Please help electrical

Hey guys just got a head light for my 2012 yz450 only draws 3w so should have no problem running it but when I turn it on after the bike is running it just flickers and the bike stalls I have gone over the wiring even bypassed the switch still same problem I have directly wired it to the bike and still same problem any ideas

Have you installed a regulator?

The bike already has a regulator/rectifier.


Where, specifically, did you connect the light?

Where, specifically, did you connect the light?

i got the baja desighns harness and I plugged it in right behing the right radiator it looked like the right place because it had the same connecter as the harness and it was also roughly in the area the sheet baja desighns said it would be.

In that case, I think I'd contact BD about the matter, unless someone here has some input/experience with the stuff. 

I hooked up where I thought the harness from baja desighns told me to behind the right radiator the only place I see the same connectors that are on the baja desighns harness. The light flickers and the bike dies almost right away.

It's almost like my bike isn't generating as much electricity as it should and the light is zapping enough to kill the bike.

Ok it's the poly sport hmx light and baja desighns harness but I direct wired the light And still had the same problem so in my not not so great electric opinion that eliminates the harness and I also hooked the light up some where else before I put it on the bike just to see how bright it was and it worked fine.

Sorry about repeating information my posts where not showing up

Try powering the headlight off of a known good source such as your car battery. If it still flickers you've found your problem.

already did that before I hooked it up unless it went bad while hooking it up it works fine.

      Hey guys I just bought a bike last night. So the seller said the bike will turn on but then die. We didn't try it because it was really late at night and it was raining (seat was wet). But he said if you bump start it, it will turn on and ride. So what do you think the problem is? I just want to make sure it runs... I probably won't be able to bump start it till Saturday (rain)... It's a four stroke, and I know absolutely nothing about them. Thanks.

      I could use some feedback, My son is getting into off road riding so I have starting getting back into it as well.  We mostly do trail riding but did some MX track riding last year and he loved it andso did I.  I have a 2003 TTR 225, it's nice that it has an electric start but the suspension is too soft and it doesn't have enough power for my liking.  When I was riding the MX track I was having issues bottoming out on the larger jumps.  I want to change to a more off-road capable bike.   I won't ride it much and don't want to spend a lot of money, I think I prefer a 2 stroke, when I was younger, in 1990, I raced an 89 RM250 and loved it.  I am looking at a 96 RMX 250  and a 98 YZ400F, both bikes look to be in good condition and around a thousand dollars.  I like the RMX because I think kicking a 2 stroke 250 should be easier than a 4 stroke 400 and the simplicity of the 2 stroke engine.  The 400 sounds good because of the low end torque I assume it has but the cost of rebuilding the 4 stroke if needed worries me and I have heard they are hard to start. Should the RMX be decent for an occasional trip to an MX park?  Any thoughts on these two bikes?

      Brand new, still in the packaging Lexx end cap fits the stock muffler of 2006 & 2007 YZ450f and 06-13 YZ250f. Comes with a forest service approved spark arrestor and two different size tips. Don't spend hundreds of dollars on a slip on, this tip can be quiet and forest legal or loud and make power! Also a note for WR450 guys: get this tip and find a used 06/07 YZ muffler, fits directly on 09-15 WR450. $80 shipped free to the lower 48. PM, call or text 406-223-8789

      So I have a 2008 yz450f and I would like to add some LED lights to it to make it street legal. Mainly just a headlight and a tail light and turn signals if I need to (which where I live hand signals work).
      So where I need help is getting power from the stator to a battery. Wiring from a battery to anything else I got and understand and don't need help with (but recommendations are welcome). So my questions are.
      What type of power is coming from the stator. AC or DC? Will I need a regulator or rectifier? How do I wire something from the stator to charge a battery? What would that wiring look like? Would this stator work? Anything else I should know? Any help would be appreciated. Thank you.
