Gator parts YFM Carburetor Carb for Yamaha Grizzly YFM660 660 2002 2003 2004 2005 2006 2007 08 (YFM 660)

Fit this carburetor on my 2003 yamaha 660 grizzly. Side by side with the old mikuni, this china copy actually had a better finish on the casting. Some of the internals are not quite as robust, but you really need to look.New mikunis are between $300 and $500. I dont ride my quad as much as I used to so sitting takes its toll. This is the 2nd aftermarket carb I have installed on the machine. The first one lasted 7 years with intermittent sitting for months on end.If I am being completely honest, the old one is still good. I had an issue with it stalling at idle. A simple clean and gasket kit probably woulda fixed it. The problem is it was too hot and I was too lazy to do it. It was cheaper and much easier to just take the old one off, stick this one on and I was out riding again.The grizzly fired right up. I adjusted the idle and went tearing off across the countryside.Installation went smoothly, this carb is a direct fit on the grizz. I may install the provided extra size up pilot jet at some point as i noticed the transition from part to full throttle glitches a little. Its not bad, but its there. Keep in mind that this is with no adjustments other than idle right out of the box.The bottom line is, its a cheap fast way to get your machine up and running again. If this one dies in another 7 years....ill yank it off and put another one on.

For the money, it was worth a chance; and thus far that gamble has been gold. I have a 2004 Yamaha Grizzly 660. One of the local dealers here in AZ wanted $600 for a new carb....here on Amazon it was $58 with free shipping, which made my decision a no brainer. I’m not a professional mechanic and using a Clymer manual made this a relatively easy install. The jets that came pre-installed seem good for Arizona. I did not have to adjust the carb after installing it, idle speed was perfect right out of the box. I now have 30 miles through rough rocky terrain on this carb and it has functioned flawlessly. I’ll post an update after I get over 500 miles on it.

I have the fuel air mixture maxed out and it’s still running a little lean. There isn’t any adjustment on the main jet needle. I may have to figure out how to shim it..***update 8-13-20***I had to bring it to repair shop to help dial in the carburetor. Because it Just never ran right after outing it on. It was very sensitive to temperature. They told me to bring the original in as well in case they needed to borrow parts because aftermarket carbs usually don’t have all the proper adjustments needed.... they pulled the carb off and Took both carbs apart compared it side by side. The internals of this “Amazon” carb we’re way different than the original stock carb and would have always underperformed. The jets were smaller and the adjustments were too limited. They ended up using the stock carb, cleaning it up and borrowing the floats from the “amazon” carb. Now the thing runs amazing. In a nut shell, don’t waste your time. This is not even close to the specs and performance your stock carb had. From the outside they look the same but they are NOT the same.

Was not actually ordered for a Grizzly, but rather for a 660 Rhino. With simple modifications (was a breeze to convert) to the Rhino. Worked great!!

Put this on my 660 Griz, the original was so gummed up I couldn't rebuild it to make it work. This carb worked great right out of the box. I'm at 4,000 feet elevation and it came with a 145 jet (exactly what I needed for this elevation). It also came with a 150 and 155 for lower elevations. Keep the jets if your going to ride at that elevation. I did have to turn back the air (came at 4 turns) I adjusted it to 2 1/2 to get it to run perfect.

This was a replacement for a stock carb on an '05 Yamaha Grizzly 660. Went on perfectly, started up quickly after fuel bowl filled up. Only had to adjust idle. Will still be purchasing a rebuild kit for stock carb as a back up.

Worked good out of the box, but needed some fine tuning

It dropped right in, everything fit, and it started right up. So far it's been running fine. It's only 2x more than a rebuild kit, and it's a whole lot easier than a rebuild kit.
