Hi Jake.
Yah sorry. Was saying 40-45 MPH. And kinda guessing at that as speedo
not totally accurate. Not lugging for sure. I can tell by "pitch" of
engine.
Thanks for pointer re: cooling. As one lister pointed out a while
back, keeping the revs up really helps cooling. I do. And not keeping
the "pedal to the metal" for any sustained long duration, is important
too.
In a hurry? No! And I make sure to *try* to let people go past me when
possible. And wow. Can't believe the diff between driving secondary
highways and getting onto #1 here in lower mainland. Yeesh!
Thanks again Jake, and sorry list for such an elementary question.
Searching archives at libraries with dial up modems just takes too
long!
Neil.
