I've found that ~33% rider sag has worked well for me on all of my bikes regardless of total travel. I had Javier work my R shock to get 285mm travel so 95-100mm is where I started. I weigh ~230lbs with a 90nm spring set to 100mm rider sag, I ended up with 20mm free sag. I think that I'd prefer to bump up to the 95nm and it should be spot on for my weight. Forks still have stock .52kg/mm springs and are borderline too soft, but too close to justify a change... I think I just need a little stiffer valving and they should be good.

Had a spare injector so threw it on and made no difference. Checked a lot of electrical stuff and found no obvious fault. Eventually bike started running again so made it about 40 easy miles before it started trying to die again but would catch and keep running until it eventually died again on city streets. Pulled stuff off again, got it going, rode 2 ft and died again. Pulled stuff off AGAIN and started wiggling wires while I tried to start it. Seems to be related to something in or around the big wiring bundle slightly to the front and right and below the spark plug. I started wiggling that and the bike would try and start then die as I moved it. It finally started for good and after that when I moved the bundle it had no effect. Bike ran fine the 10 miles left to home. Time to strip the bike and see if I can find the exact problem.
Exact same thing I've been experiencing, I hope the fuel pump fixes my problem but won't know until I get the pump.

My bike did this for one day about a month or two after I bought it in August 2009 then has run fine ever since until yesterday. I am going to focus on the coil and other wiring first, but I also ordered one of those fuel pumps for the Husky. I am going to clean up the connections around the throttle body too and use dielectric grease.

All things being equal, as the forks have the same 275mm travel as the shock, I'm going to measure front sag tomorrow. I'll then set the rear to the same sag. At least the 2 sides will be balanced. From there I'll make an assesment of what spring rate will be required.

FWIW, I'm at 30% of total travel for rear sag now. I was at 33%, but the action was harsh, I thought I was too low in the stroke.

Trickiest suspension I've ever messed with, balance is not nice.

Visor Down says this new adventure model is based on the RC8 but I see a 690 engine there.



Looks like KTM took styling cues from the old F650GS.

Also looks like someone could use a Photoshop refresher course. That picture is a mess.

Did BMW buy KTM when we weren't looking?

Well that thing sure looks ugly. Lets hope its just another ugly concept photo and if they make a real one they work all the ugliness out of it.

If it does look like that then I saved a bunch of money.

Had a closer look at the wiring tonight. No obvious shorts but one lead on the coil was a little loose. Started the bike and wiggled it around to no effect. The engine only died when I almost pulled the lead off, but there certainly could have been a loose connection there that was causing a problem that I fixed by wiggling the wires around yesterday. I crimped the connector and now it fits tight. I checked all the connector plugs around the throttle body and all looked clean. Added dielectric grease anyway. Nothing left to do now but some test riding.....

The coil connectors have been a common problem in South Africa as well. I've reported on it in the old, recently demised super threat

thanks
btw 1800 miles off road zero problems with anything but the bent rotor. fi worked flawlessly. thanks to those that helped me sort the maps.
bobzilla,

Correct me if I'm wrong--but I seem to recall you use the Scott's shark fin rear rotor protectors ( which are pretty beefy) on all of your off road bikes. If that is the case ( and I know you are a man of few words) would you mind briefly sharing the story of how you bent the rear rotor?

Well its not a 690, but this link http://www.youtube.com/watch?v=zeswy...layer_embedded gives video proof that KTM does quality assurance checks at the end of the assembly line--at least on their 2011 RC8R 1190s. It's a 5 min video, kinda interesting. About 3/4 the way through the camera guy zooms in on a sign posted as a warning to the operator of the testing equipment. I'm curious as to why if the factory is in Austria (I'm assuming)--why the sign is in English and not German?

im not too sure how it hapened either as i do use scotts protector. i do ride it in lots of rocks and have destroyed the chain guide also.
is there a good chain guide replacement?
