i was driving my bike home from work and made a stop. when i got back on the bike it made a popping sound almost like a backfire but it wasn't even running at the time. i looked down and the hoses that connect the carbs to the cylinders were disconnected from the carbs. i reconnected the hoses then started the bike back up. ran fine for a second then made another popping sound but a little different this time. it started making a loud rattling noise and i babied it the last few blocks home. now it won't even start. all it does is make a clicking noise like a car with a dead battery but the battery is only 2 weeks old. any ideas?
