    maybe a little more information might help...year, temperatures, altitude, riding type, etc. Also do a search, there have been too many "jetting" threads to mention.

    Here's what I'm running in my '02 250
    Sea level 40-55 deg F, MX only, some Sand.
    30-73 2nd or top clip
    35 pilot
    410 main
    air screw stock +- 1/4 turn

    As you can see way richer settings than stock. The bike is stock. The 02 CR will scream up on top when you richen it up, it's like a different bike. Riding in the sand requires a rich setting too. The only battle is having a clean bottom end. I will never run anything less than a 400 main even when it gets to 90degF. I just change pilot back to stock and play with differnt needles and clip positions. I think if you start with limiting your main jets to a couple and make that your starting point the bike won't lose that top end. I've heard talk about running a 4.0slide (4.25 is stock) and also changing the brass part the needle goes into from an s9 to an s8. Not much help here, anyone?
