I paid 145 for a 6Ah 36v Bosch one so the pricing's quite similar (I did
have to search, a few places wanted over 200 quid).

Just got back after ~50 days, I'd disconnected the car and big bike battery
because they have clocks etc which would drain them over time. Reconnected they
both fired up first time, the little step-thru didn't bother nothing to drain
it, had to kick it over enthusiastically for 5 minutes or so but the battery was
fine, it has always been a sod to start if left > a week or so.

Stefan put a new one in. I just got home from a month+ of riding it
~3800 miles, and I never bothered to look to see what kind it was. Oh well.

OE battery is a Yuasa or Exide AGM[1] (absorbed glass mat) which is a
sealed for life, valve reguataed, lead acid battery.

[1] YTX14BS or YTZ14S after 2009.

Notes from a small island.

It's partially dismantled now and off to Oxford next week for its safety
recall work. Parts are on their way to fix the fuel gauge and then if I
can get the paperwork sorted with a bit of luck I may be able to have a
ride on it before the end of the year.

I found from its VIN that one of its options is "lowered seat" - did you
know that?

No, not at all. I kinda doubt it, especially considering how much work I

Fnaar. There are a bunch of other options that I'm trying to work what
they mean. I don't know what lowering the seat entails, suspension maybe.

low seat just means the same seat pan with less foam

the BMW part embossed on the seat pan will be the same on each bike. The
actual finished seat part no. is on a sticker that has probably fallen
off by now.

Lowered suspension will be listed separately.

I have a lowered suspension S1000XR and the VIN decode says:

X0776 Driver's Seat Low [1]
X0499 Lowering

Actually, the OEM (for my '07) is a YUASA GT14B4. The -BS batteries are
similar but "BS" suffix means "bottle supplied" according the friendly
parts guy at the Yamaha dealer, and this means you have to fill and seal
the dry charged battery yourself and give it an initial charge. I figure
the factory sealed ones might last longer...

I've just bought the OEM factory sealed unit from partzilla.com. $133.75
including tax & shipping.

You may know...

My 2003 BMW 1150GSA is lowered and a royal PITA to get on the
centrestand.

I'm guessing it's aftermarket and would be - probably - Touratech.
What do the kits consist of?

The PO had it from 18 months old and rode it from Alaska to Argentina
and did not penny pinch
on it.

It's dripping in Touratech parts, Wilbers shocks etc. The last service
at 171K was done by the main dealer.

Poor bloke had a stroke and couldn't ride it anymore so I had it off
him.

Anyway, question is - how do I unlower it and would those parts have
any value?

we don't have any bottle supplied batteries at retail now as battery
acid is no longer retailed. I imagine they are still made but have to be
filled by the wholesaler.

I have not heard of any anecdotal evidence to support your hypothesis
about longevity.

open a thread at UKGSer as I had a quick look and there seems to be a
number of bodg^^^^adjustments mentioned from shorter springs to shorter
shocks.

there's a separate section for the oilhead 1100/1150

you should be able to access that section and search the threads without

I bought a new battery last year online here, came with the separate bottle of
acid. Less nanny state I guess.

Thanks, indeed it does seem to be just thinner seat foam for around 30mm
lower.

Further decoding of the VIN reveals it's got ESA suspension which I
suspects = expensive bills to replace or refurbish the shocks if
required. Am I right in thinking it just adjusts the preload, or does it
change the damping instead/also?

What year is the bike? I can't remember how sophisticated the ESA system
was on earlier bikes.

I have ESA on my bikes, both 2016. I can adjust preload - the engine has
to be running but stationary. 3 settings indicated by little graphics of
a head and suitcase. 1 head, 1 head + luggage, 2 heads.
I can adjust damping whilst riding. The GS will have extra options but I
can choose a softer, foxed damping "road" mode or the "dynamic" mode
that adjusts the suspension on the fly. The GS will have an off road
mode.

As for repairs, there are a couple of companies that will refurbish the
ESA units. Again, UKGSer will provide details if needed. They seem quite
robust as I don't read about many failures.

Didn't Ogden have a failure on his S1000?

He did, about two days after the warranty expired.

No problems since it was replaced though. I've still got the faulty original, having intended to return it and still it. Surprise surprise, I never did.

I think that might be a similar vintage to the one Krusty bought so I am

like the ABS & TCS, the sensors don't communicate with the ECU until your
moving. Perhaps, if you are lucky, as the bike spent most of its life
hibernating, the sensors will have gone into deep sleep mode. Turby wasn't
moaning about a warning light in France, just the fuel gauge.
