Just got my 2004 XB12S last week. They delivered it with 330 miles on the odometer and it wouldn't even idle. Sent it back for service and all they did was raise the idle to about 1100. Sounds and feels like its running lean. And the cooling fan will run even if I'm cruising the Interstate at 70. Any suggestions? | ||

Sorry to hear that, not a good first impression. I had idle issue until my first service, unsure of what they did. After the racekit ECM was installed I never had another idling problem. H-D/Buell is supposed to set the bike up for you before it goes out the door. Does anyone know what is required with the initial bike setup? | ||

Welcome to the madhouse! Give some more info. Is it stock? Race ecm? Race kit? How is the on/off throttle response? Does it run smooth at 2500 rpm? At other rpms? For now I'd say have them reset the tps/afv according to the service manual. Also note that the bike isn't broken in yet, so the fan does come on more often. This will get less after 2500-3000 miles and you change oil to synth. If it was a demo, then I would asume the bike wasn't broken in properly and "abused" by testriders. I'd change the oil and put regular dyno in (if that's not already in there) for the next 2000 miles or so. Then change to synth. During the break in of my xb9r the fan would come on on the interstate in the winter (~10 celcius) when doing a steady 120 kmh (75 mph). Btw, Idle should be set between 1000-1100 rpm. Personally I'm convinced idling AT 1100 is too high. | ||

I believe that the idle should be at 1100 rpm. My 9r says so on a sticker on the left side of the frame under the triple clamp with the emissions info. Mine came from the dealer with a 750 rpm idle and it was crap. So I adjusted it up. | ||

The bike will run hotter than 'normal' until it is well and truly broken in. More wear as the engine breaks in = more heat. As for the idle, what do you mean, 'wouldn't idle'? It would stall out? The idle should be set to 1050 (for an XB9, not sure about the 12s). Any higher and it will cause the infamous 'idle hang' when you stop. Does their bill of sale/title indicate a mileage other than 330? If so, perhaps you can do something about it, although having already taken it home that's doubtful. | ||

I think the manual states 950-1050 as the proper idle. I don't think I would assume that it was broken in improperly exactly, but a possibility. It sounds to me like maybe they used the old scanalyzer to reset the TPS instead of the newer Digital Technician. The Scanalyzer is good for an '03 9 but from what I've heard it won't reset the 12's properly. | ||

To clarify myself, I am not implying that the idle problem is due to improper break in. That could be the tps. I mentioned the break in because it not yet fully broken in and runs hot (which is normal during break in). | ||

Dealers dont let testers break-in demos. The dealers put the break-in mileage on. Course thats not to say testers dont abuse demos. (Message edited by ted on November 04, 2004) | ||

have seen sales persons start new bikes on floor, and repeatedly cranking the throttle on brand new, cold engines, revving them senselessly the efi system on the XB series does not respond well to throttle blipping on a cold engine. the result of useless throttle turning on a running, but cold xb engine is to foul the O2 sensor, and then shifts the AFV and thus overly enrich the mixture, making bike hard to start, run poorly, foul plugs. this condition can be cured by taking the bike out for a spirited romp of at least 15 or 20 miles, get it good and hot, this will clean up the plugs, O2 sensor, and bring the AFV value back in line to your current ambient conditions. once you have it running right, keep teenagers, brothers in law, and people fond of jerking off their carbureted harley noisemakers AWAY FROM YOUR XB. also keep your idle speed set between 1050 and 1150, depending on the season, and your ambient temperatures. high end of range here in alaska in fall or spring, you guys in arizona, or S cali seem to do better at lower speed. | ||

Dealers dont let testers break-in demos. The dealers put the break-in mileage on. I got a demo bike with 1 mile on the counter. I figured that was from pushing the bike in and out the showroom. They *told* me several times they should do the break in. Only saw that happen with an xb12r. Even that bike got sold with 300 kays on the counter. Not fully broken in. I know what they *should* do, it just doesn't happen most of the time. | ||

M1, My manual says 1050-1150 rpm. | ||

That's probably it then... my bad. I've got mine at about 975 (or just under an indicated 1000 anyway) and it seems to be fine. It stumbles every once in a while on a real cold morning but that's OK with me. | ||

I was given a demo XB with eight miles on the odo. |
