Carb icing and injection - stupid question?

    The SV is fuel injected and therefore has no carbs.

    Wahey! I say, no carb icing.

    Is there some parallel complaint which bikes with FI can suffer from
    instead? After all, cold moist air is still getting in there.

    Not really - fuel injection doesn't have the whole complex mess of
    jets, neddles, emulsion tubes etc etc. Just a squirty thing.

    Thank you. I thought not, but then hadn't heard either way. As I shall
    be riding it right through this winter, I thought I'd like to know.

    Cold, moist air is actually A Good Thing as far as engine performance
    goes, but those Luddites with carbs just keep complaining about it.

    I would guess that as FI doesn't need a venturi then there's less of a
    pressure drop and hence less of a temperature drop in the throttle
    body as a result.

    In addition, I believe that the injector solenoid will warm things up
    a tiny bit. I think I read somewhere about the solenoids in at least
    one type of injector being cooled by the fuel flow, but ICBW.

    Techno-bullshit ends.

    True, the best MPG I had from my 1970 SIIa FFR LWB Land Rover was on a
    cold, damp night. Almost foggy but not quite. It's the only explanation
    I have for 24 mpg, Westbury - Leicester along the Fosse Way.

    Are you sure you didn't get a tow? Or did you coast down hills with the
    engine switched off?

    No.

    Lorry tyres, Webber carb, FWH, electric fan (ex some BMW or other) and
    very well maintained.
