Bike Will not start?

Hey guys,

I'm finishing up my projects on my 919 for the Winter (renthal bars installed, painting my grey parts matte black) and I am eagerly awaiting warmer weather and street cleaners.

That being said, I tried to fire up my bike quick the other day and got nothing except a few backfires out of the mufflers. I tried again today with a charger attached because my battery died on me, and again, nothing but some backfires. I pulled the choke on, left it off, gave it a little gas, which probably only complicates the issue, and left the gas alone. The gas tank has fuel in it, with some stabil from late fall.

I have started it every couple weeks this winter just to warm it up a little bit, and the last time, about 2 weeks ago, it fired up just fine.

I cant quite figure it out. Any ideas on this?

Try draining the old gas out and putting new in? Spark plugs?

+1 to the post that said "check what you touched last"

Check everything on the handlebar - especially the clutch cut-out switch and the throttle cable. If the throttle cable is a bit tight, it might be opening the throttle butterflies and making it difficult to start.

Sounds good. I think I'll start by tearing down the handlebars again. Gas should be good right now.

Thanks guys. We'll see what happens.

idle screw

Anyone know how many turns from fully closed the idle screw should be set at?

If you're referring to the yellow-knobbed adjuster, then adjust it until your warmed-up engine (idling) is spinning in the neighborhood of 1,200 rpms. I don't remember reading anything in the shop manual about an 'adjust from zero' instruction.

Hi there, well I have no idea. I've checked the sidestand, messed with the yellow idle screw, tried starting in full throttle to shut off the fuel and everything else.

I did mess with the throttle lines, so now I have no idea where they are to be set factory.

3d, I just painted the side covers, exhaust covers and passenger handle.

I think I will need to check the plugs. Is this a fairly time-consuming ordeal? It looks like it is according to the manual.

The bike has only 4000 miles on it. Should the plugs fould that fast? Is the back-firing a hint of that? Sorry, I'm not the most engine-savvy when it comes to understanding them.

As stated above... bike ran good before you changed the handlebars, correct?

What exactly did you do to the throttle cables? There should be a ever so slight play in the throttle when it is closed. Twist the throttle then let it go. Do it snap back by itself without binding?

The switch housing contains the starter button and the red rocker kill switch.

If a wire was broken on the starter button or the kill switch the bike would not turn over.

Jared: We are under the assumption the bike turns over... Correct?

The slack in the throttle feels as it should. It does snap back. I'm losing my mind over this.

Hi,

Yes, it does turn-over. Just wont light. Any fuel introduced with the throttle creates a rumbling sound in the exhaust and a very loud backfire.

Just re-read your 1st. post. It stated that you started the bike a couple of week ago. Was anything done to the bike after it was running? It is not clear if the mods. were done before or after the bike was last running.

The bike was running before and after the mods. That's why I'm not sure what the deal is.

Sorry for the 101 questions... It's not easy to troubleshoot over the net.

When you did warm it up every couple of weeks, how long did allow the bike to run. BTW: I would never recommend this procedure, you do more harm than good.

Battery Tender - Stabil, fresh oil/oil filter, done until spring.

no problem. I completely understand. I only allowed it to run for a few minutes just to warm it up.

In that case, I would suspect fouled spark plugs. Pull them out and post up a pic or two. The pugs are not the easiest to remove, are you up for the task?

Read Jared's post. Kill Switch in the OFF position - You get nothing!

It wound help if you had supplied ALL the information. Forget about the spark plugs, you have a more technical problem. Follow the PGM-FI self diagnosis as outlined on page 5-10 of the shop manual.

So the spark plugs probably arent the issue then huh? I'm assuming the "shop manual" is different from the owners manual correct? Do I need to get this through Honda directly?

You'd think that buying a brand-new, 0 miles bike from Honda, you could get a little more than 4000 mi. out of it without having to worry about this stuff. I havent done anything drastically to my bike as far as mods. New bars, and the bafflectomy and taking my rear tail-lights off. I've owned a Honda Accord and an Acura TL type S and never had one issue with either one of them.

If I have to start throwing money I dont have around already on this bike, (towing cost, repair cost, parts) and dealers telling me because I did a couple mods they wont touch it, i might be better off cutting my losses and selling the thing. I'm really frustrated right now.

Thanks for all the help you guys have given me on this. I DO appreciate it.

You need to slow down a little, don't need to go to drastic measures like selling the bike.

I'd still take a look at the plugs first, regardless of the FI light.
At least the easy ones.

The FI light should stay on till the engine has started. I may be wrong, but I don't think so...


It is a Honda, after all... :

Don't sell it! it is usually the simple things that frustrate us! it is rather easy to check the plugs, you can even get the outside ones out w/o having to raise the tank. it should have the color of a beautifully toasted marshmallow... One reason it's good to just let it be stored in the winter (without starting it) is that it will load up on fuel... and even when it comes up to temperature in the garage, it takes a while to run it out of the system. In extreme cases of flooding, fuel will wash down the cylinders and mix with your oil, reducing compression from not having a wet seal between the rings and cylinders. This will also prevent starting, but can be remedied with an oil change.
Step 1: check plugs. they can be a tell-all!

30,000 mile 919 survivor. No plans of stopping the abuse any time soon.

It is a Honda, after all... :
OKAY. I walked out to the parking lot and tested this. The FI light comes on briefly when you turn the bike on. It goes off about the same time the fuel pump quits priming the system. It does not come back on when cranking either.

However. If anyone remembers this thread... https://www.wristtwisters.com/forum/s...ad.php?t=15908 ...then you may remember me having issues with the bike starting.

For whatever reason, the kill switch was about halfway cocked when I took off for the day and it flipped on/off/whatever and killed the bike as I was going down the road. With the kill switch triggered, the FI light came on.

Of course, it didn't turn over when the kill switch is engaged, but since you replaced the bars, maybe somehow the switch is killing power to the coils but allowing you to turn over the starter...is that possible? Don't know...just grasping. Check the plugs.

Did you get a tool-kit with your bike? You should have. It will have a plug tool in there. I find that it is quite easy to just lift the tank, prop it up with by putting a short 2x4 between the tank and the frame (run the board left to right with the bike...not along the frame) then use the plug tool, a ratchet, and I think a 10 MM socket. This is much easier than the way the manual recommends.

If all else fails, you can find a friend with a truck/trailer and have them help you take it to the dealer for fixing under warranty.

Press Any Key To Continue.

Okay. Been a long couple days. Thanks again everyone for the help on this. I am going to get a look at the plugs today. However, I was one of the people that bought my bike brand-new and didnt get a tool kit. Can anyone recommend the size plug socket I need? I did a search and couldnt come up with anything. Any certain other attachments that might be useful in getting the plugs out?

Thank Tom. Got the wrench.

Well here's what the easy ones look like right out of the bike: To me, they are plenty dirty. Would cleaning them be the best option? Or just order some new ones?
