This all started because we wanted 'MORE POWER' lol
We bought a Moose Racing Stage 1 kit for the quad and had it installed & tuned by a local Arctic Cat dealer. The 454 ran stronger but the stock carb had a tendency to flood and run way too rich with the Stage 1 jets. The mechanic suggested opening the exhaust up so we picked up the one you see in the photos and replaced the stock muffler. It was louder and flowed better, but would still run like crap after about 30min. No power, too rich, smoking a lot, etc.

The issue was the carburetor. In 97 they built them for reliability and thus were built de-tuned. You could tune that carb to perform well hot or cold, but not both. So if you turned it to run well hot, you could barely get it to start cold.

The mechanic told us the DVX400 and Bearcat 454 ran nearly the identical engine in those years and putting the DVX 400 carb on it would be no problem and give the engine all the fuel/air it could ever want. We found a used dvx carb on ebay for $120 and delivered it to the mechanic. A week later we had the bearcat back and now it runs like a beast. The aftermarket exhaust kindof deteriorated after a few weeks so we put the stock exhaust back on and didnt seem to lose any performance at all.

It was all in the carburetor.

Now as for your 500~

I have a '00 500 manual and it uses a totally different carburetor than the '97. The stage 1 kit was all it took. Cheap and efficient.
I would get a service manual and take a look at the parts they use. The '97 454 uses a Mikuni while the 500 uses a Keihin carburetor.

It turns the 28's fairly well. Here is a video of him trying to climb a wet clay hill with them. Decent amount of wheel speed for a 454.

Clay hillside - YouTube

This video was taken before the wheel spacers, lift, and carb were replaced. Mostly just stock bearcat with 28's

A photo taken this past summer during our adventures.
We decided to sell off the 28" mud lites and put on a set of 27" sedona ripsaws. 12"w in rear, 10"w in front. Much better tires.

OK, I have a 454bearcat it idles and starts fine, but it has no top end it will only go about 25mph. Had it into the catdealer & basspro they cleaned the carb up but they are only trained on the newer models. It acts like its not getting enough air/fuel or both, there is nothing past 1/2 throttle. I looked up this dvx400 carb and found new ones for $150+/- for 2004-2008s models is this the carb you are talking about??
thanks.

Nice machine. I really like those lockable fuel tanks. I am thinking of buying one for my 2012 Sportsman 500 with the loc n ride system.

We had that happen on this bearcat once (before upgrade) Would start & run but was worthless. No power, etc. It was the needle & seat on the carb.

I would say the carb you mentioned would be the right one, however, i wasnt in on the actual purchase and we bought the model recommended to us by the AC dealer. I can find out what year it was off of specifically. I think 2004 though.

Hi everyone, long time lurker of this thread.. it contains a lot of valuable information. I don't know if I've ever posted on this forum actually.

I have a 97 4x4 Bearcat. I have had long term problems with the stock carb. It did not have the upgrade/recall add-on primer pump on the carb. I read this thread a lot and followed the plan used by OP raven437.

I don't have pics right now but I will post them up some time, showing how I installed the DVX 400 carb. My machine came to me kind of beat up and had years old gas in it, probably why I couldn't get it to start right no matter what I did.

The installation was pretty straight forward and if you can clean a carb you can install this thing. I removed the stock carburetor and boot, and loosened the 4 screws for the air filter box. The diameters of the carb inlet was different, but it would fit the factory manifold on the outlet with a small amount of silicone spray.

I used a 2004 DVX carb without the special intake pipe and without the TPS sensor. I bought it on ebay for $100. I also had to purchase a 2004 DVX thumb throttle and cable as the attachment is different and on the opposite side of the carb. The fuel line is larger so I replaced the line from the tank and installed an inline filter.

The tricky part was the intake boot on the carb. The stock boot will work, and so far this has worked for me. I trimmed the inside lip of the larger diameter hole on the boot with a razor so it would fit flush and tighten down nicely. On the intake side of the boot, I trimmed off the lip some so it would slide inside of the opening on the intake. I am using a small amount in clear RTV to seal that, along with with a clamp tightened slightly on the plastic lip of the intake box. It seems to be holding thus far.

It starts very nicely now and I have noticed a big improvement in drivability and acceleration. Top speed may have jumped also.

The throttle cable change to the DVX 400 setup was also a trick. The cable for some reason was slightly too short, so I had to remove the adjuster nut on the throttle cable input on the carb. Fully extended on the throttle adjuster and the carb.

So far so good, I will post pics if anyone is interested. I'm going to see how my intake setup holds up over time, but if OP is still around, it would be great to see how that boot is setup on yours.

EDIT: here are a few pics of my machine and the carb setup. Forgot to put the side panels on, oops.
