Motorcycle Repair: torque cones, head quarters, head quarter

Question
I have a road king with head-quarter heads and cam it has been dyno tuned and runs good, i would like to know if torque cones would make a difference they look like they would restrict the flow more than anything.

Answer
your right BOB thay are a wast of good money and will also KILL HORSEPOWER and TORQUE. I tested them on my dynojet 250 dyno on meny bikes.and then I tossed them in the trash can where they belong. Install a set of white brothers E-Series 2 into 1 headers and gain 10 to 12 horsepower and 15 ft lbs of torque over any exhaust system you have on your bike now. and this gain is from 2000 rpms to 6000 rpms accross the entire power band. The head quarters cam is the best bolt in cam on the market for evo"s but not the best cam there is!!   JOHNNY 602-705-7474
