I concur. And on top at that Zat has a 1198 motor in the bike which makes it even more difficult to silence without killing top end.I haven't run at Laguna on a 999 in a decade. But, from what I remember, the db killer alone didn't work. But then again, I ran a big exhaust back then.
I have a suggestion zet. Find out where on the track they measure sound and not peg the throttle there. This works for me . Alternatively. It may be simple to mechanically restrict the throttle opening which will shut the thing up and is less fucking around then making and trying bits that that clog the exhaust and kill power anyway.
How’s the bike been working for you? No problems?
