That is what they all do. I have seen it on everyone I have been around. It happens because there is no air moving past the pipe & it cools immediately if you start moving so don't let it sit there. It is better to warm it up by riding it EASY anyway. Mine does it with a Yosh full system, Pro Design air kit, & a Dynatek F.I. module. Since you did change the air filter I HIGHLY recommend you get an F.I. programer. I love my Dynatek! Ray.
