Charging battery

I know I've seen this answered but I'm unable to find it..

Should I charge my battery at 6 or 12 volts? I've been trickle charging at 6 volt setting. Today I went to start it and not enough juice to start.. There is an indicator on the charger that lights up for either "charging" or "charged", the "charged" one is lit :thumbsup:

it's a 12v battery!


The owner's manual says:

"The standard charging rate is 0.7A x 5 to 10 hours."

Then it says:


Exceeding the standard charging rate for the battery can shorten it's life.

Never exceed the standard charging rate."

So, looks like 12 volts at 0.7 amps for 5 to 10 hours (according to Suzuki).


I use a battery tender and it keeps it charged all the time. I just unhook and ride.


12 volt setting. Don't worry about charge rate. You can be sure the DRZ charging system charges higher than .7 amp. Just don't boost it with a 30 amp booster charger for a car battery.

Ok thanks! You think charging it at 6volt may have ruined it? When I set it on 12volt now, after a couple minutes the "problem" light comes on. It is a battery tender "type" charger that turns off when fully charged.

My manual says not to exceed 3 amps with a 12 volt charger.

Recharging times: 0.7 A for 5 to 10 hours or 3A for one hour.

However the smart chargers are the best bet so you don't cook the battery.

Make sure you dont have the polarity wrong. + to + , - to - it's easy to hook to the battery wrong. Set on 6v it likely never "called" for the tender to kick in.

Spring is a good time for small battery manufacturers,they got some of my money this year.

I use a battery tender and it keeps it charged all the time. I just unhook and ride.


Me too. Nee nee neee neee vroom.

If the battery has not been maintained above 6 volts for a long time (like all winter) it is probably a gonner. Have a shop charge it with a real charger to see if it can be "kick-started" back to life. I have no idea what the lights on your tender mean. Get a volt meter and use that.

I charge mine once per month for 12 hours, at 12 volts and 2 amps, while I have it in the basement for winter storage. I've been doing this for years, with dozens of bikes and jetskis. I've never had to replace a battery.

Free tip...

Never store your battery on a concrete floor. Always store it on a wooden shelf or bench.

Ok, I may have ruined it by leaving it at 6volt during the winter.. Good thing I have a kick starter!

      I'd like to turn my UK 2004 DRZ400S back to stock airbox (snorkel) and jets, needle shim position etc
      When I bought it the PO had fitted a Sigma6 kit and done the 3x3 mod but is doesn't have a tapered needle like the JD and other kits. Took me ages to get it running right, however it still runs rich and I'm fed up of arsing around with it. 
      So I've bought a standard airbox without 3x3 hole, stock exhaust.
      Q1 The Suzuki manual says this Mukuni BSR36 (29FA) carb should have a 142.5 Main Jet but the Clymer manual say its a 135.  In UK everything's from sea level to 1000m. I'm in Sheffield so nothing gets above 500m even in the Peaks (Hills). Any UK owners or anyone else know what the correct jet should be?
      Q2 Says the original needle is a '5DH36-2nd'. The needle has 5 notches on it. Currently set at 2 clip from bottom. The Suzuki reference says needle is 5DH36-2nd, Does the 2nd bit mean 2nd from top or bottom?
      Q3 - Does anyone have a detailed photo of the shim order just in case it was assembled wrong. (mine is attached)
      I know most people on here are going to be horrified I'm taking back to stock but any help on above would be really appreciated.

      I've read a lot of threads about this but still haven't found exactly what I'm looking for.  I'm pulling my 2004 DRZ400S out of storage sometime this week and getting it ready for the season.  I live at 9,000 ft, but my first ride of the year is probably going to be at around 5,000 ft.  I was going to pull the 145 main jet I'm running and put in the 150 adjusting the needle from the 2 clip to the 3rd, then re-jet once I got home.  I already have the extended fuel mixture screw in place so I started thinking that I should just run the 150 jet set up and adjust the fuel screw to compensate for the higher elevation where I'll be doing most of my riding.  I will be going down in elevation for rides until late May or June depending on snowfall, but riding on the street when I'm able.  Are there any disadvantages with this?
      I'm new to posting on this forum, so please forgive me if I didn't get the right search words in and there is already a post about this.

      Good Morning,
        Last night I measured my valve clearances for the very first time (I know...) on my DRZ400S.  It's a 2002 and I've owned is since 2011.  I bought it with t's got about 15,000 miles on it and most of it's miles these days are on dirt.
      Intake specs are 0.10-0.20 mm.  Exhaust specs are 0.20-0.30
      My intake valve clearances are in spec, forgot to write them down.  My exhaust valve clearances are between 0.1778 and 0.2032 which is slightly out of spec.  They are no more than 25 microns out of spec.  My question is, do I really need to shim these?  Will this kind of out-of-spec cause performance, mechanical, or other losses?  As far as I can tell, I'd have to buy a whole shim kit which is like $80.  Thanks!
