2009 IRS Big Bear 400 Elec help/Drawing needed

Recommended Posts

Hi everyone, been using these forums for quite some time as they're an immense help and tons of good info but am at a loss with this machine...

 

Have an 09 Big Bear with no fire.  Have run through the normal ohm tests and bypassing/ruling out components.  

-stator/pick up are within spec

-coil within spec 

-good CDI from running machine

Was able to get specs for components by crossing them to older models through parts fiches

 

Any help would be greatly appreciated!

I  know  it  may be simplistic, but did you try swapping  out the spark  plug ?.. One  friend beat himself  up  looking  for his  no  spark  problem  until  another  asked  him   if  he tried a  new  plug.. Sometimes it  is the simplest things that  trip  us  up.  That  is  on  our  first  check  list ever since when  there  is no spark.

First thing I checked as I've had lots of machines come to me with no ignition and was the culprit.  Usually pretty good with troubleshooting electrical especially on the Yami's and Honda's but this ones got me stumped.

To also add I've checked through the harness and connectors best I can for both continuity and resistance along with checked all the grounding points in the harness along with the grounds to chassis

Sorry for the late response, been busy with work.  I've literally checked over all components to see if they're with in range of spec as well tested the cdi in a running machine. Still no luck.

      Hey guys, Thanks for looking at my post. I haven't had a lot of experience with problems like this before, so I'm a little bit at a loss. The Quad was really hard to shift, (the dirty carb leaking gas making it idle high didn't help either). The only Idea I have would be is that the torsion spring is worn out, and that there is a normal parameter for how much it should move when those two arms of the shift shaft assembly spread apart.  That's my thought. Maybe someone who has more knowledge then me can let me know if i'm on the right track 😀

      '11 Grizz 700 here.  Since I've got some warm weather these next couple days I've decided to start the bike after about a year of just sitting.  Took out the plug and sprayed a good amount of fogging oil on top of the piston to help lubricate things.  After about a minute of letting it soak I stuck my air line tubing in to suck out the excess, but it seems like I didn't get nearly as much in return.  Repositioned the tube enough so that everything that was gonna come out pretty much did.  I'll probably shoot some compressed air down the plug hole before doing the start just to make sure it's all out, as well as cranking it for a second before putting the plug back in.   How long would it take for a bit of standing fogging oil to seep past the piston rings, and where would it go?  I guess into the engine oil?  The oil was fairly new the last time it was started but I'm sure it could stand to be changed after sitting for so long.  If much of this fogging oil got into the engine oil should I do the change before the startup?

      as many might know, the years previous, California had drought conditions that allowed "bark beetles" to basically kill many evergreen trees.
      here's an example of what they did:

       
      we had a few on our property... no HF tools here, this is Stihl guaranteed:
       
      lmk if anyone wants his #, I'm sure he'd trade for body work lol
