Out­fit­ting Three Dif­fer­ent Mo­tor­cy­cles with New Cams, Ex­haust, In­take, and Tuner

Hot Bike - - Contents -

You’ve heard the old chest­nut: “Your mo­tor­cy­cle is just a down pay­ment for the ac­ces­sories.” This def­i­nitely rings true in V-twin land, es­pe­cially in the horse­power and torque de­part­ments. Yes, fac­tory mo­tor­cy­cles are per­fectly fine, but were not fine with per­fectly fine, are we? We want more!

One com­mon V-twin u' rade is a new ex­haust s stem. But why stop there? There are so many more ponies to be gained from new cams and in­take as well. And of course, given the tech­no­log­i­cal ad­vance­ments of Har­leys and In­di­ans as of late, these up­grades re­quire a fuel tuner to achieve proper air/fuel ra­tios. We picked three pop­u­lar mod­els to test the power pack­ages we put to­gether: 2018 In­dian Chief­tain Clas­sic, 2018 Har­leydavid­son Street Bob, and 2018 Har­ley-david­son Road Glide. We then swapped out the fac­tory suck-blow bits for new cams, pipes, in­takes, and tuners and tested each on our dy­namome­ter. Over­all, we yielded some pretty nice gains. Hope­fully our ef­forts aid in your search for se­lect­ing per­for­mance com­po­nents for your bike.
