Been doing this mod for over 20years. Told everyone I know, but they all thought they knew better, & spent ungodly amounts of money. This mod completely eliminated the nose dive that occurs on the stock suspension on a Roadglide.
Yes, simple, less expensive, and works great! Glad you are seeing the benefits of having them installed. Thank you for commenting! MB
I appreciate knowing the mechanics of why it gives you a better ride instead of just saying "it's better, trust me." Looking to upgrade my suspension in the near future. Will definitely be hitting up DK Custom for these parts! Keep up the good work.
Thank you for the kind words. We appreciate them and your business. Always feel free to call or email with any questions.
I haven’t even watched the entire video and I applaud you for selling this type of suspension modification!
I run RaceTech Gold Emulators on my CBR and they are designed very similar to how those are.
I will watch the rest of the video and will likely be ordering these for my RK as she’s in need of some suspension mods!
Thanks for sharing, I had no idea that these existed for our big heavy touring bikes.
Good to hear you that liked the video.
Thank you for the kind words, and we appreciate your business.
If you like the Gold Valve Emulators on your CBR, I believe you will like these even better.
@@DKCustomProducts why would you like these better then the racetech gold valves. Just wondering what the differences are
@@arthurcutaiar9994 copy and pasted from the report linked above-
With the Gold Valve Emulators there are quite a few extra steps in the installation process, including complete disassembly of the forks, drilling holes in the Damper Rods, and reassembly. Because the Intiminators produce just as good a result, and are much easier to install, we prefer them.
I think I get the reason for it - braking is a more gradual compression, hitting bumps is a quick compression so it's better to have the front shocks behave differently to each type of hit.
That is correct.
Chassis input (front brakes, rider passenger weight, gradual dips, accelerating in a curve) all should result in minimal fork compression.
Wheel input (bumps, cracks, expansion joints) all should result in a quick compression and rebound of the front forks.
That is what these do, resulting in very predictable handling, keeping the bike stable, letting the forks do the work of keeping the tire in good contact with the ground, while keeping the bike level.
Different valving for different events the front tire encounters.
I sure wish these had been available about 6 1/2 years ago before I bought the Legends Axeo for my 15 RGS. I'm not complaining about the improvement of my ride quality with the Legends but this appears to be even better. Next time, this will probably be my choice. Great video!
Yeah, they are surprisingly effective. About 6 months ago I did back to back tests with the intiminators and then the new Legend Axeo. I was very surprised at how poorly the Axeo's worked, relatively speaking. They are much better than stock, but I did not like them as well as the Intiminators....AND I wanted them to be good. We were making a video to promote the Axeo's and we were planning on putting them on our website. But that did not end up happening after our testing.
Data will be in our updated Front Suspension report in the next month.

The last few minutes brought it all together.Thank you.
My 2005 Specialized S-Works Epic MTB used a similar concept for their front and rear shocks- used inertia valve technology on their Fox shocks (Terra-logic). There was a rebound and bump sensitivity adjustment-they coined it the brain shock. They also had the same brain concept for the rear shocks. Still riding the bike after many thousands of km’s,-Cape Epic etc etc
Like to install the Intimidator on my 2008 FLSTC.
We use the IAS in our Shocks and Intiminators. You can see the Intiminators at this link - www.dkcustomproducts.com/improved-front-suspension-w-intiminator-fork-valves-for-harley-dk-ric-int-39.htm

I’m anxious for you to combine this with a spring kit or even a cartridge. Looking forward to that.
Spring kits can be seen here- www.dkcustomproducts.com/front-suspension-c652.htm
I don't know if it will ever be combined with a cartridge, but it can currently be had build into the 14" shocks for Trikes, which can be seen here- www.dkcustomproducts.com/dk-custom-nexgentm-14-trike-series-shockstm-for-harley-davidson-trikes.htm
The beard looks so cool! Said nobody ever!
Kevin's wife life likes it, he likes not having to shave, so it's a win-win for him. 😎 MB
Makes perfect sense, you want the wheel to keep the contact , wish they had made this video a year ago.
Yes, very important to maintain the contact patch. Glad you like the video, sorry we did not do it years ago.
I found it fun to watch John try to explain the differences of damping; it's a complex concept for those unfamiliar with the dynamics of suspension.
Chassis compression won't open the inertia valve because it is much slower in application, forcing oil through only the shim stack. Wheel compression rapidly forces the main spring into compression, opening the inertia valve to allow fast oil flow through the valve until the inertia valve spring catches up with and overcomes the damper rod speed thereby closing the valve and forcing oil through the shim stack. Rebound damping is provided by the check valve but is non-adjustable.
I was wondering how you got around the damper rod orifice size running with the OEM spec oil weight. Lessening the oils viscosity does the trick by speeding the flow through the damper rod thereby making the Intiminator valves do the damping action. (Similar to GVE's but without the need to drill the rod orifices out).
A very interesting concept.
EDIT: The damper rod orifices are still the limiting feature due to oil flow limitations. If you're using OEM spec oil weight as per the instructions, how is the oil flow rate through the damper tube overcome?
Great, concise explanation. You may have said it better than we did!!! Thank you. 👍
When using the Intiminators a lighter weight oil is used to pretty much take the damper rod orifices out of the damping equation.

Different Intiminators use different weight fluid. (5W for 39mm and 41mm forks & 10W for 49mm forks)
Y'all kinda just answered my question about the dampener rod orifices
yes he did!@@DKCustomProducts
installed the intiminators today!
Took the forks apart and installed the Intiminators today. Relatively easy job, but did take a buddy and I to put the fork cap back on considering we did it manually with out a press. Once we had the first one figured the second one only took 15 minutes or so which included a beer while the fork drained upside down.
Prior to the change I rode a route that included city driving, pavement cracks, bad asphalt, and a cloverleaf. I crossed a set of train tracks twice. I also braked fairly aggressively from 50 kmh to try and quantify the brake dive. After the change, I essentially rode the same path.
From my seat of the ass study, I believe the bike dives less quickly than prior when braking. It also strikes me that braking with some dive and hitting an expansion joint is less “abrupt” after the change. The bounce over the tracks is hard to say since the whole bike moves anyway. During some of the shallower bumps on the city streets, it feels like the bike is more planted. Perhaps the rebound is more controlled. It also seemed that the bike tracked better during the relatively aggressive cloverleaf turns.
All in all, I believe there is a difference; however, it doesn’t strike me as a nite and day difference like I had when I changed my ’89 and ’07 E-Glides from stock to progressive front springs and 412 rear shocks. Nor as significant as going from the ’07 to the ’19. But I believe there is a difference. As I said, it does feel more planted on the ground. I have a trip coming up and will have more seat time with it. Is it worth it? i am not exactly sure what i expected, but yes i think it is. the bike seems to hug the road better. i am not regretting the purchase at all
Now a word about DK Customs. these are good folks to deal with. i first started down the path for this item due to this You Tube video. i had some questions that i sent by email directly to them. Dwayne got back to me with in 24 hours both times. the tag line on their email signature is " To give real service you must add something which cannot be bought or measured with money, and that is sincerity and integrity." It looks like they live by this. really good folks to deal with
Thank you for the review. 👍
Glad to hear it is more controlled and planted, tracking better in the curves.
What year and model bike did you install these on?
@@DKCustomProducts 2019 E glide stnadard
I’ve watched this several times and learn something every time.Thinner oil and the damper rod doesn’t serve much of a purpose and you rely on the intimidator to do the work along with the upgraded spring?
That is correct. The Intiminator is made to work properly with thinner fluid. The damper rod is taken out of the equation (mostly) by use of the thinner fluid. 👍😎👍 KP
So Wilburs makes a front end kit that basically just replaces the stock springs and oil for theirs. I wonder if pairing these intiminators with those would produce the ULTIMATE front suspension for HD touring bikes.
Y’all should make a video testing out these intiminators alone on stock HD springs. And then test out the intiminators combined with Wilburs springs… 😧😧😧
We may do that.
Springs are not even half of the suspension equation. The valving, regardless of the springs, make up more than 50% of the ride quality.
The Intininators will improve the ride quality with any springs.
I'm liking what I see here, I could see where it would be good for both 2 wheel and 3 wheelers. Can they be adjuster by the owner, like say you spent too long at a pig roast and packed on a couple pounds? It appears that you build them according to bike and rider weight, so just curious a situation like that, or say you sell the bike to a much smaller person, would they need to be adjusted?
The Intiminator dynamically adjust damping, resulting in improved riding comfort & control.
This is achieved via a motion sensing valve in the shock body that dynamically adjusts the damping to be ideal for both dips and bumps.

@@DKCustomProducts You can use my bike....I want a 606 installed at the same time.....and anything else you suggest....2020 Heritage Special
Since installing Progressive Springs and these Intiminator fork valves in both of my M8 touring bikes (bought from DK), I have forgotten just how bad the front fork suspension really was.. much less seemly bottomless dive on braking, and better bump control.. I'm really surprised my Large ticket Harley's had such poor suspension.. quite sad
The Intiminators and new Springs do make huge difference. Glad you are seeing the benefits of installing them!
Thank you for your business and for commenting! 👍
OK guys this definitely needs a better presentation to drive the point home. We need chalkboard and illustrations of how shock works etc, etc… you get an e for effort though… so if I am understanding correctly if I use the system that you’re talking about here basically one shock is used for chassis input and the other for wheel input??….
Each fork operated dynamically, adjusting valving for wheel and chassis input. The intiminators that goes in each fork tube are identical.
Very informative video. I have the DK Progressive rear suspension package installed in my 2020 Tri Glide, and would like to improve the front suspension performance as well. Would Kevin be willing to share exactly what set-up he has installed in the front of his Tri Glide?
After watching many of Kevin's videos I believe whatever he chose for his Tri Glide, would be the right set-up for my Trike as well.
Thank you. Glad you found the video useful/interesting.
Very happy to hear you are running the Trike Series Shock™ package.
On my 2019 I am running the stock springs and the Intiminators and am very pleased with the performance.
On my 2014 TG I ran the AK-20's. The best there is. See Front Suspension Report linked below.
I've also run the FST's and they are very good also. While the FST and AK-20 are better than the Intiminators, for the $ spent, the most improvement per $ is from the Intiminators. If I was racing I would use one of those, but for my cross country touring, and daily transpo, the Intiminators are what I chose.

@@philipwenzel4982 You're welcome, the Intiminators should have you all set! 👍 Thanks for watching, ride safe!
great video and good information, but i think i am missing something. from what i can find, my 2019 EGlide standard has the Showa 49mm Dual Bending Valve. the bit of information i can find on this indicates that this is Showa's version of an intiminator, and utilizes a 2 circuit system. in that case, it would be doing what the Intiminator does would it not? therefore the only benefit of the Intiminator would be that i can tailor it to my riding style, weight etc as opposed to the showa which is likely a basic average for everyone kind of setting. thanks guys
Thanks for the comment. Great question!
With the dual bending valves it is a design that uses shim stacks.
This is what is talked about in the beginning of this video. There is a compromise in the dual bending between wheel input and chassis input. There is a shim stack that handles both.
With the Intiminators you have the shim stack which is set more firmly for chassis input, which is why with the dual bending you still get brake dive, but with the intiminators brake dive is much, much less.
In addition to the shim stack for chassis input and small bumps, the intiminators have an inertial valve for harder bumps.
The inertia valves does NOT utilize the shim stack at all, it allows the fluid to flow rapidly, so that on a hard bump you still have a plush ride.
A shim stack only technology will either be plush and mushy all the time or firm & bumpy all the time...or somewhere in-between (compromise).
Intiminators have a shim stack AND an intertia valve, so the suspension is firm/planted when there are no hard bumps and plush when a harder bump is encountered.
I was looking at getting Legends front suspension, hmm? Might look into these first.
We were excited to test the Legend Axeo's a few months back. When we did, we were surprisingly disappointed. No doubt they were better than stock, but they did not come close to measuring up to what we thought they would be after listening to many folks reviews of them.
I believe you will be well pleased with the intiminators. 👍
This is a very informative video. I'm going to buy the intiminators for my 39mm forks.
They work very well, I believe you will be well pleased with them. 👍
Can you do a video of actual install of these on a modern 2017 & up touring?
Yes, we are planning on doing that this fall. It is the same as in the video linked below, the only difference is removing the switch panel below the inner faring to get at the pinch bolts to remove the fork tubes from the triple trees, and doing the installation with the forks removed from the bike.

Thank you for commenting! MB
Pretty slick! Makes sense!
Thank you, glad you liked. 👍
I think I understand how it works, but the explanation got confusing.
The valve basically adds a dampening circuit (the shim stack) for compression travel that slows/ stiffens the ride for the better performance but the one way/ check valve opens and lets more oil through on compression for large bumps to be soaked up. And the Lighter/ quicker oil allows a faster rebound through the factory dampening circuit. At least that’s how I understand it working. Correct me if I’m wrong. Either way I’ll be putting a set on my bike, as the Bitubo rear shocks have highlighted how bad the front suspension is. And has even caused a very strange pogo type ride from the front end on a special section of road when I’m accelerating and going “fast” the road cracks Cause it.
The shim stack is what is functioning during chassis input (front brakes, dips, curves), and as you say it keeps the bike from using too much of the available travel.
Then when there is wheel input (big bump) the inertia valve fires and allow for much more travel, resulting in the bumps being absorbed by the suspension, rather than being passed thru to the rider or passenger.
The check valve (which sits right below the shim stack) allows for the fast rebound, restoring the suspension to a point where there is a lot of travel available for the next wheel input event (bump).
I believe you will be well pleased with the improvement these give your bike.
Good content. Been wanting to do trackerdie extended damper rods, some stiffer springs and the ricors on my sporty to match the taller shocks I put on.
Thank you. Glad you liked the video. I believe you will be well pleased with the improvement from the Intiminators.

Hi Jack!
Thank you! 👍
I'm looking to do a 2 inch lift on my bike front and back using Trike tubes upfront on a 22 Street Glide Special.. I'm intrigued to say the least about these valves.. I'll be spending $1,500 + mounts on the back I did not want to do that again upfront with cartridges.. I figure the forks are already built why can't you just improve them?..
As I understand it talking about single circuits.... Cartridge's are single circuit but one cartridge handles compression and the other handles rebound so each fork tube is working dedicated to something independent of the other side...I'm no engineer but to me fork tubes trying to work together should not have apposing force in opposite directions for felt stability, seams like it would be prone to a measure of binding....now they do run that system in track bikes for reasons only they know...
If I understand video correctly these valves are the same in both fork tubes and able to function dedicated 100% to compression and rebound without compromising each task / circuit by use of the inertia valve... Have I got that right?
As long as spring pressure on inertia valve is worked out and longevity is reliable it sounds good.
That is an interesting project you are undertaking.
Your question- "If I understand video correctly these valves are the same in both fork tubes and able to function dedicated 100% to compression and rebound without compromising each task / circuit by use of the inertia valve... Have I got that right?"

I'm very interested in this product...........I just recieved a Wilbers nivomat complete suspension for a 2016 Road Glide Special. The rear shocks made a night and day difference on my bike, but I have yet to install the new springs and fork oil. After seeing this video I am inclined to install the "intiminaters" , this would be the perfect time as I am rebuilding the forks anyway. My question is, (the video describes the intiminaters as "using lighter oil" what viscosity is recommended? Can I use the fork oil from Wilbers that came with my new fork springs? (The bottle describes my new oil as SAE 10)
You have 49mm forks and the proper oil weight for Intiminators are the 49mm forks is 10 W, so you are good to go.

How does this compare to the AR-25 axxion rod damper kit?
We have done extensive testing of the AK-20's, but very little with the AR-25's. From our initial testing, we have not noticed a difference between them and the Intiminators...HOWEVER, we are not done with the objective bump and brake dive testing. Until we do complete that, we cannot say with certainty. Thanks for asking, it had dropped off our radar when the bike we were testing on was sold before we could complete the testing.
We need to get another set and start our testing over again.
KP
So you just install the intimadaters, no drilling of the dampener rods to take them out of the equation?
That is correct. The GV emulators require drilling and then adjusting. The Itiminators are a straight drop in. They dynamically adjust and a lighter weight oil is used to take the damper rods out of the equation.
Here is a video that you may find interesting/useful- ruclips.net/video/0YevsSYiyqw/видео.html
And here is a report where we compared many different front suspension options, including the GV's- www.dkcustomproducts.com/dk-custom-front-suspension-testing-report-part-i-of-ii-dk-fs-tst-rp-i.htm
The weight of the oil can affect the speed of the shock movement ???
Yes, the viscosity (pour rate or thickness) of the oil will affect how fast or slow it travels thru the various compression and rebound valving circuits. This has a direct, and significant, effect on how fast the shocks or forks move.
Do you have an application for a 2005 Dyna Wide Glide, with
41 mm forks?
I have installed a Progressive Suspension lowering kit in the forks, lowering the forks 1.5."
Can I still utilize these valves with the lowered forks?
Yes, we make 41mm Intiminators, and yes, they will work with the lowering kit you have in your '05 Wide Glide.

The only difference is that you will need to pull your fork tubes off the bike on the Electra, can't do it with them mounted. It adds about 1 hour to the process. You do NOT need to remove the inner or outer Batwing fairing.

I am going to buy your product I think it's great, but the presentation was horrible sorry guys...
I have pro actions on the rear was considering doing the pro action front fork kit so are you suggesting using both for the upgrade?
We have tested them out, and the PA front fork kit is a definite improvement over stock.
Using the Intiminators alone are an even better improvement...and less expensive.
You can use the Intiminators with the PA Fork Kit, they will work well, but the incremental improvement will be small.
Have a 2017 road glide ultra...would I need to change out springs or will they work with the stock ones??? What do you suggest?
They will work well with the factory springs as long as the rider weight is 250 lbs or less. If it is more, OR, if you prefer a more firm/aggressive ride, then you can do one of two things:
1. Make you spring spacer (simple PVC pipe) longer
2. Get some stiffer springs (linked below)

Great product and understandable information in your video 👍👌
I have a 2017 Dyna lowrider s and have put progressive springs and the heavier weight SE oil in which I believe is 15w instead of the standard which I think is 10w, to take out some of the dive. Would these suit my shocks considering they are different to standard in other models because one side is compression and the other rebound instead of both the same? If they will suit should I put them in with the standard Weight oil (10w I think) which is recommended for the progressive springs anyway..
Would the 10w oil flow through the intiminators better than the 15w and therefore work better in this situation.. I weigh about 80kg, around 175 pounds if that makes and difference, and ride fairly aggressive most of the time..Any advice would be much appreciated..
Thank you, glad you liked the video.
Your 2017 Low RIder S has a cartridge in one of the forks. These do not work with cartridges. There are a few Models throughout the years that Harley has used a Spring and Damper Rod (Tube) on one side and a cartridge on the other. These do not work with cartridge style suspension.
*Many Customers have replaced the cartridge on one side with the standard damper rod and then used the Intiminators with good results.
If you replace the cartridge with a damper tube and springs, then, yes, on your 49mm forks you will want to use 10w fluid for the intiminators to work properly.
The Intiminators will reduce brake dive significantly.
@@DKCustomProducts looks like I've got a bit more homework to do on this then..Thanks for the reply 👍
So I'm keeping the wheel on the ground through bumps right?
Yes. Keeping the tire on the ground for stability & control, while keeping the bike level (not bouncing around) is what these do. 👍
In my mind any bending/flexing part of this gadget will wear pretty fast.
The shim stack, which is the flexing part of the valving is something that has been used for decades in higher quality suspensions. They do not wear out.
We've pulled apart shocks and front forks that have had them running for over 100k miles and they are the same as new.
Just curious how much fluid does the average shock hold?
It all depends on the bike...not just the year but the model. It could be as little as 6 ounces per fork to as much as 24 ounces per fork.
How is this new system going to affect the rear shocks?
We made a video on that subject, you can see it here- ruclips.net/video/v4DjARmEZN0/видео.html
Will these work on 2019-2020 CVO Road Glide Forks? I understand they are different than standard Harley forks due to the 21” front wheel. Any thoughts?
Yes. The forks on that model are the damper rod style and these are designed to work with them.
Newer Road Glides with the 49 mm forks have the Showa Dual Bending Valve architecture already. I’m personally not convinced that the Intiminators can be effectively used in conjunction with the SDBV system because you’d be trying to have two differently designed valving systems in play. DK needs to specifically address this issue in a video to clarify the pro/con on the issue.
@@RoadieWingZZ Yes, some have the SDBV in them. (they only used them for a couple of years, then stopped because they add little benefit) They are a single valving circuit. They do not dynamically adjust, and they do not provide anywhere near the compliant, planted, comfortable ride that the Intiminators do...for the reasons outlined in this video.
Remove the SDBV and replace them with the Intiminators...do not run both.
One thing I’ve always wondered is if each fork leg is doing its own circuit, would that make each fork leg flex differently? Like is only one leg working at a time and would that make each leg flex differently and would that effect handling? I could see it not making a noticeable difference for a light dirt bike or sport bike, but have reservations about a heavy touring bike. That’s the only reason I’ve stayed away from a separate compression leg and rebound leg. I have zero facts or knowledge to back that up. That’s just what’s in my head. Any clarification on this would be greatly appreciated and save me a ton of money not buying cartridges
Your concern on the forks is also the same as having different shocks on each side of the swingarm.
As long as the fork tubes and triple trees are engineered heavy enough, they will keep both forks rigid and working together, even if one is primarily compression valving and the other rebound valving...or if they had different weight springs in them.
The same applies to the rear...as long as the swingarm is stout enough, the shocks can be different.
Fortunately the 2009 and up HD Touring bikes have a good stout frame and font and rear forks.
With the Intiminators they both work the same. They are not asymmetrical, so that is a non-issue anyway.
@@DKCustomProducts Ok! Thanks! Yea I’ve always hated having the Harley stock different shocks on the rear for the same reason. I figured the engineers were smarter than me but was a question I always wanted to ask. You guys are the best. Thanks for the response
@@herbolmstead5938 Thank you for the kind words. Appreciate it.
Where are you guys located
Northwest Mississippi, in Hickory Flat.
Inertia and gravity works the valve for wheel input? High speed rod travel?
Slower speed, can travel uses shims for valving?
Yes, you are correct. At higher speed rod travel, from the wheel hitting a bump, the IAS valve opens to keep the bike stable and smooth. At slower speeds and when there is chassis input (like from putting on the front brakes) the shim stack is active for the valving.
Hey guys ... I was watchn a video in which you said after 10000 on a m8 114 look for a leak in the engine . i forgot what you said but it was like test on the engine you want to get done b4 the warranty expires . can you remember what its called.
I believe what you’re talking about would be a leak down test. Check out Kevin Baxter Pro Twin Performance here on RUclips to learn more about your M8.
@@mentz8915 holy moly.....thank you sooooooo much..... I have a 2021 with 8000 on it and when im highballing it ie throttling 1234gears over 4000rpm my engine cuts down or chokes out immediate decerleration.... Why would it do this?
As Mentz891 said, you may be thinking about a leak-down test. We talk about it in this video-

@@phillipmckeownakalucifer.6689 If it is cutting out, are you sure you are not hitting the rev limiter?
If not, it could be a variety of things-
Dirty fuel filter that is restricting fuel flow
Bad plug wire, coil connection, spark plugs
But it really sounds like you are hitting the rev limiter.
@@DKCustomProducts whats a rev limitet
Im looking to upgrade my 15 v rod muscle. I have been looking all over for a good upgrade for the front as i am from the sport bike world and ride my v rod like a sports bike. Will these work for my application?
I wish we could help, but we have no experience at all with v rods. Thanks for checking. I would hit up the vrod section of the HDForums and ask the folks there what their experience has been.

@@jasonwillis6362 Cool, glad to hear!
Great info 👍

Tunable Front Forks I like this Idea. Is there a way to make these work for the rear shocks as well??
Yes, good idea for both forks and shocks.
DK has licensed this technology and has started putting it in rear shocks also.
We have released the 14" NexGen™ Trike Series Shocks™ with this technology and it is amazing how well they ride.
We are almost done with all our testing on Sportster, Dyna and Bagger shocks. We anticipate these being released in a few months.

@@DKCustomProducts I have a dyna lowrider and vey interested in this front and rear set up. thank you for the reply
@@user-qw3zt9vl4n It'll be a few months before the rear shocks are available for your Dyna...but when they are, I know you will be well pleased with them.
do these work with the progressive monotube kit system . Progressive Suspension’s state of the art Fork Cartridge Kit ??
No. These are plug n play for damper rod set ups. If you have a cartridge system, you can replace it with damper rods and the Intiminators.
Are these for front and rear suspension?
They are only for front suspension. The technology is used in some rear shocks we make, that can be seen at the link below...it is utilized a little differently, but very similar principles.
www.dkcustomproducts.com/dk-custom-nexgentm-14-trike-series-shockstm-for-harley-davidson-trikes.htm
Next thing this guy has to work on is the mono shock for newer Harley's.....my 2020 Heritage is shit....I mean spine crushing bad.
That is on the list, but pretty far down.
We have many hours riding M8 Softails, including the Heritage. We have not found the rear suspension to be horrible. From what you describe, if you have tried adjusting the shock and it is still a piss poor ride quality, I would be checking out the shock to make sure it was not defective.
@@DKCustomProducts How would I check for a defective shock?.My local dealer where I bought the bike is shit and will just tell me that's how the bike rides.
@@stevencorry5790 If you have already tried all different adjustments (ignoring the manual, it is notoriously off) and can't find a good ride...
First thing is to look at the shock, see if there is any oil leaking out of it anywhere. If there is no oil leaking, then the next thing I would do is find another 2020 Heritage. Make sure the tires are at the same PSI as yours, then adjust the shock to the same as the best setting on yours, then ride it. If it rides significantly better, then, you can fairly safely conclude that some is awry with your shock or swingarm.
I have a 2005 Soft Tail Deuce custom.Once in awhile when I'm riding I can fill the front forks bottom out.Iv had the bike for almost 5 years It's has been lowered before I got the bike.My question is when I start to rebuild the front forks what would be a good product to keep them from bottoming out each time I hit a bump Other that the forks hitting or bothering out from time to time it's a great bike.It seems the Deuce is a oddball but iv not seen to many or none at all were I live.Any advice would be appreciated.Only has just over 11044 miles.Even those that's low mileage for the yr it is it just fills the forks need to be rebuilt and thought maybe adding a stiffer set of springs when I start the rebuild.
Using the Intiminators will preserve your travel, so when a large bump is encountered you will be much less likely to bottom out.
If you are having too much sag, you can go with a stronger spring, OR make your pre-load spacer a little longer.
Can these be used with the Pro Action fork kit that replaces the stock damper rods?
Yes, they will work well with that kit. 👍
Hi I installed the inteminators on my 2009 road glide with a 26" so the travel is limited so I still bottom out if I ues 15w will it be too stiff...??
Do not run a heavier oil with the intiminators. They are very complex, with many small ports, designed specifically for the weight oil.
Since you have limited travel, to stop the bottoming out, add more pre-load to the springs.
When I was changing my spark plug on my street 750, I saw that there was rust on the piston head, Why is it so ? How can I get rid of rust on piston ? I have Street 750.
We do not have much experience with Streets.
It is water cooled, perhaps there is a leak?
Are you sure it is rust and not carbon build up?
Sorry we could not be more helpful.
@@DKCustomProducts I dont have any coolant leak and there is no sign of coolant loss, can the carbon buildup be brown colour ? The engine is running absolutely fine. Just worried about brown coating on the piston crown.
@@khanibrahim5947 Sounds like carbon and/or oil build up to me. Take a look at the photos in this link- www.dkcustomproducts.com/overview-of-external-breather-systems-ebs.htm
Are these gonna be available for the 20+ low rider s with the upside down tubes?
The LowRider S is a 43mm inverted fork. There is no current plan to make Intiminators in the 43mm size. They are available in 39, 41 and 49 mm.
Thank you for asking.
@@DKCustomProducts is there a reason why no one is making these for these forks? There’s a hole in the market for something like this for the low rider s and fatbob
@@ItsEvilJohn Like many other things Harley has done, waiting to see if they stick around or are just a few year anomaly. There are significant time and cost involved in developing a new part...doing so for something on a Harley that is not going to be around long term...it is usually not worth it.
Great video and explanation. Will you be doing an install video?
We have not done a video on it. It is a super easy install, you can see the written instructions at the link below.
We may do an install video at some point...gotta get a bike that does not already have them installed.
www.dkcustomproducts.com/media/wysiwyg/Intiminators_03_24_22_-_Google_Docs.pdf
So can these be used with a cartridge system?
No. These are plug n play for damper rod set ups. If you have a cartridge system, you can replace it with damper rods and the Intiminators.
Excellent explanation.
Glad it was helpful! 👍
Interesting that the final consensus is that a well made fork cartridge system is sub- par a/the above suggested product and set up . It seems the better cartridge systems (like Traxxion, and Legends) have separate Rebound and compression ckts (Rebound on one side of fork and compression on the other) Is this guy ignoring these types of cartridge systems with is comparison (?).. though not far behind but that's not what your DK testing has revealed in your system ratings.. putting a Cartridge system at the top of the survey.
In our report list are the popular progressive cartridge systems which tested out much lower than the Intiminators in this video.
The FST Cartridge system is better than the Intiminators also, but available for limited models
However, the AK-20's are also in the report list, and they tested out much better than the Intiminators. This is our experience from our extensive testing on the street.
See Comparison Report at this link- www.dkcustomproducts.com/dk-custom-front-suspension-testing-report-part-i-of-ii-dk-fs-tst-rp-i.htm
Not included in our report are the two different times (once 7 years ago, and then we tried again in 2021) of the Legend Axeo cartridge suspension. Both times we were very disappointed in the performance of these cartridge systems.
We actually recorded a test ride video last year, thinking that they finally had it dialed in. While it was better than stock, it was NOT better than the Intiminators. Since they were such a disappointment, we never did anything with the video.
@@DKCustomProducts Ok, thanks for the clarification, and additional information on the legends too.. you guys always seem to report it as you see it.
@@ut1004bp Yes, can't tell you how excited I was to test the newest Legend Axeo's. Had the gopro going during the test ride because I thought this will be a good live test that would get my comments as riding of how nice they were.
Instead I was dumbfounded & disappointed by the ride quality.
They are popular, and we could sell a lot of them. But they are NOT a good value for the $. Most unfortunate.
Conversely the AK-20's provide an astoundingly better ride quality. As noted in the report, the FST's are nice also.
But the best improvement per $ spent are the Intiminators.
@@DKCustomProducts Yes, I'm on the shorter and lighter side and I am leaning to Progressive springs and Intiminators mod.. I'm thinking about long term consistency and durability and at the moment, I believe they might be a better choice overall.. I dont like the Idea of Progressive's single, double heavy shock (0nly on the right side of the fork)
@@ut1004bp I hear you. I believe you will be well pleased with the springs and intiminators.
Do this fit a 2018 Fat Boy M8 Softail?
Yes, these are plug n play for your '18 Fat Boy.
@@DKCustomProducts With that, they are now on my wishlist for my suspension upgrades. Though I'd like to see an install or instructions video that demonstrates how to get them in there safely and reliably.
I think these would be a great combination to go with my Fox rear monoshock.
@@FranBunnyFFXII I think you will be well pleased with them.
Here is a link to the instructions. It is very simple...push them into the tube.

I am sure that we will do a video on the install, just not sure when.
Thank you for looking at our parts. 👍
Over-priced BS!
These are $200 and not even $20 worth of materials and machining involved!
There are better options! I know what I'm talking about, I worked in high performance auto for years, made trannys for NASCAR to name a few! If this were priced at $50-$75 then maybe! Plus most of their links on this page don't work!
Everyone is entitled to their opinions, even if they are not based on facts.
The cost for the CNC machined parts, not counting the Delrin, o-rings, wipers & more, exceed $20 per fork by quite a bit. CNC machines are not cheap, labor to run the CNC machines is not cheap. Then you have the labor to assemble them.
Your WAG is not even in the same universe as reality for parts made in the USA.
We wish it was, then they could be had for less.
Check out the videos below to see some of what is involved.
ruclips.net/video/Ps48FL7XU8A/видео.html
ruclips.net/video/pi9Zkuv8HM0/видео.html
And, probably the most important factor...they will make the front suspension ride better than many of the $600 to $1000 front suspension kits out there. :)

P.S. I think something must be wrong with you computer. I just clicked on every link in the video description and in the product page. They all work. :)
