Hey everyone just wanted to say Hey and that this is a great site. It has helped me alot, so my hat is off to all the moderators and the Techs. that are in this site GOOD JOB My son and I just got some bikes 05 TTR125 for son and TTR250 for me and we love them. I am in the process of re-jetting the 125 and have installed the R4 WhitBrothers pipe. For my 250 just a slip on T4, what a difference.
