ok i'm new here, just bought a 2008 ninja 250r. this is my first bike. But anyways i plan to put a yoshi carbonfiber slip on pipe, with the jet kit. i took off my stock muffler today and yeah loud as hell. i am wondering if i can just leave it off, just for the ride to work and back which is just a mile away from my house. I know that if i leave it off that it will make the engine run lean and run too hot. but will this be ok just for a one day type of thing at low RPM's???
