    They do like to rev. I have the 16 tooth on mine and don't use sixth gear till I'm doing at least 70.

    Drop a gear, the bike loves it!:1drink I rarely get out of third around town. I've got to try the 42t and 44t sprockets I bought this winter.

    I'm not labouring the engine. If I was in any gear, mid way through the rev range at part throttle, open throttle fully and you go through some vibes before clearing them and taking off. You feel it right through the chassis when you do this?

    Did 700 miles last weekend - took Friday off - I was playing through the rev range and noticed the same thing. There seems to be a range I get some vibes at while I power through it. I was going to check the torque on my engine mounts.

    After 700 miles through North Georgia, Tennessee, and North Carolina I love this bike more than ever. The only bike I may be interested in is if Aprilia does come with a 1200 V-Twin in the Dorasoduro.

    It's not a super smooth engine; however mine is much smoother at low revs since I've had it jetted and the carbs balanced. I used to have to keep the revs up or it would shudder pretty badly. Since the carb work it's transformed. It pulls quite smoothly from near idle up to the rev limiter cut in. In fact on twisty roads that I used to use two gears on I can now use the higher cog exclusively. I find that I'm able to carry a bit more corner speed in the higher gear but still get decent drive out of the corner. Also I can use 6th from a much lower speed say 68-70mph as compared to 78-80mph prior. Note: I am running the 16t front sprocket. While you may not get a vibe free engine from carb work alone you may find the low engine speed shudder to be eliminated with some careful tuning. Good luck to ya!

    After riding twins for years, mostly of the boxer variety, the 950 motor is dead smooth for a big V twin. I would suggest all motors have resonant frequencies that will become more or less excited based on RPM. I am new to the 950, but my sense is when the engine is lugged or at fairly low RPM and throttle is increased it tends to shudder a bit. This can be smoothed out by dropping a gear. But absolutely there will be portions of the RPM range that have more peak vibrations. All engines are like this, just some more noticeable than others. For me, I totally dig the feel and vibration of this motor. I am always very aware that there is a very strong and slightly pissed off engine below me. If it were smoother it would be a souless japanese inline. Had those!! No Character. On the other hand crazy shaking like a Harley or Buell. No Way. That is poor Engineering.

    So I'll take the Vibes. Not intrusive and I know I am riding a strong bike.

    Anybody ever fit a new guage package off a SuperDuke or a 990SM to their 950? Wonder if the wiring will plug right up?

    Not sure I have to have a tach but the newer gauges look nice.

    Did you feel like you lost much top end when you changed the gearing? I'm thinking about installing the 16T because you really have to be doing over 80 before 6th gear unless you want to be lugging the engine. Hypothetically speaking if one drives at speeds near or over 100 MPH would one be disappointed after the change?:wink:

    thanks

    No, not at all. The bike is ridiculously over-geared from the factory.

    Come chain and sprocket time, I'm going up three on the rear also. Should be a hoot then!



    Somewhere, buried in the bowels of this novel of a thread, somebody did fit an SD dash, or tried to anyway. Search is your friend...hopefully!

    JBird -
    If you find the link to the dash install, please post it.

    After nearly 45 years of riding with a tach I find that I miss it.

    I bought a 950 today in tampa,fla.It has 866 miles and was in his garage for the last 18months with very little cranking.He had to replace the battery to try to sell it.IT IS BEAUTIFUL!!!I drove 625 miles from gulfport ms to give him 8000 for it.He also gave me the 48 month extended warranty,but I haven't read it completely to see if it really is transferrable'sp'
    Anyway,he told me it did not run like this when he parked it.He thinks the starter motor and rear master recall were done before it left the dealer in ca.How can i find out?
    No really,I am about to come to the point.The 950 starts perfectly-then purrs at idle.The next 1000 or so rpms is like ridding a bike that has contact points that kick in after rpm builds,then perfect again.I figured the float bowl/needle jet would let it idle,then die when throttle is turned.
    I stopped at a nice shop in pensacola,fl on the way home and bought an oil filter and spark plugs,forgot the 5.1 brake fluid as I talked.I will change this stuff tommorrow but I feel like i will not cure the real problem without some seriuos insight from some of you.
    I've researched this bike for 1year.iT IS STAYING.
    where can i get a good repair manual and where can i order parts online with good service?
    HELP------------------------,PLEASE,

    I recently bought a RevLight on British eBay and have it mounted on my bike.

    I still have to hook up the wiring, but saw this of one in action.

    I will post after I get it running.

    There is a whole thread about it in the LC8 forum of KTMtalk. I'll see if I can find it later today.

    Edit: Found it: Linky

    contact head2wind on this board. He will set you up with a way better jetting solution.

    It sounds like some small orifice or orifices (jets) in the carburetors have varnish deposits from sitting for 18 months. I'd try disassembling them and using carburetor cleaner on all the jets.

    18 months? Oh yeah...carb rebuild time. This is the problem with bikes that sit.

    I order all my parts from Munns in Texas, but there are other good choices.

    I just thought of something.He bought the bike in ca 4/28/2007.he used it for commuting back and forth to work.When he moved to tampa he worked at home.it was used very little there,That means it is jetted for ca. and also has all of that smog junk still on it.
    What do i take off?I will clean carb as I rejett.
    THANKS,CLAY

    So on my new to me SMR, it has LV peipes and has been rejetted, though I do not know the detail. It has @ 1300 miles on it now.

    I am fairly certain it has not been decannistered, etc. I was planning on doing that. BUT, This thing runs SO WELL. Carburates so well. Starts perfectly, idles perfectly, no flat spots. I am concerned about messing with it. I have heard these can be a bit finnicky on jetting etc. So am I missing something. Sure, it will get rid of a bunch of hosing and a few pounds, but I thought the primary reason for the work was to improve running, stalling, etc. I no gots these problems. What to do?
