Question In need of engine diagnosis on '03LT

OK folks, I've noticed a miss in the engine at idle and when first moving out. At high RPM's I can't hear the miss.

This shade tree mechanic has done the following with no good results:

1. adjusted the valves to make sure I didn't have a tight/leaking valve. It was time to do it anyway.
2. replaced all 4 sparkplugs
3. placed a used injector at #3 cylinder as I thought that was the culprit due to the color of the plug in that cylinder when I replaced the plugs.

I took a ride yesterday and it performs the same way so I made no improvement.

The next thing for me to do in my opinion is to load it up and take it to Engles in Kansas City and have them do a engine diagnosis. I haven't called them to make an appointment as yet.

Sooooooooooooo, if someone here on this site is excited about using their GS-911 on my bike PM me.

Also, if I've missed performing something simple that I should do before hauling the bike to Engles, then chime in. I don't have anything to do a compression test as that has crossed my mind.

Please note that I now have 149,777 miles on this bike/engine. If this turns out to be a major engine repair, then I'll be looking for a used '03 or '04 LT to buy with fewer miles.

So fire away and thanks for this outstanding site to vent on and to obtain super info.

Re: In need of engine diagnosis on '03LT

Vern,
You didn't mention it in your post, but what have you checked for spark? You could have a wire that is leaking spark. It is hard to see the small holes that will leak spark,try looking in low light. Another check is to gently mist the wires all the way to the plugs with a fine water mist. It won't hurt anything, just don't drown it.

Talking Re: In need of engine diagnosis on '03LT

John,
Hadn't done that. Guess I could see that at night. I have pulled the plug wires one at a time and it bits like hell. LOL
But I guess it still could be jumping off someplace it's not supposed to.

I didn't think about the plug wires. Maybe I sould take them off one at a time and give them a good going over.
Thanks for the tip.

Re: In need of engine diagnosis on '03LT

A vac. leak will cause a miss at idle that goes away with RPM.
At idle spray WD40 around the intake gaskets. If there is a leak RPMs will go up.

Re: In need of engine diagnosis on '03LT

Good suggestion from John. IIRC, It has something to do with amount of voltage needed to jump the spark plug gap, and I can't remember if more voltage is needed at idle or less, but seems like that's why it's more noticeable. If this doesn't pan out, then here's some info I found online:

Lean Misfire
The lean misfire is another common reason for an engine "miss"—this is due to an imbalanced air/fuel ratio (too much air/too little fuel). Since an engine needs a richer (more fuel) mixture for a smooth idle, this problem may be more noticeable when the vehicle is idling. The lean misfire may decrease or disappear as the engine speed increases because the efficiency of the volumetric flow into the combustion chambers increases dramatically. This is one reason why a vehicle gets better mileage on the freeway than in the city. An EGR valve that is stuck open, a leaking Intake Manifold Gasket, a defective Mass Air Flow Sensor, a weak or failing fuel pump, or a plugged fuel filter are some of the many causes for a lean misfire.

The information was regarding automotive engines, but the info is applicable to m/c as well.

Re: In need of engine diagnosis on '03LT

Check carefully where your wires pass through the end of the plate on the valve cover. They are prone to leakage at that point. You can try running it with the cover removed and applying some electrical tape to the wires at that point. Not a permanent fix, but a good diagnostic method. Also look for continuity in each wire. Note that the resistance is linear and corelates with the length of each wire, but each one should be measurable.

Actually, I don't think the miss goes away at higher rpm's I just can't hear the miss like I can at idle. It dies at a stop sometimes but will still run 90 mph in 3rd..

Jeff, you brought up a lot of good questions/ likelyhoods for my search in your post. Thanks. I wonder if any of those symptoms show up on a GS-911?

I just now sprayed water over the wires and ran it in the dark. No visible sparks nor did it affect the engine speed.

I don't use wd40 (just ether), but I don't want to use ether for a vacuum leak test. (BOOM) Next time I'm in town I'll get a can of wd40.

Thanks fellows

Re: In need of engine diagnosis on '03LT

Another good diagnostic tool is a propane torch. Just open the valve and put it close to the intake system (unlit of course). The propane does the same thing as the WD 40 and leaves no mess. WD 40 doesn't work quite as well as it used to either as I think they changed their propellant to something non-flammable.

Dean, the propellent used to be butane/propane but they changed it since we were using WD40 for unintended purposes (like seating flat tires on the bead). Either that or some other silly safety related reason.

you have done a compression test haven't you, and not just check valve clearance?

Re: In need of engine diagnosis on '03LT

Can't remember but does the LT still have the little rubber caps on some vacuum connections at the base of the throttle bodies? I know my 85 K100 RT did and these were prone to cracking and leaking. With 150K on the clock the seals between the throttle bodies and the head could also be getting hard from the heat / cooling cycles. These were bad on My 85 but it was also 20 years old at the time.

Re: In need of engine diagnosis on '03LT

each wire should be very close to 5 ohms - had a pretty good miss in my k100 was plug wire - my k1100 plug wires were cracked and had holes but engine ran perfect even wet

Nope, haven't done a compression test as mentioned above.

I looked at the #3 plug again and it's oily so I'm thinking something serious. IE broken ring/cracked piston/Ugh! Might try another spark plug and some "restorer in a can" before I get another LT. If I get an '03 I'll have a whole bike of parts to use/sell. There is an '03 LT in the classifieds that's the same color as mine. I may have to go to Alabama to see it. The owner hasn't given me any details about the bike yet.

Oh well......................spring is getting closer!!!!!!!!!!!!!!!!!!!

Re: In need of engine diagnosis on '03LT

Mine has an "oil wet" #4 cylinder. Smoke clears up shortly after cold-startup and I have to watch the oil fill level to always be lower than halfway up the sight glass hot oil engine off for at least 10mins.

I wanted to do compression test but so far can't find reasonably-priced tester with that tiny of a plug thread. Anyone have a recommendation?

Look around like beemerboneyard.com and ebay you can find good used motors complete for under $600. If your bike is otherwise in good shape that's probably the way to go.

Afterwards take your time, open up your old motor and see what's wrong. They use the nicasil (spel?) chromed cylinders so a really bad scratch may not be fixable in the cylinder bore. Correct me if I'm wrong.

Re: In need of engine diagnosis on '03LT

You are correct. At least for a reasonable cost that is. I understand it can be done but it is expensive. Far easier to swap in a used engine. Steve Rowe had low compression and high oil consumption on his bike. Otherwise it drove fine. This post shows what we found. Also upon further disassembly I found all pistons had fractured ring lands, but just the one broken ring.

Talking Re: In need of engine diagnosis on '03LT

Update.....................I decided to call the Stealer in Kansas City to get a diagnosis. They scheduled me for next tuesday afternoon.3/12/2013. Hope they can decifer the problem then I'll decide what to do. For sure, I won't have them fix it at $84 bucks an hour.

After reading the last post about a chunk out of a piston, I'm thinking I have something similar to that.

I've had the intake off my bike to replace the vent hose assembly on top of the engine once and that was 45,000 miles ago. Even though I used rags to prevent something from falling in the holes, it is possible something hard could have dropped before I got it back together. I didn't hear any "crunch" when I started it up though. LOL

I'm really slow at mechanicing so I sure wish spring wasn't so close. Ugh! I don't think I want to attempt the "a used engine route".

Thanks for all the ideas/help.

Thanks, Gary. This bike doesn't owe me anything, that's for sure. But sure hope it turns out to be something simple that this shade tree mechanic didn't find.

I have the bike loaded (accomplished right after Church) today as they are calling for 2" to 4"s of snow tonight. Me and the LT don't like snow much under foot . LOL So hope the roads are clear by tuesday AM so I can get to Engles with the bike on the trailer. It's about a 100 mile trip one way.

Stealer diagnosis completed this afternoon(3/12/2013).

It taint good.

Bad piston/ or vavle in #3...................no compression at all.

I've pretty much have decided not to fix it, even with a new motor, as I'll still have a bike with 150 K on it.
I am going to try to take the bike apart. It'll give me something to do until I find another bike.

After seeing a '06 for $10,000 here on our site, now I'm wondering about the validity of the bike I'm interested in on our classifieds. Poster is from Ohio and the bikes at a dealer in Alabama. Can't trust anybody anymore. Certainly not safe to take someone's word.

Vern,

There are several nice ones in the Denver area, sent you a PM with links.

Here is a nice 2000 nearby:

Re: In need of engine diagnosis on '03LT

If you look around you can download the service manual. You can pull the pistons with the engine block in the bike as far as I know. My cyl #4 is weak.

But I think the cyl head needs to come off. Right side there's a big plate for access to crank I think. I've been looking at mine to see how feasable that is.

Still have to find a compression tester or adapter. Mine is just regular size plugs for a car. The K plugs are tiny. Still can't find what the diameter is, I think 10mm but have to double-check.

Hi,
Actually the size is 17mm. I didn't have a compression tester either. That's one reason I took it to the dealer.
The trouble with fixing the engine is that I'd still have a bike with 150,000 miles on it. Brake lines are due to replace, rear main engine seal was beginning to seep oil, mirrors are in terrible shape and one side I'd glued together several times, I'm sure there are other things I'd need to attend to as well, so thus my decision to buy a used LT with fewer miles. True, I may have to fix some things on it too, but I'll take that chance.

YES, it is possible to replace a piston while the engine is still in the bike. I could do it myself, but I'm nearing the age of 73 and just don't have the energy to do it and besides, it would take a long time. LOL Putting a head back on requires a really clean work place and I don't have that either.
Bottom line is, I'll be back riding much quicker if I buy a used bike and that pleases me more than wrenching on one.
Thanks for your interest.

Yep, that's the plan.

Gotta make a space to hang it in the garage and clear some shelves for parts. If I don't do that I'll be tempted to fix it. LOL

Re: In need of engine diagnosis on '03LT

Well if you're still riding at 73 good for you.

The plug hole I believe is 10mm, yes the socket for the plug is 17mm. But the compression tester threads into the 10mm plug hole.

I just bought this one, try it next week: http://www.ebay.ca/itm/Engine-Cylind...item1c282dcf51

I understand your sentiments. I don't think anyone buys these to work on them as opposed to riding them

Assuming you had access to some room or facilities, it could make for some good tech sessions with you supplying the bike and parts, while others wanting to learn and/or give their hands dirty could supply the labor. Don't know how many enthusiasts are near you, but you could even have a tech session or two just removing parts, instead of you having to strip it down yourself.

Just some ideas. :

I called yesterday to see about the bike and found out it is sold already. Thanks for your offer, however.

Found an '02 near St Louis I'll check out tomorrow. I will call them this afternoon to make sure IT hasn't sold.

Jeff,
I'll look into that AFTER I get something to ride. LOL I can only have one project at a time.
I've not been to a tech session so one way to solve that is to have one. No one close around here that I know about that would have a good place(garage/shed to have one.

Talking Re: In need of engine diagnosis on '03LT

Thought I'd brimg you all up to date.

Brought home an '02LT, Silver, with 80,000 miles on it; Soooooooo I went backwards a year and a bunch of miles as the '03 went 150,000..

I'm in the process of removing the 1100X PIAA lights from my '03 to the '02, and the cruise needs tuned up as it's not working. The checks go OK til the trottle switch. I have to remove the tupperware on the left side to add the PIAA lights so I'll check that switch when I do that.

Nice that it doesn't have a single ding on it. (never dropped) I expect I'll add one before the summer is over. LOL I manage to lay it down about every other year, although it has been quite a spell since I'd dropped the '03.

Well, I guess I'd better update my signature too.

Be interested as to the root cause of failure.

Was it piston failure or valve?

Yes, me too. Been working at it til my fingers get cold then it's back in the house to warm up. I haven't even got a wheel off yet as I seem to ride the '02LT about every day. In fact I'm going to the pharmacy, as soon as I read all my emails, to slow up my drippy nose. The weatherman keeps telling me it's gonna snow so can't be out on the road very long at a time.
If and when I get the motor apart, I'll post my findings.

2. replaced all 4 sparkplugs
3. placed a used injector at #3 cylinder as I thought that was the culprit due to the color of the plug in that cylinder when I replaced the plugs.

I took a ride yesterday and it performs the same way so I made no improvement.

The next thing for me to do in my opinion is to load it up and take it to Engles in Kansas City and have them do a engine diagnosis. I haven't called them to make an appointment as yet.

Sooooooooooooo, if someone here on this site is excited about using their GS-911 on my bike PM me.

Also, if I've missed performing something simple that I should do before hauling the bike to Engles, then chime in. I don't have anything to do a compression test as that has crossed my mind.

Please note that I now have 149,777 miles on this bike/engine. If this turns out to be a major engine repair, then I'll be looking for a used '03 or '04 LT to buy with fewer miles.

So fire away and thanks for this outstanding site to vent on and to obtain super info.
Vern
Here is an UPDATE to this 3/22/2013 post.

Today I got the head removed from the engine and found a chunk gone out of the top of the piston. Now I know WHY I had no compression in cylinder #3. I hope the pic shows up in this post.
I spent most of the summer removing ALL the parts on this bike. I sure learned a lot by doing so. I'm going to continue to disassemble the engine so if you're looking for a used piston, I'll have 3 of them to sell. LOL
Now I'm going to see if I can get a pic of the ruined piston posted below.

Re: In need of engine diagnosis on '03LT

Yeah, that might cause a little bit of a problem. A borescope could have helped find that, but they can be pretty pricey. Out of curiosity, how do the other pistons and cylinders look like they're holding up? what about the valves and seats on that cylinder? One would think they should have taken some beating as well.
Are you going to re-ring all four pistons? With that kind of mileage, you might as well, along with honing the cylinder walls. It's an easy enough process. Happy wrenching Vern.

No honing these walls as they are Nikasil coated. If there are no scratches just install a new piston and rings.

Gonna part it out instead of fixing it.

Next thing to do is to pour kerosene in the intake port of the head to see if anything leaks past the valves. That chunk probably got chewed up into little peices before going out the exhaust as the top of the piston and the area around the vales is shinny. I did run it about 30 miles on 3 cylinders.
The reason for not fixing it is because I figured I'd spend more doing all that should be fixed than I would getting another bike. Also I didn't loose any riding time this summer. When one is 73 years old , time is a factor and I couldn't afford a dealer to fix it anyway. I'm pretty slow at mechanican. LOL
The other 3 pistons are good when adding new rings, in my opinion. I figure someone on Ebay might be looking for a piston as I see none listed here of late.

No mods to speak of and 89 octane most of the time.

I'm gonna have the mechanic at Engels BMW in Kansas City give me his opinoin as to the cause of the fractured piston. It'll be as good a guess as mine, I suspect. LOL

Due to heart health, the Dr says not to ride under 40 degree air temp. Ugh! Now it is harder to get my 18000 miles a year in just in the summer. Guess that stopped my 20 degree rides now.

I noticed NO scratches/grooves on the cylinder walls, so guess all the wear is on the rings as compression in the other 3 pistons were low. So if I was gonna fix it I'd do a complete overhaul. Another reason to buy another bike to ride.
I noticed that the timing chain guide needed changing sometime ago and it was wearing a shiny place on the end of the head.

The reason I was asking is on two bikes I have seen fractured piston ring lands and they has cut the brown wire and disconnected the air box temp sensor. Also ran regular fuel so it left them wide open for detonation damage to the pistons. I want to find some one with the same issue that ran premium fuel always and did no fuel map mods. I don't think I will ever see that.

I just hear so many say "I run regular just fine and have to problems, until..."

93 octane isn't available close to where I live/ride, but it got a taste of it on trips. The brown wire is on Ebay as I write so it was never cut and the air temp was never unhooked. The bike did have 8700 miles on it when I got it though.
I did hot rod it a lot running right up to redline most days at some time or orther. Oil was changed every 3000 with 20-50 BMW oil. Never idled to warm up. I did add a can of stop leak that sealed the rear oil seal at about 100,000 miles. That stuff isn't supposed to damage metal parts though.
Maybe I just got the engine with the lemon piston.

Re: In need of engine diagnosis on '03LT

I know what you mean on stations. I about ran out of gas on 60 trying to get to Dexter, could not find a "name brand" gas station on my way back from CCR last week. Glad I was carrying a spare gallon on the Bushtec

Re: In need of engine diagnosis on '03LT

Vern, thanks for posting the update. Always fun to read through - although your problems are not fun.
Looking at the picture you posted, can you or anyone tell if that started as a crack/fracture, or is it burned?
Probably hard to identify now. I'm sure than if it started as a crack, it would have burned the edges anyway. Just curious.

The pic shows the break on the side, but when the engine was in the bike it would be on the bottom face of the piston. The chunk got pounded around in the cylinder enough to really shine up the bottom of the head around the valves and the top of the piston. Not a sign of soot in there anywhere. It didn't damage the valves at all as I poured kerosene in the intake port of the head and let it set all night last night and about a teaspon full of kerosene leaked past the valves. According to Clymer, that's a good sign that the valves are sealing OK. Especially since there is 150,000 miles on the valves.
I'm hoping the dealer mechanic has a idea as to the cause and what might have happened. I've overhauled farm tractors(top engine RPM may have been 2200) and I've never seen a piston look like this one. BUT, I really doubt it'd be a BURNED fracture. Just guessing though.
Someone is going to get a decent head for a cheap price when I get it listed on Ebay.
Here is a pic of the valves in the head.
