this is a post from a local forum. everyone on that forum is a dumb $hit or if they know, they don't help. might as well ask you guy's
last time he posted, he said it starts up w/ the choke on, then dies when choke is off. i told him to raise the idle by twisting the black nob in the left side farring. i guess he tore apart the carbs and @#cked it all up. poor guy...
"Last time i posted i said i had a head gasket problem but now im not so sure. Well lets start off from the beginning. i have a 1995 ninja 250. I just bought it a couple months ago. The last owner said it sat for 2-3 years.
Now to the problems i have. Today i tried to fix some of the problems. Last time i cleaned out the carbs and changed oil and oil filter. But my bike still didnt idle right. It would just die when i took off the choke. Now today i decided to change both spark plugs. Then i decided to try and start it up. It still had the same problem as before. But now ii noticed that my left side carb is overflowing. Lots of gas is coming out of the intake. Could this be the float is stuck open?
Also i tried messing with the black knob on the carb(idle??) but it still didnt run good. But i got it to run without the choke when i adjusted the knob. But then it would rev to 4k then back down to 1k and it would start knocking.
So then we decided to drain some of the gas out of the tank. (there is a lot of rust in the tank, anyone know how to clean it out??) so a lot of rust came out. Could this be causing my engine problems?? Bad gas and rust, since its been sitting for 2-3 yrs??
So then i just decided to put the tank back on and try to ride it. (My battery is dead so i have been using a battery jumper) So i started it up with the battery jumper on. Then as soon as i took the jumper off the rpm guages went crazy(showing 8k) also the lights dimmed. So i came to a conclusion something is wrong with the generator because even with a dead battery the generator should keep the bike a live. Anyone got a better solution???
So then i figured out that if i kep twisting/untwist the throttle i could keep it a live (kind of) so i jumped on the bike put it into gear let the clutch go and off we went. But something was wrong, i was at full throttle and only goin like 5 mph. I could walk faster than that. the bike wasnt even going anywhere. twisting the throttle did nothing.
Also could this be a sign of tight valve??? the previous owner never adjusted the valve. the bike has 13000k miles.
Please someone help me. im getting mad."
