Fs: 2001 r1100s
 
Hello,
Im a long time Pelican on the Porsche side, and a fellow Pelican directed me to this forum.
I own a 2001 R1100S in great cosmetic condition. 3 days ago it was my daily rider in FL, until what i suspect the transmission went bad. The bike starts, but when i put it into gear it does not engage and transmission makes noise. I thought its the transmission but someone mentioned on the forum its the input shaft. I have no idea. Im in the dilemma and decided to sell it or part it out possibly. I have the side bags, high case. 46,290 mileage

If someone is interested in bike as is with or without the bags, let me know.

Also, if someone can suggest what the poroblem may be,
Perhaps its not as bad as it seems. I have heard the input shaft breaking is a common problem with this model. Maybe i can fix it

Great bike overall, many upgrades like new seat, new tires, new brakes. Rwmua exhaust

Here is the ebay link:

the ebay link is for a transmission,
where is it located
what are you asking as is?

Sorry to hear that, man. Sounds like you have an input shaft spline failure. It's a huge systemic problem with the six-speed oilhead transmission. (Note: Someone will pipe up in a few minutes claiming it's overblown and actually quite rare, despite the literally dozens of occurrences on this tiny corner of the internet. It's NOT overblown and it's actually quite common.) If you repair the transmission it will happen again in another 46K miles. Your best bet if you want to repair it is to buy a known-good used transmission and a clutch disk with an extended hub. You can probably fix it for $600-$700 worth of parts. It takes some tools and a bit of mechanical skill, but it's not unpossible.

Where in FL?

Plenty of threads here on the forum, and more importantly, help from others who've done it, to guide you through the disassembly, repair and reassembly, should you choose to fix it. It's not that difficult. A bit time-consuming for a novice, but doable.

Im in Stuart, FL (30 min from West Palm Beach)
I found a good used transmission for $500. But dont have the time or desire to try and swap the trannys. Its a shame because the bike ran perfect.

Why not look into having it done by a reputable shop? A highly qualified independent repair facility may be the way to go. And I agree it is an input shaft failure.

lada03 08-14-2018 08:28 AM

I think its time to move on. I enjoyed the bike, it was good to me.

I have neglected my 911SC, will be driving that more often

JimMoore 08-14-2018 09:38 AM

Well, good luck with the sale. You may reconsider after you find out how much you can get for it. They are interesting bikes, but they were never big sellers and the used market for them is extremely soft. I doubt you can get more than a grand for it in its current condition.

lada03 08-14-2018 11:23 AM

Thanks. Would hope this bike will go to the right guy who can fix it and enjoy it

sgoodwin 08-14-2018 11:49 AM

I saw your add on craigslist yesterday & thought spline failure not trans. It's a fairly involved repair & think your price was too high for that kind of repair. I realize your bike is otherwise in good shape but still too much money. This is the kind of investment you make when you want to keep it because they're not selling for much if any above what you want in running condition.

lada03 08-14-2018 12:31 PM

I realize my asking price is a bit high, but given the 90% lowballers on Craigslist, i gave myself some room to negotiate the price

sgoodwin 08-14-2018 12:45 PM

Best of luck with the sale. I'd fix it myself, just a clutch replacement was quoted over a grand years ago not including ripping open & replacing the trans shaft, seals etc. The other option is to part it out, possibly the most money to be made. Sort of a dilemma with the bike being worth what it is.

Alfa145V6 08-14-2018 12:49 PM

It’s far too nice to part out. I would like to have a project like this but I’m on the wrong side of the pond.
Sorry to go off thread, but if Jim sees this, why did you say this? “If you repair the transmission it will happen again in another 46K miles.“
Does that mean that the new replacement output shaft is still of poor quality?
I assumed that if/when mine goes I would replace the shaft and clutch (with the modified disc) and everything would be fine from then on. Why aren’t the replacement shafts made from better material as BMW must be aware of the failed ones.
If the answer is something to do with being ‘off centre’ then I will be truly stumped as I couldn’t follow that discussion years ago and it boiled my brain!

sgoodwin 08-14-2018 01:01 PM

I agree, I wouldn't part it out but some farkles are still pricey plus lots of good parts.
Yes the off center thing can come back to bite you but the longer clutch spline helps it last longer. Unfortunately though the clutch plates are Chinese manufacture & of unknown durability. I think the clutch hub made by a member here was a better idea as it could be adapted to different clutch plates.

Oh & BMW don't give a damn about no spline shafts.

There is some debate about the underlying cause of the problem, but a majority of people think it's due to a misalignment of the transmission. In many cases, mine included, the owner has spent thousands of dollars repairing a transmission only to have the same thing happen again at the next mileage period. So simply replacing the input shaft and clutch disk will not work in many (most?) cases.

There have been some success stories. There was a guy who measured the misalignment and created some offset dowels to replace the alignment dowels. that seemed to work for him. Other people have used a clutch disk with a longer hub. That seems to be working for a few people, but the original misalignment is still there. IMO your safest bet is to find a used transmission with good input splines. The fact that it's used and the splines are good means (hopefully) that the transmission was built correctly and there is no misalignment. Even so, I'd spend the money to get a disk with the longer hub.

lada03 08-14-2018 03:14 PM

These guys would do
$500 shipped for a working transmission if you buy directly

sgoodwin 08-14-2018 04:17 PM

Looks good, those shafts look like new, I don't see any wear showing usage, rebuilt? Also wonder why the casing is beat up on the output side. Might ask them about it. Otherwise it seems a solid deal. That & a clutch makes it go again. As Jim says go for the longer clutch hub disc.

lada03 08-14-2018 05:06 PM

It came from an insurance company. They said the Bike was in an accident but it was tested

lada03 08-15-2018 11:40 AM

If i dont get $2200 for it, I will be parting it out

Bags $500
Seat cover $50
Rapid dog Bar raisers $150
Wunderlich center Stand $150
Extra helmet
Tires new
