Hello everyone ! New to this forum and new to owning a dirtbike. I ride street bikes street/track Yamaha R6 and a ZX10R . I decided to buy a 2012 Yz450f to have some fun on the bad weather days and improve street riding also. I just bought my 450 on the 1st of January 2016 and when we tested it out it ran fine and strong . Brought it home rode it up and down the street the next day and rode fine. Always turned on on the 1st to 2nd kick . This morning I went to turn it on to warm it up to do an oil change for it to have new oil . After it turned on after a couple seconds with the choke on I turned off the choke reved it and on the 3rd Rev it shut off I can only assume it was cold still . When I try kicking it back on . On the 3rd kick it made a sound like mettle to mettle a bit , I went to kick it again the the kick start was completely jammed it will not kick no matter. what . The tire moves in Neutral but if I put it in 1st gear while holding the clutch it does not move at all ...... Any help of ideas will be appreciated. I have no clue what happened .
