I just got done watch your video on brake flush, so I might be hitting you up for some answers to my questions! The ethanol gas that went bad in the tank did a number on the fuel pump and components so looking for parts to order. Nice to be back!

Yeah that ethanol is a bummer.

Dropped in a new Odyssey battery today. The one I bought about 16 months ago died on me and wouldn't hold a charge. It would show good voltage but it wouldn't hold the amperage. I got a warranty replacement from Batteries Plus at no charge. I hope this second one last longer than the first.

Today I finally took the time to flush my clutch line and wow, what a difference. Ever since I got my bike two years ago my clutch has never felt just right. It seemed to me that the last third of travel on the clutch lever was the only portion of clutch lever travel that had any effect on the clutch. The clutch felt a little "squishy" too.
Now with the fresh brake fluid the clutch engages after about a third of lever travel and is fully engaged after two thirds of travel. It feels a lot crisper and no longer feels squishy.

I'm gonna have to re-learn the clutch though, it definitely rides differently. In fact I killed the motor on the test drive lol.

Took a 100 mile first ride of the year and shakedown cruise for an upcoming trip to Big Bend, TX. It isn’t often that PA hits 74 degrees in March. The LT fired up as though it had run just yesterday and ran great. Changed oil upon return and a few more checks and a bath and it will be ready to head west next week.
Well, my LT ride to Big Bend didn’t happen, but I will give details in a separate post and not clutter this thread.

Well I finally got the bike all buttoned up again after fixing the instrument cluster. I checked all the fluids, especially the ABS reservoirs. All looked good.
I haven't ridden for about 3 months due to family issues, the weather, and having to fix the instruments.
So off I go today for just a short ride to the next village of Samford. It's only a few minutes down the road. I usually like to ride out there to get the Sunday paper and other small items ( like six packs).
On the way back on a flat section of road doing about 80 KPH the dreaded red triangle came up accompanied by the brake fail flashing fast. I tried the brakes and they were still there but after a while became the weak and scary excuse for residual braking that BMW thinks is fair enough. I was only a few minutes from home so I rode carefully home and parked it.
I put it up on the stand and with the engine still off I turned the ignition on. I head the usual sound of the ABS activate. I tried the front brake and heard the ABS motor whirring away, all good.
I then tried the foot brake and no sound. I turned it off and left it. Came back later and now I have the sound of both circuits working. I have full levels in all reservoirs.
On the way back home I stopped the bike and restarted it. The drive away test was all good but again a few minutes later without touching brakes at all the fail lights came back up in the same pattern.
Solid triangle with brake fail flashing at what I assume is 4 flashes per second. ( At least one brake circuit (front, rear , or both ) is operating in residual braking function mode.
It is exactly 12 months since I last flushed the system. I have checked the moisture content and the Dot 4 in the ABS module is showing signs of high moisture content.
My plan at the moment is to jack the connection to the ABS and clean the contact pins. I will also flush the system as it is due. With any luck I'll be back in business.
I had this happen a year ago and after flushing the system it was good up until now.
If these bikes didn't ride so great we would push them over a cliff.

Double check the brake switch set up at the pedal. This system does funny things if that switch is signaling "brake lights" without any pressure at the ABS unit can cause a fault as well. You should be able to move the pedal quite a bit before the lever on the switch makes (or rather breaks) the connection.

Just finished fixing my EHCS after it failed last year in a ride to Big Bend. No interest in spending $$$ a dealer so bought a new $27 scooter motor and replaced the old motor after removing. Of course I co rubies to ride while waiting on part and lost the two prices that hold the hydraulic rod. Had to wait on those $40 parts and work kept getting in the way. Got it all put back together (snapping that plug back in is a &$!/€|) and the center stand came back to life.

now onto to my spiegler brake line replacement and new pads. Doesn’t seem too daunting with all the videos out.

Thanks for the tip John. I did check it and the travel on the switch was fine. I flushed the system and I found the fluid very badly contaminated with water. I did the same flush exactly 12 months ago.

Just thought I would start a sticky to just see what is happening in the LT world.

Jean and I got out for a breakfast run and two hour ride in the Tennessee hills above Alabama. This is the first time we have been out since before my surgery on the left thumb July 13th. It felt really good to get out and ride again on the LT.

John. What surgery did you have done? I have an issue with my right thumb. Where thumb meets the hand it's bone on bone. Got Gel injection twice. Doc says wait till retirement to have surgery done

I had the same thing in both hands, trapezia bone essentially gone. The procedure was arthroplasty, they remove (what's left) of the trapezia bone and harvest part of a tendon to use to secure the base of the thumb. Then ball up the remaining tendon and place it in the pocket where the bone was.

Had the right hand done in June of 2016 and went very well. I had the left hand done in July of 2021. I was still working when I had the first one done. Post op you are in a wrap and brace for 10-15 days then stiches removed and a hard cast is worn for 3 weeks. Very glad I finally had the second one done. Depending what you do for work will help you decide. I did mostly office type work so it was easy for me.

John just wondering what causes that kind of injury. It wouldn't be excessive LT wrenching would it ?

Not surprising with all the bloody rain we've all had on the east coast (Oz) over the last few months!

Yes I've formed an opinion that the drain on the ABS system has the effect of allowing moisture to be absorbed into the ABS reservoirs. When you consider that in 12 months my bike had only done 2,540 gentle kilometers I find it amazing that they put these systems on a bike. It's a bit like betting your life on a WW2 vintage army surplus parachute every time you ride. I'm seriously thinking about deleting mine.

OMG !! - clutch flush and new fluid - completely different bike - can't believe what a difference that has made to the clutch operation - I don't think it had ever been done before. Also took the time to disassemble, clean and grease the gear shift linkage - again never been touched in the life of the motorcycle. Thanks to this forum and youtube this bike is coming back to it's former glory and correct operation ! New Wilbers shock for the rear due this week.

Hope you have better luck with it than I have had so far.I got a whole 600 miles out of mine before I got the same thing.I've spent numerous hours flushing and testing everything to no avail.The module is on my bench torn apart as we speak and no apparent smoking gun.

I repaired the speedometer feedback wire that was put on at the factory to tight at brake upper mount zip tie. Now I will have cruise control and other features on the ECU feedback, Thanks to all here for the posts to fix. Easiest troubleshooting ever. Next will be brake lines they look original. Any part numbers to share? Then rear speakers front are fine but back crackle bad even with fade to front.
