I have a 2000 Scramber 400 2X4. It will not idle and when I get on the throttle it will not accellerate for a couple seconds. It seems like it has to 'spool' up before it will go.
I have taken the carb off and sprayed it out and cleaned it best I could. It seemed to run a little better after I did that, but within minutes it was back to the same 'flat' spot when excellerating.
When it does go, it seems to run very good when it takes off. It will catch you off gaurd if you are not expecting it. There is just that boggy spot off idle and the lack of idle.
I have not had it apart. I wouldn't even know where to begin with that. How difficult would that be to do? Just curious, why would the clutch make it act this way?
Take the carb off and clean the pilot jet out(all the side holes and the main center hole)Clean the main jet too

I was thinking that because of the idling problem that all of my problems were carb related. But I have been looking, based in Islubecki's response, at the clutch buttons as a possible cause of the 'bogging'. It definately makes a lot of rattling noise at idle.
Is the bogging until I get moving the clutch buttons and if so, is it the primary or secondary? How much are the buttons and how hard are they to replace on my own?
Secondary buttons wont cause an idle problem just a bog and lose of power

while you have your carb off pull your reed valves and check your piston skirt to see if its broken.I would all so check your compression if your carb is clean.I have one in the garage right now that acted like yours the owner cleaned the carb twice that didnt help at all.The piston skirt was broken off and it has a crack in the crank case.
check your air/fuel screw as well, and your throttle freeplay if its real loose it cuts ignition, its a safety swith 1/8 inch of freeplay is spec
