2006 kx250f carb tuning HELP!

Hey guys, i'm new to the whole 4-stroke thing, been riding vintage 2-strokes for the last 20 years. I just bought my bike and the carb needs to be tuned. Can somebody give me very very detailed instructions on what to set ALL of my screws at for an altitude of 1000 feet with a riding temp of around 70-80 degrees. please the more detail the better and when you're explaining everything pretend i know nothing about carb tuning. Thanks in advance!

Not sure if you've gotten this taken care of or not, but looking at the service manual should give you a good idea of what specs you want to tune your bike at. Depending on how long you've been riding it, a good cleaning couldn't hurt since you're already taking it apart.

You can use this manual to get the specs you need, along with very detailed instructions on how to take it apart.

If you have a jet kit installed, then paperwork that came with the kit should specify the positioning of the needle, and the number of turns your idle screw should be at. If your needle is stock, then you shouldn't be able to change the positioning on it (if I am not mistaken) and you'll just need to adjust your idle screw. In my opinion though, it is much easier to adjust the screw once you are at the location you'll be riding at once the bike has warmed up and you are able to actually hear the exhaust.

Should you take apart the carb, if you haven't done it before, just be patient with it and take your time. There are plenty of little pieces that you can not put back together right and have the bike not start entirely, then you'll have to take it apart and start over. It is tedious, but once you do it the first time, the second time will feel like you've been doing it all along.
