Sport Twin or Buell Cycle Center(the sponsors)can get you the Race ECM for around $190. It is the best mod you can do to a FI Buell for the money. It is easy to install it, it just plugs in but you do have to take it to your dealer after installing it to get the TPS reset. That should cost about $30-50 | ||

Sharkus, Wait until you're in the parking lot at the dealer to swap in the race ECM. Mine was unridable until I got the ECM reset. You're only looking at two bolts and two connectors. | ||
| Sharkus |
Should I not ride until I put the ECM on? Right now I don't have any midrange power and there is a good amount of popping and surging. Also the V&H sound is better than stock but I was expecting a little more growl and loudness. Is there a way I can get this without damaging the pipe? | ||
| Buelliedan |
If its popping and surging I wouldn't ride it until you get the Race ECM installed as that appears to be a sign of being way too lean. The V&H will get louder as the packing compresses. But I'll be honest, I am not a V&H fan. | ||
| Hootowl |
That's a tough call. How far are you from the dealer? Can you trailer it there or put it in a truck? | ||

I've always wondered, how is it the stock ECM could run "way too lean" with just the addition of a slip-on muffler? As far as I know the DDFI even with stock ECM monitors A/F via the O2 sensor voltage output and adjusts fuel input accordingly to meet predetermined values. Could it be the bike just needs to be ridden a few miles to allow the AFV to adjust to the new muffler? Of course a race ECM will certainly improve low and midrange performance. | ||

Anyone install a big bore kit without any head work? y2k01x1- 6.5" Marchesini You can not use the belt drive, it wont fit. | ||

I can trailer it to a Harley Dealership about 12 miles. Also one more question for you guys. I'm not sure if it's normal but there seems to be a lot of slapping, grinding and ticking inside the engine that I'm just not used to. This is my first V-twin besides a Honda Shadow. Should I be concerned? This was happening before and after I changed the oil. I used HD 20w-50 oil. I read on the X-files site that it could be a loose primary drive but don't know if that would cause this kind of noise. The bike only has 940 miles on it. | ||
| Buelliedan |
That depends on if your 500 mile service was done or not. The primary will be really loose if it hasn't been adjusted since new. Is it difficult to shift into neutral? As for other noises. The valvetrains on these Buells are very noisy and sound like rocks being ground up in a blender!! Blake, I rode my Buell with a V&H and no race ECM for almost a year. It didn't do the popping or surging like described above. But the Race ECM made a world of difference. | ||

Sharkus, Why not check the primary chain tension? If it's loose, adjust it to the high side of the specified tension (safety precaution, over-tightening is VERY bad). Make sure you find its tight spot before adjusting. I'm assuming of course that you have an owner's manual. The engine does however generate a cacophony of mechanical noise unattenuated by any water jacket. You mentioned a "Harley Dealership", you need a "Buell Dealership". A Harley only shop will not be able to help you. Good luck! | ||

Blake, Remember the movie Spinal Tap? Think of it this way: The stock ECM adjusts to 10 The race ECM goes to 11!  Sharkus, Yours is still breaking in! Doesn't hurt to check the chain, but the Sportster based engines that Buell uses are noisy, get used to it. Or wear ear plugs. | ||
| Sharkus |
Thanks fellas. I feel better knowing the noise is not unusual. There is a Buell dealership about another 20 miles further. I will take it there instead. I also have to get my owners manual before I adjust the tension on the primary chain...unless someone can give me some brief instructions. Again thanks, Bad Weather Bikers are the best. | ||
| Hootowl |
If you're not running in an RPM/throttle range that puts the ECM in closed loop mode, the O2 sensor input is ignored and it runs off the map. I don't know the exact values, but I believe the lower RPMs are always open loop. | ||

Blake: I got my telefix bars and I'm going to remove the top triple clamp; is there anything I should be concerned with in removing the bolt at the neck (ie bearings flying out, etc.)? I guess I want to know is it as straight-forward as it looks? Thanks. Gus | ||

Sharkus, That primary chain is almost definitely in need of adjustment. Two or three adjustments in the first 3000 miles is not unusual. After initial break in it doesn't require much attention. Chains stretch like mad when they're new. Buell valvetrains are somewhat noisy especially when hot. You will benefit from the race ecm and air filter. SteveH | ||

Hey José- I play guitar through a Soldano pre-amp. Soldanos actually go to 11! They're also priced accordingly. You could buy that thrashed RS on eBay for what some of the Soldanos go for. I don't get that... -Saro | ||

Is it just me or have you folks seen the nice write-up in the Oct. 2002 Cycle World re the XB9S? I may need to ride that bike... Jim in SB | ||
| Blake |
No, I've never seen the movie "Spinal Tap". I'm still wondering how just a slip-on can could foul up the stock EFI so badly when it is supposed to be able to compensate for varying conditions. I'm not arguing that it does, just wondering why. | ||
| Blake |
Jim, Heck yeah. Check the XB9S topic on the Quick Board. | ||
| Loki |
one line from that article says it all.... -Buell said he instructed the design team that he didn't want the new Lightning "to have any tail. I wanted this bike to be more S1 than the S1." Loki I see it coming now, the XB9RS. Someone will do it, take the 9R and put the S tail on it. Talk about a track day special. | ||

I'd ride the thing to the dealer, see of the AFV is out of whack. Get the Race ECM. Blake I have often thought the same thing, how can the black boxes be that different. This is a "smart" system that corrects for lean/rich situations based on sensor feedback. DDFI closed loop mode 2500+ RPM under load. I'll bet it will sort itself out as well as it can with the standard ECM, but do get the Race ECM and a good air filter. What mapping does your 1999 ECM have? Several were in use each updated by another at one, hopefully you have the latest mapping. Let us know what the sticker on you ECM says. Jeff | ||

Blake, Under 3500rpm, and at WOT the ECM takes no readings from sensors and instead relies on maps, way too lean maps in the case of the stock unit. This is "open loop." Rob | ||

Looking for a bit of assistance on X1 Front wheel spacers - There is a short one and a long one. According to the parts book the short one goes on the Left side (sitting on the bike I assume) and is PN 41129-99Y, the longer one is on the Right and is PN 41128-94Y (disc side). I ordered what I believed was the shorter one but I received the longer spacer in a bag labeled SPACER, FRONT AXLE, LEFT 41129-99Y. Was the wrong part in the correctly labeled bag, or is the book wrong, or am I just confused, or ? I had to wait 1.5 weeks for this to come in and am now afraid to order the wrong part again. Thanks in advance for the help | ||

O.K. I buy a ASB shock wrench for the recall shock on my 97 S3....BUT.....that shock blows up...so....I get the recalled, recall shock...AND...the $30 wrench doesn't fit. SO....does anyone know what size wrench (in inches) fits the new shock?? TIA Steve | ||
