it wont hurt ur engine......... u can adjust them to give you more power at certain RPM's....... and on the vortex........ it has a handlebar switch for 2 different settings and u can make one of them be for the holeshot....... then when u get goin....... flip the switch for mid-range :rock ........ its pretty cool....... and the Vortex will raise your RPM's to 11,700 instead of 10,750 :rockOriginally posted by CTYfzrider@Oct 5 2003, 09:16 PM
I would like to know what these do for you? do they get you more grunt and power or something? is the vortex worth the buy and do they hurt your engine at all?
