Gear drive cams

Just read article circulated by J@P Cycles regarding spring cam tensioners and hydraulic cam tensioners and the poor design by Harley and the inevitable failure.They suggest gear driven cams.Just looking for secondary opinions on this topic. The article implies that hyd cam tensioners as I have in my 2010 FLHTK merlot and cherry sunglo,s/e hi flo a/c , s/e super tuner,v/h power duels,monster ovals and s/e compensator fail at the 50000 mile mark.What is the cost of this conversion . Thanks

Your hydraulic cam tensioner is very good. You put in gear drive for around $1000 plus you better make sure your crank has .004 play or less. Then thats several hundred more ! You really don't need to worry about it. IMO

If adding gear drive cams check the run out on your crank and ensure it is under .003. Supposedly you get more power with a gear drive cam than the hydraulic tensioners. I have the hydraulic upgrade on both of my bikes as t hey are both 2002. No issues yet. One has 75K and the other has 40K.
