stator output

[FJR/V-strom trooper]

I am in the process of buying a DL650 and I am wondering when I start adding my electrics, how much left over wattage is there from running stock? I would like to add driving lights, electric vest, and my tankbag full of goodies. This includes GPS, radar detector, autocom unit and mp3 player. These usually take little or nothing to run but I am concerned about the driving lights and heated vest. Mike in Fremont, Ca.

You have about 100 watts to spare at cruising speed. In the daytime, you can pull the plug on one headlight and still have the desired triangle of forward lights. Use of 35 watt running lights instead of 55 is a good idea. They maintain the triangle too. The stock headlights are so good, you really don't need running lights to see, but to be seen.

Thanks. I had the same problem on the 03 FJR. I added an aftermarket stator from Electrosport and gained 100 watts, enough to run my lights.

How would you go about pullin the plug on one light. I have yet to pick mine up yet. Still on the fence whether I can afford one or not. Do both lights go on? Some bikes only one runs on low beams.

Some bikes only one runs on low beams.Stroms run with both lights on. Each has a low beam and a high beam. The connectors are easy to access, pull and replace.

Please tell me more about this aftermarket stator you speak of... :D

Go to Electrosport.com. The have aftermarket stators for more output. On my FJR I picked up approx. 100 watts and went in really easy. I see they have them for the SV650 which should fit on the DL. They are great to work with and on the FJR we got a group buty and save a ton of money. I would call and ask them. With all the electrics, aux. lights, heated clothing etc I would also be interested in the output now and the draw of the stock bike. I know what heated vest and aux. lights take.

Are they actualy shipping higher output stators for Vstroms? I know they have one for the DL1000 listed, but I've never heard from anyone who owns one.

I've emailed them about one for the DL650. Their response was to tell me to check back with them "in the future."

It's funny I am riding a Wee strom and looking at getting a FJR .! What do they say "Great minds think alike ,but fools never differ."

I think if you do get a wee strom and want to run a lot of electrics put a switch in the low beam line of one headlight.You can switch it off during the day and on again at night.Remember if you run a lot electric stuff like heated vests etc. simply turn things off a few minutes before you stop , then ideal the bike for a minutes. You will find any battery looses some of it's ability to hold charge in cold weather.

Cold weather is not something we get in Sydney Australia ,I have not even had a frost on the lawn in the morning ! About this time last year it was 114 degrees ,

I just got this e-mail in response to an inquiry at Electrosports.com:

"We already have a stator for the DL650 in the works, but not for the 1000. The stator is being produced now, and should arrive within a few weeks or so. Keep checking back with us, and I will let the big boss know that there is a market for these 1000 stators as well."

This sounds encouraging - also sounds like a group buy sort of thing might be a good idea when the new stator proves to be up and working.

I wonder what the output will be. Was drooling over the GS adventure yesterday afternoon for various reasons. Alternator output is 750 watts while the non-adventure model is a mere 600 watts.

....and no I'm not replacing my Vstrom. Adding to the stable is possible though.

Here is a little advice from one who has run all the stuff on a K4 wee. I would always have a voltmeter to monitor the status of your electrics. I used LED tail lights that save a little bit. I also then used Trail Tech HIDs (other HIDs would work but cost more than the trail tech) that use only about 18-19 watts each when running. I had heated grips and electric vest hook up too. GPS and radar detector used minimal amount. Of course, one doesn't run with all this on very often since it means you are running at night in temps requiring the heated gear. I found I do that but for a pretty low percentage of the bike's usage. At highway speeds I could ride with everything on that I mentioned and still be in the green with the voltmeter. At stoplights, it would drop to the orange or red range, but this shouldn't be a problem since it was only minute or so, but could turn off the lights or vest if bothered me. So the bike can handle it if set up right. It would be nice not to have to watch it like this (I don't even use a voltmeter on my ST1300 with huge alternator), but it is as it is.

I just got off the phone with Electrosport. The DL650 stators should be available in about 2 weeks. They are designed in house and manufactured elsewhere.http://i75.photobucket.com/albums/i291/jackpiner57/happy.gifThe output is reported to be around 360w!http://i75.photobucket.com/albums/i291/jackpiner57/clap.gif

[Mr. Fisherman]

How much, how much?
Oh, and is this 260 watts beyond stock?

Jeeeeze, they were 400 watts to start with!

[greywolf]

The stockers are 375W for the DL650 and 400W for 2003 and up DL1000s. Maybe they meant an additional 360W.

[jackpiner57]

Well, after further research I realize that I may have clapped prematurely.http://i75.photobucket.com/albums/i291/jackpiner57/rolleyes1.gif

According to Electrosport, the OEM DL650 stator actually puts out 286w. Their stator would give about a 75w increase.

On the DL1000 I don't know the actual OEM stator output, but they are claiming a 35% increase.They are out of stock and won't be getting them in for a couple of months. They have 200 on order from the manufacturer.

tmcgee, does this 286w info jive with what you have experienced? I know that you run a lot of juice draining accessories and have to remove a headlamp to get what you need. Would 75w extra be of any substantial help?

Getting an exact number for the power output of the real-world stator power output is difficult. The main fuse on the 650 is 30 amps, so at 13 volts, that's close to 400 watts total capacity. It's a reasonable starting place for estimating power loading.

Pat's number of 375 watts capacity seems correct, and 286 watts actually used by the 650 fits too, because when I try to draw more than 110 watts or so at speed, that puts me over the total power capacity of the bike and the battery stops charging.

Pulling a headlight connector gains 55 watts, so an 75 extra watts would be a help. It'd let me leave both headlights on and run a set of 35 watt aux lights along with the heated gloves and vest, and maybe even the heated grips. In the summer, without the heated clothing, I'd be able to run the 50 watt 2 meter transceiver without worrying if the battery is draining. Things like GPS, radar detectors, and such, are low power devices and inconsequential.

Tom, I agree with you 100%. I think that the 30 amp fuse is probably 2 amps generous as a cushion? I could be way off here, but it sounds plausible to someone with my lack of electrical knowledge. These calculations also assume the stock bike uses 286 watts to run it.

According to the service manual, the regulated voltage is 14v to 15.5v at 5000 or more rpm's. So, at 5000 rpm's it's probably 14v.

If we use 14v at 28 amps, that gives us 390 watts. That's 104 watts left for accessories. At 5000 rpm. With your 110 watt draw, you would have to do more than 5000 rpm's to break even.

But, every time the rpm's dip below 5000 there is a loss of voltage. So, 13v at 28 amps is 364 watts. That's only 78 watts left over for accessories. The battery drains at that point.

So using that as a guide, you should probably expect 49-55 real world watts extra with the Electrosport stator. Because when you are running under 5000 rpm's, you are losing that 26 watts or so of output.

I guess this is just my long winded way of saying "KEEP IT OVER 5000 RPM'S!":D

I used the calculator below for my calculations:

Fuses are sized with a bit of cushion in mind and power output is dependant on how fast the stator is turning, so this is why it's difficult to get exact numbers.

If the new Electrosport stators do have an extra 75 watts over stock, it won't be luxurious for me, but I'll take it. It's enough to power a set of 35 watt lights or an additional Gerbing vest.

[greywolf]

You mean how fast the rotor is turning. Stators are, um, stationary.;)

Well yeah! The caffeine has kicked in now.

[jackpiner57]

I'm pretty sure MY stator turns. In fact, I know it does.

Another 75 watts would be enough to ride with a full Gerbings suit on 2/3 heat, or a extra set of lights for night riding. I'd prefer 300 watts of overhead excess capacity but I realize thats a pipe dream. Anything extra would help, especially for when your touring. If the cost is reasonable then I'd say another 75 watts would definitely be welcome! At least we have more power than the KLR's. :)
