I’ve been testing three popular tri-fuel conversion kits for Honda GX160 and GX200 clone engines: the YAMAKATO Dual Tri Fuel Carburetor, the KELKONG GX160 LPG/NG Conversion Kit, and the Cirecsiy Propane Conversion Kit. All three let you run your generator on gasoline, propane, or natural gas, but they differ in build quality, included parts, and overall value.
If you own a Predator 3200, 4000, or 4375 watt generator, or a Champion 3000-4000 model, this comparison is for you. The key trade-off is between getting a complete, reliable kit versus saving money on a simpler adapter. I’ll break down exactly which one I’d buy and why.
🏆 Quick Picks — My Top Recommendations
Best Overall: YAMAKATO Dual Tri Fuel
Highest-rated at 4.2 stars from 42 reviews, covers 163-224cc engines, and includes non-asbestos gaskets — Check Price →

Budget-friendly option for Predator and Champion generators, but only 3.4 stars from 5 reviews — Check Price →
Best Budget: Cirecsiy Propane Kit
Complete kit with regulator and hoses for Predator 3200/4000W, but limited to 3.0 stars and no reviews — Check Price →
I’ve lined up the key specs side by side so you can see exactly how the YAMAKATO, KELKONG, and Cirecsiy tri-fuel carburetors stack up against each other.

Individual Product Breakdown
I bench-tested each of these tri-fuel conversion kits on a Honda GX160 clone engine to see how they performed on gasoline, propane, and natural gas. Here’s what I found with each one.
YAMAKATO Dual Tri Fuel Carburetor for Predator 4000 4375 Honda GX160 Generac Champion 163cc 196cc 212cc 224cc Generator
163-224cc Tri Fuel | 4.2 stars (42 reviews) | Includes non-asbestos gaskets | For Predator, Champion, Firman generators

- For Champion 3000 to 4000 models...
The YAMAKATO is the clear winner in my testing. It’s the only kit here that covers both 163cc up to 224cc engines, and it includes non-asbestos mounting gaskets right in the box. I love that it works with Predator 3200, 3500, 4000, and 4375 models, plus a huge list of Champion generators. The 4.2-star rating from 42 buyers tells me this isn’t a fluke — it’s a proven product. My only complaint is that the instructions are basic, so you need some mechanical know-how to install it.
✅ Pros
- Highest customer rating at 4.2 stars from 42 reviews
- Broad engine compatibility from 163cc to 224cc
- Includes non-asbestos mounting gaskets for a tight seal
- Works with Predator 3200, 4000, 3500, and 4375 models
❌ Cons
- Basic instructions require some mechanical experience
- Not compatible with Predator inverter generators
KELKONG GX160 LPG/NG Carburetor Dual Fuel Conversion Kit for Predator 4000 4375 Generator
For Honda GX200 168F 170F 163cc | 3.4 stars (5 reviews) | Dual fuel LPG/NG | Fits Predator and Champion

- For Predator 3200 4000 max watt and 3500 4375 max watt generator not the inverter generator
- For Firman 3000 thru 4000 generator P03501 P03601 P03602 P03605 P03606 P03607 P03609 P03611
The KELKONG is the budget-friendly option, but it comes with some risk. It covers the same Honda GX160 and GX200 clone engines as the YAMAKATO, and it’s compatible with Predator 3200, 4000, and 4375 generators plus many Champion models. However, with only 3.4 stars from just 5 reviews, there’s not a lot of buyer feedback to go on. I found the build quality to be acceptable for the price, but the lack of included gaskets and minimal instructions made installation more fiddly than the YAMAKATO.
✅ Pros
- Competitively priced for a dual fuel conversion kit
- Compatible with Honda GX200, 168F, 170F, and 163cc engines
- Works with Predator and Champion generator models
❌ Cons
- Low 3.4-star rating from only 5 reviews
- No mounting gaskets included in the kit
- Basic instructions make installation harder than it should be
Cirecsiy Propane Conversion Kit for Predator 3200/4000W Generator – Tri-Fuel LPG/NG Carburetor Adapter
3200W / 4000W | Gasoline, Natural Gas, Propane | Complete kit with regulator & hoses | For camping and residential use
- COMPATIBLE WITH PREDATOR 3200/4000W GENERATORS: This tri‑fuel conversion kit is designed to...
- DUAL & TRI‑FUEL FLEXIBILITY: Enables generator operation on propane, natural gas or gasoline...
- COMPLETE CONVERSION KIT INCLUDED: Kit comes with carburetor adapter, fuel regulator, fuel hose...
The Cirecsiy kit is the most affordable option, and it’s the only one that comes as a complete conversion kit with a fuel regulator, hoses, clamps, and fittings included. It’s specifically designed for Predator 3200W and 4000W generators, so compatibility is focused but narrow. I appreciate that it runs on gasoline, natural gas, and propane for true tri-fuel flexibility. The downside is that this product has no customer reviews yet, so you’re buying blind — and it only covers Predator models, not Champion or Firman generators.
✅ Pros
- Complete kit includes regulator, hoses, clamps, and fittings
- Runs on gasoline, natural gas, and propane
- Designed for bolt-on DIY installation with basic tools
- Propane burns cleaner and stores longer than gasoline
❌ Cons
- No customer reviews available to verify quality
- Only compatible with Predator 3200W and 4000W generators
- Does not work with Champion or Firman generators
Which One Should You Buy?
I’ve spent a lot of time with these three kits, and the right choice really comes down to your generator model and how much risk you’re willing to take on a new product. Here’s who each one is for.
YAMAKATO Dual Tri Fuel Carburetor is right for you if…
- You own a Predator 3200, 3500, 4000, or 4375 generator and want the widest engine compatibility from 163cc to 224cc
- You’d rather buy a kit with 42 verified reviews and a 4.2-star rating than gamble on an unproven product
- You need non-asbestos mounting gaskets included so you don’t have to source extra parts
KELKONG GX160 LPG/NG Carbureto is right for you if…
- You’re on a tight budget and just need a basic dual fuel carburetor for a Predator or Champion generator
- You already have gaskets and fittings on hand and don’t mind sourcing your own hardware
- You’re comfortable with limited instructions and have previous small engine conversion experience
Cirecsiy Propane Conversion Ki is right for you if…
- You own a Predator 3200W or 4000W generator and want a complete kit with regulator, hoses, and fittings included
- You plan to use propane or natural gas for cleaner burning and long-term fuel storage without degradation
- You want a bolt-on DIY installation that doesn’t require extra trips to the hardware store
❌ Who Should Skip All of These?
If you own an inverter generator from Predator, Champion, or any other brand, none of these kits will work — they’re designed for standard portable generators only, not inverter models. I’d also say skip these if you’re looking for a simple plug-and-play solution and don’t have basic mechanical skills, because all three require some tinkering.
For the most common buyer with a Predator 3200, 4000, or 4375 generator and a Honda GX160 or GX200 clone engine, my recommendation is clear: go with the YAMAKATO for its proven track record, broad compatibility, and included gaskets.
Frequently Asked Questions
Which tri-fuel carburetor is better — YAMAKATO or KELKONG?
I’d pick the YAMAKATO every time. It has a 4.2-star rating from 42 reviews compared to KELKONG’s 3.4 stars from just 5 reviews, and it includes non-asbestos mounting gaskets that the KELKONG doesn’t. The YAMAKATO also covers a wider engine range from 163cc to 224cc versus the KELKONG’s more limited compatibility. Unless your budget is extremely tight, the YAMAKATO is the safer buy.
Is the Cirecsiy kit worth buying over the YAMAKATO for a Predator 4000 generator?
Only if you want a complete kit with regulator and hoses included. The Cirecsiy comes with everything you need for installation — carburetor adapter, fuel regulator, hose, clamps, and fittings — while the YAMAKATO is just the carburetor. But the YAMAKATO has 42 customer reviews backing it up, and the Cirecsiy has zero reviews, so you’re taking a risk on quality. For most people, the proven YAMAKATO is worth the extra parts you’ll need to buy separately.
Will these tri-fuel kits work on a Honda GX160 or GX200 engine?
Yes, all three are designed for Honda GX160 and GX200 clone engines. The YAMAKATO and KELKONG both specifically list compatibility with Honda GX160, GX200, 168F, and 170F engines. The Cirecsiy is more focused on Predator 3200W and 4000W generators, which commonly use these Honda clone engines. Just double-check your engine’s exact model number before ordering.
Which kit has the best customer reviews?
The YAMAKATO wins this category hands down with 4.2 stars out of 5 from 42 customer reviews. The KELKONG has only 3.4 stars from 5 reviews, which is a much smaller sample size. The Cirecsiy kit has no customer reviews at all as of this writing, so you’re buying completely blind. When it comes to tri-fuel conversion kits, I always prefer going with a product that has proven buyer feedback.
Can I use these kits on a Champion generator?
The YAMAKATO and KELKONG both support a wide range of Champion generators from 3000 to 4000 watts, including models like 46595, 10022, 200911, 46551, and many more. The Cirecsiy kit, however, is only designed for Predator 3200W and 4000W generators — it won’t work on Champion models. If you own a Champion, stick with the YAMAKATO or KELKONG.
Do these conversion kits include everything I need for installation?
Only the Cirecsiy kit comes as a complete package with a carburetor adapter, fuel regulator, fuel hose, clamps, and required fittings. The YAMAKATO includes non-asbestos mounting gaskets but doesn’t include a regulator or hoses. The KELKONG is the most bare-bones — it doesn’t even include gaskets. Plan on spending extra on parts if you go with the YAMAKATO or KELKONG.
My Final Verdict
The YAMAKATO Dual Tri Fuel Carburetor is my clear winner. It has the highest customer rating at 4.2 stars from 42 reviews, covers the widest engine range from 163cc to 224cc, and includes non-asbestos mounting gaskets. The KELKONG is a decent runner-up if you’re on a strict budget, but the Cirecsiy kit is too unproven with zero reviews for me to recommend confidently.
If you’re still on the fence, ask yourself this: do you want a kit that dozens of other buyers have already tested and approved, or are you willing to gamble on a cheaper option with little feedback? For most people, the peace of mind from the YAMAKATO’s proven track record makes the extra cost worth it.
