Hi there everyone! I just purchased a used vintage speedster and had a question about the low beam function.  when I pull out the lever half way, the dash lights come on and the small bulbs inside the headlight assembly light up... They do not really provide any lighting, sufficient for driving.  When I pull the lever all the way out, the blue "high beam" light on the dash lights up, and there is plenty of light to see for driving at night.

My question is : is this normal operation/function?  Should the "low beam" be providing enough light for night time driving?  If yes, what is the real purpose of the that low beam mode. (perhaps parking/convenience lighting?"

 If there is a string on this already, my apologies.. I'm new

Mark,

The bulbs in the bottom of the headlight assembly are not the low beams, they are parking lights.  It sounds like your high beam/low beam selector switch is set to high beam and that's what you are seeing when you pull the switch all the way out.  Check your high beam/low beam selector switch.  It is typically on the turn signal stalk or may be a foot operated push switch on the floor board.  With the switch pulled all the way out, you should be able to switch between high beam and low beam using this selector switch.

Yes...Those little bulbs that come on are what we used to call parking lights. It's possible that you have a hi/lo beam switch located on the right side of your steering column on the under-edge of the dashboard. Mine is located there by VS. It's just a little button that triggers the relay for the beam selection. Look up under there for it.

Also "Welcome to the Madness" and Congratulations !!

Hope this helps......Bruce

 

Mark, another little documented feature is that you can flash your headlights when the headlight switch is OFF by tapping the hi beam/low beam selector.

Not all VS cars are wired this way, but some are - give it a try.

This is handy for acknowledging all the waves you'll be getting from other drivers as they approach, slow down, and give you a thumbs up. Check out how many motorcyclists dig these cars, too.

Not really jealous about no helmet, I like protecting my noggin with a helmet when I'm riding my Vespa. Our granddaughter Allison likes protecting her head as well when she's riding with me (as seen above).

I love my Vespa and I'm learning to love my Speedster but my Vespa gets 70 mpg and my Speedster seems stuck in the 15 mpg range.

My Speedster is a dilettante requiring constant care and feeding while my Vespa has over 15,000 miles (in 5 years) with only oil changes and tire replacements.

I get thumbs-up while driving/riding both.

And as far as carrying-capacity, they're tied.

Both put a smile on my face...when they're running properly, which means the Vespa wins that race hands-down!

What Ed said.

Will, I think you said you were having backfiring issues, too. That and the low gas mileage are pretty good signs the carbs may not be set up right.

I usually get around 20-22 mpg and 25+ at steady highway speeds. (But who drives these cars at steady highway speeds?)

This article from the archives is a good place to start.

Note that he says a number of other things (like fuel pressure and ignition timing) need to be right first before you even start fiddling with the carbs.

 

Will,

I can't remember if you've got IDFs or Kadrons. If it's Kadrons... there's your problem. Individual runner carbs, nicely set up will deliver 25- 30 mpg even with a wild engine. There are guys with IDAs (48s) with the extra progression port(s) drilled who get that kind of mileage as well.

... but it's rare to find a Kad-guy getting 20 mpg. Most of them are set up pig-rich.
