OIL PRESSURE / TEMPERATURE

Sorry. My ISP is moving the site to a new server and some links haven't migrated yet and react oddly. Don't ask me to explain that, it is what they told me.
Try this one http://www.spookytoms.com/SpookyTom-MTRCCLHT.html and click on "CBX Gauges". If I knew how to imbed a picture in a post I would do it that way.

try tihs, Larry- http://www.spookytoms.com/SpookyTom-CBXGauges.html
the top link didn't work for me so I searched a bit. Nice install Tom.

Oop's

you beat me to it.

Thanks. After all the problems I had recently I figured it couldn't hurt to see what is going on so I can keep an eye on things.

Question:
Should I have the sensor located within the moving oil stream?
I mounted the heat sensor along with the pressure sensor at the old sensor location. I think it should provide an accurate reading. VDO sells a mounting adapter that goes under the oil line fitting but I don't want to fool around with the normal flow by using their oil passage bolt.

Looks nice twinegar, great job. As to your question moving oil stream, the answer is yes or you will be measuring the local temperature only. As to your location the pressure port is connected to the main rear gallery which has flow. The problem would be that the pressure tap is dead headed by the pressure sensor & therefore doesn't see the main flow.

I wouldn't be sticking a temperature bulb in the gallery other than on the ends, as it may impede flow to vital bearings...

I've had sensors installed where you did, in the galley by the crank end caps, in the front of the engine, and the oil drain plug. All the readings were similar. I like your install, I'm thinking about re-locating the guage in my 82 to the same place. Right now it's in the fairing. Pain in the a**.

Thanks. VDO makes a head temp gauge that mounts under the spark plug. They are working some bugs out of it right now and once updated I will probably add it in place of the one I have now. I figure placing it under number 3 or 4 would give a good max temp reading. The sending ring replaces the spark plug compression washer so the plug remains at the same depth. The downside is that the heat range of the gauge is 600. Unfortunately other brands either don't look good or require drilling and tapping a hole in the engine which I won't do. I was looking at a combination VDO gauge out of an old Porche that covered the heat and pressure but the diameter was too big.

Would the gallery plugs be a good location for the heat sensor I am currently using? Are therer any other locations on the engine where a sensor could be mounted without obstructing or looking rediculous? I wonder if some sort of adapter could be mounted in the output cooling line coming from the engine to the cooler.

The gallery end plugs would be a fine position as long as your sensor can take the full pressure...

Don't forget that on a CBX there are two separate oil flows. High pressure/ high flow & lower pressure/ lower flow to the cooler, gearbox & primary chain tensioner....

I just finished the install last night and haven't had a chance to give it a good test but I did go for a 15 minute ride in 75 degree weather and the temp read at 200 by the time I returned home. The pressure read from about 15 at idle to just under 60 at full pressure. The back lights have red lenses that slip over the bulbs that should look good. Any way to get the tach and speedo lights a little brighter?

Up the wattage ( within reason) or convert to 12 vdc LEDS....

Maybe I better just stick with what I have for now. I think it will provide a good enough reading for me to monitor things.

Excellent, thanks for sharing your mods with us....

Is it just me or do others think the lighting is too dim? I wouldn't want it to glow and distract but maybe a 2 or 3 watt increase would do the trick.

I rarely look at my gauges, I can tell by the exhaust note how many RPM I'm pulling. When my radar detector goes off I'm going too fast....

I can barely read the guages on my bikes also.
