I just picked this bike up last weekend. Rode it about 150 miles and then put it in the shed for the week. I take it out today and it wont start. Im sure its in neutral, the ignition is in the right position and the lights all come on, the engine cut off switch is in the right postion, and Im pulling in the clutch as well as tryin various degrees of choke. When I push to start nothing even happens. Any ideas?
