I am having issues with my 1125. It has terrible throttle response when the engine gets fully warmed up and the intake air temps are 100 degrees or higher. I have turned the throttle grip 1/4 of a turn with no increase of rpm. I noticed this problem the first time when I rode the bike home from the dealer after they replaced the voltage regulator. I have been working lots of hours and do not ride the bike for pleasure often, so the problem did not appear very much this spring. Now the weather in Central Florida makes the intake air temps close to 100 upon starting the bike after it has been sitting in the sun a few hours. I took the bike to the dealer while it was acting up, got a tech to ride it and experience what I have been enjoying. He said the first step was a reflash. It took 3 hours to get the reflash done, I rode the bike and brought it back after a few minutes. They kept the bike until today (over 2 weeks) and told me it was good to go. I spoke with the tech, who said he rode it under the conditions we agreed the dangerous throttle problem happened under. I ask him what they found, they say it was the reflash, the first time they did it, it did not work properly. I got a ride to the dealer,take the bike and ride it back to work this morning. It began to display the same symptoms after a few miles of riding. Intake air temps 100+ and coolant temp in the 190 range. I called the delaer and informed them that the issue still exists, the said they will talk to the factory and get back to me about it. Has anyone else experienced anything similar? Thoughts..... | ||

I have the same problem. I didn't really start having it until about 1700 miles. By looking at the other threads I assume it is the spring that connects the throttle cable to the throttle bodies. Several people have removed the spring and seems that they have had some improvement. I figured I would give that a try this weekend and see if it works for me. | ||

Does this loss of power feel as tho you turn the throttle and nothing happens and when you turn it just a bit more it pops in and takes off liked a raped ape? | ||

Sounds like mine,but I don't have the reflash yet, and probably won't either...I disconnected the selenoid, and lubed the throttle body linkage and butterfly shafts and no more sticking! 100% better roll on and easier / smoother throttle control. | ||

Vincent, it feels a little like that while cruising. At idle it just does nothing until it finally begins to accelerate as if the throttle was just opened. I read the solenoid thread and that is what made me decide to post about this problem. I will try disconnecting the noid and lubing the throttle linkage. (I worked on it and am posting my findings now) I found the cable to the solenoid was holding the throttle blades part way closed with the engine off. I disconnected it and the throttle blades open correctly now. I tried to disconnect the solenoid, but I do not want to see the check engine light on, reconnected it. I left the clip on air box cover off, it sounds much throatier now. I have not ridden the bike yet, I will try to get it good and warm tomorrow and see if this helped.

Anytime you mess with the air-box base-plate, be very careful. If you don't get everything in the right place, the throttle can bind up. The throttle linkage is complex and can bind in several places. Put the bike in Diagnostic Mode and check for full range of 2% to 100% on the TPS as you go. It's worth the extra time and trouble.

Thanks Zac, I tested the travel mechanically, I will test it electrically now that you suggested it. | ||
| Vincent |
a good check to see if you are getting good travel is to get into the DIAG mode with the bike fully assembled and check the tps %. It should read from 2 all the way to 100%, if not something else is still binding. My solenoid was also causing my flies to only open 80%, disconnected from linkages and rolls all the way to 100. I have also noticed that while at speed, when you roll on the throttle it sometimes doesn't want to accelerate as well. The flies are sticking. Either they need to be lubed often or they have an issue with thermal expansion. Im hoping its just the lube but I suspect that its due to heat cause every time I have had this problem was when it was warmed up. Still trying to pinpoint it. I believe someone else had a similar problem as the flies sticking and I believe BMC just replaced the throttle bodies. | ||

well, the bike goes back to the dealer again tomorrow. This will be the third time for the same problem. if they don't fix it this time, the factory guys get to try one last time. I am pretty dissatisfied with this bike and the dealership that is doing the warranty work. I picked the bike up after they said it was fixed, that was the date of the first post in this thread. I waited a week and called them back, they made an appointment to test the bike again, a week after that. So in the mean time I am either not riding it, or risking an accident on a bike that is totally unpredictable and unsafe. | ||

silicone spray on the throttle mechanism after disconnecting the solenoid cable and removing it is what worked for me. go warm the bike up and inspect and lube again. tim | ||

I got the bike back today and was skeptical. They said it was the throttle cable, I rode it back to work and did not have an issue. On the ride home this afternoon the air temp got to 120 and the coolant 194. The throttle seemed to be responding as it should. Maybe they got it fixed. I noticed that the turn signal indicator was flashing really fast when I used the turn signals on the right side. The left flashed normal. It seems strange for a led to burn out with 1500 miles on the bike, but so far not much has been normal with this monster. I took the tail off tonight to look for a wire not connected. Everything seems to be connected, when I tested the signals tonight, the right rear signal is barely lighting. I guess I will take it back and have that replaced. At least the issues are becoming smaller. | ||

Both rear turn signal went south on mine. Broke them open. Found a bad LED in both. They have three in each side. I ordered, replaced both and didn't mess with the warranty. | ||

I rode it far enough today for the problem to rear its ugly head again. I took it back to the shop, they are going to call the factory on Monday. | ||

I had the identical issue with mine after the first service involving R&I of the inner airbox. It was the throttle binding, exacerbated by the solenoid linkage to the rear throttle body. A totally unacceptable condition. Problem was solved by rerouting the cable and adjusting the solenoid mounts. I have made this a non-issue for me by removing the solenoid apparatus completely and installing a noid eliminator. FWIW, take special care anytime you are removing the inner airbox assembly, as it is easy for binding to occur if anything is left even a little bit out of place. Jack | ||

Jp, your issue only showed up when the bike was hot? | ||
| Jpfive |
No, mine didn't need to warmup, it was constant. Your problem may be different, or perhaps my restriction was worse than yours. I suspect, though, that these binding issues are related to the solenoid in one way or another. Good luck on getting it fixed. Jack | ||

It is fixed. I got it back from the shop last week, but have been too busy to ride it far enough to be sure it was fixed. I rode it about 50 miles this afternoon, in traffic and out in the open, then back in traffic again. It runs great now. The throttle bodies were replaced, the bike runs better even at idle than it ever has. Now both rear turn signals are dead, but thats small potatoes |
