Small coolant leak

I have a very small coolant leak at the front cylinder base gasket.
the cylinder and head itself are clean so i know the coolant is not coming from the pipe above.
There is no mixing coolant in oil or vice versa, it loses only a very small amount each day.
It will be a winter project since i don't think there is any danger to running as is for now.

I know i have to pull the engine to get it apart.
My question is, do i have to remove the cam chain or can i sneak the cylinder off after removing the pin that goes between the chain?
I don't want to have to take apart more than i need to in order to fix it and will probably end up doing both sides to prevent future leaks.

It would appear that no one has ever tried to remove the top end without taking out the cam chains.

It was a small leak so i used black RTV on the corner that was leaking.
Does not make sense to me to remove the engine and tear it apart to fix a minor leak.
It is a clean bike and looks really good for a 1989 but it is no show bike so a little RTV black won't hurt it.

It's all good, i figured most people probably follow the service manual.
If i do tear it down this winter to replace the gaskets i will upload photos with info on how i did it if it is possible.

I have the same issue on my '89! 27,000 miles. So far, I've just been topping off the coolant tank. I talked with a mechanic who wants to charge me $300-$500 to replace the front gasket, so I am VERY interested in how this goes for you. PLEASE post your results.

My stator is still good, but I was going to do the Tuxedo mod while the engine is out. That way, I'll be able to replace the stator later on. I was also going to check the engine dampers while I was there.

'89 VN750 Bought stock 4/12/18 @ 17805.9 miles $800. Wrecked once. 27454.5+ miles

Completed modifications:
Removed mufflers, straight pipes out of GB. 110/90 Front Tire. Pick-up coil mod. Shindengen MOSFET FH020AA r/r. USB Outlet + Voltmeter. Repainted Metallic Blue w/ new tank bages. Ear Shave (wo/ coasters) 40/140 NO shims 45MPG. MCCT conversion.

Planned modifications:
Custom LED turn signals. Windshield. Highway Pegs. (Possible) ignition adv. Tuxedo Mod. Ignition coil mod.
