I just recently bought a 06 raptor 700 right now it's totally stock with the exception of a k&n air filter and pre filter. I have found a Duncan fat boy 4 full exhaust system that comes with a vortex ignition system for 500.00. My question is, is that a good deal, is that vortex ignition even a good thing to buy, or do i even need it. If i buy it how do i setup that ignition to my bike.. after spending 500.00 to buy this stuff i won't have the money to take it to a shop to have the ignition setup. Is this a good deal or should i find something else. Please help..
