okay. uhm...it worked before winter. i havent ridden it for like 2 months. it started up a week ago but since then i havent gotten it started since. it turns over but when i release the starter theres a hiss of some sort sometimes. im thinking its the battery since its been so long and i just got my battery tender int he mail so i will charge it to make sure but it does turn over so.... but does anyone else have any insights or opinions on what else might be wrong. should i change the fuel? the tank is pretty full but the fuel is 2 or 3 months old.
