Storage question
New 1200 Iron, tucked away in my heated shop for the winter. Startron fuel stabilizer, batt tender, setting on wood all that stuff, Well...
I don't like the fuel pump just setting there for a couple months, cant be good fer it. Im thinking of turning the key on "run" and let the pump build pressure, I think that would be a "good thing", thinking of maybe doing it once a week, as im working right beside the bike. BUT I got to thinking.....If I do that will it just cycle the pump, or would that also cause the injectors to "pulse"? If so I think that would be a very BAD thing to do, as that would keep washing down the cyl walls. Any tech out there know ?Regards "Big E"

Yep I maybe overthinking.....a little. I was curious if the injectors "pulse" when you just turn the key to run, of if they wait to cycle when the engine is cranking? Just a little info to be handy for a mechanic to know. I have heard, and I hope to know fer sure, that HD fuel pumps and ecms are "marine" grade? If so that's a blessing, as a Auto Tech for many years, I have replaced a few pump and related "stuff", Regards "Big E"

The injectors will not be fired until the ECU gets an input from the CKP (crank position sensor.)
I confirmed this on my 2013 Sportster by logging data on a cold start, no injector pulse until after the battery voltage drop
indicated the engine was cranking.
This is from a 2013 Electrical Service manual:
Without the presence of the CKP signal, the ECM will not allow the ignition and fuel injection operation.
The ECU uses piston compression slow down events of the crankshaft to determine engine phase.
Therefore, the spark plugs must be installed when checking for spark.

THANKS SHANNE, exactly what I was hoping to learn ! I tought that was the answer, but wasn't sure. I don't want the pump just to set idle all winter, I know on automobiles they can "stick", in fact im gonna go out to my shop and cycle mine right now ! Thanks again!

IIRC you will find storage instructions in your owners manual. It doesn't amount to very much, in fact yours is plainly enjoying 5 star treatment, so don't fuss! I've owned bikes for over 50 years and have never done a great deal in the way of 'storage' when not riding any of them for a few months. I haven't had one let me down yet.
Damn - what have I just said.....
