.....saying that it ain't so easy to install them on the new twin cams because your bike already had the good Timkin bottom end, where as these new bikes got rid of that and have bunch of slop that the cam tensioner compensates for.
Crank run out has to be careful measured before knowing if your bike is ready for gear drive cams.

Going gear drive has more benefits than just eliminating tensioners. They also allow more accurate timing and less resistance, since chain and tensioners are gone, which ultimately frees up more ponies.

Looks like you're all set Stilup! This is actually one of the most rewarding mods to do on your bike, because the payback is sweet
