When fitting a Yamaha R1 into a car, you'll obviously want to know what the oil pressure is doing, it's also a good idea to keep an eye on the temperature. But where do you get this on the R1? There are a few common solutions here -

• Tap the main oil/water cooler bolt
• Tap into an oil galley core plug on the engine (most obvious one is under the timing cover). The good point about this is it's direct into the oil flow, the bad point is that a lot people are afraid to drill direct into an engine block!
• Use a sandwich plate between the oil/water cooler and the engine. Again, good because it's in the direct oil flow, bad because some cars have very little clearance between the oil/water cooler and chassis rail.

The entire process will take an afternoon with parts costing less than £40.00.

Drain the oil from the engine and remove the main bolt holding on the oil/water cooler. The oil/water cooler will be loose and will drip, so be sure to catch the spill.

With the retaining bolt out, tap a 1/8 npt thread into the oil/water cooler bolt. This will allow you to place a capilary tube to pick up the necessary readings.

With the capilary in place, you can terminate it with the pressure sender. Another alternative here is to take a 'T' off to get a reading for oil temperature. While this is a nice and simple solution, the temperature reading may not be 100% accurate as it is not in the oil flow (but for most purposes it would be sufficient - if time allows the preferred solution is to tap into the sump and get a direct reading).
