I removed the exhaust servo cables from the stock can. When I installed the muffler the butterfly was open. I didnt check to see if its spring loaded so that it stays open or anything and was wondering if anyone knows.

the spring is loaded so when the bike is started the servo keeps it closed. otherwise its open

it is my understanding that this "valve" was also in place to help with low-end torque. that would mean that keeping it open won't do much good unless you're on the track or riding very, very unsafely.

someone please chime in if i am mistaken. it wouldn't be a first for me...
