CRF250L Electrical/Electronic's Hookups and Accessories

46 posts in this topic

Seeing as we live in a electronics world with smart phones, GPS 's, heated gear, grips,12 volt camping gear...etc, etc... Figured it be a good idea to start a post and see how and what owners are gearing up for accessories to their LRP's.

Good place to discuss "rights and wrongs" for hooking up accessory power supplies and How much?... We can/should hook up.

I'll leave this in the hands of the Electrical Guru's before I comment and ask questions, as I'd like to know the right ways also:

I havent seen a figure for power output for the alternator. But assuming its 250w which is guess based on other similar size bikes. 55w is take up by the headlight. I dont know how much the engine management/fuel pump take up but id imagine a fair bit, perhaps 100w. If you put a set of Aux light at 35w each then you dont leave much power to refill the battery.

For some kind of reference, the new Triumph Trophy has an 800w alternator, which powers all the management, an ECU, RCU, Immobilizer/TPMS, Stereo, Traction/Cruise control, ESA, heated grips, heated seats, GPS and two aux power sockets, oh and it charges the YTX24BS battery

I remember seeing a bit about this somewheres:

From the Helm, if its any good to ya

Alternator Capacity-0.34 kW/5000 rpm

Charging coil resistance (20 C/68 F) 0.1-1.0 (ohm's)

I'll see if I can dig up more info. and got the service manual here if ya need any specs. Just let me know what ta look for...lol

well in that case id say you'd be fine to wire in your GPS and heated grips, in terms of wiring, i would run a lead from the ignition switch, to a relay and use the relay to power the accessories, I dont like drawing too much amperage through the ignition lead.

Aux lights can be wired to turn on with your high beams and/or manually. :smirk: A relay is also recommended(see above post) ;)

More info is available and will be posted later.... :cripple:

Ask away... :thumbsup:

Great thread, something I don't really know much about so thank you for starting this!

I wonder what I may have gained by doing the following...

1. Removed front signals (with running lights) and replaced with DRC LED signals (no running lights).

2. Removed rear signals, tag light and tail/brake light and replaced with DRC Edge LED tail/brake/tag light with integrated signals.

On my Triumph (and now I have a lead on my LRP too) to run Tourmaster Synergy 2.0 heated gear which has a big draw.

The items I have are...

1. Leather gloves = 24w/2a

2. Jacket liner = 64.8w/5.4a

3. Pant liner = 45.6w/3.8a

So my quetion is what should I be able to run on the LRP?

Thanks! :thumbsup:

Wow, I wouldn't run all that on the LRP and knowing how borderline the charging system in the Thruxton is I'd be cautious using all that on there too.

A good way to test whether you're taking too much out is this:

With the bike turned off, measure the voltage across the battery terminals, you should have around 12.5v in a good battery

Plug in/turn on your equipment, start the bike and measure the voltage across the battery again. You want at least .5v more when running than at rest to recharge the energy use to start the bike

And your not going to see much benefit with an LED light, the rear light is only a 5w bulb

Thank you!! :thumbsup: I have been running the jacket or gloves thus far on each bike, never used the pants. By the time I get my overpants with liner on it's HOT!!

Thanks for the test method, I will check on that and see where I am.

I have run my heated grips, vest and GPS off the battery all day with no issues.

In Canada we have and i assume its now the same everywhere, we have daytime running lights so all the lights are on, as well as the front signals.

I run everything off the battery direct, I know there is a risk of forgetting the grips on, but the wiring harness on the bike isn't really accessible and also don't want to cut into it.

The Oxford grips I bought are supposed to shut themselves off automatically.

It's funny how you guys are talking about heated grips, pants, liners. I'm thinking of hooking up a 2kW airconditioning unit. It's bloody hot here

Hahahaha

Great idea eye :thumbsup: I was thinking of a similar route. Did you purchase the Battery Tender lead and cig lighter socket all from the same place?

      Hi all
      I'm looking for any help with assembling my transmission. Does anybody have pictures or step by step guide they can share with me? I have the manual but it doesn't seem to be helping. A couple questions that stand out:
      Should all the shift forks marking face to the left?
      When the gears are all assembled without the shift forks installed, should the gears all line up and spin freely?
      I've assembled and disassembled this a couple times now and every time I try to run it through the gear on the bench it doesn't shift all the way up or down or the shafts will spin and then bind up.
      I have the service manual but find it very vague in this area.
      Please, any help would be appreciated
      Thank-you

      Hey everyone, I have a couple questions to do with me crf 250l not the rally. I am planning to go on a trip from BC Canada down to panigonia. I have to 250l right now totally stock and I need to know what I should do for exaust mods, power mods, things like that. I would like to be doing more highway type riding the way down. While in Mexico I will be doing some dirt road riding. But I need to know what I should do to upgrade the top speed, or do I not need to. Let me know what you guys think. Thanks in advance!

      Selling a complete Arrow exhaust system to fit a 2013 - 2016 Honda CRF250L.  Includes all parts pictured.  Has the factory installed DB killer but does not come with a spark arrestor.  I installed this system but removed it right away when I realized that I like the sound of the stock system.  Has about 2 minutes total running time on it.  One small scratch on the silencer from the cover bracket (see photo), otherwise like brand new.  Bought it from Italy for $465, will sacrifice for $340 plus $30 shipping to the lower 48 states.  Contact me for shipping to other destinations.  Prefer PayPal.

      Hey everyone, I am new to the world of 2 strokes and I am having an issue with a 1996 CR250r that I recently acquired. To begin with the bike will bog down when I first hit the throttle and will do so again if I let it sit for a bit.  However the problem goes away if I am constantly on and off the throttle.  The larger issue however is that the bike seems like it is hitting a rev limiter at 3/4 throttle and the power is lacking for a bike this size.  Id appreciate any help in trying to figure this out.

      2009 Husky WR 300.
      New top and bottom end.
      New brake pads and they were just bled. 
      Hyde skid plate.
      FMF Gnarly pipe and FMF Q-Stealth silencer.
      JD Jet kit.
      Comes with extra cylinder, head and piston. 
      Comes with lighter springs for the suspension.
      Pulls like a mule.
      This is an awesome trail bike. If you ride Georgetown, Foresthill, Elkins Flat or Chalk Bluff this bike will not let you down.
