Ok, The last bike I had was a 95 CR 125, that I sold in 2000 I havent had a bike since. This weekend I bought a 98 yz400f for myself and a 2001 xr100r for my wife. anyway, to the point. The yz hadent ran in about 4 months. The guy I bought it from said it was "running lean and backfired a little." I got it home and kicked it for a while with no luck so I pull-started it. I ran it for a while. after it was warmed up it started 1st kick no problem. I put it in the garage for about 48hrs. when I tried to start it, no go. Now I'm totally ignorant to this bike so excuse my dumb questions. but what am I doing wrong? The bike has a compression release. also what is the other thing that looks like a second choke?
