2005 Arctic Cat 500 4x4 snorkel kit & pipe


Recommended Posts

Sure I would be glad to help. Let us know a bit more information about your ATV. Is it auto or manual?

2" ABS pipe is usally used to snorkel the intakes. For the exhaust there is a mod to remove some of the restriction of the factory exhaust and then you can weld a flange on to run an exhaust snorkel. Because I have an aftermarket exhaust I used the flange on that. If you cange too much you will have to rejet but its no big deal.

Here are some pics of my 07 H1 auto to give you some ideas.




I was looking for a pic of the exhaust snorkel but can't find one. If your intrested let me know and I will get some pics and measurements.

with the 2 inch snorkels you do have to rejet the carb anyway. if im not mistaken.... I think 1.5 inch pipes you dont have to rejet

Yep that's correct. There are some exceptions but most cases if you are running fine a 1.5" air intake will keep you from rejetting if no exhaust work is done.

Also the belt intake and exhaust should never be under 2". This is only for the autos.

The best way to to figure out the jetting is to first tape over the intake so the opening is smaller and see if this fixes the problem. If this works then you need to rejet. If not you can have a leak somewhere in the carb intake. Another check would be to hold your hand over the intake, check for suction and see if the engine stalls. Is the 08 EFI or Carb? If its carb you have to rejet and if its EFI look for a powercommander or something similar. Feel free to PM me with questions because now that the weather is nice I am riding alot more then visiting the forums.

J I took the measurements from a post on highlifter from GWC a while ago but I kept dry fitting them until I got them the way I wanted. They are designed to be removed without having to remove the plastics. My Belt exhaust is up front some of the newer models are in the rear. But anyways here are some pics:

As far as jetting goes I took mine to a shop with a dyno to tune it in. Stay away from the stealer they don't know alot about anything aftermarket and you might void your waranty if you have one.

Here are the dimensions from Highlifter:

Transmission Top

1 3" to 2" rubber reducer (Home Depot) off top of tranny

1 long 90, one end has no neck, then

1 piece of 4 1/4" 2 inch PVC to a 2" by 2" rubber union (to aid in removing the carb at a later date. Tip from GWC), then

1 piece of 4 1/2" long 2" PVC to a 45, then

1 piece of 2" long 2" PVC to another 45, then

1 piece of 5 1/2" long 2" PVC to short 90, then

Run straight up to desired height.

Transmission Bottom

Factory rubber boot to a 3" to 2" rubber reducer (Home Depot) off bottom of tranny. Used thin wall sewer drain 3" as the connector between the factory boot and reducer, then

2" long 2" PVC to long 90, then

1 3/4" long 2" PVC to short 90, then

3" long 2" PVC to long 90, then

1 1/2" long 2" PVC to a short 90, then

Run up to desired height


Factory rubber turn upside down and insert 1 long 90 with no neck into end, then

Run up to desired location.

Other Tips

Trimmed my plastic to make sure there was enough room to run up all pipes.

Used lots of zip ties (best invention onthe world)

Didn't get in a hurry and test fitted many times before I glued it together.

Bottom tranny will install as one piece, so no need to worry if you nee to remove it after gluing it together.

Might should consider treaded unions as the last piece so you can change out different snorkel heights.

Have to cut one bracket to make the engine snorkel fit.

Bent brake line bracket back to make everything fit easier.

      Oil is getting in the air box from crankcase vent tube, I put the two hoses that go to the air box together then something started to smoke on the front of the engine. There is a filter? In the line I blew that out.

      What's the best kids atv out there? I've seen everything from the ones released by the major manufacturers to all those knock offs. Kawasaki has a KFX 50 that is pretty nice for under $1800...

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      What is the best engine oil to use for the Suzuki King Quad - also any other tips and tricks I should know before doing an oil change on these bikes 
    • By BruceG
      Hi guys. I have a problem where the quad will start and run well for about 5 minutes and then it dies. On inspection the airbox has oil in it (quite a lot). The oil is pumping through the cylinder head breather hose. This problem first happened suddenly. I have since done the top end including, piston, gaskets, rings and valves. I have also done the carb (not that I thought that this was the problem). The compression seems normal. The only thing that I can think of, is that I did not grind the valves well enough. Anyone experienced this? If so, how did you fix it? Any other thoughts?
