07 attak Shuts off when stopping

[Yamaha4life1990]

Sled runs awesome but when I'm riding and come to a stop at an intersection the sled dies unless I lightly feather the throttle for a few seconds then itll sit there and idle. No codes flash and when it dies I can fire it right back up.

I know it sounds silly. Did ya check the plugs?

What’s the mileage?

Yeah, check your plugs, some owners has had similar problems caused by the ignition switch, or fuel relay with some corrosion, also grounding blocks, mice can play hell with wiring also, came across a buddy on the trail the other day with a Attack, sled would start but soon as he moved ahead engine would shut off, was very sad to see him being towed out by a Cat.

What’s the mileage?

Probably lots. Sounds like that common idle problem many apex get as they age and rack up miles.

X2..

So once it stabilizes, if it does, what is the idle speed?
There are those four synchronization screws, they can be used obviously for sync, but also to alter the idle speed.

There have been threads on this issue already. Some suggest checking valve clearance which is a good idea. If they lack clearance, when heat soaked(like after a full throttle pull), they can be held slightly off their seats by a thousandth or two. Once the heat of the valve lowers, it shrinks and touches the seat, sealing up.
When valves don't seal, it is most noticed at idle RPM's.

Unless this has been going on for a while, I'd give it a chance to remedy by itself before you do any changes. It might just be your gas or something temporary. I had that exact problem on a one day trip all day long about four years ago, read all the reports on here, but it never happened again.

Mine does that but only when cold. Pulling out of the trailer... coming to the first few stops. idle would drop and it would die. Once warm I don't have much of an issue. CO adjustment was the fix for me but I think I am really in need of a valve adjustment.
