    added a few mods

    Have you run the bike since polishing the headers? Just wondering if the color will start to turn when they heat up.

    Help - Bike starts but stalls on idle and won't run.

    gtp3800 - I added Seafoam about two days ago and psychologically want to believe it's running a little better, but it still stalls. I haven't cleaned the plugs after trying to start it mulitple times (probably at least a dozen) so I'm going to pull them and try that next while hoping the...

    Help - Bike starts but stalls on idle and won't run.

    Hi all: I've dug through as many posts as my Google search can come up with, but can't find the answer to my Buell's problem... please help! Coming out of winter I decided to install a Jardine exhaust, K&N filter, race map (via ECMspy) and change the oil on my 2004 XB12S. My bike also has...

    Static Timing

    I got the map from someone who gave me ECMspy. I checked it against another source before burning it. The bike did run for a few days with this map installed. I'd love to do an intake manifold leak, but I can't get the bike to idle for more than a few seconds... This should also make the bike...

    Cam position sensor output - for future reference

    I posted a message yesterday regarding what you should see from the cam position sensor when doing a static timing test. I found my answer so I thought I'd share it in case anyone else comes across the issue in the future. I was doing a static timing test per the service manual/ECMspy...

    Static Timing

    Nevermind... I came across some helpful commentary in the service manual that describes the fact that there are six tangs on the rotor cup that block the magnetic field to the cam position sensor - so for each full rotation of the cam you should see six sensor transitions. I didn't count, but...

    Static Timing

    I've reset TPS multiple times over the past few days with no improvement. Ironically, everything went really south (won't idle/run) after doing the first TPS reset. But all of the TPS #'s look good according to ECMspy (right set point and behaves well while moving the throttle). I didn't...

    Static Timing

    Hey everyone. I've got a long story to tell that I'll try and keep short. Coming out of the winter I decided to install a Jardine pipe, high flow air filter and change the oil on my '04 XB12S. I managed thru this job without any issues and burned an '04 race map via ECMspy. I did the...

    Has anyone disabled exhaust valve on stock XB12 exaust?

    @kiwilee: A couple of questions: 1) Did you do all of those changes at once? From what I've read the breather mod should have the biggest impact. I'd be really curious to know if there was any performance change with just the valve mod without the airbox/breather mods... 2) Besides the...

    Has anyone ever programmed Race ECM with stock exhaust??

    I'm about to do airbox, breather and DIY exhaust modifications and had a question. I'm going to do the airbox/breather mod first and I'll do the usual TPS reset and let it closed loop tune itself, but I got to wondering if anyone has ever programmed the Race ECM fuel injection map with the...

    Has anyone disabled exhaust valve on stock XB12 exaust?

    NativeXB - Great detail. Is all of that info in the service manual? I was under the wrong impression that the valve was closed at low RPM and then opened at high RPM and am surprised it's actuated at two different RPMs – interesting... As I mentioned in my first post , I was thinking the...

    Has anyone disabled exhaust valve on stock XB12 exaust?

    Thanks for the quick tips. I'm just starting to get a handle on the breadth of topics I need to consider and the breather routing is something I intend to look into. I fiddled with this a little last fall by taking the tank cover off (not exactly, I propped it up) to offer a more direct...

    Has anyone disabled exhaust valve on stock XB12 exaust?

    I bought a used '04 XB12S last summer and am in the process of figuring out what I want to do about the exhaust. The threads and tips on the website are incredibly helpful - especially since the supply of aftermarket Buell stuff seems to be getting slim with the shut-down of Buell (the only new...
