Hello everyone. So I bought my first dirtbike yesterday, its a YZ400 and when we bought it (actually my dad did) and according to him it started up and worked and everything so he took it for $1550. So I tried to start it without any luck. I tried everything, choke, no choke, hot start, no hot start, but no luck with the kick starter. Finally I got nit to start by rolling it down a hill and releasing the clutch at the bottom, but the bike wouldn't idle so I had to rev it constantly just to keep it from dying, even when it warmed up. Eventually I couldnt even start it by rolling it down the hill. sometimes when I try kick starting it, it will backfire but thats it. Any ideas? and is 1550 for a bike like that too much?
