High Idle until Rev

[jinkside]

So after a week of taking my bike (450TX) out, I finally figured out something very strange: after normal usage on 40MPH roads, it idles at 4k RPM... until I rev the engine. I simply bring it up to 5k for less than a second and let go of the throttle, and it goes merrily back down to the normal idle of 1,100RPM.

I'm not sure how to search for that, but I did try. My best guess as to what's wrong is that it's... something... to do with the... float bowl? Maybe?

Sounds like a hanging idle. Have you replaced the orings behind the intake boots and even the intake boots themselves, if needed? Is everything else sealed up in the air box?

[Nessism]

Yes, intake boot O-rings would be my first guess. Check this list of other newbie issues to be aware of... http://www.thegsresources.com/_forum...d.php?t=171846

definitely a diagnoses of Hanging Idle. Follow the instructions given by Cowboy and go to the welcome page.

Thanks guys! I wouldn'tve have thought of calling it a "hanging idle" on my own, but that seems a more than apt description. Will I need to get a certain kind of boot for my 450TX, or are they all pretty generic?

Basscliff will be along later with his official welcome (might be best to post in the GS Owners section about yourself first) that includes a ton of information. In the meantime, check out www.z1enterprises.com for your parts.
