jetting w/ K&N - Raptor 660

[ReignMan22]

I am currently running the stock foam filter with half the lid removed. I am using the suggested 150 left/ 155 right jetting that came with the full exhaust system. I was just wondering what you recommend for jetting once I go to the K&N Pro-Flow kit w/ no lid. I am assuming I will need to bump the jets up one and then fine tune the air/fuel mix and such from there. Would that be safe to assume???

Yes, use the 150/155 as a baseline to tune to your location and conditions.
