EVO cam/gear swops ???

Bring it on. ...... violence is good

My EV27 cam was fine with the gear it came with, I didn't change over. Although I understand the reasons for swapping, I do doubt the need to do it as if it is essential.

the problem is, if you don't have,or know how to use the measuring device you have to fit the cam to find out if it does fit. Have fitted a few that whined real bad and always do the gear swap as its guaranteed to work and takes about as long as measuring the gears to do the swap and a lot less time than pulling it apart again.

Spanners do you plan to cut the push rods and do adjustable rods?
Can't find a good how-to for this work (thought it seems pretty cut and dried) so I'm eagerly awaiting your how to.
In case I get froggy and decide to embark before you're done, how do you collapse the pushrod covers? The rest looks very straightforward. Not looking forward to removing the 1995 exhaust though...I can foresee broken bolts in my future....

May be a dumb question, I have swapped out exactly 1 EVO cam, but how many cams are out there in motors with a retarded or advanced cam timing condition as a result of swapping out the manufacturers gear installation? I would think the only way of guaranteeing a proper gear swap would be verifying it with a degree wheel. Does anyone really do that? Eyeballing a couple of scribed lines just doesn't give me a very warm and fuzzy feeling. Fortunately, I own micrometers and thread wires so it was a lot less trouble to verify the correct pitch circle instead of carrying everything to a shop with a hydraulic press to get it "close enough". Had my measurement not matched, the service manual lists the matching pinion gear for the measurement and it is keyed with loctite and a nut.
I come from a hot rod background and used a degree wheel on plenty of cam swaps and never found one to be off. I know, different animal than a Harley, but manufacturers are pretty accurate with their cam timing.
Just asking, flame on.
For grbrown, I thought y'all called them knocking or flogging sticks.

Ok. In reverse order, the gear swap is as accurate as it was when it was done in the factory, they use scribe lines too. I have every confidence in my abilities to get it right. Don't over think things and get hung up on data.
We won't be using adjustable push rods because a: neither of us believe they are anything but a retrograde step and b: we are doing the rings so they won't save any time.
To collapse the towers you flick out the keepers at the top and using some pipe wrenches or just your hands you push the aluminium section down into the chromed part.
