so i got a 05' vstar 250 from craigslist theres the problem and it was running great until it started raining down here (the gas cap on the bike is loose so water got into the tank) and it started bogging down from rust getting mixed in the gas, so i took the tank off and cleaned the rust out using vinegar, worked great, clean tank, i took apart the carburetor and cleaned it (let it soak in gasoline, used a toothbrush to get any hard to get areas, blew through the jets making sure they were clear) and got new plugs, but for some loving reason its still bogging down and refusing to start, if anyone on here knows about bikes, give me your thoughts
