Hows it going guys? I have a 1980 sr250 that has been giving me nothing but a headache. Im hoping someone can help me. Im 23 years old and this motorcycle belonged to my grandfather who now passed away. The bike was passed down to my father. The bikes has not ran since 2001. A couple months ago, i decided i would go outside and work on this bike and see if i could get it going. A thorough carb cleaning, a semi decent cleaning of the gastank, and a new battery, and the bike fired up. My father was thrilled. I turned the choke off and grabbed some throttle and the bike died. My father then reminded me that ge had spent a countless number of days trying to fix the bike and he had givin up. He just couldnt figure it out. Me being the ignorant son that i am, felt like i was going to prove to him that i could get it going. Now for anybody thats going to say my pilot jet is the culprit, i have cleaned this carburetor about 8 times. I took out each jet, o ring, and used carb cleaner and blew the circuts out with compressed air. I am absolutely positive that my pilot jet and main jet are mecanically tip top. What could be causing this condition? This bike is consuming me and i will not stop untill i figure this out! Thank you for your help!
