2006 Arctic Cat 400 TRV (Green)


Recommended Posts

Hey everyone, I'm back again.  Some of you all may remember my posts.  I took last year off from working on this particular project.  It's a 2006 Arctic Cat 400 TRV (Green) 4x4.  I am at a loss as to why I cannot get it to run.  I have had someone suggest replacing the shift sensor.  Now, I have been looking in repair manuals and I just can't figure out where it's located.  I was told it was on the engine on the left side.  From the photo I found of one on eBay, I haven't seen anything that looks like it on the 4-wheeler.  Could it be called something else? Where is it located?  I know I'm overlooking it because I'm thinking it may have another technical name.  I feel that I will be making more posts asking for help once it warms up here.  I would really love to get this dang thing running this Spring.  I have 2 other different atv's that are requiring my attention.  So, I would really love to check this Dag blasted thing off of my repair list.  Any and all help will be greatly appreciated.  Thank you in advance.

That could be it. It did find that part on eBay when I searched for it. I wonder if that could really be the reason why I can't get it to start again?! When my dad (it's his ATV) first got it, it would start and idle but when you tried giving it gas, it would bog down and die. Then the starter got too hot, and it didn't start anymore. I have replaced a lot of parts including the starter, carb, stator, flywheel, fuel pump, bc and I don't know what else off the top of my head. There isn't much else left that it could be that I haven't already replaced. What else could it be?

Have you been using and following the service manual ? That will tell you what to check and it will lead you through a logical progression of steps to diagnose the problem.

Basically an engine needs three main things to run, compression, fuel and a spark at the right time..

Is the engine cranking over at a good speed when you use the starter ?

Does it have a good blue spark ?

If you try to start it, does the sparkplug get fuel on it ?

From what I remember, it's a yes to all of the above. It's been a while since I worked on it, so I can't really remember everything I've done. I'm going to try working on it again soon. Maybe within the week when weather permits. So, once I do, I will update this post with what I've found or haven't found. I bought an OEM neutral switch, so that's going to be one thing I replaced to see if it works. Here's hoping to warm weather next week.

      Have a 1998 AC 300 2x4, Just installed a new carburetor. Engine starts easy but the choke RPMs are very hi and take along time (5-10 mins when cold out). After engine has warmed up choke releases and it idles and runs fine., It does no have an electric choke. The choke lever is never used and it seems like an auto choke? Long story short, how can I lower the choke rpm levels?
      Also, carb came with a spare145 jet, not 100% sure what is installed. Could this impact choke RPMs?
      Any help and information greatly appreciated.

      Hey all,
      I need some input on a problem I'm having with my Kodiak 400 that keeps fouling plugs. First off, I've done a lot of work to this thing, most of it all in good fun. Brake work, cv joints, u joints, carb kit, checked valve lash, compression good, changed all fluids, etc... My problem is it keeps fouling plugs very quickly. I can put a new (manual recommended plug) in and it starts right up, runs great, idles great, picks up good. Doesn't stutter at all. I ride it for 1/2 a mile, it cuts off and won't start back up. I let it sit overnight thinking maybe it got to hot. Try to start it the next day, nothing. Put a new plug in, fires right up, runs great for another 1/2 mile or so, dead. The plugs come out and look carbon fouled with dry black soot on them. I don't know if this is a fuel/air mixture problem or a ignition problem. A couple of things that I noticed is I never need to pull the choke out to start it. Also, when it starts it automatically idles high like an automatic choke would do, then it comes back down to a good idle. Also I noticed that the air/fuel mixture needle valve screw does nothing when I adjust it in or out. I can screw it all the way closed and the motor still runs and idles good. Any advice would be greatly appreciated. I'm almost leaning to a ignition breaking down the plugs??

      Hello I’m new here and was wondering is anyone knew of good replacement part numbers for front struts and rear shocks for this atv? I think I’ve found a new rear shock, that looks like the original but there is no dimensions or anything and was wondering if there are any afterMarket new front struts available. I know it’s a long shot but any help would be appreciated.
