I have a 2001 Yamaha Blaster 250. Bought it brand new and have never had any issues out of it. About a year ago I rebuilt the carb after it sat in storage for a while. Well we had it out riding and it was running normal no issues. We shut it off after getting back to the truck and got a drink and rested. Well when we were ready to start riding again it started rode 75-100 yds and then died. After several attempts at trying to kick start it I had the guys give me a push and tried to pop the clutch. Still didn't start. Well I've tried all the ideas i could think of to get it running again. I've replaced the spark plug, the gas, even the oil. If I remove the seat and the top of the breather it'll start but runs really rough. Thought it was a carb issue and needed adjusting. Every time I replace the breather top and seat it wont start. Also when I try to give it gas it bogs down and dies. I cant figure it out. Any ideas?? I sure could use the help I'm fresh out of ideas. Is the CDI box? Coil? I'm not sure.
