[QUOTE="razor, post: 1236522, member: 81255"] Hello out there!! I just joined and have gained a ton of information. I just bought a 1989 RM250. The bike bogs down in first and second gear. Once I get into third gear it takes off like a scladed ape. Sometimes it seems like it wants to run the way it is supposed to run. It also smokes a lot in those two gears. I have only changed the pilot jet. The stock one is a 55. I put a 50 and it did the same thing. I put a 45 and it did the same thing. Do I keep going down on the pilot jet to a 40? The motor has been rebuilt and the only modification it has is a pro circuit pipe. I also checked the reeds and they seemed ok. Plug keeps fouling. The bike starts easy. 3 kicks at max. Any input would be greatly appreciated. Gracias. [/QUOTE]
