Review on 🐊 Gator Parts YFM660 Carburetor for Yamaha Grizzly YFM660 2002-2008 by Dan West

I've reached the maximum air/fuel ratio and it's still running a bit lean. There is no main jet needle adjustment. I may have to figure out how to route it. ***Update 08/13/20*** I had to take it to the shop to help tune the carburetor. Because it just never ran right out of the box. He was very sensitive to temperature. They also told me to bring the original in case they needed to borrow parts as aftermarket carburetors usually don't have all the necessary adjustments. They removed the carburetor and disassembled both carburetors and compared them side by side. The internals of this "Revain" carburetor are very different from the original stock carburetor and it would only get worse. The jets were smaller and the settings were too limited. They ended up using a stock carburetor, cleaning it and borrowing the floats from the "Amazonian" carburetor. It's going amazingly well now. In short, don't waste your time. That doesn't even come close to the power and performance of your standard carburetor. Outwardly they look the same, but they are NOT the same.
