    Well.... I'm not sure overplayed is the word I'd use, but I see somewhat of your point. Do I overall love the bike? Yes. Would I buy it again knowing what I know about it now? Yes. Do I think a bike should come out of the factory as snatchy and jerky as my bike is? No, not really, and especially not at this price point. For me it's not a deal-breaker, but I also have full understanding for those who think it is.

    For some of us, this IS a big deal. Wish you could ride my brand new '07 to see what I mean. My bike stalls, jerks, bucks, kicks....and then sometimes it runs like a dream.

    Three times I've had it stall while in an intersection...not while taking off, but 20 ft. off the line with the clutch out.

    I think this comes down to a throttle position issue, throttle body balancing, and possibly a mapping / O2 feedback issue in the low-mid RPM range (3000-4000). It runs fine BTW, when I riding it hard or during fast cruising, but it HATES my 25 mile commute of stop and go traffic and 50-60 mph cruising in between lights.

    I'm not new to fuel injection or motorcycles and can tell you without a doubt that this is not what KTM intended the bike to be (at least not my lemon).:baldy I'll eventually have to take this thing to the nearest LC8 certified dealer, which is about 150 miles away. Nice.

    '07 990, Akra pipes and latest Akra map, standard otherwise (17/42)

    Instant response ( it's either ON or OFF and in our traffic, i want the ability to pin it in a microsecond) and no flat spots in the rpm range. Quite frankly, the FI on the 990 is better than the one on my previous bike (2005 Yamaha XT660R). THAT one had issues (i even had the updated ECU).

    I tried ONCE to leave without letting it (the KTM) warm up to 2 bars on the temperature dial (don't touch the throttle during warm-up) and the idle was all over the place from 1400 to 3000 RPM. Nearly soiled myself when, during constant throttle, the rpm jumped on it's own (i was in an underground parking lot and i was heading straight for a car). NOT doing that one again.

    2 bars and THEN ride.

    Offroad.. yeah, it's a bit of a handfull but.. i gotta be honest, it's not the bike. I'm just too slow for it. It's not the best bike for a fairly inexperienced offroad rider but every once in a while, you just go a bit nuts (aka grow a pair) and the bike comes to life.

    Can you tell that i love it ? :D

    you should try it with the low oct. wire unplugged. My runns just the way all you guys want it to, normal. but for the road it is wire plugged in all the way! it is like a CRF450 on the streets.. I love it. just my 2 cents?:evil

    I've tried wait for 2 bars, wait for 4 bars, not to wait at all and couldn't see a difference.

    I was doing the 15min idle trick in winter, when it was -5deg celsius.

    For any elevation. The EFI system automatically compensates for changes in altitude.

    There seems to be quite a bit of variability between individual bikes that are not experienced by UJM owners. This is a confounding issue, because two owners of say, 07 990 ADVs can have quite different experiences.

    I have heard some of this attributed to possible batch differences in O<sub>2 </sub>sensors, but I reckon that would be sorted by 08 /09. Perhaps these bikes are made in such low volume runs (compared to Jap bikes) the component batches aren't big enough? :dunno

    Either way, it still comes down to QC.
