Won’t mess with the bike ?

[@lewismadeknifeandtool]

No. Look at all the Star Yamaha bikes. Cut airbuses are pretty common for race bikes.

Only a Dyno would show if it actually made a difference.

Thankfully many others have tested the results on a dyno, which is what inspired me to do mine. Look at all the Star bikes. 😊 But you don’t need a dyno to feel a difference. You can tell these bikes are starved for air, and cutting the air cover makes a noticeable difference you can feel even if you can’t see it on a Hp graph.

Yes. 304 Stainless mesh on Amazon.
