I have not rode my 07 klr in a little over a month now. I tried to start it and it didn't do anything, but the head light came on.I'm hoping that its just the battery, it ran fine great the last time I rode it. I do keep it outside under a cover. I suggestions?

No sound at all? I would still check the voltage on the battery, though there are a few other things it could be as well.

Assuming you had your kickstand up, in neutral, etc. it could be those safety switches or the start button.

I'd start at the battery.

Limited info for diagnosis, but . . . quite possibly, low-voltage battery.

What happens when you turn on the key and press the start button? Any clicks? No indication of starter activation at all? As kyxon mentions above, safety switch matrix may be involved; sometimes, jiggling the clutch lever will convince the clutch safety switch to allow the starter to activate.

A suggestion: Jump the battery with a known hot battery (e.g., automobile battery) and see how it goes.

If the bike starts with a jumper battery, but the on-board battery won't hold a charge, might need to check electrolyte level in the cells and charge it. Finally, if problems persist, a new battery may be in order.

Good luck!

Be careful if you are boosting off a car. Make sure the car is shut off, NOT RUNNING or you WILL fry the voltage regulator on the bike!!

My starter button is tweaky. If I press it straight, it might not work. If I press it slightly on the left side, starts every time. (It's been like that since I owned the bike, about 14,000 miles.) Maybe try pressing it from different angles.

It's a long shot that it's your issue, but it's on the "trivial to test" list.

You all over-looked, the KILL Switch. Must be in Run Position.

Otherwise, 'no click, no nothing', but the headlight is on and Bright!
Yes, it maybe the other safety switches. But the kill switch is the 1st safety.

Good point, pdwestman!

Hardly believable, perhaps, but . . . I considered mentioning the kill switch earlier. Why, then, didn't I? Since to some, the kill switch OBVIOUSLY must be in RUN position, they might think they're being mocked, if the kill switch is mentioned.

That said, you're quite right. In the OFF position, the kill switch grounds the exciter coil voltage and opens the start button line to the starting circuit relay . . . good catch!

I always always check the battery first... Most often it is the cause of electrical woes. Especially on the KLR as it is so prone to boiling off the electrolyte.

Edit: Oops, my bad for not reading all the replies completely! Damocles already covered my battery concerns .
