    Njloco, thnx for the tip! I have some BelRay & some Maxima Moto chain lube I use on my MX bike. I’ll look into using those.

    Cleaned all my grounds, found a stripped ground bolt that wasn’t tight as it could be, rethreaded a longer bolt in TIGHT after thorough sanding/cleans. Both sides of the battery grounds re-done.....and I’m not sure if this makes sense to y’all, but the ground wire from the battery terminal that...

    XB misfire at constant RPM cruising (~3500 RPM).

    Wow.... Yep, I’m in the same boat. I got my XB12S in ‘16...low miles (9k) ran rough. CE lights & stutters. I went thru several things and couldn’t figure out anything, kept plugging away at this and that. No improvement, got fed up & mothballed it for most of ‘17/‘18. Back to resurrecting this...

    Aaaannnd....the Earthing post I just read right below this was SUPER informative. Cleaning ALL grounds properly sounds like a MUST DO next

    Trying again- 2004 Buell XB12S, 9,000 miles. Runs, but hard to get idling, stutters around 2-3k rpm, periodically shuts off completely, and I have to turn off ignition and restart I had mothballed the XB for a while after not figuring out what was “off” with the bike. These gremlins had me...

    newb needs advice

    I had to download and try several drivers before I got close to getting ECMSpy to talk to my bike. Even then, I had to jump around to the different USB ports on my old laptop. Keep at it, you'll get the right combination of drivers & USB ports eventually. Another thing that helped me was...

    Thnx again! Found NRHS. It's in Berthoud, between Denver & Ft Collins. Nice to know they're there in case I can't figure this out! Actually it's on the way to Rocky Mountain Westy, where I get custom stuff for my VW Westfalia.

    Chickn, Hmmm...hadn't thought of that. It'd make sense given the worst of it happened after 10 miles or so. But then again, it ran fine a for a bit after the restart and I never really even stopped rolling. I'll do some reading into that temp issue. So far my "warm" days here, and the day I...

    "FNG" XB12 owner w/?'s

    Yeah, since I got CE light two or 3 times last ride, I'm hoping I got some stored codes. Hopefully I can check it with ECM spy today. My sched is pretty tight this week but I'll check codes & test those intake seals. Snow in the forecast again, that'll give me time to wrench. Funny thing...ya...

    Spring is sprunging (?) early here at 10,200 ft above sea level. Got past the ice rink driveway to dry open road and finally took er out for an open road ride. NOT SO GOOOOD! Heh heh.... Initially the XB12 rode much improved. New O2 sensor, Iridiums, TPS reset, Timing set & breather mod done...

    "FNG" XB12 owner w/?'s

    Ok, I've done the Timing per manual, new O2 sensor, new NGK iridiums, breather rerouted, TPS reset. Still getting stumbling/hesitation at 3k RPM. I can only run it up to temp in the garage, the roads are and will be buried in snow till March/April. So symptoms are under no load, gentle free...

    "FNG" XB12 owner w/?'s

    Thnx for the tips. I reckon your right about the PO. I've put the new O2 sensor in & got the TPS reset. Have all the breather reroute parts except the inline breather, which is ordered. New NGK plugs to put in. I figure I'll have time to finish these chores in the next few (altho life with a 1...

    Is this an acceptable method to set my timing back? I've seen other more thorough methods, but was wondering if this way looks ok to try? https://m.youtube.com/watch?v=YoHmh1JoT2U

    "FNG" XB12 owner w/?'s

    O2 sensor ordered, ecm cable shud arrive tomorrow & ECMspy (in English :-) running on laptop. Setting timing back to stock looks to be easy enough. Wonder if the weather will hold much longer up here? I reckon as soon as the bike is runnin right, it's gonna start dumping snow, haha JK!

    Sweet, Thanx for the tips. @Simply, yep, going thru the grounds and plugs/wires is a good idea and should be on my list for routine reasons. I suspect getting an eye on the plug color might possibly provide some answers. Air box mod is something else that needs looking into. Big thnx for...

    Hey all, First, thanx to everybody posting detailed and accurate info on these bikes. This forum is amazing. I've always wanted an XB and pulled the trigger on an '04 XB 12S with 9,100mi for $2k. The price was due to the bike not running right and I got the feeling the PO was just over it. One...
