Re: Backfiring and uneven idle

Pay attention to the idle mixture air screw. There is an "O" ring down in that tiny hole. You must remove it and all other plastic and rubber parts or the carb cleaner will ruin them. There are tiny passages in the body that get clogged up. Soaking is the only way to clear them.

This worked. I blew out all the passages with compressed air. Checked float level. Reassembled carb. Installed and really tightened hose clamps holding the carb. Like new bike now.
That's encouraging . Did you have to buy a rebuild kit? Or were you able to replace all of the rubber parts?

Uuuuh, :oops: . I didn't actually do it. A friend of mine did. Hope it didn't mess anything up :puke: .
