So I was stuck behind cars on Mount Palomar. I am spinning at 3000 to 4000 rpm. All of a sudden she tries to die. When I come to a stop she won't idle. I have to keep giving her gas or she dies. This even happens while going down the road. At 5000 rpm it feels like I hit the rev limiter. I was getting bad lean surge after the bike started to act up. Once home I try and start her and she idles to 3000 rpm and dies. Sometimes she will surge for a short time and die. I make it home.

The XB12r is a 07 with 14000 miles. I have a D&D exhaust, and a K&N air filter. I have played with the maps. She was running real good on the latest map I made. I put the stock map in and the same symptoms. I changed the plugs and the were black and wet. Too rich I assume. I opened up the air box and it was all oily inside. I had cleaned the intake 1500 miles ago and it was black and oily. I decide it was time for the breather reroute. I cleaned out the whole thing with seafoam. I did multiple TPS resets. I tested the TPS. All seems ok.

I have had a few backfires and even one through the throttle body. She just won't run with out me twisting the throttle. She falls flat on her face. I open the butter fly on the throttle body and I see black oily mess in the front cylinder. The rear one is cleaner. I see carbonized black oily mess on what little I can see in the throttle body on the front jug. Both cylinders seems to fire. I ordered plug wires and a coil. I might put new intake seals on the throttle body.

Any clue? I have read multiple near exact issues but no fixes to the problem.

I put new plugs in when it cooled down. I also did the reroute of the breather bs. I rebuilt the fuel pump 3000 miles ago. It had chaffed wires. I put a fuel line around the wires and put it back together. It has been fine since. I will have to check the regulator and cam position sensor.

Pop open the airbox and have a look at the throttle body/butterfly/shaft.
Your symptoms sound like what my X1 did when the little shaft broke.
The TPS sensor is on one side and was basically not moving when I poked at the throttle.

Someone found a cross reference for the TPS so you can buy it at the auto stores, have to search to find it.

Always start at the battery, make sure it is good and fully charged.
Then check the battery cable connections, especially the ground cable connection to the frame.

on the 2003 in northern areas, you might also need to remove and clean the subframe. I just ended up running a second ground wire from the frame lug to the engine mount on the engine side to try and sort out a starter motor issue. I may run another directly down to the starter once I find a spot to attach the wire.

The shaft is ok. I twisted the throttle with an ohm meter attached to the tps. It changed states evenly, .5 to 5.00 ohms or something like that. I did buy the tps213 at autozone. It was not the right tps. The range was wrong. When installed it would not allow my throttle to open fully.

I have started it with the air box off and I get detenation up thru the throttle body. I am getting a back fire thru the throttle body when I give it any gas. I am also getting gas in the exhaust as well. I seem to be getting lots of gas in both the intake manifolds and out to the exhaust. I might have a intake manifold leak.

I put mine under the nut on one of the through bolts, right hand side about three years ago. Come to think of it, I haven't had to clean subframe, etc connections since. It was an easy access job and the wire was simple to route also.

Have you checked the static timing? Just wondering if the plate has moved or if maybe the sensor is going bad.

Rubber plug on the side of the tbi unit went bsd on mine and a fellow webber, replaced that and all was well.

So i found the front cylinder intake seal was bad. It now will idle but there is still a problem. I am leaning toward the cam position sensor. For some reason the cam position sensor diagnostic check box was unchecked in the ecm. It was at the dealer before I bought it so I think they were chasing dragons trying to find a problem. I am only guessing.

I know this sounds funny but check your plug wires I had a mouse chew into mine and it wouldn't fail until it got hot or wet played hell trying to figure it out.

Looks like it might be a bad cylinder temp sensor. I disconnected it and the bike ran for some time before dieing. It would not do that with it connected. I also changed the cam position sensor it started coding.

I changed out the head temp sensor it was bad and out of range. I next pulled the fuel pump and found a bad hose. This kept me from full pressure. Still it ran like dodo. I next set the AFV to 100% Tada. The beast is back.
