help with carb, new exhaust system

[gtpimp]

i baught a full fmf system, powerbomb head pipe, fmf midpipe, and titanium 4 exhaust, i think it sounds pretty sweet by the way! ok well every once and a while when i slam on the gass it boggs, im guessing i have to mess with my carb and how much air its takeing into the engine, where is the screw for this? btw i was told when i got the 4 wheeler it was jetted for a pipe and never jetted back to stock so i just want to start off by messing with the carb before i decide its time to rejet. thanks, oh yeah i have a 02 warrior

I don't think that any screws are gonna help you. Jetting is the key. You should take the carb apart and see what is in it. Then go from there. It is really not a big deal and can be done in under a half an hour.

The stock carb tends to do that if you really slam on it hard. My friend's is jetted perfectly and it still does it. The only way to really completely stop the bog when you slam on it is to buy a carb with a tuneable accelerator pump, such as the edelbrock or another similar carb. The reason it bogs is because four strokes need a surge of fuel to get the motor reving quick, and that is strongly dependant on the mods your running and also your weight. I had to do a half turn on my edelbrock towards richer to get rid of that bog again after the rebuild, that's quite a bit more fuel just for a cam and piston!!! Your quad can be running great but changing the jets to try to get rid of the bog may not do very much for you, it is more than likely the accelerator pump.
