksoldier. I ordered the last of the parts I need to finish mine. I'm going to edit my original post to show the total parts list. I'll post pics after it all comes in.
