Welcome from KY! Sounds like a sweet set-up - would love to see pics if possible.
As for the oil issue, I believe the older (pre2007) 400s use a bit of oil when running high speed WOT on the highway. Just keep an eye on the sight glass - check the level every time you fill up the tank and top off a bit if need be. You should be good to go.
Ride safe!
