    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    BUEOD. Change the oxygen sensor. No difference. Changed the Fuel Injectors a week ago, 2-3krpm is noticeably smoother, and haven't experienced any hesitation after 100 miles. I will ride again this weekend to confirm the issue is 100% gone. I'll post a picture of the oxygen sensor and explain...

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    Set the AFV to 100, along with the minimum and maximum, and hesitation was 110% gone. Bike rode much much smoother through closed loop (2-4.5krpm). However, I tried an AFV of 96, 93, 90, and the bike "seemed" to pull the hardest/way more rev happy through closed loop at an AFV of 90 despite...

    No, I do not have the breather mod. Yea, rear plug looks suspicious.

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    I have yet to set the AFV to 100. How long will the AFV stay at 100 if I don't disable closed loop? I'm shying away from saying it is the oxygen sensor because it appears to be doing its job. Plugs look relatively good. I think it maybe the fuel injectors or o-rings around them that are...

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    So as mentioned before, I installed the OEM spark plugs and the bike's main symptom, hesitation between 4-4.5krpm, was significantly reduced. Occurrence dropped from 80-90% to 5-15% of the time. AFV is now 90% vs 82%. I normally road the bike on and off for the past 2 years. After recently...

    Left spark plug in both pictures is the front spark plug. Right spark plug in both pictures is the rear spark plug.

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    Yea, my theory as well. During closed loop, the oxygen sensor is compensating for a problem. Since the AFV is significantly different between closed and open loop, I am noticing a blip or hesitation in power. My AFV was 82%. So the oxygen sensor is sensing a rich condition in the exhaust and...

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    I read in the electronic diagnostics manual that an oxygen sensor reading below <0.41 indicates a lean mixture and a reading of >0.56 indicates a rich mixture. I have no clue if I am using ECMdroid correctly however I had my bike idling and the O2 sensor reading was fluctuating between 0.1-0.7...

    Thank you for the detailed information gentlemen. I just ordered the BUELLtooth ECM Interface off of www.buelltooth.com. I look forward to using it and hopefully it comes in sooner than later. I will keep you guys updated with any information/questions I may have. Lunaticfringe, with regards...

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    Hello friends. Two years later and I am still dealing with the same issue. Now that the coronavirus is giving me more time at home, I want to fix this issue immediately. I need your diagnostic help. Everything that I said in the original post applies. To clarify, it is not a complete loss of...

    Very noticeable flat-spot/sputtering in power-band between 4-4.5krpm

    Hello, When I bought my 2008 xb9sx (6+ months ago), I noticed a flat-spot in power-band around 4-4.5krpm. It's been getting worse and more noticeable ever since. It happens when I am using normal throttle operation, 50% roll on, to WOT operation, 100% roll on. (With the WOT roll on, the...

    Anyone in the NJ area?

    Unfortunately I don't have an entire day to spend this weekend but if anyone is down for a 2-3hr ride around central NJ, I am down.

    Anyone in the NJ area?

    Nothing happened. Which upcoming races? When and where? Let's make something happen. The nights are becoming cold and winter will soon be upon us...or a hurricane lol.

    First Buell (2008 XB9SX)

    The voltage regulator doesn't get that hot, or at least to my knowledge, so why not put it off to the side. There's enough room and enough length in the cable. It will still get air but the front cylinder will have a lot more cooling. The biggest frontal air blockage to the front cylinder is the...

    Anyone in the NJ area?

    The golden Nissan GTR, maybe, I wouldn't know though. I see it parked at Raritan Valley Community College all the time. I've also seen a golden Audi R8 parked in the same location before. PM me if your interested in riding this weekend. I'd be more than happy to. I specifically want to compare...

    The Buell effect

    So far, after owning a Buell for only about a month, the individuals who ask questions or comment on the bike are those who have already ridden a Buell. The conversation always ends up the same, "This bike is so much fun. You must have a blast on it".

    Anyone in the NJ area?

    Oh snap, I know the roads are really good around hopewell but I'm not too familiar. If you could come up to Bridgewater, I'll show you a nice route. Nonetheless, we gotta meet up. How's this upcoming Sunday looking like for you?

    First Buell (2008 XB9SX)

    I haven't found the bike to be quirky at all and nothing vibrates more than a solid mounted parallel twin lol. No one is snapping belts, that's good. I plan on keeping the bike bike as stock as possible, perhaps even keeping the breather tubes in the same place. The previous owner didn't know...
