Just thought i'd start a new thread.
Seems most if not all posts on here are for the older (pre 05 LT's). Does that mean that the 05 thru 09 didn't have as many issues as the earlier ones. Personally, I bought an 06 with 68k miles on her, and couldn't be happier. It seems the previous owner took very good care of it. I've had absolutely 0 problems with it, and have put on more than 15k in 6 months of riding. Would like to hear other members experiences with the post 05's. From what i see, they are a completely different bike compared to the earlier ones. I know there are still many many LT riders out there with the newer models, let's hear your experiences.

At least that's my perception.

Have had my "09" since new. Had 14 miles on it when I got it..

Only problem was the final drive just died with 57k on the odometer.

No other problems...

I don't understand all these final drive failures. I'm paranoid about it, but don't really know what to do about it. My 06 has 70k on it, and the final drive seems fine.. When i change the oil, i check the plug for any metal, but that's all i can figure what to do. I was under the impression that the newer LTs didn't have that problem as much as the older ones.

Although the early LT's had more failures than the later years all years have had some failures. BMW used this style final drive for about 20 years & had some failures on all of the models it was used on. The heavy LT finally made the failure rate unacceptable. Most of the LT's built in the later years had a closer factory preload spec. but not all. I just boxed up my 85th rebuild final drive to ship back to the owner. I have seen some 2008 LT's with 3 times the allowed factory preload. I have rebuilt one failed 2008 LT final drive that had less than 10,000 miles on it.

I bought an 05 in March. Had 39,000 miles on it. I took it to Kirk Johnson to do comprehensive and preventive maintenance on her. The only components that needed fixed or replaced were my O2 sensor and electric hydraulic stand. Other than that; everything is in fine shape, including the stereo (fingers crossed).

Just on 11 years ownership of my '05 LT since new now (Sept 2005).
While its an '05 model, it was built 04/2004, so sat in a warehouse for about 16-17 months before I got it.
Currently at 112 thousand km.
It's had 2 x new clutches, on its 2nd rear rotor, and 2nd front rotors.
Final drive was replaced with a near-new one off a 2007 LT (1200 km) that had been triked, not because of failure but because its seemed to be a smart thing to do when swapping out the clutch last time at about 100k km.
Hadn't been riding it much lately as I got a K12GT (2005) to commute on and save the LT, but a taxi tried to take it (and me) out a couple of weeks ago, so while its in waiting for new panels and parts, the LT is getting to breathe again. Took a little while to get the feel of it again, but starting to have a blast, even in city traffic. So comfortable to ride on compared to just about any other bike I've been on.
Many good miles (km) left in her yet!

At least that's my perception.

I bought my LT new in June 2007. It is the most comfortable, most sophisticated and best performing bike I have owned. It is also the most expensive, most maintenance intensive and most troublesome.

My big failures have been final drive pinion seal, final drive pivot bearings, leaking transmission seals that took out the clutch, and failed u-hose on the fuel pump that technically left me stranded. I say technically, because it happened in my driveway just 1/4 mile from my garage. God was looking out for me as this happened the morning after we returned from a 5,000 mile ride to Newfoundland!

However, I have done extensive, expensive modifications to prevent failure: Jiffy Tite QDs, FIBIB trunk latch kit, etc. After I found the service bulletin on the squealing rear brake, the dealer replaced the rotor with the new style, but it is back to squealing occasionally. I also was plagued for years with an off-idle sag/hesitation that was very annoying and dangerous in heavy traffic. I am not sure the cause, but something I did during the clutch repair seems to have fixed it. Maybe it was the oxygen sensor, maybe it was the thorough TB cleaning, but my best guess is it was a vacuum leak in the canister vacuum line given its periodic nature (I suspect correlated to pulse valve actuation). I eliminated the pulse valve and simply interconnected the vacuum ports as is standard on the non-US bikes (thanks for that idea Sailor).

My biggest complaint of all is the dealer network. They are sparse and my nearest one, Country Rode Motowerks in Rochester, NY, poked me in the eye on a service request after I had spent $25K with them on LT, clothing and initial service visits. So, I now do all my own work including the recent clutch repair. If I buy another BMW, and that is not a high probability, I will try Kissell in State College, PA. They aren't much farther away and I have heard good things about them.

If the later model LTs are more reliable than the early models, then early models must have been atrocious! I suspect the reason is simply that the older models are, well, older and the age and mileage simply means they require more attention.

My only real apples-to-apples comparison point is my 1987 Kawasaki Voyager XII. It was far less expensive than my LT, less troublesome (never had a failure that could have stranded me), far less maintenance and with a closer and much better dealer. However, it lacked the features and performance of the LT.

Q: When you removed the pulse valve, I assume that you simply unplugged & stowed the connector, and there was no effect on the ECU. (the ECU doesn't monitor the valve?)

Did you put a cap on the "T" that goes to the valve, & leave the vacuum "spider" in place?

(2000 K1200LT, 56,000 miles.. no failures (except broken cruise control cable).

I didn't remove the valve physically, just removed it from the loop. I left all original parts and just plugged the short hose that connected to the T in the manifold and replaced the T fitting with a length of hose.

To answer your Questions:
(1) the ECU sends command the pulse valve so it opens up (at intervalls), BUT it does not monitor and will not trigger a fault.

(2) All K1200LT/RS sold in Europe and Canada do not have this pulse-valve, so the spare loose connector is just attached to the fuel-rail with a tie wrap.

(3) When pulse valve is not installed, the middle vacuum hose (with the white plastic "T" junction) does not exist, so the middle vacuum hose is a single longer hose to join the the other futher side plastic junctions. Just go to any auto-parts store with white plastic junction to find a correct size hose so you can replace the 2 short sections with only one.

It is possible to find a rubber cap that will block the end of this "T" plastic junction, BUT why bother adding parts (more failure point) when you can simplify the design...

That's good info!
Thanks!!

The reason for the question is that, when I was performing a throttle sync (with a carbtune),
the pulse valve was in the way.
since I'm not using it for anything, I considered removing it & stowing the connector, but I hesitated because I thought the ECU might get angry.

Next time I'm in there, I'll remove the valve & stow the connector.

(by the way.... the carbtune is the best synchronizing tool that I have used so far)

I've had three newish BMWs. Thank god I've yet to have a major issue. That said the previous BMW dealers in CT gave lackluster service. They're all gone now and Max BMW has shops in and around CT. I've been to three of them and have always been treated well. Their service is why I continue to buy BMWs even if they are 40-50 miles away.

I buy most of my parts from Max. I have no real complaints about Bob's, but Max just seems a little more responsive to technical questions. Nobody beats BBY for maintenance parts, although I am disappointed that they sell full sintered brake pads as being suitable for the LT rear brake.
