I have an ‘85 and ‘86 250sx in great condition. They ran okay when I got then but I figured a carb rebuild wouldn’t hurt. Ordered the Shindy rebuild kit and followed the excellent carb rebuild tutorial on this site very closely. After the rebuild the bike ran seemingly great. Fixed some other issues like the neutral/reverse light not working, and a new 250es ignition switch since I lost the key to mine. She ran awesome for about 10 minutes until I really got on her and drifted around the yard a bit. Suddenly, the headlight started cutting in and out, and she would just suddenly die. Would fire back up but then limp and die.
Let her sit for about a month. Here I am tonight finalizing some things and I tried taking her out. She would barely start, then only sit idling with full choke until suddenly RPMs would shoot up insanely high to which I’d turn the choke off—she would die instantly. Took her out of the garage and tried riding but she kept dying and the headlight would cut out intermittently.
What the heck is the issue here? I’ve spent so many hours on this thing and its worse than when I started!
Why would it run great, then suddenly once I get on her a “switch” flips and she doesn’t stay running?
