Headlight toggle

Given the frequency of difficult starts some of us have with our bikes...has anyone put a toggle switch on the headlight to turn it off during starts? it always bothered me that the headlight came on while trying to start the bike, robbing power from the starting process. would that even make much difference?

Actually, when you turn the switch to start the bike, the headlight is off until the motor makes a certain amount of revolutions (not sure how many) or is running.
If your headlight is coming on when you put the key in the on position, then your PO did something to bypass that circuit.

i thought something i was typing didn't quite sound right...im basing this off memory as im not in the same state as my bike right now. maybe what im thinking of is since often times it takes several tries of cranking to start the bike, after the first try, the light is then on, robbing power from the subsequent cranks

Hmm, I see you have the Big Crank and Iridium plugs like me but, mine turns over immediately; even if its sat for 3 weeks. Plus, once I'm riding and for the most part the RPMs are above 2,000, she's charging.

Are you using a full choke on start up? Perhaps something else is going on and other will chime in.

You have a switch already right in front of you. just turn the key to "off" then back to "on" before each starting attempt and the headlight will not stay on.

If it takes more than 2-3 tries to start your bike you have some other issue to deal with , the headlight not being the cause.

Doesn't the headlight deactivate when starting? I mean after it's been cranked over but not started? IIRC, it should during the time the starter is running.

Yes , but what sometimes happens is the bike does not start, but has "turned over" enough for the lights to go on. They do not go out unless you turn the key off...which means that if you have to hit the starter several times to start the bike, it is possible for the lights to come on and stay on while you are trying to start the bike.

I am unsure what critera needs to be met for the lights to go on, but it is not a "running motor". It may appear that the headlight goes out when attempting multiple stabs at the starter button to get the bike going, but I think it is just the light dimming do to starter robbing the power from the lights.
Perhaps someone would like to drain their carbs , turn off the fuel and see what happens when the bike turns over but won't (can't) start after multiple tries? (I suggest having someone in front of the bike to examine the headlight condition)

drguitarum2005, I put a toggle switch on mine and like it, especially in the winter months when I just crank the bike up and let it run a bit to warm & stir up the oil, burn out the older gas in the carbs, and with the light out the battery gets a quicker recovery charge...

I think most of the people on this sight would say that after you install the big crank and with the iridium plugs you should not have any starting problems anymore. Hot or cold, and then if you do like the others said you have other problems. Hope you get back to your bike soon, that is if you will be in an area with good riding weather.
