Anyway, aftermarket parts that I know of include

Akrapovic Exhaust (music to my ears!)
Acerbis Tank
Emig Racing Steering Stabilizer
High fender conversion
Single front disk brake
After market skid plate with tool box and water tank
Canister and emissions crap MIA
Came with 16 / 45 sprockets (hated combo, way too low)
Now running 17 / 42, which I like much better (now cars are not blurry in mirrors)

Bike back fires letting off gas and runs rough at low rpm, which I'm assuming is due to stock jetting. Thus, my next upgrade is to jet appropriately for less restricted air box and exhaust. Starting to research best combo. Any suggestions would be helpful. I also have a minor oil leak and the rear shock linkage is loose. As far as I can tell, it's the bearing with grease fitting so I will try replacing to see if that fixes problem.

Love this bike, especially with new gearing. Hoping it gets even better with jetting. Rear tire is already more that half consumed. I live in Colorado and have been riding a mix of highway, dirt roads and trials. Any suggestions on a good dual sport tire would be helpful as well. Seems like the knobby that came with bike is over kill for the dryer type trails I've traveled on so far. My last dirt bike was a 1984 XL350R, which strangely enough was orange. I'm slowly trying to get my wheelie skills back without crashing. It's been 20 years since I sold the XL, so I'm easing into the dirt riding.

Attachment 283617

I was told by the Dual Sport Plus guys the most common combo is the 606 front and 908 rear. I have the 908 rear on it at the moment and its great. My next front will be the 606 front. 908 is great for hwy and hard pack, but also did great for me at the EOAR in thick mud. The tire is designed for hard tarmac, rock, hard pack etc, and is supposed to be long lasting wear. yet like I said in the mud it was doing great as well. The 908 Rally Raid Rear tire is great, you wont regret it.

The only regret I have is that it's the better part of $200 American...

Yeah, it might be a little more costly then the others, but its said to get excellent distance, and at higher speeds and on hard pac and tarmac. All in all, I think its worth it. My CBR1000RR tires cost me over 320 after taxes adn instal.

I remember that there was some talk about three of these rally spec and three of the ordinary spec are a good combination!

I'll need the part numbers and there were some in the thread also...

Thanks!

There is no definitive thread. Following should put you on the right path though.

Previous comment that all high flow head bikes had upgraded springs isnt correct, they all had rallye valve springs not clutch springs.

Dunlop 908RR and D606? I like the bigger center lugs on 908RR which should wear better with street riding. I currently have a Perilli MT21 Rallycross in rear and Continental Twinduro TKC80 in front. I'm not a good enough rider yet to know the difference in the dirt. However, on the street, the MT21 is a little squirly on turns. I've already slipped a little down shifting in turns or when accelerating hard coming out of a sharp turn. Maybe this will happen with all dual sport tires hooked up to an LC4. My xl350 never had the torque to let loose on dry pavement. Plenty of thread left on front, so I was debating getting a rear TKC80.

Yes the Dunlop. I was told by Dual Sport Plus that the vast majority go with that combo.
908 rear http://www.dunlopmotorcycle.com/tire...ire.asp?id=96\
606 Front http://www.dunlopmotorcycle.com/tire...tire.asp?id=14
I love the 908, havent had any issues with them, in dry or wet pavement at high or low speeds and was great in gravel and foot+ deep mud.

@GERST
Yeah, these are the paniers I have as well, I really like them, and the water in the side walls with the tap on the back is a nice binus if camping. I recommend these. easy install and removal,. They lock the the rack and they lock shut too.

Question Oil changing????

Hey Guys!!

I bought my 2005 KTM640 adv r in the winter, had maybe 2000kms on it since then. I went to change the oil. I dropped both drain plugs, and did both filters. I did it while on the center stand. I added 2 L of Thumper Oil. The glass is full, so thats good, but I thought after doing it, I only got 800 ml out of it. So basically 1 litre. now, the guy that had before me did the previous and I dont know how far he went on it, so I might have been low. My concern is more that there is a resevoir or something that doesnt drain possibly if its on the center stand, and I may have 3L in it not 2. And thoughts on this? I did push down on the tail of the bike to lean the bike back as well as the forward. Just curious. Thanks!!!

Did you pull the drain plug under the filter (frame drain plug) as well?

Ahh crap, no, I didnt. Hmm. Okay, so i guess I will be having to redo this then. here are some options I thought of, what do you guys think.
1. Drain some oil from the oil pan, until the oil comes into the proper level, and accept that some of it is the old oil still inside ( prob is I dont know if it was syth, semi -syth or reg oil before) ( I added Thumper semi syth.)
2. Drain the whole thing and refill with exsisting oil ( same concern as #1)
3. Drain the whole system and buy more oil ( arg the wife wont be happy, just did the sports bike oil and new tires for both bikes)

What do you guys think? Safe to use the oil in it now? 2 litres of new semi syth thumper oil in it, mixed with whatever was in the frame? or is this dangerous for it?
