i have a 2000 heritage and i am thinking of changing to gear driven cams to eliminate the cam chain tensioner problems, bike has under 20,000 ks and i have had no problems with it but after doing a bit of research it sounds like i might have a few dramas in the future. my question is what sort of $$$ will i be up for to have the whole job done ? and is the gear drive the way to go ?
This may give you some insight into whats involved.... I'm happy with mine..

Wozza how many kms had your bike done when you swapped over ? i have talked to a few blokes who reckon that the tensioners only become a problem when they have done more than 50-60 thousand kms. like i said mine has only just turned up 20,000kms as the previous owner had it for ten years and only put about 12.000 kms on it. I am running mobil 1 v twin with services done at 4000 kms. Am i being paranoid or is this thing going to shit itself sooner than later ?
i got a 2001 dyna, i've had since new, after having to change three sets of tentioners ( inside & outside ) then having the third brand new genuine HD outside tentioner fall apart one week latter & counting myself lucky all the parts were still in cam chest, not going through my motor. i went to gear drive, i had Andrews 55 chain drive & went to andrews 55 gear drive, not one HP or one foot pound of Torque in it it dynoed same HP & TQ gear drive as chain drive. but 7 years down the road i'm still happy i went gear drive.
mine had about 30thou on them... & they were'nt too bad... BUT as TooBadd said... they can go at any mileage...
have seen them completely stuffed with chips ripped out at 10 thou..
The hydrolic conversion is a little more costly but it is a excellent replacement..
I decided to go gear drive as I knew what cams I wanted, & dont have to ever worry about cams or adjusters again..
NOTE: make sure your crank runout is with in spec's for gear drive FIRST...
My tensioners were fine after 30k, and I just replaced them with new when I did Cams. The thing you should be worried about is the Cam bearings. The '99 and '00 had issues. There is an updated front outer roller bearing. My inners were OK (replaced anyway) but the outers had spun. Pics of old tensioners here:
