I have a 2003 Deuce and my OEM battery went bad, when I would start it the check engine light would come on and then go off after about 30 seconds. Then it left me stranded, while driveing the bike went...


G'day.
Sound very much like a low charge rate(your bike is not recharging the battery).
You need to have the bikes charge rate checked.
Basically-your bike should charge at a rate of 13.4- 14.2volts(DC) when running.
If it's not- the battery will keep going flat.
The test is performed by starting the bike & placing a voltmeter across the battery to measure the output.
It's a relativily quick & easy test to perform that only takes a few seconds-but if the charge rate is low then its caused usually by the regulator or the alternator(stator).
If you have a multimeter-or know someone who does-then the test is pritty easy & you need to do that before you go any further.
If you do it yourself- set the meter to Volts DC at a range higher than 15volts(if the meter is not auto-ranging) run the bike with the volt meter probes touching the Battery(black probe to battery negative-red test probe to battery posative) & observe the voltage reading.
You want 13.5 to 14.2v.
If you can't do it yourself then an auto-electrician or bike shop should be able to do it while you wait for just a few dollars.(only the test though- if the charge rate is low then you have then other issues to solve)

I hope this was of some help
Kind regards Andrew Porrelli

I have a 2003 Yamaha v star 1100. Just put a new battery. Bike will not start after 2 days of riding. Battery sounds like it is drained. It will not start. Someone told me the recharging system is not...


Simplest way to see if your charging system is working is to get your hands on a meter(you should have one to do troubleshooting) and while the bike is running see what the voltage reading is at the battery terminals.Have someome take the bike off idle and run the RPM up and observe the voltage.Typically your charging system should be putting in anything from 12.5 to 14 volts DC.If not your stator isn't up to par.If it seems to be charging check your terminals and your ground strap for good clean connections.If these are good you have a short to ground somewhere in the system and that meter is going to become very handy in tracking it down good luck

if the oil is grey and kind of like a milkshake, that means you have either water or coolant in the oil. if you didn't sink it or ride it through deep water, you possibly could have a blown head gasket or a bad crank seal in your motor allowing coolant to get in the crank. that could lead to the power loss and stalling of the bike. run a compression test first to see if your rings are bad. then a leakdown test to see which seal or gasket is bad.

Need help bike died while riding


everything working perfect. Wednesday night i was riding home from work and got about halfway home bike had a small bog while coming up for a turn onto another street pulled in the clutch and stall. Rolled to a stop and fired the magic button. The motor would turn over and act like it wanted to run (had to give a small amount of throttle) for about 2-3 seconds and then would die. Did this about 5 times and the typical dead or low batter clicking occured. Got the bike home and it has been on the tender for the last 2 days and i just put some time in on the bike and sure enough bike will turn over although kida sputtering and making slight backfire sounds (almost as if timing is off) and will run for about 2-3 seconds and dies. I can do this about 4-5 times and the infamous clicking starts to happen again. Now my bike has never been a cold start bike, i always have to give it a bit of throttle when its cold to keep it running, but once it warms up runs like a champ...or atleast it used to. Its a fairly new battery and has been kept on the tender when the bike is not used for a few days. Now the other thing that bothers me is it seems that oil may be seeping out from where the head and the case meet, but very little. The motor does have a slight coating of oil around the gasket area. I did send the motor to ATK back in late 04 or 05 and had the reliability and upgrade done to it but have only about 500 total miles on it since then, with about 400 of those in the last coulple of months. ,Even with a good bike battery 4-5 tries is about all they have.So forget about the battery and go with basics fuel,compression and spark. Also sounds like you need some mapping help, you should never have to touch the throttle when starting. The will run perfect if they are tuned. Do you know what map is in it? Did ATK also change the ECU to a .atj map?,,,
