    Having the time to warm to two bars is simply a matter of proper planning. I start the 990 as soon as I get to it, and by the time I have my jacket zipped and buttoned, my helmet on and my gloves on, the 990 is going to two bars about the time I swing my leg over. No wasted time.

    As for comparing with your car, you should do this with your car as well. Let the oil pressure come up, and allowing a little time to gain degrees F will extend the life of any engine. But, this is even more critical on motorcycle engines. When was the last time you saw a car engine that produced over 100 HP on less than a liter motor that weighed only 126 pounds. Exotic materials and tight engineering specs require "better users."

    The 15 minute run is allows the ECU to store its settings in Flash memory, and shouldn't need to be done unless big changes are made to the system. The two bar warm-up should be done for every cold start and, as indicated above, can be done without losing any precious time. IMHO

    I am not doubting you for a second (after all, you offered to buy me a beer so you must be a man of intelligence and character! :freaky) but I am confused by the conflicting opinions I am seeing.

    My BM (EFI) was recommended in the owner's manual to be started and ridden, no warm up time.

    When I picked up my 990 (I love saying that: my 990! :D) I specifically asked the KTM mechanoid if I should run the engine when I start to warm it up before riding and he said no, start and ride, just ride easy until three or four bars.

    I have assumed that this is due to the EFI as every carbed bike I have owned has needed the start up, suit up, then ride option, as you are using.

    So my questions are:

    1. Why are the mechanics saying start and ride, what harm do they think will be done by starting and standing?

    and

    2. Why are you saying start up and suit up, what good do you think it will do the engine to warm up prior to take off?

    :ear

    I always let the engine to warm up before touching the throttle and as reported I havent experienced the snatchiness problem.

    Dsherod, :clap you hit it.

    I nominate this to the HOW!!

    And you left your new bike to that mechanoids??? :rofl

    Cause he doesn't know. Its always good to let the internals lubricate a little. I cant recall exactly, but i think I read to let the engine warm before riding, isn't it on the manual?

    I do the same. Start up the bike, then finish gearing the jacketed, helmet, gloves. DONT touch the throttle when firing it up.
    What DSHerod is saying its the most (makes sense) thing I've heard in long time, I wish he can solve now the windscreen disgust!!

    BTW are you testing the SM/SD?

    Same here.
    I warm up to "operation temp" my 990, my car,...if one day I have a ship I'll warm her up too!
    In the 990 I wait for at least three bars.

    To me it's not a matter of FI/carbs but of proper lubrication and tolerances (is that the right word?); engines are built to run with a given tolerance between the parts when hot enough. Before they are properly warmed up, the piston reaches high temperatures before the cylinder does, so they get different dilatation. Guess the same thing happens in other parts of the engine, and I guess that's not good or at least, being not a mechanic, I don't feel comfortable letting the engine running that way.

    Damn ... I just read my explanation above and it sucks. My english sucks too. But my bike rocks !

    Oh, I can do that, too. Stop growing at 5'7" and when on the street wear a street helmet, i.e. no bill. :rilla

    Nik,

    Actually, I offered to buy you lunch, but then you wouldn't be the first Brit I've known whose lunch is liquid. :rofl

    Actually your English is better than many natives. Also, your explanation is well said.

    You better stick to engines and avoid aerodynamics :lol3

    I past the height long time ago and always wear a street helmet - in fact i was considering getting an off-road helmet.... but that belongs to another thread. cheers!

    He's a great mechanic, really, spot on, very anal, I like that in someone who works on my bike! :D

    I've always warmed my bikes but the BMW manual actually said not to do this, this is why I asked about this one.

    I have now started doing this, can't say I have noticed a great difference, but then it is fresh from a service so it is running at its best form, I'll see how it is in a couple of thousand km before I make my judgement!

    Yeah, I took the 690SMR Prestige for the day, will post about it on the dilemma thread! :D

    I hate to be a pedant in the face of unbridled generosity but your offer was to break bread, one which I appreciate and look forward to, however, look at the ingredients lists for beer and for bread: beer is bread in a glass! :lol3

    It's tempting to embrace Goti's comments on internal tolerances, but an engine warms up more quickly and more evenly under light load. As soon as oil pressure is maximized at idle and circulated throughout the engine it should be lightly loaded to warm up properly. That means ride it, but sensibly, until full operating temp is reached.

    The operating instructions for my Cummins turbo diesel say:

    - Start the engine.
    - Allow oil pressure to maximize (see gauge).
    - Raise engine speed to 1000 RPM for 30 seconds.
    - Drive.

    Excessive idling is not good for any engine. Unless, of course, it's been broken in by the motoman method and is filled with Amsoil. :D

    Excessive idling is 12 hours of trolling on a warm summer day in my SeaCraft, warming to two bars is not excessive.

    I've now been doing the two minute warm up idle and I have to say, in all honesty, there is a marked improvement in the snatchiness.

    It was never a problem to me anyway, but the bike was not as smooth as it could be at less than 4,000rpm.

    Now it is totaly smooth, perfect.

    Thanks DSHerod for the tip, I guess I'll be buying the beer then! I owe you one!

    :D

    Hello all,
    I am very close to buying a 07 990. I test rode the bike the other day (dealer consignmenet) and loved the ergos, the engine response and the handling. The fuel injection was a bit disconcerting. I have ridden EFI bikes, but many years ago and the sharp on/off throttle has me thinking twice. I did let it warm up for a short period but not two bars.
    Are the 07's more twitchy than the 08's, is it just a characteristic of the EFI?
    I did get better with the throttle as the ride went on but if it is an issue I am thinking maybe I should look at another bike.
    Anyone else with these concerns or history?

    Jeff

    The 07 and the 08 are the same bikes. KTM's, the manufacturer, model year calendar runs from July to June. KTM NA's, the distributor, model year calendar runs January to December.

    That being said, there have been some EFI map mods from the manufacturer, and there are several documented remedies or workarounds. If you are ready to buy, I would ask the dealer to make the bike perform like you want before you buy. If it's still an issue to you, there are a few new 950's at dealers and then there's the 950 SE.

    It is your call, but as you said you will get better with it, and the bike gets better with more miles, as well. I've never had a problem personally, but YMMV. It may have something to do with my riding style since I can't imagine why anyone would want to go slow :rilla

    Okay, a little update since I have followed DSHerods start up and suit up approach:

    It is a miracle cure!

    I didn't find the snatchiness a real issue before but since doing as DSHreod suggested it is now competely gone.

    To arrive at The Girl and my place I need to pull away from a set of lights (always red :ddog) turning left, travel 70 metres, turn right, travel 30 metres, turn left into a car park, go through the car park, do an almost U-turn around a tree and pull up next to the steel barrier I chain to.

    All in first gear, used to require a little clutch use, now I just use the throttle and it is smooth as a baby's bum! (Not that I spend my time checking! :D)

    Really the snatchiness is a non-issue if you warm before you ride.

    :D

    ****UPDATE****

    I posted on a similar thread the other day about the FI issues

    I complained that my girlfreinds helmet kept bashing mine caused by the jerkyness

    Well I tried the two bar warm up and it has made a massive difference.

    Also i had done about 800 miles then and 1200 now and it gets smoother and smoother every ride. So now i am thinking about how fantastic this bike is and not about the snatching.

    I have ordered the G2 Throttle Cam which i will report back on soon.

    I had the chance to test ride a 1200GS the other day which was a really interesting comparison, heres my thoughts (sorry i know this has been done before but this is from my perspective of only the third road bike i have ridden! ,the first was the bike i did my test on :D)

    The GS:
    • Slower accelerating
    • Buffeting off the screen is just as bad
    • Much worse wind noise for my GF on the back
    • Better at crusing at 30MPH
    • Exactly the same as the KTM on slow speed manouvres on the throttle - I was really supprised by this I expected it to be smooth as butter!
    • About the same engine braking
    • ugly cockpit
    • just didnt feel like you could take it off road
    • Honeslty it was just boring to ride
    I could not wait to get back on my KTM so much so that we went out as soon as we got back and it was peeing down with rain :D

    Nik, I too have a left turn at a red light just outside my place... Or, I can go the long way around which includes a small offroad section that circumnavigates a baseball field. Heavy erosion, requiring gentle throttle use and stand-up to cross this section. Damn light :D

    It's a brief stint that I look forward to every morning, akin to my morning espresso, which I also like short.
