[QUOTE="stormer94, post: 207111, member: 23528"] I've owned like 50 bikes, I'm no rookie. I understand that the new yz250f requires a different technique. So I read the manual back and forth. And feel I have a good handle on it. I'm still on the first quart of gas mind you. I got it to run yesterday and I ran it for about 45 minutes. This Morning I tried to get it to run, and it took about 10 minutes of kicking to get it to go. At 2:30 this afternoon I thought I would go home, ride till dark and that would be about the end of it as the snow is about to fly. I kicked that thing from 2:30 to 4:30. 2 HOURS!!!! :ugg: I suppose on a purely exercise related case I got more bang for the buck than if I had actually ridden it, but that's not gonna last forever, I WANT TO RIDE IT!!! Here's the drill. It's got fresh gas in it. I check and also turn the gas on. It's about 50 degrees outside, but nice. I pull the cold start lever and kick until I get the compression stroke...NOT the exhaust stroke. I pull the decompressor until the kickstarter moves about 20 degrees (let go of the decompressor), let the kickstarter return and KICK. (repeat for 1/2 hour). I'm taking great pains to see that I am not accidentally cranking on the throttle by even going so far as to put my throttle hand on the crossbar so I can't accidentally flood it. I decide that maybe it needs cleaned out or something. So I pull the decompressor and kick it 20-30 times with the hot start button out and the cold start button in. Repeat kicking for another 60 minutes... :scream: with a few random minutes where I would take some time off and lay on the ground wheezing... At the 90 minute mark, I check the plug... It looks like a plug, not wet, slightly black. I put in a new plug (an interesting ordeal on it's own). Repeat 10 minutes of kicking and me hunched over the bars, wheezing and then finally giving up... (insert total disgust). I very carefully push the bike back in the garage with what little strength I still have. I really wanted to beat it with a sledge, but resisted. I maintained my calm and here I am asking for ideas. I've decided that maybe the gas I put in it is 87 octane. The manual says 95. So I brewed up a batch of 95 and am about to drain the gas and try that. I can't imagine that is the problem, but I'm willing to try about anything at this point. Other than that, I'm stumped. Maybe I need an exorcist. :( I'm at 2200 feet in elevation if that matters. My back hurts, my right foot and leg are KILLING ME. :ugg: And when I'm done stuffing this bike in somebodies ARSE at the Yamaha shop I'm gonna feel a lot better. Any ideas... Anybody? [/QUOTE]
