    2004 crf100f cutting out

    by Psychosis » Wed Aug 02, 2006 7:35 pm

    Bought this bike used. It ran good for a while but now when you are idling or at low rpm and gun the throttle hard it cuts out. If you are idling and gun the throttle hard it will completely stall and will die if you don't let off the throttle quick. I have cleaned the air filter with no change. I have cleaned the carb by taking it apart and removing the jets, and cleaning everything with carb cleaner and air compressor, no gunk anywhere, hoses are not stopped up, gas pours out of the hose going into the carb just fine. Gas should be new and i have ran a couple tanks since this prob started. I have also tried 2 more spark plugs with no improvement. We can still ride the bike fine it just cuts out when you get on the throttle hard at low rpm. Anyone got any advice or suggestions they can give me? Thanks

    Also as far as I know it still has stock jets in it. Would stock be the best for riding at about 2800 - 3000 feet above sea level or is there a better combo. If you guys can help me let me know what jetting would work best with the plug in and out of the airbox. Thanks

    What does your spark plug look like? That could tell you something about your jetting. We ride at about the same altitude you mentioned. On my boys bikes, we opened the top of the airbox and went with a 105 main and 38 pilot jet. We also added an Uni free flow air filter. Made a nice improvement in the throttle response on both bikes.
