Yep, intakes suck faster than exhaust.

Not sure of the hours on my Beta (have not scrolled through head unit) but it has over 5K miles so I would estimate over 200 hours.

Zero adjustments on the ex, one on the intake so far.

Only have 2 hours on my 17 WR250F. So don't have any data.

Maybe the guy with the 4 stroke yamaha 250 and 450 will chime in.
