Gotta? about a new noise possibly coming out of the primary of my 21 bob 114, the noise is kinda the same sound as we get from the fuel pump after the bike is shut off. But was only doing it while decelerating around 20 mph while coming to a stop, but then it stays consistent if i hold the throttle steady around 20 mph. Come to a complete stop there's no noise, pull back out there's no noise. The bike is closing in on its 1k service with a tad over 800 miles on the clock, and is still stock other than a set of header pipes from a heritage, along with cutting the baffles out in order to install some TTI's. I do tend to goose it up through the gears, which makes me wander if the adjustable tensioner relatched up making the chain have less slack. Just looking for some perspective so i don't sound like an idiot trying to explain my problem to the tech guy lol.

 

Wow. I don't even know where to start here so I'll just do my best to be short and nice about it.

With less than 1.000 miles pre first servicing on what is now a 2 year old bike I think any tech is going to look at you sideways for such a complaint.

My '22 Heritage made a plethora of different noises as it went through it's break-in miles and that was with me following all the break-in guidelines of keeping the revs low untoil the appropriate amount of miles were on the bike.

I could swear I actually heard the rings lapping themselves into the cylinder walls and the bike's engine and drivetrain seemed like it was all discombobulated until it got enough miles to get a grip on itself as things settled in and settled down and I might imagine a brand new clutch pack seating the fiction plates with the steels is not exempt. (which is what I suspect you're hearing changed especially if this 2 year old model year bike sat for any length of time with the original equipment dino oil in the primary)

At 5K miles I thought my 114 was finally broke-in especially after I did my own 5K mile servicing switching up to Mobil 1 V-Twin for engine oil but I was wrong because I did my 10K servicing at 8,900 miles where I included both the primary & tranny using Mobil1 in the primary as well and HD's 80-140 synth gear oil in the tranny and once again things quieted down and slicked up but the eye opener was when I installed Khrome Werks slip-ons along with a V&H FP4 reflashing the ECM with a canned map where it takes running 2-3 tanks through the bike for the ECM to iron itself back out again which I just got to experience for the 2nd time which it did and now my bike is sounding like a fully broken-in Harley with a quiet, slicked up tranny.

At 800 miles I might imagine you have maybe 5 tanks through your brand new 114 and your engines journey through break-in noises has just begun. You'll know I'm speaking the truth as you begin cycling through servicings.

 

Sure your not hearing noise from the exhaust? What gear and rpm at 20 mph? Harley motors fire opposite cylinders but are not exactly 180 since they share same crank pin.

That makes them a little uneven in idle and engine break. The compensator hides most but translates it back in uneven noise.

What kind of noise do you think you hear from the fuel pump when bike is switched to off?


If the primary sounds good at idle in neutral, it's probably OK.

The tensioner is not going to ****** too tight unless the chain is extremely worn in uneven sections. Then it's possible it could set there and then be tight other places.

You would hear it then at idle. And odd out of sink slight grind.

Get you a two ear harbor freight stethoscope. With your exhaust, no telling where noise is coming from especially with an all aluminum compact motor and drivetrain. Noises travel all thru it.

Lot of noise is normal with those steel roller bearing. With a stethoscope, they make a smooth noise and not a rumble.

 

If you're talking about that high pitch whirring sound that comes from the primary as you slow down to a stop... Yes that's normal.
What we need is a video or recording of the sound so we can get a good idea of what the sound actually is.

 

Yeah man, its around 20 mph or so in 3rd gear, which kinda sounds like a brake dragging, but im making plans on turning my 1k into an 800 mile service. I did change the header pipe that i purchased from ebay off a heritage, which drop the slips a bit to make more room for bags. I managed to get the miles up to 500 last year before i pinched a nerve in my shoulder to which the bike sat up until winter then sat some more. Now that good weather is upon us here in SW PA, im out and about, but have read if you get on it pretty hard, the chain tensioner can click up a notch making the chain to tight. But be that as it may, its going in to get looked at.

 

The M8 Softails have 2 counterbalancers. Some are quiet, some sound like a bearing is about to seize. I got rid of a 21 Heritage because of it. And, I don't think I'd give much merit to what you heard/read about the tensioner. I pulled the primary cover off my 21 to inspect that as well, and in my case it was not an issue.

Does yours sound like this?

 

Not really, that's more of a chirping noise, the only thing i hear on mine at idle is the whining from the balancer's which i think is cool actually. But imma gonna run it around this week to see if i can get a better idea on what im actually hearing, i mostly only hear it when im slowing down. Also gonna pop off the derby cover to rule that out, also gonna do my best to post a video, definitely not one of my strong points lol.

 

You should be completely fine.
I just recently took my primary cover off to inspect my chain tensioner and it was only up four clicks from zero and my motors stage two and I get on it and smoked tires…

 

There is the chance that the "Oil Spinner" has come off. Mine did on my 18 Fatboy.

The Oil Spinner is #15 in the picture. It's made out of some type of composite material.

 

Oil Spinner is only on the WideTire Softails, Fat Boy Breakout and FXDR.
It's not used on any other softails.
