Appologies for absence ... bike delivery put back from Feb to mid April by HD.

I keep trying to understand this gear driven cam thing. I fancy a set-up that includes Woods cams but that requires gear drive. I have downloaded the S&S PDF as they seem to be the people to use for the gear drive. However it infers that there is a need to re-machine the cases to accept the S&S gear drive. This might be testing the capabilities of the UK dealer network so will probably put me off.

Have I got the right end of the stick on this one?

Tony,

Ask your head mechanic, Who is the best machinist that I can use for this and what do you think about how much time is involved to do this. You can then figure out the hourly rate for it. Usually they will send you to a guy that can get this done for you straightaway.  You are absolutely correct about getting gear drive as the best choice. Don't be put off buy it.  Schedule your appointment for tear down, machining, re-assembly and dyno time for tuning.

Good to see you back Tony.  And sorry for the delivery delay.  Did the bottom end repairs on the "old" bike finally get taken care of?

Tony, I think that you certainly can get this done.

No machining nessacary!! maybe a little grinding depending on cam lift!!! S&S owns the patent for the Gear Drive however andrews manufactures it for S&S so no matter where you buy it it will be Andrews/S&S system. About 75% of all the aftermarket cams out their are manufactured by andrews (trust me this is a good thing andrews makes a quaility product) [smiley=1syellow1.gif]

Nothing "dictates it" some believe it's just a better system then the chain driven cams. In theory it is, less moving parts and no chain tensioners to wear out, the trade off is noise, some say it is noiser. According to EPA standards it is noiser and that is why the factory doesn't offer it. [smiley=1syellow1.gif]

I see.  Is this something that you would do on a 'stand-alone' basis, or wait 'till other engine work (like cam chg.)?

[hd-dude]

If it ain't broke...Don't fix it. That's my opinion. I'm sure others here will feel differently. I have the 7 year warranty so if they wear out I know that I am covered. If you are changing cams then it makes sense to upgrade to the gear drive setup

Spy,

Gear drive set ups are for gear driven cams.  Chain drive set ups are for chain driven cams.  If you are thinking of doing other work, you may postpone this.  If you are doing research or have a progressive build that will entail the use of several different cam setups through out the process of ultimizing and optimizing the performance, I would do it now.  My answer is not meant to sound obscure.  I like gear set ups for cams as a personal preference.  I do not have a clue as to what you are looking to accomplish and can not advise you without knowing that.

Mike, the only reason I was inquiring was relative to "dependability" or "efficiency".  I'm not pumping the motor up, completely satisfied with the way it's running now.  Fast enough for this skinny ole dude.  Although, I'm wondering what to do about my 80 ci Evo.  I was gonna do the Factory Re-Man Program and get the good deal financially, new powder-coat, one-yr. warrenty, etc. for $2500 turn-key in a couple of weeks.  BUT, now I've gotten used to the 103 torque and wondering if I should go a different route w/ rebuilding the Evo.  ??   what to do??    [smiley=confused5.gif]

That's a horse a piece. I would probably keep it a reliable old stocker and let it be.

I have a 02 SERK with the 95 inch. My homework has told me that I have the SE203 cams. My mechanic just showed me what can happen to the "shoes" on the stock setup after 15 to 20 K.  And it aint pretty. Does it happen everytime? NO. But if those parts wear thin and disenegrate it will cost more then the $1000.00 or so it would have cost for gear drive.  Plus the timing of the stock setup can be off by a 1/2 a degree.  

So with that, I want to put in a gear drive. But what cams to use to replace my SE203. My guy likes Andrews, others like S & S .  And what grind ? can I go to 570 with the stock heads? .  And is lift everything?.  These are the questions I'm faced with.  Any feedback would be helpful.

the gear drive cams are a little noisier with little or no gain in performance. the weak link is the chain tensioner shoes that ride upon the cam chain. mine were worn beyond limits at 25000 miles. there is no need to clearance the inside of the cases unless you use a very high lift cam. im running the andrews 37g with s & s gear drive,delkron support plate.feuling oil pump and lifters. great cams not too much. its an easy install and i have the tools. this was done on my 2002 fxstd [smiley=xyxthumbs.gif]

Well I was just going to set back and read but I do have a little info that might help(stir the pot)

The chain drive is not accurate( for valve timing) as previously posted. If fact it can be off by as much as 4 degrees. If you are looking to make consistant power this is not good and the gear drive is the only fix for this. As far as cam selection goes if you are looking for torque numbers you are looking for high
