What does Yoshimura recommend?
Yeah, Yoshimura recommends that your jet with the Dynojet jet kit. I have the jet kit already, just haven't installed it yet. I'll wait to the spring when things warmen up a bit (it's bloody -10 here!) to install the jet kit and then simultaneously install the yoshi exhaust too. thanks man!
