Stacking the Deck

Once mounted, the display looks like it was made for our car.

The unit comes with all of the required sensors.

We made a new dash panel out of .040-inch aluminum.

We're using a Dash-4 stainless line to the 1/8-inch NPT fitting for the oil pressure sensor (on left). You can see the water temperature sensor on the right and the blue wire is the signal from the ECU for RPM.

When we originally installed the ZX10R engine in our LeGrand, we used the stock bike cluster for gauges. This was an inexpensive solution ($250) for keeping tabs on the engine. Unfortunately, the cluster was hard to read at the angles we could mount it, and there was no way to expand it with a brighter shift light or an auxiliary oil pressure warning light.

As we researched new options for gauges and sensors, we came to a conclusion: The lightest, simplest option was to replace the cluster with a Stack display unit. They run in the same price range as many standard gauges with sensors, and we could customize the display to fit our needs perfectly.

The cluster installation started with the removal of the stock unit and its wiring. We then isolated the tach signal from the harness and marked it for later use. Next, we fabricated a new upper dash panel to mount the Stack display, making sure that we could see it well. Now we’re in the process of finding the adapters to mate the included 1/8 NPT oil pressure sensor to our bike engine’s 1/8 BSPT fitting. We’ll also be installing the sensor on a short length of braided hose to keep it from being damaged by the high-frequency vibrations that come with high-rpm use.

You can get the adapters that you need from Pegasus. I went through the same thing mounting a remote sender on one of my cars.

Yep, as well as BAT and our local speedshop. I found one of the adapters at our local hydraulic supply house.

You'll need to log in to post.
