So I switched to a solid comp and Hayden tensioner all was well for 600 miles minus a whiring sound that I assumed was from Hayden tensioner after some research, then I developed some serious knock/chain slap noise, took primary cover off and found chain slap marks on top of primary cover. So I did some more research on Hayden tensioner and got paranoid and put my stock one back in, didn’t solve any noise issues I think it stopped the chain slap that’s it. Idk this is my first hd and I don’t really have any help and funds are limited of course. I’m trying to put a cart together to order the parts to get this thing back together. What I need to know it what should I replace, I really need to keep it less than 600$, I think I need a inner primary bearing, primary chain, not sure of what else I need that could be causing noise other than clutch hub bearing that’s the one I’m hesitant on as it’s 90$. 2016 dyna low rider 10,000 miles, stock 103 with magnaflow 2 into 1, destroyed comp at 9400 mile. Any help would be greatly appreciated.

So YOU installed the Hayden and related parts and hardware ? Are you a trained Harley mechanic or any other trained professional mechanic by trade ? Do you have the MoCo service manuals and special MoCo tools on hand ?
So ... you joined this forum 42 minutes ago and logged in 12 lines of a single paragraph blaming the parts that YOU installed ! Say what ? I'm interested to read more from you to get a better understanding of what you've been trying to accomplish ! Really !

Am I certified? Bud I tore this thing apart in a church parking lot beside my apartment complex in Philly. I have the service manuals downloaded. I have access to tools needed for inner primary. Other than that I own everything. I’m just a new Harley owner in my 20s trying to get this thing fixed without taking a loan out. Maybe I’m not welcome here?

That's good dude, HaHaHa ! 'Tore the sucker down in the church parking lot ya did' ! OK so now I have a good idea of where you're at, and YES you are welcomed here I'm sure ! You might get picked on at first but if you hang in here and have thick skin you'll be good.

Solid engine sprocket are noisy, having one myself. Does the clutch hub move alot on shaft? Primary bearing fix switch to 07 bearing as it's self contained and eliminates the inner race on shaft. I swear that the twin cam is the noisiest engine HD made.

Well, someone has discovered that motorcycles aren't as simple and easy to work on as one might think.

They're as complicated (or can be) as any car if you're not naturally mechanically inclined or generally experienced mechanically. So many people think it'll be as easy as working on a bicycle until they tinker, screw stuff up or get into the middle of a job and suddenly what they thought would be like working on a bicycle is more like working on a rocket engine. If you wouldn't try working on your own car, you shouldn't try working on your motorcycle.

Not saying that's necessarily the case here, but it happens all the time.

Please Schmidty, Fritz or Kyle; correct me if i am off track here!

Take on a challenge, make some advancements, make some mistakes... How the hell else does one learn?
I am NOT busting on you! Just read through this to see my point. A couple of things to think through while learning and exploring with your bike:

In reading through this thread, it seems to me that when you installed the (then new) Hayden chain tensioner is when this chain slap issue begun. That pirate (downloaded manual) may have lead you astray or, you may have overlooked a very important step in the process of adjusting the tensioner:

Did you:
Remove the spark plugs and elevate the rear wheel, then put the transmission in its highest gear?
This is so you can rotate the engine ONLY in the normal direction of travel (via the rear wheel).

The first step after the primary cover is removed is to visually inspect the teeth of both of the sprockets. If they appear to be cupped from chain wear. They need to be replaced. (All the adjustment in the world will not correct for a worn sprocket.) Which leads to this question: How did the teeth of the old compensator sprocket compare with the new solid comp? Did you inspect the clutch sprocket for abnormal wear?

Did you try pushing and pulling on the clutch basket to feel for endplay? What about the front sprocket end play?

Then when adjusting the tension of the chain: Did you keep forward rotation load on the rear wheel? How many different points along the chain did you check the tension? (It takes a few, usually 3 or 4 times around for me.) It is a healthy workout at times.

This takes us back to that downloaded manual (Forum members HATE those pirated copies for a reason!) In all honesty, I have one of those downloaded on my phone, just as an emergency measure. If things go wrong on the road, it should be enough info to get me home. Where i can take the time to verify on the MoCo hard copy...

The HD Service manuals run about $140-150. The single best upgrade you can buy for your bike!

Does your version of the manual say to adjust the chain at the tight spot or, the loose spot? See where this is going?

Please keep this thread going and stay with the forum!

The members here honestly enjoy helping out!

It's safe to say: There's more years of combined Harley knowledge here than there are years of Harleys..

We have an enormous amount of "One, n, done" new members as of late. Some of the "real experts" getting gun shy (so to speak). A thick skin is not s requirement here but, it sure as hell helps! Roll with it! (y) You'll be glad you did!

To the OP's question, we don't know what noise he is hearing and he's asking what parts to throw at it.

The answer is never to throw parts, the answer is always proper diagnosis first so you get the right parts and know what the problem is to know how to fix it. We honestly have no clue even what's wrong, just there's "a noise", we don't even have a description of the kind of noise.

What I got was he swapped to an automatic tensioner and a solid comp sprocket. So basically, does not have a compensator. We don't know if he changed to the right sprocket for the job (there's different offsets for different things, there's differing numbers of teeth which could change the primary ratio resulting in the need for a different pitch of chain). We don't know if he even got the correct Hayden auto tensioner for his application (there's different models and different ways of setting up the different models for different applications and needs).

Then he is swapped back to the stock tensioner and the chain slap is gone. Assuming having the same compensator eliminator sprocket.

Granted, I was a bit snarkier than usual and offered no help, but that's the questions to ask. Still using the comp eliminator sprocket and what exact one is it? How exactly does this noise sound? When swapped back to the stock tensioner, is the chain tension set properly?

We need to verify exactly what is in and that it's the right parts and installed correctly before we can even begin to move forward with help. Well, before someone else can, I don't know anything specific about TCs.

In Re-Reading the first post, I got this of it:

So I switched to a solid comp and Hayden tensioner all was well for 600 miles minus a whiring sound that I assumed was from Hayden tensioner after some research, then I developed some serious knock/chain slap noise, took primary cover off and found chain slap marks on top of primary cover. So I did some more research on Hayden tensioner and got paranoid and put my stock one back in, didn’t solve any noise issues I think it stopped the chain slap that’s it. Idk this is my first hd and I don’t really have any help and funds are limited of course. I’m trying to put a cart together to order the parts to get this thing back together. What I need to know it what should I replace, I really need to keep it less than 600$, I think I need a inner primary bearing, primary chain, not sure of what else I need that could be causing noise other than clutch hub bearing that’s the one I’m hesitant on as it’s 90$. 2016 dyna low rider 10,000 miles, stock 103 with magnaflow 2 into 1, destroyed comp at 9400 mile. Any help would be greatly appreciated.

"switched to a solid comp and Hayden tensioner all was well for 600 miles minus a whiring sound

then I developed some serious knock/chain slap noise, took primary cover off and found chain slap marks on top of primary cover.

So everything worked well for the first 600 miles after the conversion. Then chain slap begun. So to remedy this, he reinstalled the OEM tensioner.

So, if it was working properly allbee it with a different sound. Why then change the parts back to the original vs simply adjusting the tensioner (that now has 600 miles on it) again? In order to remedy the chain slap. We don't know how hard the bike has been ridden in those 600 miles. Drag racing or riding equivalently? Or the lack of a compensator placing more stress on the chain? Or a combination?

Throwing parts at a problem or, a perceived problem. Is seldom if ever the correct fix. As you stated Kyle, the first step is to understand why.. Not what!

I have yet to meet or even hear of anyone who graduated, this school in which we are all students of.
Could it be that to Graduate from the School of Hard Knocks; the Certificate is the same one the Coroner tags our big toe? Dunno, I'm still in this school...

just for INFORMATION's sake = why ?

Was there something wrong / defective with your original Twin-Cam COMPENSATOR SPROCKET ?

Was your OEM Chain-Tensioner worn out ?

I have installed a HAYDEN (spring-loaded) Chain Tensioner - in my own bike -
but found it to be a "more" COMPLICATED solution for something that was NOT really, in my case, a PROBLEM in the 1st place

Since you RE-INSTALLED your OEM Chain tensioner - I think THAT question is answered
...
but the SOLID COMPENSATOR Sprocket is still a question in my mind ... can you explain "what" it was to accomplish ?

(I'm not attempting to be a smart-ass --- but I am --- just trying to gain some insight into your PROBLEM / SOLUTION before swapping PARTS
