You are going to need a fatter pilot. I run a 68 at sea level and my bike is mostly stock. I thought that a 62 was the stock size pilot, but I have a 93 and it might have changed a bit over time. You might need the clip one up from the bottom. The middle is stock.

I hope that you don't ride in the dirt with a K&N. In my experience they are OK on the pavement, but let too much dust through in the dirt.

The only way to know the best jetting is to experiment.
