Simple job just take your time and FYI 99% of the time the gear on the new cam is fine don't overthink it. You'll lose a ounce or two of oil when you crack it open, old cookie sheet works well. Only things to really watch is changing the inner bearing and adjusting the lifters.Use a lite touch going out then back in with the cam bearing, be sure it starts in straight and lube it a bit. New lifters I soak in oil overnight so be sure to let them bleed off properly before you move on to the next pushrod, sometimes guys get impatient at this point, don't.
You'll do fine.
You'll do fine.
It has already been used to running with the pinion.
They are a married set.

Shovel days very much so as they tended to be all over the place spec wise but I've found the evos had much better consistency with sizing on the cam & pinion gear sets. Andrews does a very good job of getting that right out of the box. Lastly the average do it at home guy is going to have no way to mic out much less swap gears on cams so why even bring it up to a first timer ? I've yet to see an evo cam swap chew itself up right out of the box. Think I've replaced exactly 2 pinion gears to get a matched set in all my years doing this.

Nope solid advice, S&S steel breather as a replacement, seen that plastic gizmo eat a lot of bores.

BB.No8, I agree with you as well.
It’s one thing rebuilding an old motor with parts that have been working hard together in unison. Than adding a new part that is off spec one way or the other.
Some parts are better if not mating with foreign ones. This is metal

metal. Math on math. Combustion needs logic. Not emotions

For my logic as I have BTDT it is simple
Keep the fit as it was.
A new gear will be a gamble if it is correct or not.
I am sure a shop will press it on / off for you for a minimum charge.
It only takes maybe ten minutes.

No one near me who I know of that does this stuff, so I'm on my own pretty much, heh. It's the one bad thing about where I live. Hell, *I'm* the one people come to to help fix their bikes...wait, *came* to...I sold the twin cam 2 years ago, so I also sold off all those tools for it, lol. I'm on my own now as all the people I know that ride, ride new. I'm the only one with an old bike on the road.
No indie's anywhere in these parts that I trust. Went to the one and only I found, just to have a new tire put on the front. They snapped one of the bolts holding the fork holder on the bottom of the right fork. Luckily I was standing there and they were able to fix it. The only other closest I know of is over 85 miles away, and the only vehicle I can borrow gets me 15 mpg...I can't afford that.
Steel breather gear is $90 for a Made in America (I try as hard as possible to never use/buy anything else) S&S. We'll see after I pay off the bills first thing at the beginning of the month if I can afford one.
Appreciate the hints and encouragement folks!!
