So I have roughly 500 miles on my bike and whenever I go to hammer on it there is a very bad jerking/cutting out happening in just about every gear around 7-8k rpm’s. It’s like traction control is trying to kick in, but it’s shut off completely. I’ve heard it may be a spark issue such as a bad coil pack or maybe a spark plug. Any help/advice would be greatly appreciated. Thanks.

Want to say I believe I read about something very similar on the board but couldn’t find it. Someone else may chime in. |

The bike is flashed and I have an exhaust on it. I’ve owned 2 mt10’s before this and never had a problem

Who flashed it? Was it doing it before the flash? Any CEL on?

It was flashed by 2 wheel dyno works. I unfortunately don’t know if it was doing it before the flash because I never rode it prior to getting it flashed. But I have a feeling it’s an electrical problem such as a failing ignition coil

But I have a feeling it’s an electrical problem such as a failing ignition coil Is there only 500 miles on the bike total? If so that's way early for a coil to be failing. If it's got more miles then it's possible but uncommon. I'm at well over 10k miles on my 2019 and have zero issues apart from the OS FTECU blipper. Try contacting 2WDW, Nate is super helpful with things and might be able to point you in the right direction. |

Yes there’s only 500 miles on it. I’m at a complete loss, no clue where to even start looking. It only happens around 7000 rpm and only with wide open throttle. If I just bring the revs up slower it won’t stutter.

If I just bring the revs up slower it won’t stutter. Definitely shoot 2WDW an email and see what they say. Tough part is not knowing if it was doing it before the flash or not. On the plus side it only has 500 miles so it should be under warranty if it is a coil pack or something. |

Unfortunately Nate at 2wdw did have much help to give me. I pulled the tank last night to look for any plugs that might be loose and unplugged both my o2 sensors for my exhaust so that might help, doubtful but worth a try. Next step is clean the tps plug and possibly changing coils

Have had some trouble with my 2018 too. 2wdw flash unlocked power, but the throttle response was razor on/off and felt downright dangerous cracking the throttle leaned over even in 3rd gear. Tried throttle tamer, modes, etc. Contacted them a couple times, they didn't know and said they'd call back but no call back. Gave up.
Sent ECU to vcyclenut, and all was great except when whacking the throttle open at 4000 RPM resulted in terrible bogging. He tried his best to resolve the issue but it'd only run right with a stock flash. Got a refund and a stock flash.
Checked the voltages on the TPS/APS sensors and they were almost dead on to each other, in spec, no strange behaviors. Thought for sure they were mis-calibrated but no.
Can't justify spending cubic dollars on this so I gave up and will have to stick with the soggy stock flash with its weak 1st, 2nd gears and big 7000 RPM power surge.
Frustrating.

The warranty will cover it as long as they can't say that the flash is causing it. The words straight from the dealers mouth to me last weekend when I was dealing with my wife's bike, "you cannot void your warranty, but they can choose to not cover something"
Flashed but kept the O2 sensors? If those are disabled then a dealer might have a hard time determining that the cause of whatever is going on is not the flash. They would probably have to do a little more physical troubleshooting than just plugging their stuff into it and letting the machine tell them what it's doing since you have it remapped. If you're able to go back to stock mapping without too much trouble I would do that before going to the dealer just to be sure it's not from what you've done to it.

Might be worth it to have the ECU set back to stock and plug the O2 sensors back in and see if it still does it. |
