Well, seeing as the replacement dmgrs stat had started to fail open after only a week, I removed it and replaced with the motaquip stat (that was the reason for this thread in the 1st place).
However, this time I drilled a 1.5mm hole, as it was the smallest bit my drill would take.
For what it’s worth, I installed the stat with the bleed hole at the top of the pipe.
Bled the system, as I had done before.
- bled through the bleed screw above the fbh, by raising the tank, until a steady flow thru.
- ran engine at 2500 rpm with cap off until reached 70 deg.
- put cap on and watched temp rise
This time it only went to 87, before dropping to 86, and then rising again, at which point I took it for a spin. (Previously this stat, with no hole drilled went to 96 before dropping)
Now, having only done about 10 miles, stat is no longer operating erratically.
Cycles consistently between 84 -88, rising to 90 under an uphill load.
It will be interesting to see what warm up times are like in the morning.
Who knew you could have so much fun with stats 🤔🤔
