just curious to know... since if the pressure switch actually works with the RX2 / RX2N, then i would eventually be interested to plug that back in, and put the temp sensor on the oil plug at the bottom.

ps, or maybe the cdi just shuts the bike down if it thinks that there is no pressure to avoid engine failure? in which case, i wonder why the bike would keep working after ive unplugged it...

Ha.... I can explain this....I think


The KOSO has a oil pressure warning light that displays when you turn your key to the "ON' position. This light (oil can shaped) should go off once your bike starts and oil pressure comes up to the required spec. That light is driven from the stock oil pressure sensor although I'm not sure if the signal for it comes directly from the sensor or possibly the CDI.

Now we also know the KOSO has oil and coolant temperature sensors that come with the kit. The gauge reads these sensors to display a temp on the gauge itself. However...the KOSO also has a set point for "over temp" warnings which is displayed using a flashing "WAT" or a flashing "OIL" indicator on the display. The only place I have seen this information is in the setup guide that came with the gauge (see attached).

Anyway so there are 3 sensor's involved (if you kept the stock oil pressure sensor) and 3 different visual displays for them.

1. Oil pressure warning = red oil can displayed on the dash
2. Oil temp warning = "OIL" flashes on display
3. Coolant temp warning = "WAT" flashes on display
