I am getting borrowed bike ready to ride, and there are some things I need to get figured out before I take it to the woods. Primarily, I don't think that either of the silencers that I have are equiped with spark arrestors, and I have been told that the lawmen around here are pretty anal about that. What is the easiest solution? Do I need to buy a new silencer? If I do, is there one that favors low end for a 1992 CR 125? Would a new silencer require different jetting? Thanks for the help!
