Hi I've got a r304 shorty silencer for my yz125. I noticed it got quite loud. At a track which tests sound, i came in at 109 db. Which was 1db off failure. I've repacked it and this time I got 113 db. Any ideas why that is? As I remember I got about 3 full layers around the silencer core. Going to repack it again but just wondering where I'm going wrong. Or if something else needs tinkering. Cheers

May have packed it too tight.
