2007 UlY with 33,000 on the clock ran fine last fall over winter did fork seals, intake seals, new injectors and plugs. I took out this spring and when you get on the bike at about 4000RPM the bike just cuts out until you let off the throttle then its fine again till you get on it then the same thing happens. tried a different ECM, ran a ground from the battey to the grd wire on frame, plugged in my Buelltooth and changed the AFV to 100% it was at 85% before, changed the coils and a TPS reset all of these were done in stages trying to figure this problem out!! I am at a loss not sure witch way to go next.. Any help would be great

During fuel pressure test owner went for test ride and bike ran great. It end up being that he had disconnected the Iat (inlet air temperature sensor) anyway he installed a different Iat and fix the problem. Rare as it may be for a bad Iat if it is bad unplugging it might get you home or the nearest part store. Same Iat used on 90s ford F-150

On a ambient temperature the ET (engine temperature sensor) and the Iat (inlet air temperature sensor shouldn't be more than 10 deg temperature different between the two sensors. Use ECM droid or Ecm spy etc to do this test. Both sensors are thermisters which change resistance that changes voltage that is used by the ECM.

Did this problem ever get fixed?

I recently bought an ‘03 XB9R that has been modified considerably and raced, but is doing something very similar to what you describe.

Question: Do you need to pull in the clutch lever to start the bike even in neutral?
(I would appreciate responses from any XB owners to the question, as none of my 1125s require it)

Thanks Alan. I appreciate the response.
According to the service manual, this bike may have had a side stand switch, but the stand and the switch are both gone.
I’m wondering if the ECM relay ground is intermittent, considering that the ECM power relay, the side stand switch, and the clutch switch share a common ground.

Hopefully I can test ride it again tomorrow and see if pulling the clutch in brings it back to life during the “dead” time.

I may not get to it tomorrow...got a frustrating medical issue that needs some attention. Nothing serious, I hope.

One of those real PITA things.

FWIW, I’m making progress on my XB just by riding it with fresh fuel with a healthy dose of Seafoam fuel treatment added to it. There are a lot of “miracle in a can” products on the shelves, but Seafoam is one I’ve seen work, and trust.

I intend to run some new ground wires, and do a TPS reset if the programmable race ECM has that function included.
I don’t have the Harley Digital Diagnostic tool the manual tells you to use.
I suspect (but am not certain by any stretch of the imagination) those actions will smooth it out the rest of the way.

Get yourself a buelltooth at E-bay Etc. This can perform like like the factory tool. Plugs into your bikes data plug and can be operated by Druid base phone or tablet. We can give you instructions of it's use. ECM Droid uses a free app called ECM Droid. P.S pull that front plug what color is it.

Thanks Alan. I have a Buelltooth I bought from Dave a couple of years ago, along with a $50 Android tablet with ECMspy, or is it ECMdroid? (I think) loaded on it.

I didn’t know if it was compatible with the XB9R or not, but I do have a programmable ECM with the software to tune it. I’m told I can do a TPS sensor reset with that.

I removed the battery metal chassis using scotch bright I cleaned the aluminum chassis contact area and the metal chassis areas where both contact each other when mated together. I moved the grounds over to the metal chassis from the aluminum grounding point. I also used Alodine 1200 on the aluminum grounding points (this is used as a anti corrosive on aircraft also lowers electrical resistance on aircraft/rocket grounding points. Cleaned all other grounding points the same.Then coated a wax base Boeshield or LPS 3,my buddy who worked on the shuttle with me was a electrical technician .He said to use RTV instead of the wax base spray.Oops to late for me. Don't use any dielectric etc.. when assembling your grounding connection.RTV or spray wax base after assembly

Even if you don't have alodine it should be fine. Use white or green scotch Brite red has a metal in it that can induce corrosion. Emery cloth / sand paper with metal isn't good for cleaning aluminum and certain metals because of dissimilar metal corrosion.

Ironic...I got my A&P and PPL at Riddle in the late ‘80’s, and then decided to take a year off to work and save up a little money to pay for my advanced flight classes.

A friend had interviewed with a woman at the Cape who was allegedly in charge of hiring for the shuttle program.

I called her, told her my situation, that I had just completed 7 consecutive semesters at Riddle, and wanted to work for a year before finishing my degree program.
I had an excellent GPA, excellent references from all but one of my Maintenance instructors, and even had a letter from the president of the university, for having had the balls to interview him as part of an early Humanities class.

She refused to hire me.

I asked why?

She said in her experience, people who hadn’t finished their degree program never worked the length of time they promised to, and it wasn’t cost productive to train people who were typically leaving in 6 months or less.

Then I came down here at the invitation of my estranged wife, went out to dinner driving her car, with her and another couple we knew from the area.

We got rear-ended hard by an old couple in an 83 Buick Riviera...we were stopped at a left turn light, and he didn’t see the red light, didn’t see us, and tried to drive through us at 35-40 mph.

I happened to be leaning forward, tuning the radio and talking to my wife in the back seat when he hit us. Never did make it back to school...wish I had.

I had a three level lumbar fusion two years ago, and expect I’ll be having some work done to my cervical spine in the not too distant future.

I don’t have any alodine on hand, but I’m cleaning the ground areas with green scotchbrite, assembling the wires and hardware, and shooting Birchwood-Casey Sheath on and around the assembly with a small syringe. It should protect them for a while.
I have a jug of cosmoline somewhere...just can’t find it at the moment.

Yep. I had Mr Otis for turbines class, then worked for Dick Moore in the turbine lab while I did the Airframe portion of the curriculum.

I have a couple of stories about that time that I might add later.

I had Mr Titus for the piston engine lab and Mr Fish for the piston engine classroom portion.

Fish was always ragging on someone or something. Guess it helped make up for his personal inadequacies...

One day he pointed out to the motorcycle parking area, where my candy red metallic ‘85 FLHTC was always prominently on display, and made some smartass remark about “that stupid Harley Davidson out there”.

That bike was my sole means of transportation for several years, and I put a shitload of miles on it.

I wasn’t your average 18-19 year old fresh out of high school student. I didn’t go back to school until about 9 years after I got out of the Army.

When Fish made his comment, a few of my friends looked at me, expecting an explosion, but I just sat there gritting my teeth and digging my fingernails into the desk.

After class, I waited until everyone else was gone, and watched Fish nervously putter around with what appeared to be busy work for almost 20 minutes, then cornered him in the room, as far from the exit door as possible.

I walked up and asked if he was deliberately trying to get me kicked out of the class or what.

He stuttered and stammered, and finally got out that he didn’t know what I meant. (I was the only guy in the class that had long hair, a beard, and wore Harley T-shirts to class every day.
AND sat in the front row EVERY DAY.

I then asked if he was trying to get me kicked out of the class for assaulting an instructor.

I swear, he turned white, and I thought he was going to faint!
But he still insisted he didn’t know what I was talking about.,

Then I told him that was my Harley he had badmouthed in class, and I didn’t appreciate it.
All the while, I was moving closer, and crowding his personal space until by the end of this he was bending backward over a table to get away from me.

Did I mention I had locked the exit doors before I had approached him?

He eventually stammered out an apology, and gave another half-assed one in class the next day.

He was a lot more careful with his insults for the rest of the term.

I really wished I had gone to work at the Cape, especially after seeing a night shuttle launch from the VIP viewing area one night in the mid-to-late ‘90’s.

A neighbor in the residential air park I live in was a Pratt & Whitney engineer, who worked on the main engine boost pumps.

We were both on the community Board of Directors and had a meeting scheduled that evening, which we held in the car on the way to the Cape!

Mine is doing significantly better after putting some miles on it with fresh gas with a heavy dose of Seafoam, but still feels to me like it needs a TPS reset.

I tried downloading the software from IDS on Friday, but had problems doing it, and when I tried to start the adjustment, kept getting a “Port Not Open” message every time I attempted to access the module.

I need to get on the phone with IDS.

Well sheeit...I just did what I should have done as soon as I got it home.
I pulled the air box off, fired up the engine, and sprayed carb cleaner around the intake seals.

Spraying the front gave me a 1000-1500 rpm rise. Spraying the rear made no difference.

I think I’ll get the new 1125R running before I get in to rotating the motor for new intake seals and rocker box gaskets.

No need to rotate engine for seals. Can be removed from above and plenty of room for wrenching on the air scoops sides

I never did update on having to pull the clutch in to start it in neutral.
The previous owner told me he had a problem with getting the neutral light to come on when it was in neutral.
Either the ground was weak or the switch was sticky, because the problem has gone away.

Aside from the intake leak, my biggest complaint about the bike is the upturned end on the glass pack muffler.

When I crank hard on the throttle, wearing low shoes and no socks, my ankle gets roasted! Seriously roasted!

If or when your valve covers leaks it will be called a very slow seeping one. Usually the rear cylinder. I have 57000 miles on my bike. The rear cylinder gasket has been replaced. The front cooler running cylinder has original gasket. When you do the Throttle body intake seals reset the AFV to 100 if using the O2 sensor enable on ECMDroid. When using O2 sensor you will know if you got the seals in correctly when the bike goes into close loop.(close loop while idling means O2 is sending data to ECM as O2 heats up) the O2 sensor will correct fuel delivery as the engine heats up. You shouldn't have a rough idle at close loop. Allow about 10 minutes of idle will allow ECM to learn idle fuel curves.In open loop At start up the ECM will run the bike rich and begin to lean the fuel delivery as engine heats up and goes into close loop.I have mine set through ECM Droid to idle learn.

Alan, I’m told the bike has only around 5500 miles on it, but I imagine most of that has been on the track.

The front gasket seems tight, but the rear has some sort of sealant smeared around the outside of the mating surfaces.

I’m really not certain whether or not it’s currently leaking, but figured if I was going to rotate the motor for intake seals, I might as well do the gaskets.
Since I don’t have to rotate to do the seals, I’ll look more closely at the rear gasket before making a decision.

I’d like to get this bike trackworthy, and do some track days this fall. I already proved to myself I’m not ready to go full bore with an 1125, at least not without some training. This XB9 seems like a good place to start.

I think I would rotate and change that valve cover gasket if someone used RTV on the valve cover gasket trying to solve a leak.
