Has anyone had any issues with the oil pump chain, loose, rubbing, etc. If so, did you go into the motor and repair it, or just live with the sound.

You will be biting off a huge chunk of work for a very little benefit that you really don't know will be there at the end.

Many Valkyrie owners over the years have commented about the exact same supposed problem and I recall there was only one owner that reported that he actually found it was the chain that was making the noise.

All the others found different results but the sound never went away with a new chain.

Honda in there wisdom never destined for that chain to have to be replaced, and they were accurate in their estimate I assure you.

Try changing to a different oil and you may find that takes care of the majority of the noise.

Pulling the engine and going inside it is not a problem or issue. All I'm looking for if there are any special tools required for the job... The chain is the problem, either slack in tension or it's rubbing on the guard. Would like to talk to someone if that's done the job before.

You might pm Grumpy. He is the only one I remember doing it.

which oil pump are you referring? only one has a chain, and I have never read of anyone having a problem on valkyrie or GL1500 Goldwing forums.
the one with a chain is behind the clutch basket. your noise could easily be normal clutch noise.

This reminds me of a post years ago.
Does it make the noise all of the time or just when the clutch lever is pulled in.

I know what the problem is, that's not the issue. What I'm looking for is what if any special tools are required to access the oil pump chain, after I pull the motor.

The shop manual usually references any special tools if they are needed.

OK you've got my attention. How do you know it's the oil pump (scavenge) drive chain without splitting the motor ?
Over the years I've rebuilt several GL1500 motors (Valk and Wing) and never seen a worn chain or excessive slack. Even on my supercharged Valk where the motor had to be replaced with a Wing bottom end (enthusiastic use) the chain and it's guide were fine. BTW you obviously know the motor has to be removed from the frame and the rear crankcase, primary drive and clutch removed.
Service tools - to remove the primary gears and output shaft, mainshaft holder 07JMB-MN50200, Lok nut wrench 07916-MB00001.
To remove the clutch - Outer basket holder 07JMB-MN50100 (made my own), clutch centre holder and its pins 07VMB-MZ00100 and 07HGB-00101B (made my own).
Bought or made these tools years ago so no idea whether they are still available.
As I see it the chain is a multi row  Hi-Vo type and way under stressed for its purpose. 
I'd humbly suggest you look for other causes before diving in.

Over half a century of trouble shooting and rebuilding engines, both reciprocating and gas turbine. No question the sound is chain related, and there is only one chain in the whole bike. Spoke with Grumpy, he had the same problem. Bolts backed out of chain guard allowing chain to rub on it. Very rare problem but that's my luck. Thanks for the special tool numbers, that's what I was looking for.

I had this issue on a Yamaha XJ650.   I was able to shim the oil pump without pulling the engine. The Valkyrie looks  much different according to the book. I don’t think it would be that easy.

Yea, wish it were that easy Chris. Got to pull the motor, rear case, and primary gear just to access it. God love the engineers at Honda … cause I don't think anyone else does.

Love the Honda engineers or not, I would rather have one well designed and a little difficult work on once in while, than one easy to work on continually.
