    A friend of mine has an R1, that just dies, either on or off throttle, Everything is stock, after it dies, it won’t start until 20-30 mins of waiting.

    edit. Also it only does it on track. Can run in the parking lot with no problems. Not over heating

    any ideas? No codes thrown.

    Not sure if this applies to fuel injected bikes, but gas cap vent not allowing fuel flow due to vacuum created in tank?

    Yep we checked that.

    Did you check and reset the TPS? Has there been any tune or electronics flash, I know you said "stock"? Have you checked to make sure the throttle is opening correctly, one of the throttle stepper motors could be bad

    Nope it’s stock stock. That’s what he actually prides himself on. He runs fast af on a stock stock bike
    Well did anyways.

    Wow, that sounds terrifying for a track bike to be doing that.

    When you say "dies," are we talking any sputtering or anything or just turns off like a switch..........with the latter I would think an electrical issue happening somehow/somewhere.

    As to what that issue might be any why it's so temperamental is where the real challenge is.....

    This reminds me of older bikes with bad coils or CDI. Coil works fine when cold; bike heats up, coil goes bad, bike won't run until the coil cools down. Also an indicator of a bad connection in the harness near a heat source: Again, bike warms up, connection fails, connection is good when cooled down. "Self-resolving problem."

    Does this generation R1 have coils or a CDI? I mean, it has coils, but they are the "mount on the plug" style, right?

    I hate chasing intermittent electrical gremlins. I would disconnect, clean, dielectric grease, and reconnect every electrical connection in the ignition circuit as a staring point.

    Phl218 Lemme ask my wife

    my fuel injected husky did that right after i bought it (used)

    i took the whole fuel system apart, changed all 4 filters (1 in injector, also blew it out with carb cleaner in reverse; 1 in fuel line connector and 2 in tank).

    just to realize, that the connector of the fuel pump harness had the retaining clip broken off and the previous owner had loosely fixed it with a zip tie. i put a better warp on the zip tie and added another one and had no more stalling problems.

    That looks electrical to me. Kill switch?

    It seems electrical to me
    Also. And that’s what I thought,
    But nope not the kill

    crazy part is that I literally rode laps after laps in the
    Parking lot with it and couldn’t get It to do it

    Another vote for electrical issue. I had a similar problem with my bike, would run fine all day just cruising around, but
    once up to a faster pace, for a sustained time, instant off. My issue turned out to be the wiring harness. The wires near
    the regulator/rectifier had corroded enough to cause the problem.

    The wires became hot enough to discolor the insulation around the wires, so I had a visible indication of what was happening.
    No problems since I replaced the harness.
    I stripped the wires on the old harness and the corrosion stretched
    for almost a foot from the connector.

    Getting the same lean angles in the parking lot as on track?
    Or, it realized it can never win and just wants to die to end the agony.

    Defective or loose tip-over sensor?

    I talked to Jay and said it looks like it loses tach signal, and to check crankshaft and cam position sensors and the associated wiring.

    That looks like a fantastic way to get ass packed.

    Aren't these things super sensitive to voltage? Check battery and electrical system.

    Get it on a dyno to force a failure. A lot cheaper than a ambulance ride.

    Tip over sensor was my first guess, too. Tip over sensors are the debil.

    An owner of a "stock" bike can still be proud of that fact while also having removed unnecessary components. He's not running around with turn signals, mirrors and a kickstand, is he? For track duty, he might as well remove everything and anything that isn't critical for operation. Let's not get stupid, tho'...some things should be remain, like bodywork, or replace it with a crash-worthy aftermarket body.
    I get where your friend is coming from. I ran a stock CBR1000RR for years, very stealthy. It was gratifying to know that the guys with the "loud" bikes had no idea I was stalking them on track and, yes, coming around them made it even better.
