Any ideas what would cause condensation on my intake ?
Running a VM18 , case matched 70cc Athena , stuffer crank and Sidebleed .
The high velocity of air and fuel flow cause the temps in the carb/intake to be very low and in cold climates the carb can actually freeze...especially in gasoline airplane engines... I had a Bing carb with a lil'buddy hole that the slide would stick/freeze in weather below 20 deg.F I have since switched carbs but (true story)
I guess she must be breathing good . :-)
Vacuum. Law of gasses.
Must be. My sachs started doing this, which made me curious... computed I'm gettin over 9k rpms.
Also, condensation forms, more readily, on smooth surfaces, like powder-coated intakes
It means you're jetted correctly and your carb & intake are working as they should.
Isn't there a multitude of methods to warm intake gases in autos and trucks. Most mopeds just dont have that design element. I'm sure there must be some exceptions. Perhaps someone can show one.
Cars pipe coolant through the throttle body and often the intake itself.

You don't want to warm it. These small air cooled engines heat sink loosing a bit of power when hot to begin with. My bikes warm up in about a minute or so.
Auto heat risers were just needed when engine was very cold .
I remember spraying/freeing stuck ones on many carbureted cars I had .
Yeah they are there to prevent the throttle from freezing open/closed.
my DT50 pipes coolant through the carb to warm it up. pretty dope.
