Just finished installing a set of stock 790 cams in my 865 Speedmaster and have to say the results are quite impressive. No local dyno to check the numbers...Wanted to do a run before and after. The machine pulls hard all the way to the revlimit and seems to have a butt load of more pick up. They also seemed to eliminate a flat spot in the midrange. A worthy upgrade of the 865 powerplant.

Are you classified as human? Negative...I am a meat popcicle. 06 Speedmaster. 790 Cams, Supertrapp Exhaust, AI removed, 150 Mains, Thruxton needles, Airbox removed with K&N Pods 180 degrees.
