Hello I am new to the forum and a newer rider.
I purchased a 2004 Suzuki last May (2013) with around 9k miles.
Towards the end of summer, around August I noticed my bike wasn't started so I started hooking it up to a trickle charger and it would last for a few days. At the end of September when it started to get cold I brought the battery in my house to store so the winter cold wouldnt damage the battery.
Yesterday It was nice outside and hooked up my battery to the bike, took a volt meter and since it read 11.7 volts I decided to hook up a battery charger/maintainer that I purchased (Megaboost 4000). This morning The charger told me it was fully charged and so I decided to start it. Well..the bike refused to start after many attempts and a quick recharges with the maintainer. After each attempt I would plug in the maintainer and the it would take about 5 mins to charge back up.
I currently have it hooked up to a trickle charger, in hopes that this might work better than the maintainer.
Can anyone help me with this issue? Do I need a new battery? Or could it be the starter ?
I am sort of new to the motorcycle repairing so any help would be great! :D
What are the symptoms when you try to start the bike? Does the starter motor come on? What is the fuel status? etc.etc.
The engine turns over but doesnt start, lights come on, fuel is about a half a tank.

Fuel in GS500s is deceptive. Was the tank full? How far have you gone to determine only half full?
Try switching it to reserve - too many people to mention have come on here proclaiming ample fuel based on looking in the tank, only to discover, whoopsy, it was low on fuel and needed to be switched to reserve.
...and it does sound like time for a new battery.
I know its about a half a tank based on the miles I usually get per tank. I also have the petcock placed on Reserve when I start it.
I dont think its the battery at all based on the fact the motor turns and the readings from my voltmeter.
Have you checked the spark plugs and verify that you're getting spark.

Just to verify the state of the battery:
Under 12V is a dead battery; fully charged should be around 12.6-12.8 V and charging (bike running) should read 13-15V. What is the voltage you get after charging from the maintainer?
BTW, it is possible that the battery has enough juice to turn the starter motor, but not enough to provide a strong enough spark to get the bike running.
The voltage on the battery is around 12.8 after the maintainer charges the battery.
have you checked/changed the spark plugs? are the plugs wet or dry after trying to start the bike?
I replaced the spark plugs last summer. Im not sure if the are wet or dry though after trying to start the bike. What would this information tell you?

Pull the plugs after a few start attempts. If they are wet, then you know you're getting fuel and there's an issue with spark or possibly bad gas; if they are dry then you have a fuel delivery problem such as clogged/dirty jets etc.
Okay radodrill, I will give this a try tomorrow and post my results.
So I checked the spark plugs before and after an attempt to start, and the plugs looked dry although I did smell gas on them.
Tried starter fluid? If starts, then fuel delivery problem.
If no start, spark problems.
has it been off the road all winter?
Carbs could have iced over??
Heres what you need to do.
1. Hook up your meter and attempt to start reading voltage the entire time. (below 11v bad, replace battery. Above 11v next step)
2. Pull the plug and rest it on the head while cranking. (spark yes or no ) If spark proceed
3. Pull air filter and spray a little starter fluid while throttle is fully open. Than crank it. (if you get some thing tike to look at the fuel and or carbs)
Did you put gas stabilizer in the tank before storing it? If not you are going to need to replace the gas, removing the old gas first.
robfriedenberger-
1. Passed voltage
2. Pass spark plug test
3. Will be doing this step soon...and will post results
And I did put stabilizer in tank before storing it.
Crasm- It has been off the road all winter, stored in garage.
Gas evaporates you may want to set it to pri, than crank on it for a little bit in short burst. Never exceed 10-15 seconds on cranking this can damage the battery/wires/starter....with that being said I doubt that it will happen just need a disclaimer. If you do get it started let it run as long as possible after to work some of the older fuel out of the carb.
Okay I purchased some starter fluid and sprayed it, the bike started no more than a second and then died. I was successful starting it again when I sprayed more starter fluid.
Could it be a fuel filter or a gas filter? Any ideas?
OK. So we've identified it as a fuel problem.
1. Is there gas in the tank? (It can look over half full when you're under a gallon and need to be on reserve).
2. If you open a carb drain screw, does gas pour out?
2. Are the fuel lines connected correctly?
3. Is the tank petcock turned on? (Slot should be vertical)
4. Have you put it on PRIME to fill up the carbs?
5. When on PRIME, if you pulled the line off that goes to the carbs, does gas pour out? (Petcock in ON; pull output hose from frame petcock; run a hose to a cup; put in PRIME; gas should pour out; put back to ON to stop fuel flow)
YES - in-line fuel filters can block the flow of fuel unless it is one specifically for gravity fed motorcycles.

1. There is gas in the tank, and its set on reserve when attempting to start
2. Fuel does come out (I loosened screw on float bowl)
3. All fuel lines are connected
4. Yes I have placed PRIME on for short time, then turned off and attempted to start
5. There are 3 lines that run from the Petcock- 2 going to the tank and 1 going to what looks like the carb. When removing the hose going to the carb, should I turn the fuel switch off underneath the gas tank first? And then turn the petcock to PRIME and then switch the fuel back on?
You need to be on prime for a minute or two to fill up the carbs. For now, put on PRIME to try to start in case there is a vacuum problem.
When disconnecting fuel line between frame petcock and carbs, setting to ON or RES is fine as the vacuum is off (motor not running) so no fuel will flow.
There really are 4 lines to the frame petcock. One small line is the vacuum line which goes to the left carb (89-00), or off of a T from the right carb (2004+). Is it connected?
Did you check the float levels with a clear U tube?
If in PRIME and you connect a hose to a carb drain, do you get continuous flow of gas when you open the carb drain screw? More than what would fill up the carbs? (Like an 8 oz juice glass worth of gas)
2004 the vac line should be connected to the carb.
As stated set it to prime and crank it for a while, if you got nothing its time to get cleaning. It sounds worse than it is.....I don't like to think about it but pulling the tank is the worst part about the whole thing. If you played with carbs before it can be done in an hour or less , if your not used to it take a few hours. The jets are tiny thus can be clogged with a few grains of sand.
Correct - the petcock is connected to the right carb on 2004+. My bad there.
Everything seemed to be connected.
I placed prime on for a few mins and attempted to start it. It only seemed to start for 1 second when I sprayed more starter fluid.
I placed prime on and then connected a hose I purchased from the carb drain/bowl to a container and there was a continuous flow of fuel. So what would be my next step? Seems like fuel is flowing to the carb and no issues before the carb.
From all the information you have gathered. You need to clean the jets most likely old gas clogged the jets, you will need to pull the carb, remove the bowls and soak the jets in carb cleaner. There is a sticky with the carb parts but a service manual is also a good source.

Is this a difficult task- to clean jets? I have never done this before and have no idea how to do this. Should I try to do this myself or take it in?

Naaa its pretty easy. Much like with a chick ... open and poke everything you see.
Cool.
Buddha.

:icon_lol:
Thanks for the laugh!
Your just going to clean the jets, they are tiny (brass colored) passage ways in the carb that the gas fumes flow though. This is an easy job just take your time, if you can see light though the jets when held up to light they are clean if not soak them in carb clearer or use a wire off a a wire brush and poke though it carefully.

Figured out the problem. Had nothing to do with the carb at all.
I brought the motorcycle in the house to warm up for a few hours AND it started! So the true problem is the 17degree weather, not the bike lol.
Thank you for your help.

Could be a lean pilot circuit or that the plugs don't like the cold; with full choke mine starts in the 20-25 F range without much trouble.
.....Some thing is still up.....If it starts when its warm I'd say a can of seafoam is in your near future. I've started my bike in ~10 or lower, it might take a bit of love to start it but it should fire right up.
Run some seafoam in the next few tanks and keep and eye out for any trouble.
Hey Guys.
I am planning on getting my bike ready for spring. I was going to clean out the carb and change the oil, check brake fluid and maybe let my bike run out all the old gas (and replace with new before riding).
Is there anything else I should check or flush?
