Default Alternator /stator output

I understand that the output is somewhere around 200-220 watts. I have a heated liner that uses 28 watts max, the heated grips I am not sure. The grips are the type that have a grid that sticks to the handlebar and the grip slides over it, Hi/Lo setting. They came from a snowmobile dealer. Will I over tax the stater using one or both or these accessories? I do a lot of cold weather riding.

Thanks, Mick

I believe the bike uses about 190 of the 220W just to run.
I rode all year for 3 straight years. I used heated gloves, helmet, and insoles (total of 20W IIRC) with no issue. I was also running a 28W LED light to brighten my way through the dark NH evenings when the sun sets around 4pm. With the light on I could see the battery voltage dropping. I just made sure to unplug a few miles before home to give the battery some juice back.
And speaking of being cold when riding, a small windshield is a great way to stay much warmer. Bar Mitts also helped a ton.
I've ridden in -25F and not much helps then. LOL

Good input, Maximus.
Mick - I use the same type of grip heater and for the one I use, the low setting just routes the power through a resister and doesn't actually save any energy. Just FYI that both high & low may be using the same amount of juice.
Having a volt meter is smart. You can get a digital one from ebay for a few dollars.

edit - my statement above is incorrect - low setting does save some power.

I don't agree with your assessment of the system. If the resistor was of infinite value, the load would be zero. Just say'in.

Interesting conversation. I caught all kinds of flack when I pointed out that bikes like the KLX had marginal charging systems when it comes to adding accessories. Seems they are.

I think it is possible to get a rewind for more power, but not sure.

Ahh, yes. Well done!!! My statement above is incorrect.

these are what I run: https://www.rockymountainatvmc.com/p...rip-Heater-Kit

I ran two 55 watt halogen cibie Oscar plus (very old school) lights with no problems on an ‘09 klx. I was gonna try a 100w bulb in one light but a member here Tremor advised against it as he had experience with over loading the electrical capacity on his bike. Baja designs rewinds klx stators for 130 watts output.
