I was looking at a Vance & Hines Exhaust system and a K&N filter for my 2003 Suzuki Marauder 800. It'll need to be jetted with these modifications, but I don't know which brands are good and what size to get. Any suggestions? I was looking at some Dyno Jet kits, and they have a Stage 1 kit that will work with the exhaust and filter. I was told that all I need is a screwdriver and some patience to rejet this thing.....does that sound right????
