Quick list about the bike.

2008 7000 miles
All stock when I bought it, save for a TRE.Bike ran awesome....

I ve had the bike in the winter months now in my heated shop ( I only bought it a few months ago around Dec time, so I haven't ridden it on the street yet ). I added a Muzzy full exhaust system. Bike ran great. I removed the flies.....bike ran great. I installed a new Shorai Battery..... bike ran great. I added a PCV... bike ran great, had slight backfire just before rev limiter or right around there (in neutral). I plugged the pair valve to the air box and plugged the hose..... bike ran great. Now day after I just installed the PCV, I installed all the remaining body panels, bike wont start. I had all the side panels off, the tank tilted back etc. Nothing crazy. I bolt all the panels on and the bike now won't start, and it will occasionally back fire through the exhaust. It turns over fine, I can hear the fuel pump. Now after trying to start the bike several times the battery is dying. I am actually bummed because this Shorai battery is supposed to be awesome. But maybe an hour tops of cranking and its almost dead? I will throw my other battery in and charge it up since I don't have a charger for the Shorai battery. I checked my ground on the PCV, it seemed ok. But to be sure I pulled the PCV off and it still wont start. I don't have any info on the TRE , but I can see where it is plugged in at, so I might disconnect that and see what happens. I am also going to check the plugs, and see if I have spark, but I would assume I have spark if I get a flame out the back of my exhaust when it backfires lol.

I have read about the tilt sensor under the windscreen. After I exhaust some options I ll check that out. I also checked the fuses, though I am going to check them again and pull all the fuses and reinstall them. I don't know why, just to satisfy my weird thought. No corrosion can be found. I cleaned the ground anyways, there was a little paint on the frame still. But there was PLENTY of bare metal exposed, now its 100% bare metal there.

No codes thrown, no FI light. I just removed the TRE and my battery is almost dead, I tried my spare battery ( lead ) and it is dead. I put the lead battery on the charger and will see what happens shortly.

With the last of the power out of the Shorai battery with the tre removed, ground cleaned, fuses pulled and reinstalled, I get nothing still. Now the Temp gauage I notice is going from cold to hot to cold to hot etc. I am not sure if that is because the battery is almost dead or what. But I don't recall that happening.

Is it possible that I hit something when I was putting the body panels back on? Temp wire or shorted it against something?

I ve read as much as I could but none of the answers the other people have gotten have helped me yet.

Any help is appreciated.

1. Work with a fully charged battery.
2. NOLTT, I don't care, go back to stock, pull the aftmkt off, this began the trouble, yes?
3. When you disconnect, look for bent pins. Find that bent pin installing the aftmrk parts, see that move?
4. The flashing water bar is a code. Go to the dash and set the display to show volts.
5. First we want to charge the battery, so the water code clears and if not, this is the no start kind of safety you may have found? Water and fan are tied in. Disconnect the temp sensor behind the engine, turn key on and see if the fan comes on. If not, there is a short and thus the water code is one variable. I doubt the bike won't start because of that, but it's battery, water code or pc ground/posi side?

1 Got the battery charging, I tried it on jump mode from the charger ( 250 amp start mode ). Still same problem. Backfires out the exhaust.
2 Everything is 100% stock right now, except exhaust system and flies out. Which should have no bearing on whether or not it will or wont start.
3 I didnt see any bent pins, I tried to check the wires going in and out of the harness and didn't see anything odd.
4 The flashing water bar is gone.
5 Where is the temp sensor located, I can't see behind the engine that well from the left side behind the main harness I see a connector, but can't seem to find good info on where that sensor is?

Also to check for codes, I turn the key, hold the two buttons on the dash for more than 2 seconds ? If I don't have a code, will it bring up the Language screen? If so that is what is happening.

Thanks

It has to error code on the display before you can 'bring up" any code numbers.If it's not doing that...it's not coding....sans...'no errors".Backfire sounds like timing/IDK.You have a stock timing wheel on there?Or manual advance wheel?Like Hub says...battery MUST be strong...12.3 or more volts.Below that...forget it.Also...when cranking...did you...OPEN the throttle and hold?Might try that as well...just to get her started.

Ok so that means no error codes than.

13.1 volts on battery now.

Still back fires. I didnt unhook the water temp sensor I dont see it. I am looking at the tilt indicator now. I dont see anything wrong with it. Just looks like a magnet. But figured lots of other threads mentioned it. Bike was never dropped but fogured might as well eliminate another item.

The only thing I haven't returned to stock is pair valve block off. All I did was plug thr hose. I am going to put that back to stock now and try it.

And I did open the throttle and it almost fired but sputtered hard.

Todd

Try pumping the throttle then...while cranking...open,close quickly(several times worth in one crank session) AS she's cranking.She's 'sputtering'...so there's fire there.IMO.I went through this as well...last year sometime.She finally fired however...so IDK what it really was.NO CODES on dash either.Battery was fine...charged up.From a previously running bike to a non-firing engine OVERNIGHT...weird...No pcv in the loop.Stock engine config with Brock's exhaust.

My 07 did this one time as well.The throttle pumping worked.That battery won't hold long if you have to do these things...so be aware of that...she may crank...yet not fire..and seem fine volts wise...

Ok I ll try that. I just put the pair valve back to stock. I sprayed some starting fluid and nothing. Checked forn pinched fuel line nothing. I can hear and feel the pump energize. I am trying to pull a plug but man you must have to have small hands......

Todd

IF there's a 'serious' issue with the motor/sensors...it'll code.If it's NOT doing that....it's something else causing it.Red lamp staying on during cranking?Pair valve,all that stuff...shouldn't cause this.UNLESS you somehow managed to loosen a connector under there.Working the throtle CAN cause flooding...so be aware of that....and watch the seconds you crank that starter...don't overdo it....5 seconds at a time or so.

You never said...but...do you have an aftermarket timing wheel in there?If they loosen...you can get exactly the same deal you're getting now.

Did you....unplug any connectors under the airbox and maybe forgot one...there's two that come off the main harness under there....usually they need to be unplugged and moved out of the way when trying to install a pair kit...that's been my experience anyway...there isn't much room you're right.I'm not referring to the stick coil connectors.

I blocked off the hose only. I didnt removed the actual reed valve setup. I figured there eas no sense in removing it. If it was my turbo busa I probably would have removed it for weight. But this is just a street bike.

No aftermarket timing wheel.

I pulled two plugs. Its flooded and they are black and soot covered. No one has plugs available right now so I media blasted them cleaned them and reinstalled two so far. I ll bet this is the problem.....at least I am hoping....fingers crossed.

The bike seemed to run rich. By like I said in the op i havent ridden it yet. Just inside my shop which i can go 80 feet lol.

Nothing out of thrn ordinary when starting. Ni lights no codes etc. Just normal cranking and a backfire. It did try to start twisting the throttle open and it did sputter a couple times. So I think the plugs is the right direaction.

Thanks

I'm going to guess you think there is a accel pump like a carb? YOu are sending in different TPS signals on a dead/cranking engine. It's do not touch a FI throttle when the closed number is what the ECU is looking for. There is no accel pump per say, now you have someone jerking off the throttle LOL... Where is your chair? Get it in front of a mirror and start putting the makeup on.

I'm not there to diagnose so it's spark plug time. You are 500 miles away from a change so might as well do it now. You have no codes, the battery cleared it when charged. Pair is not starting related. A pc is and a low battery is. Misfire can be a dirty air cleaner, rich running, the pc may have soiled the plugs... Anything but pumping the throttle.

Spark plugs was the problem......

Put PCV back on as well and its running fine. Now to reinstall everything....

Thanks everyone

Grn, how bulletproof of a bike is this? We've owned the same bikes, you should know if no code then nothing is wrong. Your abstract went off aiming for 3 paging again. Why? I have to counter your abstract and I just got lucky with this one. Why were you not on the same path I was about the plugs? Are you penultimate deficient? LOL

And you know that throttle is still a junk in number and and junk number out it goes pop out that over fat number on the backfire = load my plugs.

I should have checked then plugs first. I guess I just freaked out a little since I am doing a 4000 mile ride in a few weeks. Haven't even ridden the bike yet. So this will be a good test to see if I like it lol. Hence the reason I started thinking the worse.
