[QUOTE="dkb, post: 618139, member: 17902"] Hello everyone, I need a little help. I have a stock 02 yz 125 with a 410 main, 30 pilot, needle in the third, grove air screw 2.5 out. Clean air filter, emptied and cleaned gas tank. Fresh gas. 40:1 (yamalube) and new plug. The thing fires up first or second kick. Idles smooth. It runs great up to 3/4 to 7/8 throttle. But at full throttle it dies. DEAD. It won't re-start when I slow down or down shift. If I hold the clutch in till the engine stops turning and then pop the clutch it fires back up. or come to a stop it will kick start the first time. I didn't change or mess with the float level. I checked all vent hoses and fuel petcock. And cleaned the carb. at least 7 times. Same thing death at full throttle. I also checked the few electrical connections I dared fool with. Is this a cdi problem or ignition problem? I'm about to take it to the dealer :eek: Thanks for any advice Darin [/QUOTE]
