Sticky stuff leaking from cam chest area
Did not notice year or model but you are in the EVO forum and it appears to be an EVO motor.
The Original Factory units had a beige sealant while the replacement harley unit has a black sealant.
The original melts as shown sometimes after several years and this commonly presents with hard starting.
Lots of cranking, then more cranking, then more cranking....then you take a break for a minute or two and a light touch of starter button allows motor to come to life.
Your bike is most likely carb since the TWO screws are in the adjustment slots.
The fuel injected bikes had a fixed timing from factory in the round screw/post holes instead of adjustable slots.
There was an issue with aftermarket CAM sensors not being compatible with stock cup for EFI but your bike appears to be carb. so that should not be a concern.
The original and replacement harley part has 3 wires because the tip over sensor is part of the sensor...keep that in mind when looking for a replacement sensor.
The tip over sensor shuts motor off if bike falls on its side.
The orientation of pictures makes it a little difficult to decipher but it looks like something is different at outside of exit hole for wire at bottom of cone.
Might require some cut hex bits and small wrench to loosen bracket that might be holding wire on bottom outside of cone due to clearance.
If replacing with a stock part then just scribe "cone" at triangle to the left of wires then match triangle on new replacement factory part to mark you made on "cone".
Factory part is about $190 and you need two blind rivets or a new cover.
General tools should be fine along with some cut allen/hex pieces for bolts due to clearance.
I would not be surprised if a dealer might want a diagnostic fee ,+ 1.5 hours labor + hand washing/service fee of 10% +tax.
An independent might suggest a simple cost effective after market unit with no tip over sensor (loss of safety feature) and save you some money on labor.
It is not a difficult job and no fluids will be leaked.
The most difficult part would be to make sure that sensor wires are properly situated in sensor connector to bike harness connector.
There are only 3 wires.
The sensor comes without deutsch connector installed since you need to feed it through hole on cone first so that is why some folks have hardwired connectors since they do not want to lie on their back to decipher the deutsch connector.
But the triangle 3 wire connector is no big deal to address in factory style if you pay attention and are using a factory unit.
Judging by the rivets in your timing cover I'd say the sensor inside was the original. My original lasted 26 years before it melted. Age and heat will eventually get them all. Nothing to worry about. When I changed out my original sensor I also milled out the back of my cover and added the nuts to act as stand-offs to vent some heat. Works great.

The line-up of parts makes it impossible.
Since the bike had rivets,original CAM sensor and beige goo it reads like a stock unit.
It would seem like your unit is stock but you can also look for marks on bolts for cone in that area.
As suggested back a few posts the CAM sensor plate could have been reached by using some cut allen/hex wrenches to access bolts without removal of exhaust.
Although removing the exhaust does make access more straight forward.
If you decide on changing bearing then might as well start thinking about other stuff like gaskets, lifters, new cam and then make the decision of adjustable push rods or original solid.
It really depends on your pockets, skill set and how much you want to get into the bike.
A Cam sensor and be done or add about $500 USA dollars for parts like rocker gaskets/ lifter block gaskets/cone gaskets, new lifters, new cam, new bearing, seal, adjustable push rods, some misc items and a carb adjustment.

It's a common problem caused by the materials used by the manufacturer of them.
That said getting that stock cam out of there will put a big smile on your face but you will have to tear down the motor if you want to do it right.
