Last night I continued building the test stand, a crude dashboard for the preheat system was made out of aluminum sheet.

The idea is to have a switch wired both to a relay which operates the glow plug and to a timer that opens a propane gas solenoid valve once the plug has had time to heat up properly.

Not very fancy but functional, it is no use overdoing the test stand since I will make a new housing for the preheat when I am installing it in the bike.

I also welded a nut to the jet pipe in which the temperature probe will sit, the idea is to use the bikes oil system and fuel pump but have separate P2 and TOT gauges on the test stand and a separate test stand mounted PWM controller (you can see it below the load cell gauge in the previous pic) for the fuel pump so I won´t have to mess with the bike PWM settings.
