And that was when the trouble started. The bike has been running great since I bought it in November. I was unaware of the Prime setting on the petcock and may have been running it and leaving it in that setting. Adding to my issues, I ran misread the petcock and ran the tank dry while on Reserve. Dang! A farmer gave me some gas and the bike started but would not rev out of idle, which it would only do while fully choked (even though it was warm). After a few minutes of it running like this, it would only turn over and not start. I got it home on a trailer.
The air box was a puddle of thick, oily, gas stuff. I cleaned that out, swapped the spark plug, and changed the oil/filter, and drained the gas. The gas looked green and had a thick clear layer in the container at the bottom (water?). I removed the petcock, and flushed the tank with more clean gas.
I pulled the carb and cleaned it. The bowl drained out a mix of gas and some of that clear liquid. I just finished cleaning all of the jets and will install the carb tomorrow. I just hope the engine isn’t damaged. I want my bike back!

Does anyone have a link to the Yamaha Raptor petcock? My search on Amazon produced a variety of results that ranged in price.

Running out of gas is not damaging to an engine......only a bit demeaning to it.

There are a lot of Chinese clones to the OEM petcock.  They are a bit inferior as the brass outlet is machined and has a smaller ID than the original which has a formed tube from "drawn" brass.

Yamaha dealers can sell you the OEM petcock, or you can get one from eBay.  Be sure the listing has the part number and shows the white box....or you may be sent a Chinese copy.

Be sure it comes in a white box from Yamaha.  The fuel outlet should have a single flared end.

The photo in the Amazon link you provided has two machined ribs....that is a photo of the Chinese copy.

Gravity-style petcocks are simple.  I would be more concerned with getting one that fits properly than where I got it.

My bike had a cheap knockoff petcock on it when I bought it.  I worked fine.  only replaced it because the outlet was too small for the OEM fuel line.  I replaced mine with a genuine Yamaha part because I knew it fit.
