Hello all new here, I have a 450r 2004 with yoshimura trs can on it. Was runnin great but was extremely loud so I thought I would repack it. I opened it and was next to none of any form of packing, I thought very odd anyway I repacked it. Also bought an T.E.C insert for trs exhust-tec-sb-a. Installed it and know I get at quarter throttle a hesitation and then it kicks in. Could anyone point me in a direction?
