On this 2003 Yamaha TTR-125R dirt bike. Like over a year ago, and now I'm selling it. But I can't get it started, today I replaced the hand grips and the bent handbrake lever, changed the oil, checked the carb which wasn't in need of a cleaning and wasn't at all blocked (There's less than 100 Hrs on the bike I'm sure) and the spark plug seems fine. I even emptied the gas that I wasn't sure if was bad or not and put a little over a gallon of fresh fuel in it. I can get it to almost fire up if I spray a little starter fluid on the spark plug socket but it's like it can't get fuel to keep running or something... Idk what to do now. I don't know a lot about bikes, or even automobiles in general. Just trying to fix this thing up to sell tomorrow. Would reeeeally love any advice blades, thanks ya'll.
