1st Question - What is the prime operating RPM at WOT?
2nd Question - If I remove the resenator out of the airbox will I lean it out?

Thanks for your help

I think the prime RPM for the ZR 800 is something like 7400 RPM, pretty low.

Hey Jamie, i believe the ZR 800 should be around 7400-7600 r.p.m. I tried removing the shelf and then the air horns out of my old 2001 ZR800, plugs looked fine afterwards but no performance improvement, just a lot more intake noise !!

Dont mess with the airbox on the efi
