ok so i bought this 1991 rm250 about a month ago. needed some work, finished the work, after that it starts first kick! but after i went through the gas the previous owner left in the bike i put in some of my own, the gas was 5 months old with oil mixed in it, 91 octane gas, i put it in and ran it to warm it up to go on my first ride, then after about 2 minutes of idling it started to make a funny sound and the motor shut off, i was like huh? thats weird, started it again and listened idling it and it sounded like dry metal on metal so i shut it off quick! and walked away because of frustration. now a week later its snowing so i wanna go cruise around and do some drifting, so i go out and the kickstart is really hard to push down! it moves down but is very hard. could it be that the oil in the gas settled and became less lubricated? could it be that since its 19 deg outside that the motor is really cold? i have just water in my radiator now so maybe that's frozen and keeping the water pump from turning which is keeping the motor from turning?
