Hey guys, so I need to change out the stock exhaust cap on my 2012 Ktm 150xc. The first race of the year is this weekend and it requires a spark arrestor. So I went ahead and ordered one from enduro engineering. For some reason this never crossed my mind, but I noticed today that the cap is only held on by rivets. I've never worked with rivets in any way and have no idea where to start when dealing with them. So if you guys could tell me how to take the rivets out, and re install them with the new end cap that would be great! Thanks!
