Review on High Performance Carburetor for Yamaha ATV 1987-1990 & 1992-1995 Moto-4 350 YFM350, Warrior 350 YFM350, Big Bear 350 YFM350, Kodiak 400 YFM400, and Wolverine 350 YFM35F - Perfect Fit & Reliable Performance! by Sean Bouchard

Two points: 1) This carb worked great on my '89 Big Bear, although I had to disconnect a throttle cable at the splitter that required it was about 30 extra minutes as i had to adjust the cable to get rid of slack as it is designed for dual cable operation. 2) Originally purchased a different carburetor from another seller with mixed reviews. The reviews said the float valve had problems and I had the same problem. I ordered this carb and there is a noticeable difference in how it feels and it works great! The air/fuel mixture screw was set correctly when delivered. For me, this is a first for third-party manufacturers. If you need a carburetor for your Big Bear 350, this is the one for you!
