    Biggest effect?  Canceled my moto trip to Spain last year, and my trip to the Himalaya's this summer is hanging by a thread.

    Lucky that I'm a engineer by profession and have been able to work from home no problem.  Personally, I'm very strict on public interactions and so far, so good.   Wife is eligible and scheduled for vaccine at the end of the month.  I'll have to wait a bit.

    If you are helicoil-ing a block, you need a bottoming tap, not a tapered tap.  The tapering tap can be helpful to cleanly cut the 1st couple of threads at the top of the hole, then finish in with the bottoming tap.

    In-Tank Fuel Pump Electrical Question

    in Technical Topics

    Posted

    None of the in tank electronics "spark".  If they do, that's badness.  And yes, the pump motor is brushless.

    Edit - I don't think the pump is brushless in early 2000's.  The brushless motors are becoming more common. I know this because my company build the controller chips used for these motors. (A good business for us!).

    It's the concentration of the fuel vapor that prevents explosions.

    From Google -

    "The reason electric, tank- mounted fuel pumps do not cause explosions is that the concentration of fuel vapors is too high to allow an explosive mixture. The volatile (which in this context refers to a tendency to evaporate) nature of gasoline causes fuel vapors to take up any empty space as the fuel tank is emptied. Even if you completely empty a tank, open its access ports, and allow it to sit open, the concentration of vapors INSIDE the tank will still be too high to explode. Now, OUTSIDE the tank is a different story, and for this reason, one must use caution when performing any sort of repair or maintenance to a fuel tank, regardless of the type of pump used on the vehicle."

    Fuel Quick disconnect option?

    The Beemerboneyard ones are metal replacements for the shitty plastic ones used on BMW bikes.  The plastic ones have a nasty habit of cracking and spewing high pressure fuel all over the engine.  Very common BMW problem.  Had to do a rather long ride home one time hoping no one threw a cigarette butt at me.

    Scura on the Salt River Canyon Loop

    in Travel & dealers

    Posted

    Took the Scura out for a ride around what Zonies call the Salt River Canyon (SRC) Loop.  Ultimate social distancing. Just over 300 miles worth.
    From my home in Mesa, AZ to Globe, across the Salt River Canyon, Show Low, along the rim to Payson and back down into the desert and home.  
    Lots of traffic in the Payson area. In these days of C19, lots of folks going camping for weekend fun.
    Caught a few monsoon sprinkles along the rim.
    I would say that the Guzzi purred like a kitten, but that big twin sound is much more like a flatulent Italian grandpa who ate too much spicy Italian sausage.
