Problem with 919

Need advice. Something's wrong with my 9er. It's sputtering/cutting out when approaching triple digits. Almost like the rev limiter is kicking in but that's not it, revs are only 6-7K. It pulls strong all the way up to about 95 mph then the sputtering starts. My first guess would be plugs but the bike only has 15k miles. I wouldn't think it would need plugs that soon but what the hell do I know. If a plug is bad wouldn't it miss across all rpm ranges? I haven't changed anything on the bike in months.
Any input is greatly appreciated!

Steve

Don't know what they specify for the service intervals in the US, but 15k miles = 24k km's, which is a major service: valve clearances & spark plugs. But still, that doesn't sound like it could be your problem.

Are you receiving any error lights on the gauges?

Do you have a PCIII? If so, you may want to try disconnecting it.

Bad/old gas? - Been there done that. Learned to fill up at reputable stations only.

Fouled plug(s) - Been there, done that. Mine was caused by a fuel line clamp being left on the fuel return line and causing a super rich condition. See this link too...fouled plugs yet again - Wrist Twisters

Those are my best guesses.

Also, I experienced similar issues when I had a wire going to one of my coils break. It was broken only inside the jacket so the wire looked good, but occasionally lost connection. It would sputter and lose power, similar to hitting the rev limiter, then kick back in for a bit, then puke out again. Eventually, after about a mile or so of doing this, trying to limp back to the office, it just ran on two cylinders only.

Air filter or fuel filter? I don't know why it would only do it at a certain road speed, usually it's the engine RPM. Does it do it in several gears, or only in one gear?

Bike is all stock except for cosmetic stuff. Filled up with exxon gas and the problem didn't change. It only happens in 6th gear running WOT but it is very noticable then. My first instinct is to swap plugs but I would think it would miss at all rpm's if it was plug related? I need to check the coil wires I guess, that seems a likely culprit. I did have my big crash back in september. Me and the bike slid down the highway at 70 mph for a ways but it has ran perfect since I got it out of the shop. I think I'll go ahead and change the plugs this weekend and try to check all the wires and go from there.

Thanks for the help guys!

Ha! I remember your post on that a while back. Lmao! I won't attempt it without one. I'm not known for my patience anyway. Already called the dealership but they are backordered. If anyone has a spare I'd be happy to paypal ya, otherwise I guess I'll try ebay.

#3 plug is not that big of deal, just get a flex swivel for your rachet and you'll be fine.

Scott, that's good to know, thanks. I already have one somewhere. Finding it in a reasonable amount of time is another matter entirely. Luckily there's a northern tool right up the street.

As for running worse in 6th at WOT...

This may be off mark, but WOT in 6th at 5 - 6K RPM would probably be running pretty rich.

Does it do that at WOT in other gears? I've had a partially clogged fuel filter that only caused problems when I really hit the gas. Just a guess.

I've only experienced it in 6th gear WOT when I was at or near triple digits.
It runs great in normal non-holligan mode. I can lift the front wheel at will.
No power problems whatsoever in the lower gears. I'm going to experiment tonight and see if I can duplicate the problem in 5th gear WOT.
I'll post up the results tomorrow. Leave it to me to come up with some weird never been seen before problem.

It's time for the service. Plugs, air filter, all the normal stuff.

I bet it runs better than ever once that is done, if it is done properly.

Found this handy little chart someone made up for you 919'ers

The little chart within the chart is the Honda flat rate times, in hours, for each of the services.

For a good price estimate at a shop, take the hours times the labor rate and double it to cover parts/misc.

That will give you a really close dollar amount to budget, usually on the high side.

Like usual around here, I'm going to have to solve this mechanical problem!!!

As the other have said, kind of, your bike needs a full service. Until you have done that, trying to solve this problem could be a complete waste of time. So, please do the service, all of it, and then get back to us. If you still have a problem, I'll gladly tell you what is wrong, then.


PS--- If anyone thinks I'm serious about that first line and last line, get help or drink less.

Exactly when did it first start happening, and what event can you think of that just preceeded that time frame ?
Has the condition got worse with time, or is it the same as when it started acting up?
These some of your first questions.
I see you had a major getoff with battle damage, but it ran great after the repair.
What were the electrical (wires & connectors, switches and sensors) elements of the repair, if any?
What were the fuel and air intake elements of the repair, if any?
Perhaps some of that recent work has failed and is part, or all of the cause of your present problem.

I appreciate all the advice. I think I'll do the service like many of you sugested and see where it's at after that. I needed to do that anyway. I don't reallly think the problem has anything to do with the getoff 3 months ago. It has ran perfect since getting it back from the dealer until this week.The frame-sliders did their job. All the damage was cosmetic. Probably just needs a set of plugs, we'll see. I'll post up the cure once I figure it out.

That was one you should've resisted, paco.

I'm on the border of Richardson/Garland. Work at Juvenile Detention (watch out, paco) off I-30 & Hampton. Ride to work most days it's above 45 in morning and not raining (i.e., not so much lately). We should hook up for a joy ride some weekend. Just don't expect me to have a Honda tool for that #3 plug!

Cool, yeah we should hook up sometime. I'll pm ya my cell and I promise not to hit ya up for the plug tool. I try to ride everyday even in the cold unless it's pouring rain cause it saves me $7 parking and I can take the hov which saves me a ton of time and frustration. Supposed to be 29 in the morning but I will gear up for it so I can get to work in 17 mins instead of an hour or more in my truck.

Dallas traffic is the worst. Just moved back to Fl, was living in McKinney. Miss the country roads though we don't have much like that here in the bay area.

k d makes a long spark plug socket with an attached swivel extension and a magnet that holds the plug on,you wont believe how easy it makes changing the plugs on the 919. sears has them online in three lengths,make sure to get the long one.

Sounds like a stocking stuffer to me. I'll have to look it up and email the link to the spouse. Much better than my annual lump of coal.

It's in the optional (on later 919s) tool kit. I bought the optional tool kit after getting my '07 919 and it has the plug wrench.

Links for online purchase in this thread:

If you're going to do plugs, 2 things: get the plug tool from Honda (mine came with one in the tool kit) and get new plug wires and boots. I found the boot on #3 cracked. It was causing low rpm stumbles, but still could be a problem.

Contact me for AMSOIL products!

www.rmbsynthetics.com

If it ain't broke, keep fixing it 'till it is...

Where is the best place to get plug wires/boots from? can you get them for the 919 in any color other than red?

Well, fire the engines! Spur this iron space-pony on!
