I usually ride up to Yosemite at least once a year and go right through Fresno up 41 north. I'll hit you up next year when it's warm enough to ride up there.
Kiwi, go for it and do cams while you're in there!

If you are going to re-use your stock push rods, there's more labor involved. If you would rather not bother with pulling the tank and going in through the rocker boxes, you will need to purchase adjustable push rods in which case, you can cut the stock ones off. I decided to re-use the stockers (since I was taking the tank off anyway) and thus, saved about $150. Removing the push rods was the part of the process that I had the most doubts about since I couldn't find a lot of info on how to do it. In most threads and how-to videos, they just cut them off with bolt cutters. Turns out it wasn't difficult at all.
Ill assume you know how to remove the tank and go from there.
Remove the six bolts from the rocker box cover and remove cover. This is what you will see once you've got the cover off.

Using a small flat screwdriver, pry the spring cap retainer off the push rod tube cover all 4 look to be exactly the same so I didn't label them. If they are not all the same, someone please let me know - although at this point, there's nothing I can really do about it anyway...
Next, you need to find TDC which was probably the hardest part of anything I did tonight. The manual says to raise the rear wheel off the ground, shift into 6th gear and turn the wheel in a clockwise direction (when viewed from the right side of bike). It was not easy turning the motor over this way! (Yes, I did remove the spark plugs
Once you've found TDC, remove the two bolts from the breather assembly. Depending on the year of your bike, you may not be able to fully remove the inside bolt because it will hit the frame backbone. I struggled with this for awhile because the Harley manual says to remove the breather assembly. (edit - looking at the manual again, I see that it says to "release" the assembly and not "remove"). I searched online and found that others had left the assembly on and removed it together with the rocker arm plate (next step) which is what I ended up doing. But you still must completely loosen both bolts or the rocker arm plate will not come off.

Remove the 4 bolts from the rocker arm plate follow the pattern in the manual. It says to loosen each bolt a quarter turn and continue following the pattern. This takes some time to keep turning each bolt a quarter turn at a time but Im assuming theres a good reason for this - probably so the plate loosens evenly? Once you've got all the bolts removed, gently pull the plate off. Youll be able to see the tops of the push rods.
The push rod tube covers can now be removed by hand with a little bit of wiggling. Be sure to remove the o-rings in the cylinder bores they will be stuck on there. You should have 3 o-rings per tube one on each end and one in the middle under the spring collar. Once I had everything off, I put all the parts in separate containers so I wouldn't confuse front and rear cylinder parts.

From this point on, you can pretty much just follow the youtube video that OkieNiteTrain posted. Like I said, I've watched that video several times to familiarize myself with the process. Its a very well done video.
When you pull the cam cover, this is what you see.

In the video, they dont remove the cam chain tensioner but I had to because the bolt for the cam support plate that is right next to it would not come out otherwise. And not having the tensioner made removing the sprockets and chain easier as well.

Before pulling out the cam support plate, you need to hold the lifters up. The service manual says to use modified binder clips and Im sure they work fine but Im a dummy and would probably screw that up plus I like shiny new things so I bought the magnetic lifter holders from Harley. You just plop them into the holes and the magnets hold the lifters up and hence, the name.


One thing I want to note when you pull the cam support plate, a little bit of oil is supposed to drip out. In my case, almost 3 qts came out! I think its because I did an oil change right before I pulled the tank so the oil didn't have a chance to circulate and thus, most of what was in the oil tank slowly came draining out. I confirmed this with the dipstick and flashlight the tank is dry.
So dont be a dummy like me and do an oil change right before a cam swap!
You can see that one of the lifters had fallen down. I just lifted it back up onto the magnet. Hope that's ok...
