I know that this has been discussed here before, so be nice to me for not searching. Besides we need more action in this group anyways. Right attatoy? Now to my question, I just cleaned the carb on my 95 XR600, and the needle clip is on the 3rd slot from the top. I do have a small bog off ilde or low rpm. If I understand right you move it up on notch to get slightly richer off idle. However, I think I remember a post that says if your over the 3rd notch you need to go up one size jet. The jet I'm runnig is a 152 and I ride anywhere from 6,500 to 10,000 ft. The plug looks real good. Just a slight touch of black. Sorry for the long winded post, but any help will be appreciated.
