How to Install: S&S Cycle Cam Chest Kit on '17+ M8 HD® models

[@DONALD-MAGA]

Here is a Tech Tip for adjusting the pushrods. Leave your cam cover off while installing and adjusting your pushrods. With the timing marks lined up on the cam and pinion sprockets, you are at TDC on the rear cylinder. You can now adjust your pushrods for the rear cylinder. After waiting for the lifters to bleed down, turn the crankshaft one full revolution until the timing mark on the pinion sprocket is straight up again and the timing mark on the cam sprocket is straight up at 12:00 o'clock. You are now at TDC on the front cylinder and can adjust your front pushrods. It drives me crazy that these professionals making videos don't pass this tip along to you guys who are doing this for the first time.

I just put this oil pump in my 2021 Road Glide Limited. The one for water cooled. This was the only method that worked for me. Putting each component in at a time. That first piece is most important. If you don’t feel the oil port slide in. That pump won’t sit flush with the cam plate mounting portions.

[@petercolligan3679]

Just ordered S&S pump, camplate kit, precision lifters and cuff kit, after a major engine failure on my 2020 Breakout M8 at 6150km,s due to a screaming eagle lifter failure took out everything,including the crank. $9200 in parts, luckily 2 months inside warranty expiry. Interested to note, this is the third install tech video I have watched before foing the conversion, and you and another tech vid both advise push rod adjustment, after adjusting to 0 lash position of 4 complete turns. 1 of the tech videos states 2 complete turns after 0 lash position. I will be following the S&S tech video. Cheers for the clear instructions.

[@brandot.7466]

I love S&S, as the push rod adjustment they are confused!! all their push rods are 32 tpi this means to compress the lifter 0.100 thousands you need to turn the push rod 3TURNS +2FLATS to get .100 thou 4 turns gives 0.125 all lifters need to be collapsed 0.100 THOU after 0 LASH .EXCEPT solid lifters wich are used in rare racing applications ,I called S&S tech today and they said 4 turns is old instructions and 3 turns + 2flats IS CORRECT.!!!!!! ,4 Turns is not allowing the lifter to function as it was designed to HARLEY FUELING ETC ALL NEED 0.100

Easy to miss in this video. Make sure you have the tappets on the base circle before adjusting pushrods. Get the rear on the base circle. Install pushrods. Rotate motor until you are on the base circle for the fronts. Then install the pushrods. The twin cam SS video for this procedure explains how to get it to the base circle pretty well. Also, if you have the cam cover off, use the technique DON has described below. That's the way I'll do it next time. Little O

Hi Jason, fyi…the twin cam sprocket locking tool for 07-up will work with the m8. The tool for 99-06 tc-88s will not work with the m8. Different type of chain/sprocket on the earlier tc motors. At least that’s my understanding on the subject. I have an 06 softail, and a 19 rg. The tools are not the same.

Curious if using ass'y lube on the ball ends of the pushrods while installing is a good idea? Or is engine oil enough? Great video, thanks very much.

[@YoursInYeshua]

Thank you for the video! Just subbed. I will be installing this setup next month. Is that mini teardrop air cleaner 'hi-flow' enough for the 475 cam? I want it, but I'm worried it is too restrictive for say 110hp.

[@SSCycleInc]

It flows excellent!

[@YoursInYeshua]

@@SSCycleInc Per some calculations, I believe the 114 with the 55mm throttle body wants 285cfm of flow. What cfm is the tear drop rated at?

[@SSCycleInc]

@@YoursInYeshua Almost double your calculation.

[@YoursInYeshua]

@@SSCycleInc I see that K&N says their cfm rating can be found by taking the surface area times 6.03. So, a 2" tall x 6" diameter filter would have: 2" x 6pi x 6.03 = 227.3 cfm. That's why I was worried. And then you have the cover over it, further restricting it (imo). I guess I don't know how a covered filter that small can flow around 570cfm. Is there any website or video that you can point me to, to verify that, or to correct my math on? I'm an engineer and so when the math doesn't add up, I get skeptical. I really want the S&S teardrop (love the look and love that it would go with my S&S 475C cam chest kit I'm getting), so that's why I'm asking. For example, as a gut check to my math, K&N claims their extreme round air filter flows 350cfm, when left uncovered. To me, that makes sense with the math saying a regular round K&N flows about 230cfm. Maybe you are using a different, superior filter and not K&N and that where the difference is? Anyways, I appreciate any help!

[@SSCycleInc]

@@YoursInYeshua Can't really speak to K&N number nor verify their claims. We use a Superflow bench to test all of our air cleaners and we can share that there is only a 10 CFM difference between the mini and an open Stealth air cleaner. The mini cover allows for substantial air flow through the sides and back and flows far more than most engines will use

[@roach969]

Nope, it should've been on the opposite side of that tappet(exhaust), or on the bolt side of the inner(intake) tappet. This way, he almost made sure that the tappet will touch the cuff as soon as he torques it to spec and it rotates a hair. But of course he's the pro, and I could be wrong! LOL

[@darrinleazer6784]

Was just wondering if after you replaced the cam, did you have to put it on a dyno? Im still new with this' and was wondering.

[@elusivesambar8657]

Do you have to check the runout first to make sure it is below 0.005 ? What are the effects of installing the s&s oil pump and cam plate if the runout is greater than this? How does the effect differ with the stock components? (Chain drive)

[@SSCycleInc]

If you are swapping over to a Gear Drive cam, you definitely need to check the runout, if you are sticking with the chain drive it is not necessary.

[@jjones6173]

@@SSCycleInc Had two questions, this was the big one, the other was what is the criteria for deciding between chain or gear drive?

[@SSCycleInc]

Hey @@jjones6173,​ honestly the runout is going to be your biggest criteria. If your runout is not within tolerance you either don't have the choice to run the gear drive, or you have to take your bottom end apart, have it reworked by someone like Darkhorse, and then reassemble to run the gear cams. Or of course you can just run the chain cams. When it comes to decision making, other criteria (assuming you are withing spec) is if you would rather have a slightly louder cam (more engine noise) that transfers power slightly more quickly, or if you would rather have a slightly more quiet cam that requires checking at regular maintenance intervals.

[@jjones6173]

@@SSCycleInc I very much appreciate the explanation

[@michaelcullen9216]

I noticed you didn't check pinion shaft runout. Do you not suggest checking runout? If so just pinion shaft or counter shaft side too to get total runout?

[@SSCycleInc]

With a chain cam, it is not necessary to check the runout. With a gear cam, it is necessary to check for runout. You would base the runout tool off of the pinion shaft.

[@DONALD-MAGA]

@@SSCycleInc From the S&S instructions for installing the cam support plate: S&S recommends no more than 0.005” of total indicated runout on the pinion shaft while checked in the cases.

[@FranBunnyFFXII]

@@SSCycleInc I was under the impression you had to check for runout for the oil pump and camplate because this stuff is made out of 7075 Aluninium billet which does not compress and wears and cracks if the run-out on the pinion shaft is too much.

[@SSCycleInc]

@@FranBunnyFFXII Not sure what you're asking here. Runout spec we share is specific to the gear drive cams. The gears require a tight mesh and crank runout could cause interference. The material used for pump and plate would not be relevant to the runout spec.

[@raceboy1971]

@@SSCycleInc Moonshine Harley makes a big deal about checking the runout saying you will damage the cam plate in their KZbin video. They go as far as to say if it's over 5 thousandths, you can't install the cam chest kit, but they never mention that only applies to the gear drive kit, but that makes sense to me. I really want to do this install myself so is it safe to say if I go with the chain drive kit I don't need to worry about buying a runout checking tool at all?

[@chrisl.7345]

Remember to clean all the threads in the engine block with brake-cleaner to get rid of possible oil, otherwise the thread-locker will not work optimally,..AND be aware of the small tappet-cuff 1/4 screws,..they EASILY break if you don’t take your time and strongly recommendable use a heatgun ☝🏻

[@jamessouthworth1699]

When is someone going to come out with a kit for the twin cam 88 that eliminates the inner chain with a gear but still keeps the outer chain to absorb crank run-out?

[@jamessouthworth1699]

@J T J I already tried contacting S&S, Edelbrock, Woods, Black Widow, and a few others. I couldn't get anyone to make it. I guess they prefer to make cams that only halfway fix the problem. You're stuck choosing between total gear cams that can't tolerate runout or having 2 chains so one cam shoe is trapped behind the cam plate.

[@edwarner3826]

Just a question: @15:55 the bigger tooth is not facing up, but @16:25 it is. What did you do to get it facing straight up at 12 o'clock position?

[@SSCycleInc]

@@Old-n-slo-locked-n-leaned Gear drive cam allows for elimination of the wearable chain tensioner as well as more accurate cam timing. Crank run out is the only challenge for gear drive cams, as the gear is designed for a very tight tolerance and any run out on the crankshaft would cause interference. We would recommend the 465 or 476 cam on the M8 Ultra depending on the type of riding you are doing. 465 is more focused on torque and power down low in the RPM range and 475 will produce 100Hp, but does it much higher in the RPM range.
