I had the same probs with the 1380. on idle the tempo would shoot up. And that was with a 4core alloy rad, oil cooler and elcetric fan. I went through all the usual stuff and changed my guage sender, voltage stabiliser, then changed to mechanical guage, all showed same temp rises.
I made sure it wasn't an air lock in water sustem. It wasn't.
I tried all sorts of fueling mixtures and timing adjustments. changed themostat, then tried with out one, all to no avail.
I then went to rolling road and got fueling and timing properly sorted and it was immediately apparent that it the temp problems were sorted. So I'd recommend that.

every other engine i've built has used the hi-cap water pump, but for various reasons I couldn't source one this time round, so a standard one had to do.
Its booked onto Baldwins rollers on the 30th, so I'll see how it goes up until then.
Being concerned about 80 deg C is silly I know, I'm going to start cheap and replace the temperature sender before I do much else I reckon.
Thanks for all the replies so far, given me lots of ideas...
