Les, I saw in one of your previous posts that you went up one size on the mains that is why I posted the questions. Did you go up a size because of the full exhaust+K&N? I was thinking I will be ok because I have stock airbox and punched factory exhaust. Nick57 seems to agree. Thanks so much for your replies guys, I always hesitate to change anything when it is running so good but tired of the expense of filters, they are around$32 at dealer here now. I can get them cheaper online but would just like to go with K&N and be done with it.
PEACE and BLESSINGS
