If anyone remembers I was having an issue with excessive noise from my 1125R. It turned out to that the teeth on the counter balance gears were shot. I took it to the dealer and they took care of it. Now that I have the bike back and have had a chance to ride it a bit the bike seems completely different, at least as far as the motor is concerned. It runs much quieter now which is a good thing of course. It also seems to run much smoother which itself is a good thing but it also is down on power as far as I can tell. I would describe the power delivery as soft. Blipping the throttle on down shifts isn't the same and also feels very soft or lazy if you will. In 1st if I crack the throttle it won't pull the front tire until the RPM gets to about 8000. My thought is that maybe they re-flashed the ECM to a newer version. When I connected to the ECM with ECMspy it said the revision is BUEZD0P0 12-17-08. I searched and found that the latest version is M3HUS062 but I couldn't find how ECM spy would call out the latest version. My 1125R is a 2008. Any input on what the issue could be is appreciated. Thanks, B | ||

You've definitely got an older flash on it. The date should be either 9-30-09 or 11-30-09 from ecmspy I think. | ||

Also try reseting the TPS. | ||
| Vinix |
Did they comment on seeing this as a common issue or an isolated issue regarding your gears? | ||
| Boogiman1981 |
yeah there have been a few updates since that flash i got the newest one a few weeks back and WOW was using that same one you have now. | ||
| Bueller4ever |
Check in diagnostic mode that the throttle is opening fully. | ||

Vinix, They didn't say and I didn't ask. I'm guessing if it is common HD wouldn't want them saying anything about it. I'll see if they will update my flash and see if that helps. I have a question for you guys. I have ECMspy and a cable. I know the tables are incorrect so I cannot use it for tunning but I am wondering if I can pull the data from another bike and write it to mine with what I have. I'm guessing I can but I'd like to be sure before I try it. B | ||

I would think that you could manually transcribe each table value for both fuel maps and both spark maps using ecm read and tuner pro. I have a 2008r with the latest flash and ecm read named the file "BUE2D242 11-30-09" with an additional date/time stamp appended to that (when I created the backup). I have excel copies of the 4 tables mentioned above if you need them, but it would probably be easier to have the dealer burn the latest for you. | ||

What I was hoping I could do is just do a "fetch" of the EEPROM from another bike and then down load that to mine with ECMspy. I know I can do that but I'm not sure if because ECMspy doesn't support the 2008 and newer ECM's if it would transfer all of the data. I'm guessing it will but I'm only guessing. The only reason I'd go the ECMspy route is because the bike I'd take it from runs just as my bike did before it was serviced. I'm thinking though that flash isn't the problem because if the dealer had flashed it the version would be newer. I may have them put in the latest though just to try it. B | ||

Bloose - that would work as long as it came from the same firmware (buezd for you). I have bue2d so you would have to use tunnerpro as an intermediate step. | ||
| Ysracer |
I would also reconsider whether the disintegrating gears may have damaged the engine. Mine is getting really noisy, too. I have a oil sample out for analysis and am going to peek under the cover tomorrow. | ||
| Bloose |
I don't think physical damage is the problem because the power loss seems to correlate with the repair. Unless they damaged something while replacing the gears. I think them damaging something is very unlikely as the repair shouldn't have been very intrusive. I took it to the dealer today and they could find no problem and they flashed the ECM with the latest update (I have not checked it). It still runs the same. It essentially feels like there is an extra 50lbs in the front of the bike. I cannot pull the front end up in 1st gear with throttle only no matter what. Before all of this pulling the front tire in first took nothing more than rolling on the throttle. I'll have to call them again on Monday. Another issue, which I'm sure is directly related, is that since getting the bike back it occasionally will not start. No matter how long you crank it will not fire up. You may get a pop here and there but it won't start. Then if you release the starter button and press it again it fires right up. It actually did it today when I started it to take it to the dealer. Unfortunately it doesn't do it all the time. I told them about it but they didn't seem to think much about it. B | ||

Ysracer, My oil sample came back with 0 metal content even though the gears were shot. This is likely because the fragments were either picked up be the magnet or the filter. I think an inspection of the filter and the drain plug is really the best way to investigate. B (Message edited by bloose on May 21, 2010) | ||

If I was in your position I'd be looking for another dealer. Sounds like they screwed something up and aren't sharp enough to know they did it wrong. | ||
| Bloose |
I'll cut them lots of slack because a) they were sharp enough to identify the original problem b) they are helpful and courteous c) this problem is likely not obvious so not easy to find d) most importantly they are the only dealer I've been to that even gives a damn. I'd rather go to a dealer that is giving it their best effort and coming up empty than one who could care less. When Buell was going strong most dealers I'd been to were down right crappy on the Buell front. Now that HD shut them down I'm sure the crappy ones are worse. This dealer still cares so until that changes I'll keep working with them. I won't lie and say it's not frustrating to have a dealer tell me nothing is wrong when I know something is, but at least I know it's not because they don't care. If I come up with the answer I'll be sure to post it here. Any other suggestions on what to look for? B | ||

Check and make sure the throttle plates are opening fully | ||
| Bloose |
Bueller4ever and Therealassmikeg, You guys hit the nail on the head. When I took the air filter out I looked at the butterflies with the throttle rotated to max open. The butterflies were only about 60% open. I then took the entire air box assembly off and presto, 100% open. I couldn't figure out at first why when the air box lower plate was on why I'd only get 60% throttle opening. I found that there was a linkage on the right side that was binding somehow when the lower air box plate was installed. After a while I figured out that when the dealer reassembled the air box they didn't install the lower plate to throttle body seal correctly. What they did was just plop the plate on top of the throttle body seal which in turn pushed it down and onto the linkage. Once I figured that out and installed the seal properly it solved the problem. The great part is the bike is back to normal; actually it seems even better than before. Thanks for the suggestion! I'll be calling the dealer tomorrow. B (Message edited by bloose on May 23, 2010) | ||

Bueller4ever & Therealassmikeg - nice call. (Message edited by dannybuell on May 23, 2010) | ||

This issue was very interesting. I am glad you got it sorted Bloose. I just checked my butterflies today and all is good with mine. I will have the counter balance gears checked on mine at 13000 while they check the valves, bearings and forks. | ||
| Mountainstorm |
Good work Bloose. Like old whathisname likes to say: HD, making mechanics out of Buell owners since 1983. | ||
| Bueller4ever |
These air boxes are to complicated for some dealers. They also fail to pull the IAC hose far enough up through the lower air box plate, which will rub on the throttle linkage. | ||
| Mountainstorm |
Is that what that hose is. Ah ha. | ||
| Bloose |
Yes, that hose was originally what I thought was the problem. It did look as though it may have been rubbing. I took a lot of time making sure that wasn't the problem and then for a bit I was baffled. The whole time I kept thinking that I thought the lower plate was harder to remove the first time I did it. Then it occurred to me that the had assembled it wrong. B | ||
| Bobbuell1961 |
It's easy for a lot of techs to make this mistake working on bikes with 300+ lbs more and close too a 100 HP less, Runs normal. LOL. Bob  | ||
| Therealassmikeg |
lol...I did it to my own bike and have never touched a harley...got any job openings for me there Bob??? Glad you got it sorted Bloose | ||
| Dktechguy112 |
can you post up a pic of what you guys are talking about? my butterflies are not opening fully, and i think i may have the same problem. | ||
| Randy_bowers |
Had a sim prob with my 08 but it turned out to be the wireing harness was interfiring with the linkege. Alls well. | ||
| Firemanjim |
Very tight fit on that side,have had both the wiring harness and the seal fit cause exactly that on the 1125's here at shop. | ||

I think an inspection of the filter and the drain plug is really the best way to investigate. B Bloose - Glad to hear you found the problem and it wasn't serious. I just got the results of my oil analysis back with this comment: "Aluminum appears high. This shows piston/cylinder type wear. Check the engine for excessive crankcase pressure. Check for oil consumption. Change oil and filter and re-sample in a short period. NOTE: The total engine mileage is not known; if this is a new engine these readings could be from break-in wear." Aluminum is 28 (ppm ?) Iron is 27 Silicon is 15 Lead is 5 Copper is 3 Particle count per 1mL is 0 for all sizes. I had ~ 1300 miles including two track days when the sample was taken. Maybe it's still breaking in ? I suppose I'll have another analysis done to confirm. | ||

Do a leakdown test...if it is ok...run it.. |
