That's close to the same elevations that we are running here. In the summer we run a 172 main, n3ch or n3cj needle in the 2nd clip position and a 40 pilot. In the winter we bump the main to a 175 and lower the clip to the 3rd position and bump the pilot to a 42. I have found that temperature and humidity have a lot more affect on jetting than elevation does.
Another thing that really plays a part on jetting is your air filter oil. I remember back 30 years ago when I was working at a local Honda dealer you could always tell the guys that were using the old Bel-Ray filter oil. Most guys just used motor oil back then so if you switched to the Bel-Ray filter oil you had to drop the jetting or else your bike ran like crap.
