Jetting for 2011 xc300

[jeffs2200]

My new 300 is jetted pretty well for stock. It just seems a little rich on bottom when slow trail riding.

I figured I would drop the needle to lean it out a bit.

When I opened the carb this is what I found.

n1ef 1st clip
40 pilot
175 main

I am about 500 above sea level temps in the 50's.

Since I could not lean out the needle any more I switched to a 38 pilot. I only rode the bike up and down the road but it seems ok so far.

I looked at the spare needle that came with the bike, it is brass colored and I think it says CHN on it. It looks to be quite a bit leaner. I am guessing it would work well for high elevation.

What has anyone else done to the jetting on the new 300's?
