My beautiful wife and I headed for the coast yesterday since Atascadero was slated to hit 105 degrees (it did). 

We left around 10 am after I returned with White Cloud from a "cars & coffee" in Paso. 

We drove to Cayucos on Old Creek Road, our favorite Vespa road. From there we went to Cambria, stopping at our friend Aaron's restaurant (Linn's) for lunch (Aaron loved our car).

We headed home over Santa Rosa Creek Road, a road we often drove in Kathy's '58 cabriolet (43 years ago).

We're still getting used to all the thumbs-up, smiles, horn-toots and comments (and I thought riding a Vespa was the best way to elicit those).

Here's Kath in Cayucos, in White Cloud. They both did great!image

Will....With a good A/F ratio meter and some borrowed jet drills I settled for 48 on my idle jets. I have a 2110.  The A/F ratio is 13.8 on an average and my mpg is 27 to 30. 185-15 tires, 4.12 R&P. .82 4th gear.  I just couldn't handle the rich black smoke with the carbs on right out of the box from CB Perf. I recall it took me about 65 miles of road testing to get the combo I was happy with.  The oil temp gauge you have is like mine and it's running in that same margin as well, I do have a Dakota digital gauge as a de-liar unit though. Come to think of it, now I can't remember what jets I have for mains and A/Cs, the emuls are still F-11...........Bruce

Proper air/fuel mixture plays a large part in cooling, and you'll find that when buying carbs (even when requesting them being jetted for your engine) they will always be a little rich. Even a custom built engine will be just on the rich side if the builder doesn't know the customer well and/or the engine is being shipped to a different locale. It's better to err a little on the rich side, as it won't hurt to run that way for a little while while you get the jetting sorted out (as you're creeping up on the optimal tune). If you were to just get in and and run it that way (without noticing it's a little rich, as some guys will) it's not a major concern, other than mileage being not quite what it should be, it's not making all the power it should be and the slightly accelerated wear on the cylinder walls and rings. It will even help a new engine run that little bit cooler during break-in.

Starting an engine up and the mixture being lean, otoh, can be disastrous, especially with a new engine that's just been started and running a little hot already could be cooked in short order by a lean mix. Even adding dual carbs that are jetted too lean to a well broken in engine will cause it to run hotter,  and (in either case) I'm sure CB Perf. (or any other carb supplier or engine builder) isn't interested in replacing engines on a regular basis.

Pretty much agree with you Al.  Here's an interesting thing I found though. When I was doing all my 65 miles of road testing with my A/F gauge connected I got pretty familiar with all the gauges and noticed that the Cyl head temps went down as I got to a leaner mixture when I was at "freeway" speeds. I also noticed that they went up with slight initial timing changes either way.

Susan and I are taking Rhonda out tonight at about 7pm. Just to do a cruise West on Hunting drive. Probably get some TUMS.......(Thumbs up per Miles).......Bruce
