Hi Everyone,

I'm having an issue with my '00 GSXR600 (bought used a few weeks ago) and figured since I will not really have any time to properly address it this week I would make a post and see what you folks had to say.

The other night I rode the bike to work and it sat overnight in about 35 degree temps. I started it in the morning and it started right up, but I let the choke out too quick and it stalled......caput. No power. I jumped it and it started right up no problemo.

Then yesterday I rode around a bit (temps somewhere around freezing) and ended up at a friend's house for about 10 minutes, during which time the bike sat idling in his driveway. When I left his house I stalled at a stop sign and again, caput. No power. Had my friend come by and jump me and she started right up and I got home.

I hooked the battery up to a trickle charger overnight and rode the bike to work again today. It sat all day somewhere around 40 degrees and started right up when I wanted to come home. BUT...I noticed that both the headlight and tachometer gague would be dim at idle and brighten considerably when I get on the throttle and bring the RPMs up a bit.

I have noticed that the bike idles at only about 800 RPMs and want to take care of that and adjust it to about 1200 ASAP. My question is...can such a low idle rate drain the battery if the high beam is on and it has been sitting in the cold? Or, do I simply have a battery/electrical/power issue? Are the dim lights a symptom of battery issues or is that common for all bikes?

I am no wrench and will most likely need to find a good mechanic for my bike, but I will not have time at all this week and next due to serious amounts of work. I just thought maybe this could get kicked around on the forum a bit and might help shed some light on the issue for me.

Thanks,
Joe

That's what's supposed to happen. When your generator is at idle it isn't making much power. When you rev it, it makes much more. That says your problem is probably the battery. Either that or you have an intermittent connection problem. Check all terminals for corrosion and tightness. If you have a Batteries Plus nearby, they'll check the battery for free.

Do you mean jump the bike off a car battery? Just don't have the car running.

Thanks for the replies. I did jump the bike with the car off after asking a friend of mine who is mechanically inclined if it was safe to jum,p a bike from a car at all.

Hopefully I will get a chance to pick up a battery this week and see if that is the problem. All terminal connections are spotless and tight, so I hope it's just the battery dying.

Thanks again,
Joe

Wait a second: Whats wrong with jumping off a car, eh?
Car batteries and alternators generate alot more power than a bike battery, and can fry the electronics of your bike. If you must jump-start the bike from a car, make sure that the car is not running, so that you are jumping just from the battery and don't have additional power coming from the car's alternator.

As an example, my bike has a 12V, 12Ah battery, and my car has a 12V, 55Ah battery. That's 4 times the power, which can overload the electronics of my bike if I try to jump-start it.

Not quite, inspiron. The 12 volts supplies the same electrical pressure regardless of the amp-hour rating, which indicates capacity, not power. It's the overvoltage that a car's alternator produces that fries things. They often put out 14+ volts, which increases the current flow. As you know, a car's battery is capable of huge current flow, but it's only an issue if the voltage is high or a short occurs (sparky).
