Install on the camshaft was not bad at all and for someone who just started working on bikes this past year its very easy (just dont strip your valve adjusting nut like i did in the process…LOL). I can get up small hills with ease now in 5th gear, unless they’re tall hills you still have to downshift. The noise this cam makes and the growl it gives your bike is INSANE. It sounds amazing even with an amazon exhaust!! Getting this cam made me have full confidence in DHM and i really want to do the full 149 big bore next! The DHM team was also very accommodating, as my mail in ECU was taking forever to arrive to them so I asked if I could be sent an ECU instead so my order could get shipped sooner and they did it with no hesitation. Thanks!!
