135s sounds about right for unifilter and drilled airbox. I had K&N, drilled airbox and 130s for awhile, then went full Freak. Check your fuel mix also. With the 07 you'll need to remove the mixture screw covers and either get the "D" tool or buy some after market mixture screws with nurled ends.
These are good.
