Thanks to all for the responses about my overheating TR250. I have done the
two easiest things so far:
* open up the drain valve (and poke a skinny screwdriver in there to get
it running freely)
* "reverse flush" the radiator by forcing water through the radiator via
the lower hose until the water ran clean out the top.
Did both steps twice and went out for a drive after each repetition. Each
time the temp gauge dropped from the previous run and it's now down pretty
much where it belongs, so I'm fairly certain I cleaned out a good chunk of
the scale which was clogging the radiator. It gave me a good excuse to putt
around in the car for a bit. ;-)
I may go the rodding route in the future, but will wait until I've put a few
more miles on it and done the flush thing another time or two so I'm
confident I've captured as much crud as I can. I'd hate to clean it out
only to have the radiator clog up again after a few hundred miles with a new
load of "crumbs".
I'm about to make a purchase at TRF. I'll probably pick up a shroud as
well. Thanks also for that suggestion.
