I think 35's should be plenty big enough unless you are planning a all out drag build.

35mm pwk will compliment that motor nicely. stick with the 35's.

You'd gain maybe 2hp with 39mm carbs but if you are duning or other riding the 35s will have better response and be better everywhere but at max rpm.
