First start prep ?

You experienced engine builders, whattaya tink?

Getting ready for first start after my top end over haul.
New rings, valve job.

Wondering if someone has a suggestion on how to crank the engine without starting just to get the oil pump to flood the galleries before actually firing it up.

I've done a few engines before, and I always just started the engine right up, never had a problem. I've oiled everything during assembly but the camshaft galleries won't be full.

Can I just pull out the spark plugs and crank the engine for a while or can that damage the ignition system?

Or should I even bother?

On k1200RS, there is a loophole in the starter interlocks that will allow you to run starter without fuel or ignition - I often use this technique to exercise oil pump after long storage.
Because of reverse-gear electronics (part of starter interlocks), this might not work on K1200LT, but it will NOT do any harm - in worst case the starter button will do nothing:

(1) Park on center-stand
(2) Side-stand down
(3) shift in any gear (not neutral)
(4) Ignition ON (wait a few sec)
(5) Pull clutch lever fully, THEN press starter (while keeping clutch lever in)

Engine will not start but should turn over.

Thumbs up Re: First start prep ?

Charley I would pull the plugs and ground plugs to motor. Pull off the valve cover to look for oil being pumped up top. Once you have that your good to go.
Button her up and enjoy the next couple of 100K miles out of the bike !

Re: First start prep ?

If you filled the oil filter with oil before you installed it & with everything well lubed I would just start it. Warm not cold oil would help. If you don't have a heated garage then a heat lamp or equivalent will help to heat the oil.

Engine will not start. But will turn over. This will work on the LT after storing all winter huh?

Re: First start prep ?

Our race engines have external oil pumps and we can remove the drive belt & prime the engine before we start them. We also have heaters on the oil tank to preheat the oil. Every now & then we don't get a chance to preheat the oil & even though we primed the engine I can tell that it was started with cold oil when I rebuild it.

On the LT the starter will not turn if you are in gear, clutch in and the side stand is extended. I use this method at fuel stops to kill the engine in gear with the side stand. Occasionally I forget to raise the side stand after fueling and the bike will not crank. Raise the side stand and it fires right up and I drive away. Center stand has no affect.

John,
On occasion, to confirm side-stand switch is working in both direction, I use the same technique at fuel stops to kill engine (extend side stand in gear , engine dies , then turn key off).

However, in 2nd generation K1200RS (2002-2005 USA) there is a loophole in starter-interlocks - starter button will turn starter if you pull clutch lever, BUT it will never start (as fuel and/or ignition is cut by Motronic). Hence, I was curious if same would apply to 1st gen or 2nd gen K1200LT.

Re: First start prep ?

Curtis can pull fuse F4 and kill the ECU and Fuel Pump but allow cranking to build up oil pressure.

+1 for John's idea.
I just pull the fuel pump fuse and crank for 20 sec or so.
+1 for installing the oil filter pre filled too.

Happy riding

I am sure you put some assembly lube on the cam and did not install it dry. Just checking.

I didn't use any proprietary "assembly lube", I know there are some products which claim to have better retention for initial startup, didn't buy any of that stuff. I just used engine oil on all surfaces, every bearing and journal, crank, cam shafts, cam followers. Basically every moving surface had as much oil as the clearances would allow. (Good, old fashioned oil can).
And, yeah, the oil filter filled to the brim before installing; I always do that.
However, I know that the galleys in the camshafts drained somewhat, and I didn't make an effort to refill them before reinstalling. That's why I want to crank it a while before I put the ignition to it. I'm just hoping to have good oil pressure right off.

I'm also thinking of putting a squirt of engine oil in the spark plug holes. (Just to make it smoke more on start-up)

Re: First start prep ?

SitRep

Installed the gas tank, reconnected all electrical connections. Pulled spark plugs and rotated the crank 360 degrees just to be sure I didn't screw up the valve timing. If I had a valve/piston interference I wanted to find out by hand rotating things rather than finding out when I cranked the starter. (Yeah, I'm a worrywart).

Engines I have done: Volvo 122S, Datsun 280Z, BMW R75/5, R90S, R90/6; they all survived my rebuilds.

But there is always that start up anxiety. Back when I was building electronic stuff in my Ham Radio days, the last test was the "smoke test". Spend weeks soldering and bench testing circuits, but on the final day, plug it in. Wait for smoke. No smoke? Good.

First start on an engine rebuild has that kind of anxiety for me; I haven't done enough to have confidence.

Old joke: What is the essential ingredient in all electrical circuits? Ans. "Smoke".
Why, because whenever the smoke gets out, it doesn't work any more.
Class Charlie Fire! Commander!

Tomorrow, heat the oil pan, pull fuse #4 and crank it a while. Run an exhaust hose out under the garage door, then put in the fuse and see what happens. Look for leaks.

If you run a exhaust hose out the door you will have made all of that extra olive oil you put in the spark plug holes a waste of time.

Startup

Thanks for all the guidance during this project.

I started this AM.... brief problem: On first start up it wouldn't idle, ran rough, and needed blipping of the throttle to keep going. Quick check of faults with the GS-911 show TPS fault. Discovered I had failed to plug in the TPS. The plug for the TPS sensor had disappeared into the bowels of the frame so when I went about plugging everthing back in I missed it.
GPS-911 told me of the fault, so had to take the tank back off to search around for the problem. The plug was so tucked out of site it took me a few minutes to find it.

Engine now sounds fine, K-bike rattle well preserved and all.

Now to button the bike back up and wait for April. Unless we get a really good thaw and a rain that washes the salt of the roads, and clears my driveway of snow and ice, the bike will suckle on the battery tender until after sugaring season.

Thanks again for all the help from so many folks for all the suggestions along the way.

God job - I am sure you will sleep better now ;-)

I have done a lot of testing on these TB and I must say I am very surprised the engine would start with TPS not connected (although I never tried that case).

Are you sure it was not the TVA that was not connected ?

Yup, sure. The TVA has a connector in plain sight, that was easy to see during reconnection of things.
The TPS's connector on the sensor itself is on the bottom of the sensor assembly, not so obvious; and the connector coming from the harness was so tucked away I didn't see that either.

And the GS-911 showed TPS fault, not TVA fault.

Yeah, it started right up with the TPS disconnected. Needed a little extra throttle at the grip compared the usual cold start, and then needed "blipping" to stay running. It would not idle and would die immediately if the throttle was let go of.

Thanks! for the suggestions

Curtis,
Unknowingly you may have stumble upon a useful fact - let me explain:
Unlike many EFI systems in cars, on K1200 Motronic 2.4, the TPS is the only indication of air volume provided. There is no flowmeter (or MAP sensor) that takes pressure / throttle demand into account. The system must deduce air mass by combining TPS and RPM readings. Hence, I had always assumed the K1200 engine would NOT start or run without a TPS signal and never bother to test it.

Pretty cold here near Montreal and I hate to just start and do a partial warm up in garage. Next time it is warm enough for a ride, I plan to collect some "real-time" data log values with GS911 (with TPS disconnected). There might be some "limp-home" mode where Motronic takes only the RPM into account if there is no TPS values (RPM from Hall-effect sensor).

This could have certain implications to troubleshooting a defective TPS. Will keep the forum members updated with another more appropriate thread. Sorry for the hyjack ;-)

Although the quote (from my signature) does represent my thinking, I could not have formulated as eloquently as you did – it came from you. Even if I tried, I might have created something having linguistic interference from my French background ;-)

For those who are curious how the signature came about, see this older thread from 2011:
http://www.bmwlt.com/forums/k1200lt/...-rear-end.html

About the weather:
Not much difference between Montreal and Vermont in most seasons. I ride in Vermont every summer. In both places, winters are too long and too damn cold ;-)

Holy moly, LOL I said that?! I quoted you quoting me? Yikes! Can you spell Sinility?

You ride Vermont? Stop by here in the Deep South. Pick up some Maple Syrup....not much maple syrup in Quebec is there?


Addendum: for the flat landers reading here, it is a joke. Quebec is the world leader in maple syrup production.
Quick stats:
40,632,512 taps in the Province of Quebec in 2011 vs. 3,500,000 taps in Vermont in 2012

In terms of production, in 2010:
Province of Quebec, Canada: 7, 989,000 gallons harvested.
State of Vermont, USA: 890,000 gallons harvested.

Where ever you get your Maple, look for pure Maple Products. The most delicious sweetener there is. Hint: it isn't Log Cabin, or Vermont Maid

Re: First start prep ?

John, for what it's worth most if not all of the time a defective TPS will not show up on a car running an OBDII scan. It will set a code if unplugged like Curtis had. Interestingly, the MAP or MAF sensors do not necessarily set codes when unplugged, I think because the vehicle is in open loop mode when started and running strictly off temperature and RPM data. My many Taurus vehicles have all had me forget to plug in the MAF/MAP sensors and they didn't set the MIL light until several minutes of operation, presumable when the system went to closed loop mode and then was missing the proper signal.
Speculation on my part, but I think the engine control programs are designed to allow most of the individual engine management components to fail one at a time and still run. As you pointed out earlier, that's why it can be so tough to trouble shoot them. Many of the components will cause similar symptoms depending on the conditions present.

P.S. Damn, this has been an interesting thread.

My many Taurus vehicles have all had me forget to plug in the MAF/MAP sensors and they didn't set the MIL light until several minutes of operation, presumable when the system went to closed loop mode and then was missing the proper signal.
Speculation on my part, but I think the engine control programs are designed to allow most of the individual engine management components to fail one at a time and still run. As you pointed out earlier, that's why it can be so tough to trouble shoot them. Many of the components will cause similar symptoms depending on the conditions present.

P.S. Damn, this has been an interesting thread.
We are way off the original thread here - more hijack - sorry Curtis. Ok.. one last post as we need to start a new thread more specific to these issues.

Dean,
Knowing that the K1200 does NOT have anything to fall back on (like MAF or MAP), I did not believe that Curtis could have started it with TPS not connected. So there is more material for testing when I have time and warmer weather to ride it...

I don't think thread digression is a big deal. Kind of like a conversation which goes its own way. Keeping threads on topic may help in future searches, but then most folks don't use the search much anyway.
I always find in interesting when knowledgeable people contribute.

I've a basic understanding of electrical and electronics, but don't know much about modern internal combustion engine ignition systems, ECUs and the ilk. I'm a self taught, shade tree mechanic steeped in carburetors, points, and condensers. So any insight into all the sensors that feed the moronic (Motronic) computer is good info for me.
I don't know where I'd be if I couldn't plug in a GS-911. I don't use it much, but it is a handy tool.

I find following threads such as this very educational, however I disagree with "most folks don't use the search" I have used it a lot, and I believe anyone who is familiar with forum use will as well. However the search often fails to bring you to the information you are looking for even when you have read a thread in the past with said information. Thus people get tired of looking through unhelpful information and ask questions. Yes sometimes the information is easily found with the search, but I have spent many hours searching the forum not finding what I'm looking for only to then do an internet search using Google or Bing and find the information here, where vBulletin's search engine couldn't find it. I have seen some questions come up where the information is really easy to find, tire questions are a good example as there are several discussions on them every month, where it seems the poster was just to lazy to look. However what is the purpose of a technical forum if all we do is chastise people for asking a question just because it has been answered before?

How's that for a hijack! The troll masters will be proud!

Thanks for the offer, but I got the bike moved off the lift and from the garage to the barn.
Nice sunny day for it. Put down a little sand so I didn't even have to get out my chains.

Curtis,
Many who learn to fix their bike with simple carburetors think that Electronic-Fuel-Injection (EFI) is black-majic or just too complex. Obviously anyone who thinks like this has not worked on a modern 4 cylinders bike from last generation of carbs (around 1980s) when they where trying to make them more fuel-efficient (like a Yamaha venture V4).

If you had a single part not set or assembled properly on such complex 4 carbs system, you would still be working on it as I write this.

You have been able to change piston rings on your K1200LT without intricate knowledge of metallurgy although the designer of that engine had to know something about it. In the same way, you can troubleshoot and understand EFI without being able to know all the internal details to build such system. Some of the internals will remain a "black-box" - like the metallurgy analogy, that should not stop you from doing troubleshooting and some fixing - as long as you understand the limitations of your knowledge. Knowing all the internals is not often required (although I like to do some reverse engineering to better understand how it behaves).

Modern EFI are quite reliable - with some understanding AND simple troubleshooting tools like a GS911 (or an ODBII readers for your car) you can solve 95% of problems. Even with a Multimeter (Volts / Ohms) you can solve many problems on a simple Motronic EFI system - however a GS911 will get you there quicker with more data ;-)

On a modern 4 cylinders motorcycle, I will choose EFI anyday compare to some of these 4 carbs system. Some will argue you can fix these on the side of the road with simple tools. On a single or twin cylinder engine maybe you can... on these 1980s complex carbs for a 4 cylinders... good luck!

Re: First start prep ?

The first Bosch fuel injection back in late 60's was the same essentially as the LT fuel injection, same engine temp sensor, tps built into the throttle body, no knock sensor, no tva instead a 5th injector for cold start and of course it was solid state instead of micro processor. I was confused after having a K100 and K1100 which has/had air flow measurement built into the air box.
The early system on my VW (69) injected on 3 cylinders at once and the 4th at a separate time, it is interesting that on the LT they can inject all 4 at the same time.

Sweet! You make us all proud Curtis. I'm also enjoying my LT after referbishing it. It is like a whole new bike. Enjoy (when the weather cooperates).
