That's some good thinking, Harley is looking for people like you.

There are two major advantages for Rocker Lockers, yes they lock the shaft, but just as important is they center the rocker arm assembly plate where it was designed to be, every time. Without the inserts there is as much as 1/8 inch play on the bolts, the plate can rotate as it is being installed. This can cause the push rods to scrape on the tubes, or cause the rocker arm foot to be repositioned on the valve stem causing multiple wear patterns on the foot. (We have seen this on many 100k motors.) It puts the push rod at a slight angle changing the geometry of the rocker arm, and can cause the rocker arm to move back and forth if not properly shimmed. In the past we noticed that the majority of this top end tick was after the top end work had been done and contribute it to the placement of the plate creating additional angle on the push rod and lateral movement in the rocker arms. The advice I would give if using this fix is to be aware of the placement of the plate during installation.

Smarter than the average bear! Definitely easier than the rocker lockers and I already have the set screws. Appreciate it. No more sewing machine for me

Very interesting and thanks for the video. I just came across your channel in my feed actually and I'm happy to support your efforts and those of other fellow moto content creators. I look forward to seeing and hearing more from you in the future, keep up the great work and ride safe out there.

Well done lad! Highly appreciative of this video

Good idea, but after riding HD for over 30 years I just look at the engine noises they make and they all do through the years is just HD music. And in this case HD doesn't mean High Definition! But seriously I feel with the design of this engine if you try to tighten things up to much one could be looking for problems. This engine, even though they have made updates is basically the same design from the old Knucklehead just variations. And it needs to run more loose in order to allow for it inherent vibrations and to allow for proper lubrication being air cooled. I believe you tighten up to much to quiet them down and you Open more problems down the road. I love my HD music! But you did have a good idea and put a lot of thought and I will give you a thumbs up for that! Carry on!

I tend to agree with your comment about H-D engine design and the inherent sounds that it makes. Do the proper maintenance and a Harley engine will last a long time. Just like a noisy diesel engine. If you want a quiet motorcycle, buy a Goldwing.

Nice job. You're right about WHEN, not IF you have to go back in. I have pulled out and reused Rocker Lockers with a puller I fashioned on a lathe out of a Gr8 bolt and a sleve. Your method is one and done.

Was thinking about rocker lockers but I'm definitely going this route now!!! Great idea and I'm stealing it lol

That is a very well thought out mechanical stand point, thanks

Great solution for those of us overseas. Rocker Lockers are incredibly expensive after you factor-in their crazy overseas shipping costs and import taxes (which include tax on the cost of shipping as well as the product itself). This, on the other hand, is a $5 fix. As an aside, I seem to spend a lot of time chasing-down this or that rattle on my Harley. Might be time to just call it a day and buy something else.

Excellent idea! Thanks for sharing this video 👍

I like it better than the rocker locker. Thanks for the info.

Very clever...I like it!

Genius, very nice.

The problem with this method is the set screw will upset the metal shaft and prevent the shaft from sliding out easily and will scrap the very fine machined bore. The only way to use this procedure safely is to grind a small flat were the set screw contacts the shaft.

Maybe a video showing us how you did it 🤷🏻‍♂️ this clacking makes me cray cray

Thanks that is another great idea

Way cool idea I'll give it a go

You could also put a 1/8 inch set screw first, then a 3/8 or 1/2 inch on top to insure a double lock so vibration won't loosen the screw.

Great idea!

I'll take you up on that idea 👍

Good one.

Couldn’t you just spin the shaft 180 and grind a new smaller crescent groove, trial and error till it’s a snug fit.

@fogit4668

Now there is an idea. Just make a flat on the shaft that lines up with the set screw hole.

Brilliant

I love the idea. The set screw is obviously hardened steel, and the rocker platform looks to be fairly soft aluminum. Would it be better to add a helicoil insert?

If the set screw needs to be long enough to prevent falling out, it doesn’t sound like there’s a lot of confidence the set screw won’t come loose. If it does vibrate loose, the original purpose is defeated. I like the brass sleeves better.

Outstanding idea thanks!

Seems like a sound idea,if you have the tools to do. I’m one who has so I may give it a try. Thank you!

Smart!

Hello, very clever idea and solution! One concern that comes to mind is IF that set screw does work loose, as it releases from the shaft, the hardened shaft could pivot/vibrate and do battle with the tip of that set screw - shredding off hardened metal particles that could escape into the engine. With the brass rocker lockers, if the shaft has any remaining free play, the slight ticking action could dimple the sleeve and over time release brass particles. So in both cases, it’s hyper-important to achieve zero free play. I suppose the stock design, with shaft ticking against the bolt is not ideal either! It must have been a design decision in favor of loose fit = faster install/assembly at the factory.

Theres no way it would be able to completely fall out the way he did it...

Tim Stone... I have installed rocker lockers on several bikes now and sometimes they work to eliminate the noise and sometimes they don't.. In the cases where it doesn't the noise is probably coming from the rockers moving back and forth on the shaft.. I don't like using shims on them because unless it's likely to wear out from metal on metal friction hardened steel. Definitely don't want metal shavings floating around in the oil. I like your idea with the set screw in the bottom but my only concern is does that end of the shaft need to float as well? If not it seems like Harley would design the shaft to be a press fit into the rocker plate and still allow the rocker to float.. Just my thoughts.

That side of the rocker shaft is held in place by the bolt going through it. Locking it down with a set screw just keeps it from rotating. The other end on the other hand needs to expand with heat. That's why he mentioned doing this mod on the same side as Harley.

Super idea, very clever, just i am asking you, it will be a problem if i will use both methods rocker locker and your idea with screw?To be more safe, what is your opinion.I am asking you this because i done allready last week puting rocker locker and still make noise.

O hell yea that’s a good idear

Why won’t anyone make a bolt that is shouldered larger with the same length, thread, and head as factory?

Thats exactly what I think. Shaft as thick as the rocker locker sleeve until thread portion, just slightly shorter so it doesn't bottom out. It's pretty easy to make a bolt on a lathe. Are they even high tensile?

I have a small one man shop & have installed rocker stoppers on several bike & every one I do I'm thinking what a pain these are gonna be to get out of I ever have take apart ! That is a killer idea which I'm gonna start using right away ! Any thought s on an Evo motor my every day ride a 91 FXR is doing that ticking as soon as it gets warmed up ! Was looking at some Evo rocker boxes it could be done but no safety like the twin cam the set screw could fall out ! Maybe use red loctite !?

@tracyjones6284

If you use red loctite,you will have to apply a lot of heat to that screw before you can get it out. Blue thread locker will work just fine.

Did you have to drill and tap for the set screw? Or is that a pre-existing tapped hole?

That’s what I was wondering, did you ever get any clarification?

Would a screw that is 3/8 inch long work?

Your method sounds great but, my thoughts are… when/while the engine is running it’s gonna turn and twist the rocker shaft,… causing the set screw to run against the shaft causing metal shavings., the brass inserts are mailable allowing wear not like steel on steel,… idk I like your design but I like the brass inserts… let me know how it holds up and runs

Ok, how about a hard plastic sleeve?

Just watched this again. So I have an idea. Drill your hole for the rocker arm shaft set screw with the shaft in place. Let the drill bit hit the shaft. It will leave a mark. Then pull out the shaft and grind a flat where the drill bit hit. That should stop all possible movement of the shaft. What do you think?

Engine sounds pretty good (but still room for improvement). The pivoting shafts is only one of the sources of noise from the rockers IMO. Removing excessive end play (shimming) and worn bushings are also noise contributors IMO.

I’m trying to do end play on 1997 Harley sportster 1200 amdseems none load side is same on both witch is the valve side because that’s the side the feeler Guage slides down next to it. Aka it’s not a twin can it has 4 cams. Also is the spec still .003 min cold on my bike ??and does that seem correct that none load side is both same as in valve side.?

If this is such a common problem WHY hasn’t Harley tightened these rockers over the years???? If it was an issue I believe they would of corrected it on later models.

Are you in wisconsin and want to do mine? Lmao, the tick on my bike is obnoxious.

tHE SHAFTS IN MY 2003 WITH 109,000 MILES are not loose in the rockers. (more like a press fit) If your shaft slides back and forth you most likely have a bad fit.

Just my 2 cents,. If Harley engineers would really do any work,. They could make the other end of the shafts square... But that would be too easy right ?? Giving extra work to Chinese parts makers must be their thing !

@randywhitford288

That would solve the "issue" of ticking but cost more money to do. This ticking is annoying, not an actual issue that is causing harm. Then you would also have the problem of locking the shaft in place unless you keep the bolt going through the same hole and notching the shaft anyway.

Don't forget the lateral play that will require shimming the non load side of the rocker arm. If your using rocker lockers...you're gonna be shimming.

Ok, this locks the shaft... but your tapping that plate and making more mods than what the rocker lockers require which both locks that shaft and narrows the bolt hole, just seems like overthinking IMO.

You don't have to have those lockers press can they drop right in with your finger and you can take them right back out with your finger by just turning over the plate you're telling people that they have to be pressed in and that's not true at all they just drop right in place

Problem is you'll wear out your rocker shaft pedestals as they get no lube. Then your rocker will walk all over your valve stem, eventually getting so bad that the rocker will chew up the valve.
