Hey y’all I got a kfx 400, rebuilt the carb put bigger inlets on it, adjusted the fuel mixture screw 2.5 turns out and cleaned the fuel petcock. It starts up not so great, it takes full throttle with full choke and cranks for about 10-20 seconds before it fires and while “ideling” it surges very bad and I’ve messed with the idle set and it changes nothing, if you ride it casually it runs fine but as soon as you get on it for more than 4 seconds it stumbles and falls flat on its face and you have to wait for the carb to fill back up with fuel, I’ve checked everything and nothing is blocking fuel, I even put a bigger hose to see if that made a difference. Thanks for reading hopping to hear someone has some advice.
Hey guys! I'm new to this whole discussion thing! My boyfriend and I both ride quads; I ride a KFX700 and he rides a KFX400, LTR450, he also has a Quadzilla. He's also in the middle of building a quad. I know my post isn't relating to parts, or anything like that. But I seem to be at a roadblock. Christmas is coming up and I have no idea what to get my boyfriend. I want to get him something quad related. Does anyone have any suggestions? Thank you so much in advance, I appreciate it!
