For the record, 950SE
Jetting is H2W sans prefilter with snorkel, stock airfilter/airbox and 160/165 mains
Akras with large inserts
30C @ sea level
Nothing lost compared to prefilter setup gained a bit power on top of the rev range.
Moose, sounds like my experience with the K&Ns. Good for you. Ken's advice to me was that the bottom stuff should be close and the mains very lean. Exactly my findings and the bike carburated far better with a snorting pull to the limiter with the 170s or thereabouts. I expected to need to rejet everything over and over but the mains really did the job.
