rear shock for big guy

Hi - not sure if I posted my topic properly...so here goes..apologies
if it's a double up. Last year I rode from Magadan (Siberia) to
Istanbul on my KLR650. 20,000kms in 100 days (see
www.users.bigpond.net.au/AdrianScott for details). I had
many "mechanical challenges" which I learnt a lot from, but one thing I
noticed was that the stock rear shock tended to bottom out a lot...I am
six feet eight and 250 lbs and my bike was loaded with about the same
in luggage again and I suspect it struggled under all that weight. I
am planning another trip and even in riding around near my home the
bikes sags a lot...I've got all the settings as hard as they will go
and was wondering whether an aftermarket shock would make much
difference? Any advice greatly appreciated.
Thanks,
Adrian Scott

Adrian--
If you're 250 w/ 250 pounds of gear you're WAY
overloading the poor beast. What are you carrying, an
anvil? No wonder you had mechanical challenges.
Seriously though, yes, a different rear shock will
make a huge difference. Check out the KLR FAQ (linked
at the bottom of this, and all, list emails) but
basically you have a few options:
1. Raising links, which physically raise the bike and
increase the shock's leverage against the swingarm
($75)
2. Installing a stiffer spring and/or heavier oil onto
a stock shock ($80-$125)
3. Buying a Progressive Suspension aftermarket shock
($400)
4. Getting a F1 shock (they make the shock for the
military KLR) $475
4. Getting a nice unit built for you by Works
Performance or similar ($500-$600+)
With you and your gear, the bike should sag about 3"
in the rear (from full extension, ie, wheel in the
air):
http://www.4strokes.com/tech/racesag.asp explains it
simply, but note that KLRs want 3", not 4", of sag.
I haven't run the progressive shock myself, but I've
seen them fail numerous ways and wouldn't spend the
money. To my wallet, in for a penny in for a
pound--if I'm going to spend more than simply
refurbishing the stocker, I want it done right. A
consideration unique to your intended usage, too, is
that ONLY Progressive can rebuild their shock. If you
blow a seal in outer hockawackastan you'll have to
mail the whole damn thing to Progressive. With most
of the other options a decent moto shop could help
you out... worst case you have a part or seal shipped
to a future destination and ride there with no
damping, but at least you keep the shock. Having said
that, a lot of listers have and are happy with
progressive shocks.
I'm in the process of refurbishing a stock shock,
myself.
Good luck.

I'm at 280, with eagle mike r1 raising links the sag is 3" when cranked
to 5 on the preload. I'd reccomend a stiffer spring for that kind of
load.

I'm at 240 and used to carry about 50 lbs of camping/etc gear on
really ruff roads. I went to a 425 LR spring in the rear,
Progressive in the front with the recomended spacer cut down an
extra 1/2" which made it a little softer on the harsh lines, etc.
Also filled with 10 weight oil. 14 tooth rear sprocket really eases
the load on the engine in bad terrain and would surely help in your
situation.
By the way guys, my '00 KLR has just seen the 3 bike join it in the
garage since I've had it. A new '06 DL1000 which replaced the '02
R1150GSa.

It sounds like some additional preparation might help you before your next trip. Have you done the basic KLR modifications like bowl vent "T" mod; safety switch by-pass (in the form of a carried jumper, or, permanent by-pass, or a by-pass switch- my preference) as this one seemed to have caused you a problem in China; replace the fuses with sealed ATO fuses relocated to be accessible without removing the seat; packing all wiring plugs with silicone dielectric grease or spraying with ignition sealer, etc.?
Do you plan to use the same bike for the next trip?
I recognize that you have a life outside answering my questions (VBG) but would very much like to hear more about how the bike performed, problems and how you resolved them. You size likely was an advantage for horsing the KLR through mud holes but would have been against you due to the extra load. Too bad you're in Oz as it would be a pleasure to give you a hand with preparation for the next run. It is better than nothing to live vicariously through someone we know.
How can we help you to get ready?

Thanks guys. I didn't know about the raising links. Do they raise the
seat height? Also, I have installed a centre stand and wondered whether
they might change the way the bike sits on the stand?
Appreciate your tips! Thanks
Adrian

They do raise the seat height some, perhaps 2 inches?

Adrian--
Mike's raising links will raise the seat height.
IIRC, the RL1s raise things by 1 1/2", but that's
strictly from memory. Keep in mind, though, that with
~500lbs on the poor thing you're WAYYYYY squatted
down. If the RL1s manage to get you up to proper
sag, you'll be 1 1/2" (or whatever it is) above where
the bike normally OUGHT to sit, which is probably
already several (yes) inches above where your loaded
bike rests. I think you are a prime candidate for a
stiffer spring as Devon suggested. Or maybe both.
