VERY high idle

[Mike]

Finally got everything back together and the bike is idling at around 5k. Moved the idle screw around, and it made zero difference. Adjustment screws all the way in made zero difference. I'm guessing it's running really rich, but I'm not sure why since it ran and idled fine just a couple days ago.

Did you replace the intake boot O-rings?

Check the throttle cable routing.

Also checck to see that it has not bound up inside the twist grip housing.
Happened to me once. It was feaky.

Yes, make sure cable is not holding throttle plates open- doesn't take much to have a wild idle!

not yet, but wouldn't that make it run very lean, not just give it a high idle?

Checked that, both throttle plates were barely open

Took both carbs out to check the bench sync. Both were completely closed, so I opened them up a bit just to check, got them even again, and still the same thing. Intake boot o-rings the next step?

Yes, classic GS problem...one of the most common. That's why I mentioned it in this and in your other thread too.

One thing I noticed with my '82 450E is that there are two locating holes in the throttle tube for the throttle cable.

When I was putting mine back on the other week, I had to move it to the second hole because the first one was holding the cable too short, sort of like what SVSooke posted the link about.

I checked the throttle cable and it's not caught up on anything. I checked the butterflies while the carbs were on and they were pretty much completely closed off

Cool, thanks. Ordered some.

I guess I can be thankful that it's supposed to rain next week so I'm not missing anything.

I'm having the same issue mike, and was just wondering if the o-rings fixed it, I already ordered some, but they haven't come in yet, and wanted to know if I needed to continue the detective work, or just wait it out :P
