    My 990 with 8500 miles feels like its having a fueling issue. At highway speed, and rolling the throttle to pass a car it happened. It feels like it just ran out of fuel. Roll off the throttle it comes back to life. It has done this several times today in a 100 mile stretch.

    I stopped and it would idle fine, shut the bike off and it would fire back up. Then the bike would act fine. Not-showing any error lights or codes.

    I'm 300 miles from home, and hoping for some ideas..

    Thanks Smitty

    Fuel filters. If it is, limp home the 300 miles. Its a simple job but so many potential issues can come up, you want to be at home when you do it.

    I just had the same exact issue...bike would run perfect up until I gave it some throttle, then it would bog out.

    I was over filling the gas tanks to try to squeeze extra slab miles out of it, and the charcoal canister got some vacuum lock starving it.

    Have you done the canisterectomy? Have you been topping the tanks?

    If so, that's it. Just Let it dry out a bit and stop over filling the tanks and you'll be good to go, :freaky

    I do have a habit of filling to the top. Just hope that's it. I would hate to limp it home and kill a weekend riding..

    Thanks Smitty

    I have a set of filters at home (duh). Just thought at 8 thousand mile it wouldn't need filters yet.

    I bet you're all set if you just give it a chance to evaporate a little. STOP filling it all the way, and make sure you're doing the Right side tank last by the way. If you fill that one first and then stand the bike up, it will most definitely over fill and plug the charcoal canister - for reals too....:D You could also unplug the drain tubes if it's keeps acting up.

    You don't say if you've done the canisterectomy or not - keep in mind this only applies if the canister is still in the evap circuit.

    Keep calm and chive on..... :lol3 :freaky

    It still has the canister, and is stock.

    Thanks for the comments and ideas..

    Along these lines, there is a hose coming out of the canister with a plug in the end. Pull that plug and let any excess fuel drain out. Been so long ago since I removed mine, I can't even remember where it's located.


    Edit- sounds like you got it going. :thumb Keep that plug in mind in the future.

    A great way to find out if you have a hose issue, or a possible kink in a hose can do this to you as well. pop open the fuel cap, there is a small black rubber port with a hole in it on the side of the cap ring. get a straw or a hose of sort and press i firmly to the top of that black port and make sure that you smooth airflow back and forth on both sides of the tank. mine had a kink in the hose and it gave me fits as well. if both passages are clear then i would look into the filter but i bet this if your issue. on my 09 the canister does not have a plug at the bottom of it so it cannot fill with fuel and hold it in, not sure if yours is the same way or not. i just disconnected the canister from the tanks to prevent future issues since the vent hoses have to make so many twists and turns. good luck
