Ok I got my 1st motorcycle last fathers day. 2005 America I have removed the secondary air intake, added new pipes (no baffles), and put in a K&N filter.I am not a mechanic but this was all easy to do.My question is should I do the rejeting or have a mechanic do the work?(money is a problem) I think I could do it myself but I don't want to screw in up and have to pay more to get it running again. Is this a easy job also?
