I have an 87 KDX 200, need to replace the stock silencer/arrestor, it weighs a ton! I can't find a combo silencer/spark arrestor. I have found a silencer without the spark arrestor, DG makes one, but I ride in the woods in Oregon, it's required here & I don't want to have to purchase "Sparky" (fat pipe spark arrestor you add to the tail pipe). Any ideas?
