I have an 01 wr426 with a gutted factory pipe and the air box lid removed. It's fast bey much too loud. I also have a GYTR silencer insert for the pipe that I want to know what jetting would be best for this set up. I just bought the bike and I don't know what jet it has right now, so maybe someone can recomend how many jets leaner I might need to go if I put in the GYTR? Thanks in advance for your help.
