GS450t running bad

[Derezzed]

Hey guys I was hoping some of you had some advice. My bike bogs down when i pull the throttle. I was thinking it had to do with the choke because it only runs when the choke is all the way on and is probably not getting enough air intake for the fuel. Oh and i recently cleaned te carbs. Im gonna adjust the throttle cable tomorrow to see if that helps. Any help is appreciated thanks

here it is running in this video. 1/2 way through the bike starts running without bogging.

Are the carbs sync'd?
And did you mess with the jetting?
If it's only running with choke on I would think it's running lean, or clogged jets.

Was it running fine before you cleaned the carbs?

If that was a cold start, it's pretty much normal. Most bikes from that era take a few minutes to warm up and won't take throttle until they are warm. We have an FZR400 that dies if you open the throttle before it's warm enough.

If it runs fine once it's warm, I'd leave it alone.

+1 to Teazer.

You said the carbs were cleaned, but the pilot jets are really tiny. Sometimes it's easier to just replace them. Did you get new o rings for the carb intakes too?
