I did see a post, where you take the vacuum hose off of the petcock and give a suck on the hose to see if fuel is coming through to see if the diaphragm is leaking. I tried this and it’s like I’m sucking through a straw, I don’t know if there should be back pressure with this action but it felt like there was no pressure at all Shocked

got nervous that I was just inhaling gas fumes.

Not good, is it a new hose? they do leak after awhile.

Reply #16 - 07/18/22 at 13:42:16 I'm thinking the test leaves the hose on the petcock and off the the vacuum source. You want to test the petcock, so apply vacuum to the petcock and see what happens.

I think the test was to see if the diaphragm was leaking right? Justin, I’m going to look into that raptor petcock tomorrow. All the shops are closed Monday so I’ll see if they have them. If you have a part # that’d be great help.

Reply #18 - 07/18/22 at 15:56:17 Sorry, I don't have a number, but it's got to be genuine Yamaha Raptor 660 and not a Chinese knock off. There are smaller raptor ones so be careful.

I just took the carb back out and the air hose from the air filter is damp with fuel. Taking it apart now. Any information would be great if you’ve seen this problem before

Reply #22 - 07/19/22 at 14:24:54 I've seen it... usually when the rpm is too low and the valves don't close fast enough causing a little burp of fuel.

So up the idle screw? maybe because I’m having issues having it start it’s spitting through or need to get do more work? By the way, really appreciate all the help you guys are. I was part of this site way back when I first had the bike and you guys have all been awesome! Glad you’re still here!

Reply #25 - 07/20/22 at 14:29:01 One thing that I noticed is that when I did have it started for a short time, there was a lot of “rust” I’d imagine coming out from the connection from the header to the muffler. Don’t know if I’m saying that right but here is a picture of the build up.

Reply #26 - 07/20/22 at 15:13:17 sh!t happens, but if it's blowing out... you gotta leak. plug is rich, but if you've only been idling it... on choke... it should be. you wouldn't want to select a plug by this.

Reply #27 - 07/20/22 at 15:58:53 You can see from your picture that your idle mixture screw sticks out just a bit. That indicates that you either have it grossly misadjusted, or you have the wrong mixture screw installed. See how your screw is sticking out just a bit.

Reply #28 - 07/20/22 at 16:00:54 If it's the wrong screw, or if you have it turned out way too far, it's not gonna idle and it WILL run rich to da max. When correct, your screw will look like this, way down inside the hole.

Please check your screw and report its position. Turn it in until it bottoms. Use a light touch, just till it bottoms. Don't try to tighten it. Just turn it until it lightly bottoms. Report how many turns it was open. When things are correct it will be about 1-1/2 to 2 turns open.

BTW, if you want help and you appreciate getting the help, have the courtesy to perform the simple diagnostic checks advised and report the results back.

So, how many turns?

Take a picture of the screw when it's bottomed out and post it so we can see how far it went in.
