    Been experiencing a very unusual headlight flicker on my 1996 Sprint, 40K miles. South Dakota, USA.
    Been a great bike and have had it since new, but last year put in new head light bulbs and now a year later at night I am noticing an intermittent flicker that is not a consistent pattern, or due to bumps and jars in the roadways, or engine RPM changes so I am not sure where to begin to trouble shoot the problem. At idle in garage and varying revs the lights are normal, I can't get it to do it on the stand only riding conditions.
    It's a bit annoying but does not stop me from hitting it hard every chance I get.

    Looking for advise on a possible path of investigation...I hate electrical.

    I would check whilst running the engine & turning the steering to see if that causes any flicker / changes.

    Then I would check all the connections in the headlamp circuit including the earths and removing the bulbs and making sure they fit well and the connections are clean & tight.

    Have you tried swaping out the bulbs for new to rule out a filament fault ?

    Next, check all the connections & wiring in the charging circuit, including all the earth connections

    Thanks for the tips, I will work through them to eliminate each as I go.
    Like I said I hate electrical. I did replace bulbs last summer but maybe one is faulty.

    Gonna start with the new bulbs maybe one is faulty and work my way to power.
    Hate electrical, rather ride, maybe do it on a rainy weekend or this coming winter. In my 40 plus years of riding I have been to the Sturgis Rally two dozen or so years. Now I go to the Black Hills every year in early to mid July for a great 4-5 day weekend get away of riding my favorite roads, twisty's is pure enjoyment on my old girl and we know the roads like the back of my hand even though I live on the other side of the state, 495 miles away. I truly live to ride and ride to live, rally's are ok for people watching but head down and elbows cocked is where the fun is for me.....die hard I guess. Tetons Pass-11400 feet.jpg

    I know what you are saying, as you head through town heading up to Mt Rushmore you get to a point where you can turn onto Highway 16A and head south toward Custer State Park. Highway 16A is know as;
    "Iron Mountain Road".
    17 Miles
    314 curves
    14 switchbacks
    3 tunnels
    and if you run it in reverse from Custer you get the view of
    4 Presidents (Mt Rushmore)
    This is my absolute favorite road and during my long weekend trips I will run this road half a dozen times!!!!!!!
