Changing to a Chain - How tough?
Times have changed and it aint that bad now.Put it on the lift and spin it freely when lubing it up,let it set for a few and wipe off the excess.It lubes the plates and O -rings and dosent sling it all over when you ride.I have a belt on the 06 and a chain on the 84.Both are trouble free.
Your gonna need to get the bike up on a stand so you can start pulling things off the left side: outer/inner primary, then the transmission drive pulley. If you've never been into the primarys, you'll need a 'tool' to hold the two sprockets while you remove the nuts. And they are on damn tight...Along with thedrive pulley. An impact is almost a necessity, and having a couple torque wrenches is definitely a requirement. I'm assuming you alsoinstalled a heavy duty clutch pack with the Big Motor? If not, it's best to do that right now. The stock clutch is gonna go bye-bye with that much hp/tq and a 'need to use it' wrist. You'llobviously have to replace the gasketswhen you reassemble.
Naturally, you'll also need to pull the rear wheel/tire. And remove the rear belt pulley, which may or may not be easy...Depending onhow the machine screws come out. I'm not certain about the Dyna's, but I know changing a belt on my Electraglide is a royal pain, cause ya gotta take the swingarm out. But since you're converting to chain, you can just cut the belt, if necessary. You'll also need some sort of means to measure the rear axle when you re-assemble so it isn't cocked. The FSM probably has a diagram of a tool you can make out of some welding rod and a rubber grommet.
The whole 'project' shouldn't more than a Saturday for the 'average' guy working in his garage. If he's got the tools. I know from two prior experiences that the dealer's charge 4 hours labor to replace/tighten the transmission drive pulley (which is basically what you're doing). So I'd add another couple hours for the rear wheel, and beer breaks.
It's unfortunate that you didn't make the belt to chain decision at the time you put the motor/trans in the bike. Personally, I'd check the adjustment on the existing belt, run ituntil I shred it. Then go through the conversion.

It sounds to me like your belt is not adjusted and your pulleys are worn out.Several of my friends having been running belts and NO problems ever.One friend has a 155" Bourget with 35,000+ miles no problems.Zippers has a belt to chain conversion kit,and without certain tools it can be a pain to convert it over.

No big deal as all parts still available on Ebay, I managed to by NOS oem parts for mine
A good service manual is the way to go to remove and re install the primary. Not a big deal really.
You WILL need a special tool to remove/install the trans belt pulley nut.
I would look at upping the clutch like to better spring and new plates at least.
I run an open Primo.
I also have a Carlini torque arm to tie the right side engine to the trans. But in all reality that huge motor plate on the Primo doesnt allow much flex.
As for reliability or maintenance....
I have hundreds of runs and tons of road miles. Only adjusted the chain maybe twice and no oil on the wheel because of the sealed "O" ring chain. Use light oil on it applied with a rag every so often.
You'll never wear out a front chanring they are big time steel, I run an aluminum rear and it looks new.
