has any one got a guide how to service the stock damper on a 05.
and what the best oil is to put in?

Remove big screw on the end. It is an odd size metric allen, like a 7mm. Don't bother with the 2 smaller ones. Use the heaviest fork oil you can find, 15wt or so. Best improvement you can do for the least amount of money. After refilling work piston back and forth slowly to remove all air, then reinstall the plug you removed.
What would stock oil weight be? I like the stock feel. I don't want it any tighter but I'm pretty sure I have air in there.
If you don't want any more dampening then remove the unit from the bike; hold it on its end and remove the screw; work the piston, very slowly or you will empty all the fluid, to make sure you do not have any air trapped and then top it off with WD-40. We are only talking a few drops. The stock fluid it about the vescosity of water, don't know the exact weight.
that will work also. Just trying to save you time and money. I'm sure you have WD at your house. If you are going to the cycle shop might I suggest you buy the heavier oil, you want be sorry. You'll spend around $9 for the quart plus your time and fuel to get there. It's a shame not get a benefit for your time. My 2cents.
Thanks for the info PiedmontF350,
So if I understand correctly, you say that I take out the big allen nut.Emty all oil out.put in new oil til it overflows out the top.move a couple of times to get out all air and put nut back ?
(Yip, Capetown is a lovely place.I live inland, 20 miles north of Johannesburg.Inlaws are down in the cape and always go down there for the holidays)

You got it. Tell your inlaws to eat at a steak house named Hussars. It is on Main road in Rondeboush, it is just after the Baxter theater. They have the best Warthog ribs I have ever tasted. If they go on a weekend they will need reservations. It is a very small place and excellent food. I became friends with the manager there. His name is Craig, if he is still there have them tell him that an American named Chip sent them and that he stills wants the sauce recipe. Make sure one of them orders the warthog it is worth the short trip from any place in the cape town area.
I put in a F uchs 7.5 weight fork oil and woah!!! there's a big difference in feel. Quite a bit harder but at the same time much much smoother operation. I'll run with it and see if I want to go down to a 5 weight oil instead.
I was surprised at how easy it was to get all the bubbles out. Stock there were so many bubbles in the system
FYI it does require a 7mm allen head socket.

I have 10w in it now but I am going to try 5w next as it is a little firm. Make sure to top off the oil so you eliminate the freeplay of the stock unit.
Tried this today..... Filled damper with 5W fork-oil, right to the top and then bled it.
Went out for a ride these are my conclusions!
Heavier feel to steering at walking pace up to around 30 mph. (I'm sure I will soon get used to this however).
Drops in to corners with greater tracking and holds desired line MUCH better.
At high speed, 100 to 140 in sweepers the bike feels much more predictable and stable and tempts you to go faster still.
No longer shakes it head when front off the ground under hard acceleration.
(The only Bike I've ridden that was worse than the R-1 for this was the first ZX-10R).
All in all I would say much, much better and well worth doing.
I don't think I would want to go with heavier than 5W oil for the street though, would make town work just to much like hard work!
Since I'd got the damper off I thought i'd try to make it look a little more attractive, I've always disliked the look of the thing!
First I sprayed it gold but soon decided I didn't like the look so I set to it with wet 'n dry and took it back to the alloy and then polished it with autosol.
Looks great now especially on the bike.
I would recommend this to anyone who has been maybe thinking of improving the stock damper without the expense of an Ohlins or whatever.......
Asd an aside, I've recently been running my rear Dunlop Qualifier at 38lbs p.s.i. and again this is shed-loads better than it was at 42 p.s.i. as recommended.

Thanks a lot jmacf14.
So basically this is what I need to do:
-Remove the plug
-Remove the stock oil (DO I NEED TO WORK THE PISTON TO LET ALL THE OIL OUT?)
-Fill up to the top with desired oil (5W will be my choice)
-Work the piston SLOWLY to let all the air out until no more bubbles show up.
-Reinstall the plug.
Is that it or am I missing something?

thats about it, I did work the piston to remove all oil. One problem I encoumtered was the o-ring on the plug. after being exposed to the air , it stretched and wouldn't fit properly, but I found some replacements at car quest for 35 cents. But I also tried 10 wt first, didn't like it, then went to 5 wt. So I had mine apart a few times before I had the problem. If you only do it once, you shouldn't have a problem. Good luck. Also, I had to add a little more oil after working the piston, but don't fill it to the top, it will just squirt out when you put the plug in.
Are the only two options 5wt/10wt? I had an Ohlins before on my R6 and I had it set to 15 at all times. I don't like a lot of free play in the steering so what would you guys recommend I do? Do they sell a 7wt?
I put 5wt in mine yesterday and it feels 50% stiffer in hand but not much of a difference on the bike.. I may go up to 7.5wt or just get an Ohlins.
i used a 60mL syringe to inject the fork oil. pull out the two small allen key bolts and work the ram to purge the old oil. The tip of the 60mL syringe will seat perfectly with the inlet so that no air gets in. Pull the ram to the bottom of its travel, when you inject the fresh oil in this will push the ram to the top of its travel at which point oil will begin to well up out of the top drain plug. Suck a mL or 2 back out to leave an air bubble and screw it back together.
