    Fast idle

    The shop manual calls for an idle speed range of 1,050-1,150RPM at normal operating temps. A cold idle speed will vary per circumstances, but an additional 200-800RPM is considered within the normal range. If you have an on-board voltmeter, you may notice the alternator isn't happy at lower idle speeds (charging rate at less than 12.8v) so some folks will adjust it to the upper acceptable range (1,150RPM @ normal op temp) to keep the charging system happy. That sort of adjustment seems to have no negative consequences. This can be helpful if you have additional current draw for any accessories. BTW, I've never personally seen a cold-start wax unit fail, but I suppose it's remotely possible.

    XX motor turns over but no start

    A new battery, huh? Did you bench charge it before installation? I don't mean with a trickle charger, but with a smart charger capable of at least 2.0A/hr. It typically takes 6-10 hours of bench charging at such low & slow rates to initially charge a 10AH battery (OE - YTZ12S/YUASA) to its full (and likely future ) capacity. If you didn't bench charge it first, remove the battery, check the cells electrolyte levels, and check the no-load charge level. Now let it sit for a few hours (if your garage is too cold, bring it inside and let it come to room temp). Now try bench charging with an appropriate charger. If you're using a smart charger you can let it charge overnight - it won't overcharge. Take a voltage reading after charging. As redxxrdr and superhawk996 said, a no-load reading of 12.7-13.5v usually means a happy battery. Per the shop manual, 12.3v or below indicates a battery beyond hope - replace it. Here are some helpful links . . . https://www.ronayers.com/oemparts/a/hon/506c2064f870023420a2f7ac/battery https://www.amazon.com/Yuasa-YUAM3RH2S-YTX12-BS-Battery/dp/B000WK4CS4/ref=sr_1_2?s=automotive&ie=UTF8&qid=1541266738&sr=1-2&keywords=2003+Honda+CBR1100XX+12v+battery+YTX12-BS https://www.amazon.com/Ampeak-Battery-Charger-Maintainer-Automatic/dp/B07DD8BJ9V/ref=sr_1_11?s=automotive&ie=UTF8&qid=1541266804&sr=1-11&keywords=12v+battery+charger+smart (not an endorsement - just cited as an example) It pays to do some research and comparison shopping. Best of luck!
  3. That's a sweet rider, with some nice accessories. If it's been as well maintained as it appears, the mileage (46.5K) isn't that much of an issue - as we well know. It looks like someone is gonna be very happy with this XX.
  4. Hmm, not original windshield, seat, or paint . . . missing decals alone would have me scrutinizing the plastic for originality. I suspect there may be more to the tale of this bike than as appears in the CL ad. Caveat emptor.

    Baked Bird or Bad Battery? Newbie question

    On my '99, the headlight didn't go out, but merely dimmed (clearly still drawing current) at starting. When I upgraded to HID (hi/lo) I added the switch - being illuminated helps, otherwise I'd likely forget more often than not to to switch the headlight on, like John mentioned.

    Baked Bird or Bad Battery? Newbie question

    I have a digital voltmeter connected to the battery (switched) and an illuminated headlight off/on switch (less load at starting - yeah, it does make a difference on my low mileage '99 XX). I've noticed that at near idle (1100rpm or so) the charging level stays in the 12v range, fluctuating slightly (12.5 - 12.8v). Add a hundred rpms or so, and it rises to 13v+, making the battery happy again. This is normal; the factory shop manual lists the idle speed as 1100rpm (plus or minus 50rpm), but that's just below the threshold to effectively charge the on-board battery.

    Garage door opener troubleshooting.,.

    I have two of the same chain-driven Sears/Craftsman 1/2HP openers (2 double doors, steel--yeah, they're heavy) that are original to the house (1992). I have similar issues with both (multiple button presses sometimes required, periodic short travel, etc.). I don't use remotes; so, activation is via interior (wall) buttons only. The problems seem to be exacerbated by extreme temperatures (for here that means below 45F and above 85F). At 26 years, I'm sure the openers' age plays a role. I replaced the nylon gears in both about ten years ago when it was apparent teeth were worn/slipping. My next move, when one of them finally gives up the ghost, is to probably replace both units.

    Is age an issue for Blackbirds?

    I wish I aged as gracefully as the '99 I have in my collection. Always garaged, soft covered, and only occasionally displayed at shows, where it consistently draws an appreciative crowd, it has accrued only 3K miles. Still close to original, all the rubber/seals/etc. appear to be in pristine condition. Unable to resist, I finally did tweak a few things (heli-bars, cruise control, HIDs, Dave's peg lowering kit, dark-smoke windscreen, digital voltmeter); but, I kept all the OEM parts. I've kept it titled/tagged/insured/ inspected per state law; but, I've not ridden it (or any of the other bikes in the collection) in some time. Clearly, I'm not aging as gracefully as I'd hoped. Oh, well . . .

    What are XX's worth in 2018?

    Here's a basic negotiation strategy . . . Price a set of new tires (installed - mounted/balanced), new chain & sprockets, battery, oil/fluids change, etc. (anything else it might need). Total everything up, deduct that amount from the asking price; that gives you a reasonable starting point. How you proceed to negotiate is up to you. Keep the pragmatic factors foremost in mind, rather than the subjective (or emotional ) elements. In other words, keep how badly you might want it close to your vest - believe me, among those of us who own XXs, we get it. Best of luck!

    What are XX's worth in 2018?

    That's very low mileage for an XX. Light drop on one side? Mostly stock? Not nearly enough info to make a judgment call. Tires? Fluids? Chain/sprockets? Ask all these questions and more . . . FWIW, the price could be in the ballpark for a decent rider (as opposed to a collectible example).

    Server error?

    Happened to me twice yesterday (18 Apr); today no problem. I'm using Linux (Ub-16.04). Refresh corrected it at my PC; but pretty sure it's a server hiccup.

    Pimp My Basement!

    In the first pic of the ceiling, there's a forced air HVAC vent (not a return) in the ductwork; so, can we assume the basement space is currently heated/cooled? Was that vent (and/or any others in the basement space) part of the original HVAC design? (The HVAC system would have been appropriately sized per code and subject to inspection.) If it is, then it may be all that's needed is to consider insulation for the walls and possibly the floor. If not (meaning that vent was an add-on, or afterthought), you could consider sealing it up, consequently not heating/cooling the basement space, and then consider an insulation application for the ceiling/first floor only.

    Pimp My Basement!

    Gotta basically agree with googus . . . Stud (16" o/c), insulate *, and sheet rock the walls; add a short-drop grid ceiling (w/lightweight foam panels) for future easy access. *If it's in the budget, look into closed foam spray insulation for the walls; it does an excellent sealing job and really helps with sound isolation/exclusion.

    John's Bike Bits

    Agreed . . . John has been first-rate, reliable and professional. His word is his bond; that still means something in this world.

    Time to say goodbye 99 BB

    That looks good . . . Hmmm, brass plate all the 5mm fairing mount screws and the cans--you'd have a steampunk XX . . . GLWS . . .
