sorry i have no clue...but did you try asking yhe yamaha dealer about that????They just might know.

 

If you just change the filter, you should not need to rejet.

 

I agree. It would probably be ok. You are putting in a high flow filter, but not really giving it more air. In a closed airbox they probably flow about the same.
