Bike stalling out

Sometimes my bike will stall out. It happens when I'm at idle, and I blip/rev the throttle either when I'm just blipping it for fun, or taking off from a stop. It'll happen even when warmed up. Also, sometimes when I rev when moving with the clutch pulled in, it sounds like it'll choke for a split second and then be completely fine after.

Any idea of what this can be?

Fuel pump regulator -fpr, would be my first guess.
That's just what mine did when my fpr started leaking.

Mine has done it with old and new regulators. More so when cold. Might be able to clean it up with a good PC tune, otherwise bliping it is the problem I know, it fun and sounds neat but bike needs to be warm or it'll choke.

If it has been happening on a warm bike it very well could be the FPR.

1. Stop blipping the throttle.

2. Make sure your idle is set properly at normal operating temp > 180°

Mine was doing that recently. Every now and then at a light when stopped and in neutral. I give a quick blip before putting it in first and it would like cough, Or better yet more like a dull poof with an exhale at the end. It would start right up after but since reading this I turned up the idle speed closer to 1400 rather than the 11-1200 it was at before. It hasn't done it since. Just for clarification the blip was not the obnoxious gixxer squid "REV" type. Just the Hunt for Red October "One Ping Only" quick blip.

And completely unnecessary on a large displacement V-twin with a really heavy flywheel designed to keep the big lump turning over at idle...

Doesn't bother me if you want to add additional wear & tear on your transmission
