To get around the 34 year old promise I was forced to make to Santa about being a good boy all year to get gifts I decided to buy my own Christmas present this year.
I got an Autometer exhaust temp meter! With all the trouble I have had trying to measure a correct exhaust temperature I decided (after some poking from John) to buy a calibrated set of quality stuff instead of trying to find a gauge and thermocouple that works together.
Here the Autometer gauge is fitted to the dashboard, very nice with an analogue needle gauge instead of some digital numbers that never stays the same for a quarter of a second.
With that done I continued on the water injection, I connected a P2 line to the water regulator so the water pressure will increase when P2 pressure rises. Then I removed the regulator lid and made a 1/8"NPT threaded hole in it for a pressure switch.
The pressure switch is adjustable just like a Hobbs (but at 1/10 of the cost) and will be used to activate the water injection when the P2 pressure gets over 2 bar or so. I will have enough to think about while driving so I want the water injection to be fully automatic.
Here I have fitted everything to the bike again, all that is left to do is to wire the pump up and test flow the spray nozzle to find a good setting.
Cheers!
