    XB12S stalls only at idle, runs great

    Once you get your cable for ECMspy, go in there and take a pic/screen shot of both your front/rear fuel maps and post up. To do this, start up Spy, connect to your bike. Now you want to "fetch EEPROM". once it loads, go under 'map' tab, and you will see your fuel maps. there is a tab above...

    03 XB9S TPS reset problems

    Still check for intake leaks. Do the testing. I have a hunch your power cuts while cruising is ground related. Just find the loose one. After you get these fixed keep an eye on how she runs. If your power delivery is still sluggish keep an eye on your AFV. If it’s at 94% chances are during...

    Lots to do....need some advice....

    Not much comes out at once lol. But when you have a catch can and see it build up that’s when you’ll see it. You’d be surprised how much build up in a few days of riding. I bet it’s constantly dripping every few minutes of riding. I know it’s for epa crap, but still dumbfounded this was routed...

    03 XB9S TPS reset problems

    Nice. Glad you got it figured out. Check the grounds under your seat as their easy to check. I’ve had my battery cables rattle loose, as well as the ground to the left of the battery.

    I’d add a small catch can lol. Saves the clean up, and ensures none of the gunk finds its way near your rear tire while riding. Or at least plug it and just drain every few hundred miles.

    03 XB9S TPS reset problems

    So let me ask, are you able to see your tps value drop to zero in Spy? Or are you just backing it all the way out with no data at all? Well that’s def your starting point. Fix that and get your tps set properly. Are you able to check your AFV value? I’m curious what it’s at with your filter...

    Bro you’d be surprised haha. Mine looks like nut coming out when it fills my can. Some is liquid clear, but some of it is thicker whiteish creamy looking stuff. After seeing that, I’m GLAD I did that mod cause all that crap would be on your filter

    03 XB9S TPS reset problems

    Well first sort out your Spy issues and get it to read live data. Take care of your tps issue. Describe “okaying” and provide more details regarding “cut out when cruising in midrange”. Onc you get your bike to idle properly do the intake leak testing for leaks on your seals. I believe cold...

    I assume bike was running good prior? Or were their issues that made you perform the reset?

    03 XB9S TPS reset problems

    How did you perform the reset? Try again. Back out adjuster until tps reads zero. Snap throttle a few times to ensure it’s at zero. Hit the reset button. Now adjust to 5.5 or so. Readjust after temps reach about 180 or after a 10-15 min ride.

    Check your grounds. Make sure they are all secured tight. As mentioned above check your velocity stack on the bottom where it connects to the throttle body. Make sure it’s pushed all the way down and the clamp is on tight in the right spot. While you have the bottom intake plate off check your...

    Need a little tuning help please! Free Spirits exhaust this time

    I can help you make a conservative tune using your NB. Not nearly as effective as a WB as others have stated, but will def be better than what it sounds like you have. Make a log, reset your AFV to 100,record starting from a cold start, and ride around for about 20-30 mins. Go through the...

    You do not. those 4 are all that is necessary to remove the top, clean, and replace everything for your job.

    haha you may dude, as i dont know the correct terminology either haha. I believe you are correct though in the inner one being a intake though.. physcially makes sense LOL.

    replace 4 & 5 if you got it. dunno, this may be optional.

    Lots to do....need some advice....

    yes the outer is the "rocker gasket", but it also has a "inner" one. The intake gasket/seals are on the two ends of the throttle body (my second pic), and yes it is a separate job haha, not too bad though. If you didnt notice issues dont bother. in the diagram below, you are replacing the...

    It’s pretty straight forward on applying. Cool thing about this is it has the brush under the top when you unscrew it. I applied it liberally lol. Once you put a coat down you can tell this stuff will REALLY HELP prevent leaks.

    this is what it looks like with the top off. I already removed the outer in this pic an the inner still there. did or have you ever checked for leaks on your intake seals? Perfect time to replace them and cleaning your TB if you haven’t lol a lot easier with the motor down

    Lots to do....need some advice....

    Once you remove the rocker top with the 4 bolts the both inner and outer gasket is immediately in sight and can be removed. Make sure you get that rocker top and cleaned up and pretty and try and clean as much gunk off of the rear fins, fan area as possible. You want to clean as much of the oil...

    Buell xb9sx bucking/surging

    went to advanced auto, picked up the ford focus AC one, and cycled it through all the relays, with no luck. Then decided to remove the air box/plate and look for loose ends (few weeks back i dropped the engine to replace rear rocker), and still didnt see anything after checking plugs, wires...
