I've always thought I had issues with my carb cause my bike won't idle but yesterday I realized I had it all set right to the best of my knowledge. I have a 2005 YZ250F with 290cc big bore. I had the thing idling in my driveway for 10 minutes. As soon as I pop it into gear it idles for maybe 10 seconds and stalls. If I put the bike in gear and hold the clutch in and spin the wheel, it's pretty stiff and hard to do so. I have very slight slack on the lever adjustment. If I tighten it up, it doesn't seem to help. I have no clue how to adjust the bottom portion of the cable, or how to properly do it. Does anyone know how or have a good guide I can follow?
