xr650r is the bike Just purchased the Baja Designs Baja Baffle and the HRC Spark Arrestor from Baja Designs. Using the OEM muffler. Two problems: 1. The 3 holes for the spark arrestor that should align with the holes in the muffler are close but don't align perfecty. (There are 3 screws that hold it on) The stock sparker arrester that was on the bike aligns perfectly. Has anyone else experience this? I'll have drill out the holes slight if I want it to work. 2. The baffle that goes inside the spark arrester does not go in easily. In fact, I don't see how it's going in all the way without major hammer action. It's that tight. Has anyone else had experience with this setup? Any suggestions appreciated. I almost wonder if they sent the wrong parts?
