Local place that fabs up all sorts of hydraulic lines for local farm and
heavy-equipment guys also happened to have nickel-copper brake line. Works
great, but I did pay attention to not leaving much of it unsupported. I
figure anything that flexes will eventually fatigue.

OT reacts to slowly. MS uses that signal to control the warmup enrichment
and I don't want to apply the enrichment any longer than it's actually
needed.

And in the winter I struggle to get the oil temp up over 150F, even with
fully functional thermostat and shutters. The first 8 miles in my commute
are all down-hill. Tough to warm it up.

Actually, next time I make changes I plan to fit up some heads that will
take the type-3 CHT sensor. And MS-II already has a built-in cal for it.

It would have seemed more like work if it wasn't so much fun. :D

the modern injectors and TPS.
