    I have been a wheelie problem with my new 990. The Bike Just would not pull a 2nd gear wheelie! i have 16t cs but every time i tried it it felt like the bike was shutting down on me. Well after a lot of searching i found this mod!!

    http://www.superduke.net/forum/viewtopic.php?t=72

    It takes 20 min and what a difference!! That 20% extra power in 2nd and 3dr is huge!
    i am sure this is old news but i was so excited i had to tell somebody!

    I am pretty sure it is a Euro thing only. Noise regulations stuff.
    But I could be wrong, it happens all the time:lol3

    I was thinking about this thread tonight on my ride, and i had a whole bunch of smart as remarks.. like.....

    Hey thats good to hear, ya know those 990s don't have much throttle response...

    Ya know i was having a hard time getting the back tire to break loose in the dirt...

    There was way more better ones but...


    What i really will say is cool..:thumb

    Now if it gave me more pull in 5th and 6th...

    I am sure you know how your bike pulls, so it must have made a diference.

    I'll give it a whirl, sounds like an easy enough mod for me...

    I was wondering why people have so much trouble doing wheelies.
    My bike has the Acro mapping and never affected me.

    The other benefit of Acro mapping is that it uses fuel faster and lightens the front end to pop it up even more easily.

    This mod is very well known amongst ktm owners here in europe (first thing I did when I got mine). However, I suspect that it is useless in the US, because the noise regulations are less strict over there.
    Also, this mod is useless when you run the sport mapping, for that eliminates the restrictions in 2nd and 3d gear.

    Since it worked for you, it might very well be that ktm does not change the mappings for US bikes after all. Don't know...

    Well i can tell you that the bike pulls a lot harder in 2nd and 3rd now:clap
    and it will pull a 2nd gear wheelie easy. There are (2) 3 wire connectors on lower left side one white one black. You want the black connector. I checked the wires with an ome meter and they go to ground when in 2nd and 3rd. The 3rd wire (light green is for the neutral light) All i did was cut the 2 wires and tape them back.

    If you're not comfortable cutting the wires, you can also push the contacts out of the connector, bend them back and secure with some tape or shrin kwrap.

    I did this mod on my 950SM last year prior to changing the exhausts. From what I have read here and on other forums, it is the EPC, electronic power control, and I think a Euro thing only, (don't quote me on that last bit though).

    On a 950 it works only at full throttle in 2nd & 3rd gear by bleeding a little air into the carb so that the vacuum is reduced thereby preventing the slide opening fully. On the 990 I believe it it has the same effect but achieves it more electronically. I remember reading on HOW or somewhere that you need to put a resistor in the loop on the 990 to prevent the FI light staying on also.

    On a recent trip through Spain & Portugal, I was wringing the neck out of my 950 in the mountain twisties mainly in 2nd & 3rd and there was certainly no problem with power... :wink:

    Hmmm. Never thought about doing this little mod to my 950. I see the wiring in my diagrams. Nothing to lose to give it a try. :D
    Funny thing is I just had that plug in my hands 2 days ago when I did my Torque Limiter update.

    Thanks
    It really does help when we can see what bike-year and what country at least.

    Since the 950 has a more physical way to control power in 2nd and 3d, I would find it strange if doing this cutting the wires thing would work for it. What this mod does is just fooling the 990 ECU into thinking you're not in 2nd or 3d gear so it allows full power. If you do try it, please comment on the result!

    The Akro map makes the fuel consumption even worse than standard no... so does this not have the same effect...?

    From what i understand,on the 950`s if you have already removed the EPC stuff and plugged the carb tops then you dont need to do this.See the HOW.

    I did mine while I was doing the Canisterectomy and the SAS removal. Definitely hits harder in second than it did before. But I can't say which mod did what, because I changed 3 things at once. Bike feels more lively when you open it up so who's to say. Can't hurt to try it. Just cut 2 wires. If you don't like it solder them back together.
