    Good luck with the next bike, whatever it may be. Don't be a stranger. :freaky

    About three years now. The brush really works and the cleaner is kerosene based.

    The lube goes on clear, doesn't fling off and stays reasonably clean..

    Further, their Speed Wax is the best thing I've found for our tanks. Leaves a great low-lustre shine.

    Has anyine installed A Givi Monokey trunk on their 950 SM? My bike currently has this plate on the back;

    http://www.ktmtwins.com/ktm-950-supermoto-super-enduro-topcase-bracket

    I have access to a Givi mounting plate that is much larger than what I need. I plan to cut it down and drill new mounting holes, but I need a little help on where to make the new holes. What I don't know is how far forward or rearward the Givi posts are in relationship to the front mounting holes.

    If your chain is making a lot of noise, it's probably history. I use the highest quality chain I can buy (to me, you can't get a better chain than DKD ZVM). And also good sprockets. And in my opinion, .300 or .375 is too tight. I run the bit looser than most, an old employer of mine, an AMA Tuner of the Year, told me looser is better than tighter, too tight and you wear swingarm, wheel bearings, countershaft bearings and everything else. A lot of people (in my opinion) don't pay attention to their chain maintenance and some people pay the big price when their chain breaks and goes through the cases (I totaled a bike like this, repair cost more than the bike was worth).

    This! :nod

    On my Tiger (which I owned prior to the SMR), I started losing coolant. It wasn't on the ground, and it was persistent. (Occasionally, you might overheat and coolant will belch out of the overflow. If your levels are going down all the time, that's different.)

    This might be accompanied by the bike running "hot" -- maybe one bar over the usual level.

    Eventually, the oil contaminated with coolant will whip up into a mayonnaise, like this:

    :eek1

    If you run on "oilant" for very long, you will wear down your main bearings, and fry your engine. I've not yet gone through the ritual of water pump replacement, but if I started losing coolant through no obvious leak, I'd check the oil filter. If it didn't look "normal" (pleats should be straight -- not "wavy") or if the oil didn't look right, I'd replace the pump. It's relatively cheap to fix, thankfully.

    BTW, if you drain the oil, it might not look very odd. The engine heat can boil off the liquid in the sump, but your top-end might be filled with mayo.

    Looking over the sprocket on the real wheel while the new parts are in the mail. How do you get it off? The hex heads on the bolts are on the inside of the wheel.

    The sprocket carrier just slides out from the wheel, once out you'll have easy access to the bolts.

    Strange... This afternoon, after an 11 mile ride home in about 80F degree weather, I parked and I heard a whining sound. Video:

    I assume that is caused by pressurized fuel from the heat. Is that normal for the SMR?

    Could also be a partially blocked vent line. Id guess it was trying to draw air in because of the drop in fuel level? Though 11 miles wouldn't use much fuel. Check your vent line for blockage and that it isn't kinked.

    Air was blowing out, as far as I could tell. I just assumed it was from gas expanding in the heat.

    I just picked up a 950 SM and am having some issues that I think are related to the fueling. It has FMF 4.1 silencers I havent opened up the carbs yet to see what jets it is using. The issue I'm having is with jerky throttle response going from no throttle to very little throttle at low speed (way more abrupt than my 525 or 200). Also the bike has died while idling when warmed up. Has anyone else had these problems? Any ideas? I don't really want to use one of the jetting setups that use a prefilter if I don't have to. I won't be riding in the dirt very often so they don't seem like the best option for me.

    What year / how old is the bike? Mileage? Could be just gunked up carbs from ethanol. I'd say clean the carbs and set the floats to spec before changing anything. Maybe raise the the needles to position three like most have to eliminate cruise surge. Clean gas in it? Has it sat awhile? Good plugs? Clean air filter? Do the basics first.

    I have searched everywhere and can't find the orange tank spoilers for my KTM 950sm. Can someone please point me in the right direction.

    It's a 2006 with 6000 miles on it so i think it's safe to say that it has done some sitting. My first thought was clogged jets from lack of use, but it will usually start without the choke around 55F and the exhaust smells gassy at idle so it might not have stock jets in it. I'm going to put new gas in it and ride it. I might have time to clean the carbs this weekend. Hopefully I will find stock jets that are just gunked up. Low speed throttle response is terrible right now.

    Sounds like the pilot circuit id fubar'd.

    Don't waste your time with new gas, it won't help. Pull the carbs and clean them well.

    Howdy!

    I posted a couple weeks ago about my '06 SM. She sat for about four years and was recently given a thorough carb clean-out and run check by a reputable mechanic right before I took took delivery from the PO, who is a dear friend.

    From what I know about the bone-stock Cal emissions nonsense on these bikes, they're expected to do at least a little bit of backfiring on decel and be a bit stumbly off idle, with occasional stalling at idle.

    This bike is no exception; it has exhibited these basic traits since day one.

    I have no reason to believe that any of the typical fixes have been done to this machine (i.e. jet needles at third position, SAS yank, Canisterectomy, etc.) and I am actually not sure if the carbs were synced when the bike was examined last (we asked for low budget get 'er running, not full going-over from the mechanic).

    Things were going okay in a daily-rider sense (I had gotten used to the not-quite-all-there feeling of knowing I have some work to do) until yesterday. I took her out for a short blast through the city and she started acting really grumpy. Really grumpy. Difficulty accelerating away from lights at like 1/8-1/4 throttle, surging after 1/4 throttle (terrifying!) and general rough running at anywhere under 25mph.

    I'm in the final stretch at school and my time is at a premium. I have the SAS block-off plates and was considering burning off a whole day doing that, but noticed on one of the many tutorials out there that there was a warning against pulling the SAS if you have stock pipes with a cat.

    Other questions I have are,

    1. Has anyone had luck using Seafoam in these bikes? Are there any quick-fix plastic-tank-friendly fuel system cleaners that are approved for this machine? The carbs were gunked pretty bad when the mechanic was in there, I figure it couldn't hurt to run some cleaner through them...

    2. Would it be a good idea to just get in there to pull the needles out a notch? I'm pretty comfortable getting in there to do just that one thing. I don't have a lot of $$, so going to a mechanic or throwing down for a jet kit is kinda out of the question, at least until summertime.


    Thanks guys!
