i just recently bought a 93 yz 125 and it ran perfect. then the other day i was riding some trails and i lost power in first two gears. if i really stay on it i can reach the power band in second but really i dont have any power until i hit the power band at the end of third then it takes off like a bat out of hell. ive already changed the spark plug. cleaned the carb. checked the packing. did a compression test. im at a loss. ive heard it could be the power valvle and govenor setup but i need some advice as to what to look for on these parts. the fuel mixture is 40:1 this is what the guy i bought it from said he has ran it at since he bought the bike new.
