Specs are compiled from manufacturer listings and verified buyer reviews and can change over time — please confirm the key details on the product page before buying.
Your Warrior 350 will only run as well as the carburetor bolted to it. A tired or wrong-spec carb shows up as a bog off idle, a hanging high idle, or a machine that needs half-choke to keep running. The seven replacements here all physically fit the YFM350, so the real decision is jetting, intake size, and how much tuning you are willing to do. Buy the one whose installed jetting matches your machine and your elevation, and most of the old running problems disappear.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Start with the fitment year range, then look at the main jet number and the manifold diameter. Those three details decide whether a carb idles cleanly on your quad or fights you every ride. Here is how the yamaha warrior 350 carburetor options stack up once you line up the numbers.
Top Picks
How To Choose The Best Yamaha Warrior 350 Carburetor
A Warrior 350 carburetor is a small gas-mixing device that bolts between the air intake and the engine head. It sprays a measured amount of fuel into the air your engine pulls in. When the internal jets and float are worn, that mix drifts and the quad runs rich, lean, or flat. The replacement has to match your machine’s intake size and your altitude to behave.
Match the jet numbers, not just the photos
The main jet meters fuel at wide-open throttle. The pilot jet handles the idle and just-off-idle range. One of the picks here ships with a 145 main jet installed and spares in #125 and #135, plus a 45 pilot jet and a 55mm air jet. If you ride near sea level on a stock machine, that range gives you room to lean it out or richen it as the plug reading tells you.
Check the intake manifold diameter
The manifold is the rubber or aluminum boot that joins the carb to the engine. If its inside diameter does not match your head’s opening, you get an air leak and a lean condition. One carb here lists a 36mm (1.42 inch) intake diameter and a 50mm (1.97 inch) air-side opening. Measure your old boot before you order and compare it to that number.
Know your year range
The Warrior 350 ran from 1987 to 2004, but some listings split the machine into earlier and later sub-ranges. One pick here is listed specifically for 1999-2004 Warriors, while others list the full 1987-2004 span. If your quad is a late model, that tighter listing can save you a fitment argument.

Detailed Reviews
1. Caltric Carburetor Yamaha Big Bear 350 Yfm350Fw
Our pick — 4.0+★ from 100+ verified ratings; the strongest balance of quality and price.
The replacement that starts clean and bolts straight up to the stock boot
If your Warrior has been sitting with a gummed-up original carb, this Caltric single-carb order is the closest thing to a straight swap. It ships as one carburetor with no extra parts to sort through. The listing covers Warrior 350 YFM350 across 1987-2004, plus Big Bear, Kodiak, Moto-4 and Wolverine models. That wide span tells you it is built to the common YFM350 pattern rather than a one-year oddball.
What wins people over is how it idles once it is bolted to the stock boot. The quad fires and holds a steady idle without the half-choke coaxing that sends most owners shopping in the first place. Fit is the second thing you notice — it seats against the intake without shimming or grinding. Caltric backs it with a 90-day warranty, which is short but covers the early failure window that matters most.
The honest catch is the value question. A few buyers felt the part did not justify what they paid once they had it in hand, so treat this as a dependable stock replacement rather than an upgrade. It is the pick for a rider who wants the quad running again with the least fuss. It is the crowd favorite here too, holding 4.0+ stars across 100+ ratings.
What riders get
- One carburetor, no parts sorting before install
- Listed for Warrior 350 YFM350 across 1987-2004
- Starts and idles cleanly once mounted
- 90-day warranty against early failure
Worth knowing first
- Some buyers question the value for the money
- Stock replacement, not a performance upgrade
- Compare the photo to your old unit before ordering
Reach for this if: you want the simplest path back to a running quad with a stock-spec carb and a warranty behind it.
Look elsewhere if: you are chasing more power or plan to re-jet — the NICHE assembly gives you spare jets to work with.
2. Caltric Carburetor Yamaha Warrior 350 Yfm350
Tighter year listing for the late Warriors, and the fastest bolt-on in the group
Late-model owners get a narrower fitment promise here. This Caltric is listed specifically for the 1999-2004 Warrior 350 YFM350, so if your quad is from that window the match is spelled out for you. The same part also covers Big Bear, Kodiak, Moto-4 and Wolverine as listed. It weighs in at 0.05 kg, which is a whisper — nothing about it feels like a brick bolted to the intake.
Installation is where this one shines: fifteen minutes to bolt on is the typical report. Fifteen minutes to bolt on is the typical report, and that is a stock-swap job most owners can do with basic hand tools. Value lands well too, with buyers feeling the part earns its keep. That combination — quick fit and fair money — is why it pulls the largest review base of any pick here.
Here is the trade-off to plan for. The throttle cable housing and the idle circuit draw mixed feedback, so budget a little time to set cable free-play and the idle screw after it is mounted. A few also note missing parts in the box, so count everything before you start. Compare the photo to your old carb, then treat the first ten minutes of tuning as part of the job.
The quick-swap case: fifteen-minute installs and a fitment listing aimed squarely at 1999-2004 Warriors make this the low-friction choice for a late-model quad.
Set aside tuning time: the throttle cable housing and idle adjustment are the two areas that need a careful hand, and a missing-part check before install saves a second order.
Pick it when: your Warrior is a 1999-2004 and you want the fastest bolt-on with a clear fitment promise.
Give it a pass when: you need the carb to be a turnkey no-tune affair — the cable and idle need a few minutes of setup.
3. Ruijie YFM350 Carburetor Yamaha
One box that covers the carb, the petcock, the filters and the manifold
Ruijie ships the widest parts bag in this lineup. You get the carburetor plus a fuel petcock tank valve switch, fuel filters, an intake manifold, a black throttle base cover and eight throttle base cover screws. For a rider rebuilding a neglected fuel system, that means one order instead of five. The bolt-on flange and gasoline fuel type are standard for the YFM350 family.
The longer warranty is the standout. Twelve months of coverage beats the 90-day terms on the Caltric units, and the listing explicitly invites a return if the carb crazes, spills oil, or stops working. The anodic oxidation finish on the body is claimed to resist heat and corrosion, which matters on a quad that sees mud and water.
Reliability is the mixed note, and it is the most-discussed topic on this listing. Some riders get a carb that works well; others hit repeat issues and describe the build as not a high-end part. That is a fair read for an entry-level kit — treat it as a solid rebuild bundle rather than a premium component, and lean on the 12-month term if yours acts up.
The bundle advantage: petcock, fuel filters, manifold, throttle base cover and eight screws in one box makes this the least frustrating rebuild purchase.
Build expectations: the finish is heat and corrosion resistant, but reliability feedback runs mixed, so the 12-month warranty is your safety net.
Built for: a rider rebuilding a whole fuel system on a budget, who wants every small part in one shipment.
Not ideal for: someone expecting premium internals — this is an entry-level kit with a long warranty, not a high-end carb.
4. Carburetor Carb & Air Filter Foam & Intake Manifold Boot Kit For Yamaha Warrior 350 YFM350X Carb 1987-2004
The kit that also replaces the filters and plug while you are already in there
This MOTO1988 box is aimed at the rider doing a full top-end clean-up. Inside: the carburetor, an intake manifold boot, a spark plug, a filter, an oil filter and air filter foam. For a Warrior 350 YFM350X from 1987-2004, that is most of what you touch on a fuel-and-air refresh in one shipment. The exterior finish is chrome, which is a nice visual touch on a visible component.
Owners repeatedly report it firing on the first try, with the carb matching its listed description closely. The performance story is the positive thread through the feedback, and the part matches its description closely. A 365-day warranty backs it, which is the longest term among the kits here and gives you a full season of cover.
Fit is where you should set expectations. Some report an exact fit replacement, while others needed to modify the boot or the mounting to get it seated. Value also splits — some find it worth it, others not. Check your OEM numbers against the listed 3GD-14101-00-00 and 1UY-13586-02-00 before ordering, and plan for light fitting work.
What it replaces in one go: carb, intake boot, spark plug, oil filter and air filter foam — a full air-and-fuel refresh for a 1987-2004 Warrior.
The fit caveat: some units drop in exactly, others need small modifications, so verify the OEM numbers and allow time for light fitting.
Reach for this if: you are doing a full refresh and want the filters and plug bundled with the carb and a year of warranty.
Think twice if: you want a guaranteed drop-in with zero adjustment — fit consistency varies across buyers here.
5. Carburetor w/Upgrade Aluminum Intake Manifold Replacement for Yamaha Warrior 350 YFM350 X Wolverine 1987-2004
An upgraded aluminum manifold replaces the rubber boot that cracks first
The stock intake boot is the part that usually fails on an old Warrior — it cracks and creates an air leak. This 1PZ package swaps it for a CNC aluminum intake manifold, which is machined rather than molded rubber. You also get the carburetor and a fuel filter. For 1987-2004 Warrior 350 YFM350 and YFM350X, plus the 1995 Wolverine YFM35FXG, the fitment is listed across the full run.
The aluminum manifold is the real upgrade here, replacing the crack-prone rubber boot. The quad starts right up after install, and the carb runs cleanly once the idle and cable are dialed in. Fit holds up too, with a typical install landing around thirty minutes. The machined exterior finish gives it a clean look in the engine bay, and the aluminum manifold is the real upgrade over the rubber boot on other picks.
Adjustability is the split. Some riders need no adjustments at all; others find the carb tricky to dial in. That is the nature of a carb mated to a new aluminum manifold — the seal and the cable geometry want a careful setup. Set aside an hour for tuning on top of the bolt-on time and this one rewards you.
Why it earns its spot: the CNC aluminum manifold tackles the crack-prone rubber boot directly, and a thirty-minute install gets you running.
Tuning reality: adjustability is the mixed area — some need no tweaks, others wrestle with it, so reserve an hour for dialing it in.
Choose it when: your old rubber manifold is cracked and you want an aluminum replacement bundled with the carb and fuel filter.
Pass it up when: you want a no-tuning drop-in — the manifold-to-carb setup rewards patience that some riders find tedious.
6. GOOFIT PV36 Carburetor Warrior 350 Kodiak 350 YFM350 BW350
Measured fit — 36mm at the manifold, 50mm at the air side, no guesswork
GOOFIT publishes the numbers you usually have to guess at. The manifold intake diameter is 36mm or 1.42 inches, and the air intake side is 50mm or 1.97 inches. Grab a tape and compare those two figures to your old carb before you order, and you remove the fit gamble entirely. The bolt-on flange and the 1987-2004 Warrior 350 listing cover the full run.
Riders report it firing on the first try with no jetting changes. It fires right up with no tuning needed, holds a smooth idle, and bolts on straight from the start. Adjustability, fit and idle all read positive in the feedback. The wear and corrosion-resistant alloy construction is aimed at keeping it stable in muddy off-road conditions.
The practical limit is the scope. This is a stock-pattern carb tuned for the YFM350 family, so it does not add power over a healthy original — it restores it. If your machine is stock and you just want it running like new, that is exactly the job. If you are chasing more punch, look at a carb with swappable jets instead.
The measured-fit appeal
- 36mm intake / 50mm air side published up front
- Fires right up with no tuning needed
- Easy install straight from the start
- Wear and corrosion-resistant alloy build
The realistic limits
- Restores stock power rather than adding to it
- Measure your old carb before ordering to confirm the 36mm intake
Best fit for: a stock Warrior owner who wants a measured, no-guess replacement that runs clean from the first start.
Skip if: you are building for more power — this carb restores the baseline, it does not raise it.
7. NICHE Carburetor Assembly For 1987-2004 Yamaha Big Bear Moto-4 Kodiak Warrior 350 400
The one that ships with spare jets so you can tune to your altitude
NICHE gives you tuning headroom no other pick here does. The carb arrives with a 145 main jet installed, plus spare #125 and #135 mains in the box. A 45 pilot jet is fitted, and the air jet is listed at 55mm. For a rider at elevation or running a modified intake, that spread of main jets is the difference between a quad that runs clean and one that blubbers rich.
It cross-references a long list of OEM numbers, including 3HN-14101-00-00, 2HR-14101-01-00, 3GD-14101-00-00 and 2XK-14101-00-00. That means it covers 1987-2004 Warrior 350 YFM350X along with Big Bear, Moto-4, Kodiak 400 and Wolverine. The polished finish and 2-year limited warranty round out a strong package.
The caution is the float bowl. Fuel leakage from the float bowl drain is the negative thread in the feedback, and quality splits between riders who find it excellent and those who call it cheaply made. Give the bowl drain screw a snug check before you fill the tank, and the running quality most riders describe stays intact.
The tuning kit you get: a 145 main installed with #125 and #135 spares, a 45 pilot and a 55mm air jet — real flexibility for altitude or mods.
Check the float drain: leakage from the float bowl drain is the recurring issue, so verify that screw is snug before first fill.
Worth it if: you ride at altitude or with intake mods and want spare main jets to tune with, backed by a 2-year warranty.
Look on if: you want zero-hassle sealing from the start — the float bowl drain wants a careful check first.
Know the Specs
Main jet and pilot jet sizes
The main jet controls fuel flow at wide-open throttle. The pilot jet handles idle and the first crack of throttle. A carb listed with a 145 main and a 45 pilot is set up for a stock-ish YFM350, and spare mains let you lean or richen the mix for your altitude or your intake. Match the installed jet number to your setup before you bolt the carb on.
Intake manifold diameter
The manifold joins the carb to the engine head. Its inside diameter has to match the port on your head, or you draw air past the seal and run lean. A 36mm (1.42 inch) intake diameter with a 50mm (1.97 inch) air-side opening is a common YFM350 spec. Measure your old boot and carb before ordering so the replacement matches.
