I've run this cam in 2 bikes.. One was advanced 2, 88 ci SnS evo create motor, another is a 95 ci road king.. Still have the road kink.. I would expect that it works well at about 10.2 to 1 and would provide a nice power band.. I'm running 10.8 to 1 and it can ping a bit when the temps get over 100.. Not sure about the chain driven version but the gear one rattles the valve train at idle a little when the motor is hot.. Running down the road sound is good. Gears are tight.. In the 88 ci evo the cam was dead quiet. Cr was about 9.2-9.6 to 1 in it.. Worked real well there with staggered dual cycle shacks on a softail..
