I just put in a new (used) throttle body and new James Intake seals. Did the TPS procedure, but the bike will not idle. It will start up, idle very high for a second then dipping below 1k, then coughing a few times before cutting out. A bit of smoke floating up from the intake. Any ideas? It's a 2007 Uly. | ||

you might try holding the throttle open a little just to keep it running for a few minutes...then try going for a ride...mine sometimes takes a little while to learn whats going on and smooth out | ||

I hold the throttle open, but after a second or so, it seems to lose fuel and drop down again. | ||

I made a new thread in the troubleshooting section. | ||
| Djohnk |
I couldn't find your new thread ... Take it for a ride, that exact same thing happened to me when I installed James gaskets on my '07 Uly a month ago. It settled in nicely after a 20 minute ride ... don't know why (you might take a allen wrench with you also to adjust the idle after about 10 minutes riding). I didn't realize how bad the intake seals were leaking until I put on the new ones, its like I have a brand new bike now. Let us know if it worked for you also. Here's a pic of mine installed: | ||

The bike would not idle for more than 2 seconds. To keep it alive, I had to keep the throttle nearly pinned at 3k+ I've taken the Tbody off. Gonna try again next weekend. I will be a bit more "even" when I tighten down the bolts to the cylinder heads. | ||

May be that one of the seals didn't seat right. Could be from large vacuum leak. | ||

Make sure you have enough gap between the TB and the head for the lip of the new seals to fit. I had to file a little off the TB to make room for the James seals. You shouldn't have to jam the TB in to line up the bolts. Also, lubricate the seal on all surfaces and even lube the part of the flanges that touch the seals. As you pull the flanges down evenly they need to slide over the seal to maintain even pressure. I use Dow Corning 111 or 112. Hylomar is good or any non hardening silicone lubricant. As you tighten the flanges keep an eye on the gap between the flange and the TB. Try to keep this gap even as you tighten each screw a little at a time. In Djohnk's photo you can see how even the gaps are. That looks good. | ||

I remember something I that might be important... there is a front and a rear cylinder flange (marked with "R" or "F" I think). I don't think its good if you mix them up, but I don't know for sure. Also, I just used a thin layer of petroleum jelly on the gaskets. | ||
| Tootal |
Yes they are different as the holes are about an 1/8" off center. Why you would do that is beyond me. They are not only off center but are different distances from the center. I guess that's where the meat was on the head so they put them there?  | ||
| Etennuly |
The petroleum jelly will work fine, that is what I used. The front to rear mix up.....well....  If that is the problem at least you have a fix that is not a real big deal. | ||
| Rayycc1 |
where exactly are the front/rear markings on the flanges? I can't remember seeing them when i put my new seals in and my bike has not run right since....this could very well be my issue as well | ||
| Firemanjim |
Stamped right into flanges, and pretty sure you cannot swap them. | ||
| Rayycc1 |
cant as in they will not bolt on?....or as in it wont run right if you do? | ||

Update I've reinstalled the tbody and seals, and this time I used a lot of petroleum jelly. I've followed the TPS reset by the book. It will start up a bit better than before, idle at about 1200 rpm, then die after about 5 or 6 seconds. If I try to keep it alive with the throttle, it feels like I'm choking it out. If I try to keep the throttle steady at 3k rpm for example, the rpm will climb, then fall over and over again until the engine dies. It's as if the power is pulsing. Perhaps a faulty fuel pump? Sometimes it takes a little longer than usual for the engine to start up, and it might backfire. This is probably a longshot, but if there's anyone in the Hampton Roads, VA area that could lend some help that'd be amazing.

A couple of years ago I did winter maint on my bike and stuffed a rag in the intake while thing were apart. Several weeks later, I hastily reassembled, and forgot the rag. I mention this because your symptoms remind me of what my bike did when the rag got sucked into the intake. | ||

I had a paper towel go through my son's ULY engine and out the muffler but some of it was still stuck in the butterfly valve slightly holding it open. The interactive exhaust valve was going nuts while this was all happening and the engine was going as crazy as the exhaust valve. I even took it out for a ride while this was happening and was lucky it didn't cause a wreck. I then took off the air filter cover and saw the piece of paper towel stuck under the butterfly valve and removed it. Did a TPS reset and then it ran like a top and has ever since. The paper towel was left because I was rushing the job after a engine rotation button up. Glad it wasn't a cloth towel. There was burnt paper on the garage floor where it had blown out the muffler. Felt stupid. | ||

I still say take it for a ride ... mine ran like crap just like yours after the TB gasket change and TPS reset. I totally expected to be restarting it several times when I took off out my garage. I was pleasantly surprised ... it settled down after about 5 minutes of riding. | ||
| Deeds |
I took a video of what's going on. The first two starts, I didn't touch the throttle. On the 3rd start, I kept the throttle cracked. https://www.dropbox.com/s/b8ewuxer4lnjpm0/2014-11- 15%2019.08.06.mp4?dl=0 | ||

Kinda an odd thought, but have you checked the timing??? Mine acted similar a while back and turns out the mark was a bit forward of center. Seeing as the ecm controls timing there is no need for it to be advanced. | ||

Injector seals will leak air also,I changed mine out the were very brittle. | ||
| Johnshore |
It sounds like it runs well till it runs out of fuel. I have no idea what it is because I'm no mechanic but I would look at the fuel line or fuel pump. | ||
| Rayycc1 |
i had a problem similar ...inside the tank...when you pull the fuel pump assembly...there are two rubber bushings that hold the fuel filter onto the mounting plate and the regulator...those rubber bushings got brittle and cracked on my 06 allowing the fuel to pump right back into the tank...the pump sounded fine...and was actually working fine...but not enough fuel was making it to the injectors. It might be worth pulling the pump and taking a look. There is no need to remove the swing arm...you can pull the pump in 15 minutes just y removing the rider peg bracket...and the bottom shock bolt...raise the bike and this will allow the swing arm to drop JUST enough to get the pump out. You will need new o rings ...or you can reuse the old ones if you leave them dry out a week or so then lube them. HD does not sell the above mentioned bushings...i used 2 pieces of fuel line and sanded them down to fit snug. Not saying this is for sure the problem...but if it happened to mine...it could happen to another one. Same exact symptoms. easy but a little time consuming fix. | ||

Man if you figure this out let me know. Mine is doing something very similar sometimes. Other times it runs great. I am going to change out the intake seals and TPS sensor next. If that doesn't work I will take out the EBR ecm and go back to stock. | ||
| Tootal |
If you have an old analog voltage meter you can hook it up to the TPS sensor and rotate the sensor. You should get a nice smooth sweep of the needle. If it stutters or drops off anywhere it has a bad spot and will need to be replace. | ||
| Nobuell |
Deeds What problem did you have prior to changing the intake seals? Also what year is the bike? (Message edited by Nobuell on November 17, 2014) | ||

There was a sound of "crackling" near the intake when pinning the throttle that I could only guess was air being sucked in where it shouldn't, and the rpm would slightly hang on decel. The seals also failed the leak test. Considering those issues, I copped a used '06 throttle body as well as new James seals. The bike is a '07. | ||
| Tootal |
Did you tps sensor fit the 06 throttle body? I think the late model 06's had converted already to the 07 sensor but not all that many. Maybe you got lucky or maybe that's the problem? Did your tps sensor have an orange dot on it? | ||
| Deeds |
Update! Made a bit of progress tonight. I put the old TPS on the tbody. They're both the new revision with the orange dots. Did the TPS reset by the book. I can get the bike to hold an idle for a few minutes. The idle surges quite a bit, between 700-1150. I haven't been able to set the idle after getting to operating temperature because the idle is surging so much. There's a pop here and there at the intake, as well as the exhaust. After a few minutes, it will sputter and die. Here's another video. https://www.dropbox.com/s/mw9o1hsxm486o7d/2014-11- 18%2023.08.11.mp4?dl=0 | ||

Are you looking with ECM-Spy, if so what is AFV and what is TP percentage? Have you tested the new seals by spraying Brakleen or some such as bike is running? |
