Yeah I did all that. I found out the red knob is an after market air jet. I think its an issue with that.

The red knob is on the carburetor not the the handle bars. There is also a little lever next to the clutch. I think ought that was a compression release, but after reading some of these threads I think it is a hot start lever. The guy stored it because he got into car racing. Said it ran like a top when. He parked it.

I just bought a 2003 wr450 that has been sitting four the past 4 years. I bought a new spark plug and cleaned the carb and jets. I kicked this thing all day and only got it started 4-5 times but couldn't keep it running. The electric start doesn't work. I've read up on in and was told by the previous owner it is z factory defect in this year and model. Is there a trick to stating this thing. Every time it did start, it was shortly after I messed with the red knob on the bottom of the carburetor. I think its the hot start knob. But I think I have a jot start lever. I don't know. Any help would be great. Thanks.

Hello everyone. I'm new to this forum and have a question. I've owned dirt bikes my whole life and just added another to my list of bikes that I've owned. I just bought a 2003 WR450 from somebody who told me it hasn't been started in four years, in storage, they also told me the electric start doesn't work, no biggie, so I bought a new plug and cleaned out the carb. I kicked this thing literally all day and started 4 times but only briefly. Is there some kind of trick to starting these things? I've never owned anything this new or big. Also is there two hot starts. I have one on a lever and one red knob. The bike only started after I messed with the red knob. Thanks.
