My 2021 Rebel CMX500A started stalling while I try to maintain a steady speed at around 1.2k miles. Despite me holding the throttle steady the bike erratically speeds and slows when I reach 2nd gear before eventually stalling out. All electronics keep working and no warning lights on the dashboard came on until the engine would stall at which point the oil light comes on because the engine is no longer running. Once the bike stalls out it will sputter but not turn over if I try to turn it on. I can only turn it on by revving but then it will keep stalling even if with the clutch pulled in unless I consistently keep revving which is very dangerous in traffic. After about 5 minutes of constant revving while riding the problem goes away and won’t happen again until the bike sits for approx. over 12 hours. I tried taking the bike to the dealer when it first happened but they had a 2 month waiting list and as my only vehicle at the time I couldn’t afford to bring it in. After finding many others online with a very similar problem who said shops weren’t able to find a problem when they took their bikes in they recommended I use seafoam. I used just a capful in a full tank of gas and the problem stopped for that full gas tank and one full gas tank after without seafoam. But by the second gas tank I filled without seafoam the problem started again. Afterwards I started putting one capful of seafoam every other gas tank and the problem went away for the time being. Once I finished the bottle of seafoam at around 2.5k miles I tried running the bike without it and it was working until around 4k miles when again the problem came back. At this point I took it to the dealership despite the waiting list since I now have another car but they’re warning me that, since the bike is currently running because of the seafoam, even though they believe it is the throttle body, if they cannot find a problem or Honda refuses to cover the work under warranty I will be stuck with the bill.
