Hi everyone, Im new to this forum so go easy on me. I have an 1982 TT550 and it has an old 80's style 4in supertrapp system, and I was wondering if anyone has tinkered with their XT exhaust before? I would like to add an open end cap to my system but Im not sure if itd be to lean. It currently has 8 disks and the open cap acts like 10-12. any advice would be greatly appreciated. Also if anyone messed with the jetting on these bikes, how hard is it to rejet? Thanks!
