Title: Rough Runin' K11
Post by: mystic red on May 02, 2011, 08:14:02 PM
Took the bike out for season opening run yesterday and it ran good until I hammered it getting onto the 90. After less than a mile it started "surging". If I held a steady throttle it would catch and run good again. It became more noticeable pulling away from a stop but I got home alright.
My first thought was bad gas although I used SeaFoam last fall when she got put to bed. This is the first time I used that product but I heard good reviews on it.
Today, I shot some starter fluid around the injector area to see if it was pulling air from somewhere besides the air box and came up empty.
So I drained the tank, dried it and checked the filter. This was a plastic NAPA filter they said would work but when I grabbed it, it felt soft. I know it wasn't like that when I installed it. So I pulled a BMW filter out of the drawer and installed it, left the tank sitting on the workbench with the lid open to let it dry further. I had shot compressed air in there but thought it couldn't hurt to let it dry further.
I don't know if the "soft" filter could have been the prob, I guess it could have sprung a leak under pressure. I'll give it a test ride later.
 Any other ideas?

SeaFoam is for removing carbon deposits, not water.  Use Stabil or a similar product for dealing with the water issue next winter.  Also make sure you put it up with a full tank as that leaves less room for condensation to form.  (Same for your boat tank(s) too unless you have that stored inside your chalet.)

Water causes filter fibers to swell.  

Get the NAPA Gold 3032.  That has a metal case and is made for fuel injected systems.  Plastic filters are bad juju.

Edit: And there's two Ns in Runnin'.

SeaFoam says it stabilizes fuel, in fact, it's a wonder drug that does everything. Point taken on the plastic filter. I'll give her a test spin and get back to ya.

Well, I pulled the tank, dumped the fuel and dried it out real good. Put bike back together. Put a double dose of Techron (the other miracle fluid) in a gallon of gas and dumped it into the tank. Idled it for a couple of minutes and then let it sit for a while.
Then I took it out for a test spin and hammered it. Seems to run fine now. We'll see.

You should be OK.   ;D

I checked my can of SeaFoam.  It does say it dries out fuel but I don't think it will do as well as a product specifically formulated for that task.

My Dad was a boat racer and used SeaFoam all the time with his F Hydro's. Continued using it in the years he was sailing (diesel) and still with it with his bus (motor home). I have used it with my ski boats and also my Kawa Concours. The Concours was lagging at the throttle and a add of SeaFoam to the tank cured the carb problems. Some years later with my Concours, a second time of throttle lag, SeaFoam helped some, but I also eventually had to pull the carbs and clean out the idle jets to get everything running smoothly. SeaFoam has been around it seems forever, and is great stuff.
Title: Re: Rough Runin' K11
Post by: frankenduck on May 19, 2011, 12:51:25 PM
My personal rule of thumb is to use SeaFoam for carb'd motors and Techron concentrate for FI'd motors.  (Techron doesn 't remove water from fuel that I know of.)

As a fuel system additive, Sea FoamŪ will clean carburetors, fuel injectors, clean carbon, gum and varnish deposits, add lubricity to fuel, stabilize fuel for 2 years and control moisture.
As an oil system additive, Sea FoamŪ controls moisture, gum, varnish and residue deposits.

Will any ol beads work such a old ball bearings?

I heard they use the beads in washing machines so they don't go imbalanced in spin.

What do you know about the beads please? :)

I believe he's referring to dynabeads.  Some swear by them and some call them snake oil.  But using beads/ball bearings in tires has been around for awhile, at least in semis and large-tired 4 wheeelers.  I've never used them, but don't doubt that they work.  YMMV.

After changing the fuel and fuel filter it doesn't run rough but two straight tanks I got 33MPG, down from 45. WTF! Only thing I did to it this spring engine wise is spark plugs.
These plugs right here:

http://cgi.ebay.com/ebaymotors/NGK-Spark-Plug-92-98-BMW-K1100LT-Platinum-Iridium-NEW-/150610404084?pt=Motorcycles_Parts_Accessories&hash=item23111462f4 (http://cgi.ebay.com/ebaymotors/NGK-Spark-Plug-92-98-BMW-K1100LT-Platinum-Iridium-NEW-/150610404084?pt=Motorcycles_Parts_Accessories&hash=item23111462f4)

That wouldn't cut fuel mileage. O2 sensor? Temp sensor? Seems to run O.K. but not with the snap it should, IMO.
What would cut the mileage like that?

What's your exhaust residue looking like at the back of the can. Dark and sooty or light grey? Maybe pull the plugs and see what they look like to see how they are burning.

Yea Scott, I checked that when I got off today. Dark, but no different than usual. I will pull the plugs and check them out. They've got 250 miles on them so the should look fresh.
Duck, I expected more outa you. Bad brake joke and no advise. :P
Title: Re: Rough Runin' K11
Post by: Scott_ on May 25, 2011, 09:51:56 PM
I suppose you could possibly have the temp sensor giving the motronic a bad engine temp reading so that the mixture is then causing poor mileage.
My exhaust is black and very sooty, but yet I still am getting 45+ mpg. Even after my 4300 mile trip last month it's still dark and grainy, so I don't think it's because of short trips.
You say you changed the fuel filter, how's the air filter.

Did you put screw-on caps on the spark plugs?

Double-check that the spark plug leads are all of the way on?

You should synch the TBs any time you change plugs.

Have you checked for air leaks between the TBs and the cylinder head?  (Spray some starter fluid there while bike is idling.)

!. Yes

2. I will.

3. Agreed but that would not account for the horrendous drop in mileage.

4. I sprayed starter fluid in there once with no reaction but will address this more closely.
I think it is some sort of air leak, possibly, as there is deep, almost leaky exhaust manifold sound coming from the engine.
What about vacuum leaks? Air box leak? would these cause a drop in MPG?
Title: Re: Rough Runin' K11
Post by: frankenduck on May 26, 2011, 07:37:05 PM
The air is mixed in the TBs.  I don't think anything before there would cause such a huge drop.

Title: Re: Rough Runin' K11
Post by: frankenduck on May 26, 2011, 09:25:13 PM
Is it still running rough or does the mileage just suck?

I suppose another thing would be to check the resistance of all of the coil wires?

How many miles on your fire engine these days?
Title: Re: Rough Runin' K11
Post by: mystic red on May 27, 2011, 06:25:25 PM
Close to 80K. It idles fine. When running down, the road if you hammer it, it doesn't seem to pull very strong.
Title: Re: Rough Runin' K11
Post by: frankenduck on May 27, 2011, 06:37:11 PM
Has the air filter ever been replaced?

It sounds as though it might not be getting enough fuel if it's not pulling strong.

It might not hurt to have the FI's cleaned by our friend Mr.Injector.  Since you have to let is sit up every winter maybe there's some varnish built up in them.  It doesn't cost too much and certainly can't hurt.

That K1 I just bought had 82k on it when I got it.  One of the things I did to it was put reconditioned FIs in it.  It runs like a top now.  I did other stuff so I can't attribute it all to the FIs but I'm sure that didn't hurt.

JO's motoheap has over 100k on it so I"m gonna help him install some recondtioined FIs this summer before MotoDungee 2011.

If the spray pattern isn't misting the fuel properly then you might not be getting optimal combustion.

Mr. Injector is a feller in Idaho who reconditions FIs.

O.K., I got the spark plug wire on proper and took it for a test spin. Now I'm back to the surging deal. It will stall a little and then run like it's supposed to once it get through the surges. Spark or fuel. New fuel filter. Pulled the plugs (new) and they look text book. Gapped correct. Light tan, not wet. Checked resistance on the wires, 5.9 to 6. What else, coil ground, fuel pressure test? Don't have a pressure tester but that seems like it would eliminate a lot of crap. It's starting to get nice here and I want to whine....errrr.....get this thing running like it should. ???
If it was injector problems wouldn't it show on the plugs and wouldn't the bike always run ch!ttie?
Title: Re: Rough Runin' K11
Post by: frankenduck on May 31, 2011, 09:45:14 PM
Have you checked for air leaks yet?  As you up the RPMs the vacuum can make the leaks seal themselves which might account for surging.

Got anything to synch the TBs with yet?

Yea, I sprayed starter fluid with no change in engine speed. :(
Title: Re: Rough Runin' K11
Post by: frankenduck on June 01, 2011, 02:58:50 PM
I'd send the injectors in to Mr. Injector.  Even if it's not the injectors then that will eliminate them as a possible cause and IMO, at 80k it's good preventative maintenance anyhow and relatively inexpensive at $69 total.  It certainly won't make things worse.

The K1 had 82k when I got it and ran a bit rough but after I installed recon'd FIs it ran much better.  Yeah, I also put in newer coils/leads and fixed an air leak but I'd guess that the FIs played some role in making it run so much better.

(FYI: I'm going to help Johnny put some recon'd FIs in the motoheap when he's up here in July.)

The reason I ask about the TB sych is that that's a good way to diagnose air leaks.  I found the air leak on the motoheap and the K1 that way.  On each bike I couldn't synch one of the TBs which is how I knew there was an air leak.  It's a bit more reliable than starter fluid to diagnose things IMO since if the air leak is on the back then the starter fluid might not get sucked in.

Get thee a TwinMax or a CarbTune.  You can use it on wifey's ride too.

O.K., here's the deal. Gots a blown #5.

(http://www.maxbmwmotorcycles.com/fiche/DiagramsMid/B0000199.png?v=03252011)

 They call it a bushing. It's the rubber connector on top of the intake manifold. Seven $ and change and I need 4. Gonna do the vacuum line and fuel lines (can see cracks in the one that attaches to the fuel rail) that attach to the fuel regulator while I'm there. Injectors will be cleaned. Any more parts to be replaced while I've got the fuel rail and a it stripped to the intakes?

I'm down for a while it looks like. :'( :'( 

I decided while writing this to add four 3s. Just in case.

And here's a great tip when looking for vacuum leaks. Get yourself a 1# propane tank and attach a torch to the top. Then tape up the breather holes on the torch and attach a piece of flexible hose to the end of the torch. I used a piece about 4 feet long.
Start your engine, turn on the propane and use the hose to pinpoint the leak. You can put the hose right where you want to check for leaks.
Safer and  more accurate than starter fluid or other flammable sprays.

Why do you need to f with the air box?  Leave the top of the air box and those hoses as they are.

You can put those bolts in that secure the bottom of the air box once the filter is out and not having to remove the top of the air box.  I did it just yesterday on a K75 I was helping a guy with.

MR, sounds like you are doing to yours what I did to my '95 during my winter '09 teardown. All of the rubber o-rings, hoses, fuel lines, vac lines, cooling hoses, clutch disk and engine output shaft seal(was leaking and started the whole teardown ordeal).

Runs better, but I think that there is still room for improvement. I'm thinking the injectors need done next as I should have done them at that time but didn't.

I didn't take it out but the short hose came off and I haven't been able to see where it hooks up to. They aren't even shown in the fiche. So my original question still stands, are they necessary?

I bet the short hose hooks to the big hose junction on the back of the fuel rail.

My lower box just rattles around in there. No big deal until you try to separate the upper from the lower to slide m/f-ing air filter in. Then THAT turns into a 4 man job.
Any idea about the hoses? One runs down to the crankcase connection, where the fuel vapors used to be routed before I 86'd that by installing the "air accumulator".
I think those hoses are Cali emission ch!t.

Don't feel too bad, mine didn't have any bolts fastening mine down either. It just sits there on some rubber pads. They do have a little nipple on them to set into the hole in the block for horizontal alignment, but no threaded bolt to fasten it down solid.
I can't remember how much time I wasted trying to remove them only to realize that the airbox bottom just sat there and was not fastened down. :o

I did replace the smaller rubber hoses in/out of the airbox. I'd have to find the packing list to get the part #'s if you would like.
IIRC there are 3.
2 on the front and 1 on the left rear.

If I was doing it again, I'd eliminate all of them like some others have done. I think it's also what BMW did on the 1200's.

I'll probably eliminate them on my '97 when I renew the rubber bits on it next winter.

If I was doing it again, I'd eliminate all of them like some others have done. I think it's also what BMW did on the 1200's.

I'll probably eliminate them on my '97 when I renew the rubber bits on it next winter.

So these hoses are not necessary? Can you just cap them off and do away with them? Emissions crap?

Just asking: if you close off that system--the vent hose connection at the rear and the return hose connection at the front--won't you blow a seal?

That's what I came up with, Larry, not worth the worry. I'm keeping it as is. ;D
It also looks like the short hose on the back is to bleed off air not required for the throttle bodies and is re filtered. If I'm wrong I'm sure I'll be bitch slapped by a crazed waterfowl.

To a point. Most can be bypassed and re-plumbed together. You are still maintaining the vacuum to the block, just doing it thru the throttle bodies and not the airbox, and eliminating the "cyclonic oil separator" that never really worked either.

You should use some JB Weld to seal up the valves.

It's 20 year old plastic on top of an engine that's seen 80k+ miles and doG knows how many heat cycles.  Not surprising to me at all.

I moved my little pictorial of the intake manifold and fuel rail removal to K1100 Intake Manifold Rehab (http://www.motobrick.com/index.php?topic=624.0) so it would be easier to find. I'll add to it when I put it all back together.

I'm just about to say "stick a fork in me". Ran better with the air leak fixed but I only got 110 miles before the low fuel light went on. Pulled the plugs when I got home and #4 was black and wet.. Going to try new plugs cause this thing hasn't run right since I Ebayed those NGKs. F me runnin'.

Cap was probably loose on #4.

Post by: Scott_ on June 20, 2011, 07:16:52 PM
Well didn't he say he had a loose cap on #1 a week ago or so? and since 1 & 4 share the same coil, it's not supprising that #4 hadn't been firing either.

Check that the resistances on your coil wires are in the same range.

Sell it to me for a grand.  I'll be there tomorrow with my trailer. :-*
Title: Re: Rough Runin' K11
Post by: mystic red on June 20, 2011, 08:35:58 PM
Sorry, I meant #1. Same one that doesn't want to sync. Cause it's not firing.
The thing is, I go back to work tomorrow and don't have time to dick with it before the weekend. If I was sure it was a coil and you had one I'd ride it to Clarkston and swat out in the parking lot. That seems like the only thing it could be though, right? Plug wires have the right resistance. I'd really like to go on this trip but I'm not goin' running a suped down K75. :'(

Did you check the screw-on caps on the plugs?

And it would be a K82.5, not a K75.

Called jo and he said, duh, pull the #1 and see if if sparks connected to the wire. Yea, it sparks, right out the side of the wire to the engine and then down through me. Did it again (kinda liked it) and I found a cut in the wire. Magnecor to the rescue.

If'n you can't get one there in time then I can Priority Mail one to you and it should be there in a day or two since you're close.

And why do you put cuts in your spark plug leads???
