Perry's Bio

Harley-Davidson are pretty good at building "tunable" engines—they've been doing it for over 90 years. This Twin Cam is as "new" an engine as Harley have built in the last half-century, and its design is ideally suited to performance modifications.

Despite its improved combustion chamber design, the Twin Cam can still benefit from our Dual Plugging process. And speaking of cams, we have a replacement Cam Kit that will significantly increase power without losing that all-important low-end torque. (See my "Fun to Ride Guide" article.)

For a dramatic power increase without parts replacement, our Super Port Flow process gives great results on the Twin Cam.

Our replacement valve springs will reduce friction and heat buildup. Like our valves and pushrods, they're hand made from the highest quality materials.

For better breathing, you might also want to consider upgrading the Twin Cam's carb to one of our blueprinted Keihins with low-restriction air filter.
