Benmb, sorry I've been out of the loop for a long time here. I did have my original air filter connected straight to my carb, I had to get a little creative after my aftermarket air filter came off and was smashed by my back tire. I don't remember my jetting right now but I'll try to take a look at it soon and get back to you.

Goose, sorry to bother you.. your pics show the stock filter directly attached to the intake pipe? Do you still have it this way? Jetting? I am steadily 'bobbing' my gz, and looking at all the air filter options, any info would be major help.. thx, benmb
