I've searched the KV and can't seem to find exactly what I'm looking for. '03 XB9S with race kit. I installed the kit and had the TPS reset. I don't think they knew WTF they were doing, seriously. Top gear, cruising at 65, whack throttle WFO and it's like the motor hits a wall, little or no acceleration. If I let of on the throttle a smidge, she picks right up. I had the same "tech" that did the work on it take it for a spin. He says, "ya just need to downshift". Uhhh, yeah. I'm 99% sure it just needs a proper TPS reset. I'll find another dealer. Everything was installed correctly as far as the race kit goes. Thanks guys! | ||

definitely sounds like the TPS to me. | ||

yeah, me too, didn't do it prior to "techless tech" f'n with it. Anyone in Mpls/St.Paul area got the gizmo to do it? Will provide free wheelie entertainment after it's done. LOL | ||

Do you have the newer,XB12,05 XB9 inner airbox lid? It helps take some of the midrange dip out of the powerband. | ||

I experienced the exact condition you described. I spent quite a bit of time last summer tracking down the problem, testing sensors, testing the condition in all gears (which it would do just not as long), and just a large amount of thinking and research etc.. I came to the conclusion that for some unknown reason when I would instantly open the throttle to the full open position, that there was some type of inlet air restriction. I had cut the snorkel only part way, to keep intake noise down (and other reasons, because I theorize too much at times). Well, over the winter (more theorizing) I removed the snorkel completely, and cut it that it would just create a seal between the air box cover and the frame, so now there would be no restriction in that area. I then started to think about the new ’06 air box assembly, then just by chance a fellow BadWebber was selling an ’06 outer air box cover, so I purchased it, and since I already have an inner ‘04 air box cover, I cut the side out similar to the ‘06 models. I have been out 3 times this year at 4 to 5 hours riding each time, with the new setup and, so far, with positive results. The problem has not reoccurred. Now, I did ride the bike for 20 min above 3000 rpm to let the ECM adjust to the current air conditions (driving down the highway) before trying to make the condition occur. Daily temp was between 65° to 75° with relative humidity around 60%. Another observation was with the ’06 outer air box cover, the heat I would normally feel on my right leg was not apparent as with the 03’ outer air box cover. This is just my experience; others may have experienced something different. Drivability issues are usually the most annoying and difficult to resolve, hopefully this provides you with some insight and I am sure if you decide to try this setup Daves will be able to supply the parts.

had the same problem last year. had a tps reset done and the tech gave the bike right back before testing/running it. ran like poop! i brought it back and had the tech check it. told me it was due to my "un stock" set-up.  i got a different tech to check it and he just ran it at like 3200rpm for a few minutes so computer would re-learn new settings. all was good after that. i love how when things don't work after they mess w/ it it becomes "my fault" for putting custom pieces on. ran fine for months before i brought it to them. how is one supposed to argue w/ the tech on this? simple say  and learn to work on your own bike. i also had my warrenty cancelled that day due to an aftermarket exhaust and the f.a.s.t. system. god i love harley stealerships (mine anyways) | ||

Firebolteric- Dude, no one can cancel your warranty for installing aftermarket parts, they can ONLY choose not to cover the parts of your bike affected by the mods you made. Example- your headlights stop working after you did engine intake mods, they still have to fix it. SEMA, the Specialty Equipment Manufacturers Association is a huge group, and they fight hard for the aftermarket companies. They lobby politicians, etc., because if aftermarket parts voided entire warranties, the aftermarket companies would go out of business. SEMA has made it so that the law states that it has to shown that your mods caused the failure for that part of a warranty to not be honored. The dealers just love that this myth is widely believed- that you "void your warranty" by modifying your bike. Sherm | ||

my 06 cityx was doing the same thing. felt like it was bogging down so i let off a little and then got back on it...i have not reset my tps. It would also act real funny a lower speeds in a tall gear as well. It DIDNT do this with the factory ecm so i swapped the stock unit back in and am waiting to get the software in to do the tps reset myself with the race unit. I have also spoken with a few people in the industry today and they have informed me that there are service bulletines that come out for the HD tech recently on properly resetting the TPS. It seems from all the mass chaos that nobody is reading them. I refuse to go back to the dealership unless I absolutely have too. Some kid in the parts dept. also tried to tell me that it would void my warranty.....I laughed at him and said...ahhh OK whatever go away now | ||

My 9 has run horribly, then was corrected after running on the highway at 3200 for 10 minutes or so. It kind of sucks, because you can't run with traffic and keep the RPM steady at the same time, seems dangerous. But it has worked for me before, straightened the bike right out. |
