Luckily with enough $$$ anything's possible!

It's been a loooong while since I've dealt with this, but if I recall correctly, you've got 3 choices...from $ to $$$. Naturally, the amount of work required is similar.

1) Strip the chain-enclosing covers, etc., and run a standard o-ring chain.

2) Convert to 14mm belt using parts from shovel FLTP(?) they made police shovels from maybe 1980-1984 with factory belts. Not terribly strong(strong enough for a stock shovel), but cheap if the right donor parts can be found.

3) Full 1 1/8 or larger belt conversion. This will require major parts and coin investments.

Again, it's been quite a while for me on this topic. I definitely recommend looking up BDL and Rivera/Primo. They both make excellent products, and I'm sure they can be extremely specific as to precisely what mods are necessary for what options, and pricing.

I asked him if it was a PITA to deal with? He replied that getting it sealed was difficult. But its been fine ever since the job got done. He used that silicone based sealer/gasket stuff (rtv?)

Why give up something that works so well? Its the only part of his bike that I am a little envious of.

nobody rides half as well as they know how.

Like it was said before, with enough $$$ you can do anything. However, I don't understand the reason for doing this...especailly with a 1984 anything.  An "O" ring chain? Yep...I've used them...and you STILL have to oil the thing and keep it adjusted.   I've also had (plastic) chain enclosures on a few Honda 750's I've had...they surely work to keep the chain clean(er) and oiling intervals are further apart....that, by itself is a good thing.

Personal opinion: keep the chain, oil it, adjust it and enjoy the bike.

The late stock belts are more than strong enough. Most belt-to-chain swaps are due to superstition and unfamiliarity. The only b-to-c swaps that are necessary are because it's behind a monster motor(110ci+), or for additional wide tire clearance.

The belt I mentioned (and questioned it's strength), was the early 14mm(9/16") belt. The later ones like yours are 1 1/8"-1 1/2", and much stronger.

ibafran: I agree...if you can get them sealed, they work very well. But...I do not tolerate leaks. The hardest part of that equation is parts availability for broken/warped covers, followed by continual replacement of the seals at the trans and wheel. If it's just a matter of leaking boot/cover o-rings/gaskets, I definitely recommend a thin wipe of Permatex Black on clean/dry gaskets/o-rings-not as their replacement.

If it don't leak, it ain't a Harley.  I drilled a hole in the primary case of my '02 Nighttrain soes I could relive my Shovelhead days.  Ride Proud!
