Hi all - my very reliable machine is having a problem. I went to take a ride last night and the bike turned over fine but wouldn't fire. Tried a few times, then put the choke in. It fired over for a split second but then just kept cranking. Battery seemed to be weak so I put it on the charger overnight, but still wouldn't start today. I'm not sure if it's related to putting leads on it the other night for a battery tender but even with a full charge on the batter today it just doesn't fire up. I have a full tank of fuel, the kill switch is in the on position, the fuel shutoff I've moved from on to reserve, so all that checks. Last summer the bike did something similar and there was a tiny rubber hose to the fuel shutoff that had come off, but that all looks in order right now. Any help on what to check next is appreciated.
