I expected to need to rejet everything over and over but the mains really did the job.
Finally I chickened out with the K&Ns Navin and went to the original airbox and snorkel. The rear intake positioning does not allow a clean solution on the SE due to the proximity of the seat pan and filtering surface area becomes problematic. But I had a couple of ideas for an alternative airbox which I will revisit later in the year.
