    Nice as usual. Will be going to Sweden(markaryd) in the Cage with family week 29. Love that place. Planning a Scandinavian tour NeXT summer if project is ready.

    regards from Denmark

    Markaryd, add 1200 km of boring highway and you will reach Skellefteå =)

    Taking smaller roads into the country and mixing in some gravel your supertanker solution might be needed but you sold the rear tanks? And don't trust the gps to find you a gas station it might be shut down since Sweden is forcing gas stations to have an eco friendly option usually Ethanol and many smaller places can't take the cost of that investment and rather close down =(

    As long as Im not out traveling all visitors are welcome but Im not very good at selling the region, its pretty boring mainly just forrest but there is an endless supply of gravel roads:

    Took the new bike for some local trail this evening.

    First tip over, deep tracks left after forrest machines filled with stumps of logs gave me a hard time, luckily there was a tree to "lean" the bike towards but had to get off the seat to get it back on track.

    Also got stuck trying to get over a ditch filled up with logs to make it passable more throttle might have gotten me over it but I was to much of a chicken.

    Might have to look at some other throttle tube it is a bit snatchy trying to ride the rough stuff, the 950 was smoother.

    Got along with the front brake better this time around at least.

    Need to get the body up to speed also the cardio is at zero it feels like get tired very quickly.

    Have done some more riding with the 990R now:

    [​IMG]

    And done a first oil change:

    Now the question is if I need to spoon on a new TKC80 or run the "slightly used" Terraflex at this weekends gravel get together?

    And it seems like the carbon heat shield is not up to the task, burnt and kind of melting:

    Stay with the Terraflex.

    Rather ride one tire bald than have two half used ones.

    In the end, it feels far more satisfying to have really used up one to within an inch of its life than to have 2 that can't really tell a tale.

    Thank you for that advise!

    Have a few half used as it is, before longer trips I have preferred to have a fresh rubber when leaving from home, but now I have decided to not buy any tires before I have toasted all the tires I have.

    There is for some reason I don't know 2 x brand new TKC 80 and a couple of half used rubbers.

    Hi Johan,

    I also have problems with the Carbon Heat shield. Any idea to fix this or just trash it and back to the metal one??

    Does not seem to get that much worse so will keep mine for now, but the bolts keep backing out so have to keep tightening them.

    Did attend an event last weekend in Boden with Carl Hagenblad who plans to race the Dakar rally who shared some tips and trix ...pretty much "eyes up and more throttle was the solution to everything when riding off-road".

    Almost all the guys were on smaller single cylinder bikes but think all that were not local to Boden area trailered their bikes there, me and my friend Dennis drove there and back (just 180km away so not that far).

    So have nicknamed my bike "The Blue Whale" after that weekend:

    [​IMG][

    Carl showing how to get mount a tire with a mousse (correct english term? in Swedish we call them "korv" direct translate would be sausage):

    [​IMG]

    Did run into trouble with the side stand switch going across sand whoppies so took magnet off, plenty of metal on it??

    [​IMG]

    Just for information you have to keep it the same way if taping it in place as I did but first try I had flipped it around and that did not work.

    My friend Dennis:

    [​IMG]

    Was going to give the bike some love since some "oil" made the engine a little messy:

    [​IMG]

    Seem I was not able to squeeze enough oil out of the rottweiler filter:

    [​IMG]

    Would think the small excess is pushed back and when on side stand drips of on the left side, might have to make a habit out of lifting out the dog house each time I have seat off and wipe off that rear left section on the mounting plate to reduce this.

    Also gotten around to installing the Carbon Fibre side panels:

    [​IMG]

    At first the right side looked scary close the the muffler:

    [​IMG]

    With it all bolted up it looked better:

    [​IMG]

    Still a little more gap on the left side but good enough should not melt stuff:

    A little video comparing carbon and plastic:

    Did not work embedding video uploaded on flickr so here is link:

    Choose to go with Nomad rider luggage, a small for day rides and also bought a medium for longer trips, liked the external easy access pockets, time will tell if they hold up:

    How much hotter does the 990 run compared to the 950?

    Seems most of the subframe is to hot to touch, at least a lot more of it compare to the 950 and parts of the swing arm is also plenty hot after a good ride.

    See around 6-7 bars and on idling at red lights and such it goes up a little more 8, maybe 9 but by then the fan is on and there are several bars left.

    Have started toasting my pants maybe the bolt gets hotter with the carbon heat shield compare to having the stock that would probably spread the heat better?

    [​IMG]

    A little worried about how much hotter it feels, have an IR thermometer on order from China, will do some measurements once that get here.

    Have had it push quite a bit of "goo" out of the air filter that made a bit of a mess around the rear cylinder, skipping the hose directing crank case ventilation into the intake itself might have caused some of that and a little excess filter oil another factor, will try to get a hose in place in the near future:

    [​IMG]

    The "Blue Whale" as I have named the 990R sure does deliver compared to the 950 but have not had the time to ride as much as I would have liked =(

    That's an issue with the clear coat over the CF. Heat transfer from the fixing screw. No need to worry.
    If your really concerned you could wet sand the clear off back to the CF and recoat but if will just happen again.

    What I at first thought was the carbon fiber "melting" the black on the bolt was actually a tiny damage to the pants leg ...since it has burnt the pant leg a lot more.

    Carbon fiber seems to have a hard time handeling the heat still, a little burnt around bolt and feels alot softer when hot compared to cold.

    Something needs to be done if its supposed to run this hot.

    Never burnt anything on the exhaust on the 950 so why is the 990 burning stuff?

    As I said earlier everything around the exhaust seems to get quite a bit hotter then the 950 ...normal??

    Might try to source some ceramic and make something separating the carbon fibre from direct contact with metal that might work better.

    Johan this is the same problem that I have with my 990 A 2011. it runs really hot specially here in Brazil.

    What burns our pants is not the shield but that screw the middle one.

    I am very disappointed also with the carbon fiber shield because it is disintegrating due to heat and still burns my pants..

    I eventually return to the metal one.

    Even if we have had the hottest summer ever with like 2 weeks of day temperatures reaching close to 30 C (probably cold compared to Brazil) the 990 for sure seems to run hotter compared to 950 with similar riding.

    Will talk to a friend that works with heat probes at a copper refinery measuring the temperature of the molten metal and might have some good heat resistant ceramics that might be possible to use to isolate the carbon fiber from direct metal contact and cover up that bolt in some way.

    I have some kevlar i can ship if wanted.

    How did the suspension handle the sandy racing codition.

    Kevlar textile? Or what do they call it in english? Quilt?

    Have discussed the problem with a friend and he said stainless is a poor heat conductor compared to steel.

    Are bolts stainless? That would help keep the bolt temperature down especially if having a "heat sink" in the form of stock shield.

    There are ceramic washers but they are hard and brittle and won't work on a counter sunk bolt. But there is some heat resistant "cloth" that can be cut into washers that might help isolate carbon from direct contact with the bolt.

    Solution about bolt burning up pants might be some kind of cover over the bolt head but need to find some solution how to mount that to the carbon shield.



    Suspension worked plenty good but was not able to bottom it out so must look at making it a little softer, need to swap springs in forks (have them), worried I would benefit from a softer rear spring also and some dialing in the knobs.

    Need to stop being lazy and start riding more.

    It is kevlar textile. I thought you could lay up some heatresistant.

    ahh the 320mm suspension is the second thing to do when my project engine is done.

    Have tried adding that piece of hose I skipped during install of the CPR filter to try and reduce goo around rear cylinder:

    [​IMG]

    But as others said it is impossible (at least very hard) to get filter in place then since its a stiff hose and it is so close to the filter cage and cant go anywhere I skipped the hose clamp and it was possible to get filter in place properly:

    [​IMG]

    Have not had time to ride it enough to evaluate if its any better yet.

    Been using the old 950 to and from work but ran into trouble with that one also.

    Went by gas station today and at a line of red lights while idling it boiled on me spewing coolant all over my boot.

    At last red light I noticed 6 bars on temp gauge ...never seen more then 5 before so felt for fan, NO fan, but just got green light so took off by it went up to 7 with warning light just as I took off but kept riding the 2 km back home and it went down to 6 bars before turning it off.

    Expansion bottle was almost full, pulled contact on radiator and with that shorted out fan starts so seems sensor is dead.

    Is there any good replacements? Any car that use the same sensor? No local KTM dealer so will be a little while before I have enough to justify an order (waiting for one from Germany that for some reason was returned but talked to them today and they will try to send it again and this time I will follow the tracking better).

    If it cools down and not drain the expansion bottle completely will I still need to bleed air out of coolant system?

    Installed the SE brake master today but did not have time to try it out was dark by the time we finished in the garage and took the 950 back home and after plenty of tries the high beam fired up.

    Ended up investing in a 4 pot caliper and a 320 mm disc also that I recieved today, price was right so will see if that will fit later on, quick visual check looks promising.

    EDIT: Might also add that with low fuel light on 3rd gear 110 KM/H a little pull on the handlebars and health dose of throttle and front wheels lift right up =)
