Used 2008 yz450f

9 posts in this topic

Hello, I'm new to this forum and just getting back into riding dirt bikes coming from mountain bikes. I just bought a used 2008 YZ450F from a guy. He said that he hasnt ridden it in at least 7 months and the fuel is old. I ordered new decals and brakes for it and got them in today. I got the decals on and had to leave work. I had it in the truck and met my mountain bike buddys for beers and bond fire. At the end of the night I started the bike up and let it warm up. The pipe coming straight off the engine was red and orange in color like it was burning hot. Do i have a bad engine? Effect of old gas and oil? Jetted to lean? What should I do? Thanks so much for your input! Sorry if grammar is bad, Ranger IPA tasted good tonight :lol:

Thanks again!

That was your hazing. Laugh it off. It's normal, but everybody freaks out the first time they see it. Read: http://www.thumpertalk.com/forum/showthread.php?t=236304

Ditch the gas, though. :lol:

Thanks guys! I'll defiantly take the hazing! I was thinking I had much bigger problems. I've been worried about buying a used 4 stroke and that just freaked me out. Since I do have a used bike should there be anything that I should check before I go ride hard?

Thanks

It scared me the first time too! They all glow but you can only see it at night or in a dim garage. I think i started a "glowing pipe" thread on here at one point myself.

Pour a little Seafoam in your first tank of gas. Cleans up stored bikes pretty nicely on your first ride.
