One thing i didnt mention that I thought I had. Much of the extra power made by the S&S and Zippers cam could be due to another factor...to properly tune with a cat installed in the headpipe, the AFR should be a bit leaner than without to avoid overheating the cat. The leaner mixture could also have created an increase in the numbers. All this said...the manufacturers test their products and all we can assume is that they published the highest number they obtained in their testing with the stated equipment. Main point of the video is to illustrate again, how the cam specs effect the final performance and characteristic of the curves, and what each means. Hope you enjoyed it.

[@MechanicMax]

Sure did!! Hey Kevin...would like to call when your "not busy". LOL We are all busy...but have a question about the"old" fuel pack with the mode button and settings. It came in a Heritage I put based a while back. Didn't know it was on there until a few days ago.

[@jeffreyjones3228]

Excellent video explanation of how critical cam choice is. The M-8 motor HP is held back by low RPM operation. In your video building torque earliest and holding onto it longest, makes a very streetable, enjoyable bike to ride. Good Dyno numbers for a stock 107. Excellent video Kevin.

[@PotatoeJoe69]

Personally, I'm going with the S&S for my 107. It offers a huge boost in torque and power over stock, but as my only mode of transportation and something I rely on 100% of the time to get anywhere, I don't want to overstress the shit out of the engine and worry about it blowing up after 30k miles.

[@denniscicero6118]

Thank you mr Baxter, that was a excellent tutorial , I followed right along 👍👍I too, believe the zippers would suit my desired performance goals, again, outstanding, I’ll keep an eye out for more of your videos.. excellent….

[@richardedwin5980]

Kevin...thanks for that break down. Looks like I made the right choice in cams 7mos ago. I have a 2018 Road Glide Special. When I bought it I had a HD Stage 3 build done basically bumping it up to a 114. Everything used was HD except for the headers which were FuelMoto Jackpot 2-1-2. I used the Screamin' Eagle 4" Street Cannons & Screamin' Eagle Street Tuner. I ONLY went this route for warranty purposes. Respectively the dyno showed 113.84ft lbs tq and 109.24hp. This past April my factory warranty expired and I decided to install the Zippers 468 cam, S&S adjustable push rods, S&S billet tappet cuffs and S&S high flow oil pump and cam face plate since I was already inside the chest. I swapped out the mufflers to Vance & Hines Torquer 450 then had it tuned using PowerVision. I ended up with 140.33ft lb torque and 122.94hp. It is a beast now. A torque monster that hits hard at about 2750rpm all the way up through 4000rpm. I mean it is a rocket strapped to your ass when you twist that throttle!!!! And the "thump?" Yea...you can hear it!! Lol. Can't complain with the performance of this cam. This bike now has 50,500mi on it and gets ridden!!!! I don't beat the day lights out of it but she's also not treated like a queen either. Definitely recommend this cam to anyone who wants a good bump in torque.

[@getoffmygrass6974]

Woww!!! Such an awesome awesome explanation Kevin! I don’t find anyone on the KZbin explaining things so clearly as you do. I just subscribed to your channel. Count me as a loyal follower! I just wish you had included the SE447 cam as well. A lot of people whose bikes are still under warranty are forced to go with it to avoid losing warranty!! I had to use the SE447 in my 2018 FLHTK due to this very reason. Keep more videos coming in. Cheers!👍

[@KevinBaxter]

thank you very much. i didnt include that cam because it really doesnt compete that well. with the warranty issue....it has to be an epa friendly cam to work with the epa compliant street tuner...again for warranty. its a forced product and situation. so to compare it to others in the aftermarket, not really a comparison. I always like hearing suggestions on videos though...thank you for the comment and sub.

[@Tberg725]

If you're worried about your warranty no point in worrying about how much "power" it's going to make because your feelings are always going to be hurt when comparing them to a nice aftermarket cam reason I passed on the warranty most of the problems with the bikes are from HD parts 😎

I love youuuuu kevinnnnn,now i know whos the best

[@chopperjohn1046]

Great information video. I’ve been Cam Hoppin’ on my 131 M-8. Had a Zippers 468 in it for awhile. I just put in T-Man TMP-2652. It seems to have more power but it’s a gas hog...even without getting on it my best mileage is 33MPG. Seems to run hot too. I installed a Dakota Digital Gauge set at the same time. I’m getting head temperatures as high as 327 degrees on the freeway. The plugs aren’t white so I’m not running lean. They seem to be right. I don’t know what it was before I had the temp gauge but it seems awfully hot. Luckily I use Amsoil. I’m going to fashion some wind deflectors for the rear cylinder.

[@KevinBaxter]

468 is pretty small for a 131 man. 327 head temp (measured at the base of the plug) isnt too bad really. 33MPG is relative to how you ride it. If you regularly roll at 75 to 80mph, it will get much worse fuel mileage than averaging 65. advanced Ign timing will heat one up as well.

[@BladedAngel]

12:10 Good to know! I'm in the minority of thinking my FXDR's exhaust and air cleaner actually look fine on the bike, so I left them on. Before dyno'ing the bike the Dealer URGED me to get a "less ugly" exhaust & air cleaner combo and showed their Screaming Eagle and Authorized Dealer Catalog (S&S, Vance and Hines, etc.) and said I'd be missing out on big gains if I stayed stock...I ignored their upselling attempt and bought an Intake Manifold instead. Imagine their surprise when my bike dyno'd higher than most other stage 2 114's they had done... 125HP/128TQ S&S 475 Cam Chest Kit with Dynojet Powervision

Many thanks Kevin for this awesome Video! I will pursue the RS468 thanks to you! Another note. The only reason i switched out my stock chrome Exhaust pipe on my Sport Glide 2020 to V&H Pro Pipe in black is eliminating chrome. I believe Chrome belongs in the Bathroom xD. But hell, I didn't know that stock exhaust systems can actually perform equally as good as a "competition or whatever" aftermarket pipes. All those who wish to maintain lower emissions and decent sound to make the bike pass in the yearly inspections is very convenient too. Win-Win!

@@KevinBaxter I wish I lived in your area. Unfortunately, my location is across the Atlantic. But I will spread your words and follow/join! While you´re at it. I have a specific question regarding the RS468 and the SE447 Cam. Which one will yield best low torque given the numbers without increasing fuel consumption? If any? is the lower duration and a little higher lift of the RS468 the winner in that case? I have the Sport glide 2020, stage 1 with Diag4bike tuner (usb dongle, presets maps) and SE heavy breather cleaner and a V&H Pro-pipe with quiet baffle installed. Not sure if you can point me into any of these cams directions. Perhaps the Knight prawler 22x cam (very weird numbers on that cam) if its any easier, you can write me on messenger or email.

Great info, been watching your videos on the M8s for months. Have you done any testing with the Woods 22XE. Can't find those numbers (lift, int close, duration, centerline, overlap) for this cam anywhere.

[@jarrodwilson7702]

I went with an Andrew's m460 in my 107, it's a cam that seems to get no love. I think it goes great and with only 2 degree overlap and 20 degree intake closing I'm still getting great fuel economy. Everyone loves the 475 but it seems to drink the fuel and only really makes more than the m460 above 4500 rpm.

[@KevinBaxter]

I agree sir. Andrews has several great cams that largely go unnoticed.

[@g-man2045]

I recently put the zippers 468 on my 114 with vance and hines power duels with harley street cannon slip ons. This really woke up the bike. The shop that tuned it said at the very top of rpm range it shows bigger injectors and air clean would provide better performance at that range. I bought the cam because of its mid range performance for cruising and also for using the bike in slow skills practice. Your explanation are great and if I get in your part of GA hope to stop by.

[@nxyz906]

Do u know how the soundvolume and sound characterics is of the 468 compare to star racing 30 30?

[@Combatinho]

The higher the centerline number the wider the RPM range the lower the number the narrower the RPM range is. In cars a 114 CL is good for a long range of RPM. A 106 can is good for a sort track type car because it runs in a narrower RPM range.

[@paulhorvath9784]

Which of the Three Cams would offer Best Reliability or Be the Easiest on the Bike / lifters etc ,Would it be the Fueling ? I'm happy Enough with Power But Would Ultimately Love to Retain Best Reliability, would Going with an SE torque cam be the Answer or Leave it As is.

[@dondorfman3951]

Exhaust opening point at BBDC is an important factor in torque production. Lobe separation angle is also important. When looking at intake close as a torque factor lobe intensity is needed because we don't know the actual intake close, just at a .053" lift. Compression bleeds whenever the valve is not seated on the way up on compression stroke. Lift is relatively not significant when comparing these bolt-in cams with stock heads.Just my humble opinions

look for one with an earlier intake close, slightly shorter lift or duration on exhaust side. It's hard to say specifically with so many out there to choose from. Lets generalize and say keep it on the smaller side like a S&S 509, or one in the .500 lift range with say a 36 to 40 int close and 230 to 240 duration.

I like a cam for torque. I went with Harley's screaming eagle torque cam as I was under warranty. it feels fine. would been nice to have had it as a comparison. also I wonder how the feel is when you upgrade. does it take a big difference to notice. just curious. so if you go up 5 can you really feel it. or is it over 10 maybe.

[@KevinBaxter]

most people would never notice 5 ft lbs. many cant notice 10. hard to say. just about every cam out there in similar categories, will produce gains over an SE cam...they are very conservative and made to meet EPA regulations...so they can be tuned with an EPA compliant tuner eg Street Tuner.

@@KevinBaxter i agree. that is why when someone says they have just done a stage 1 and notice the difference I don't think so. I sure did not. not until I did the stage 2 and the S&S headers with a dyno did I notice the difference. thanks for the response.

[@KevinBaxter]

exactly. youre welcome.

[@andrescott534]

Great video, thank you. If the Zippers cam produced those numbers with a stock headpipe and slip ons then there seems to no point to buy a complete exhaust system. The only reason to buy a complete exhaust system would be for the sound. Am I missing something?

[@KevinBaxter]

GREAT QUESTION!!!! Was hoping someone would ask this. The number are great but....heat can still be a concern. Cats can not be tuned to the same AFR that non cat can. Add more fuel in the tune, and the cat gets hotter. Yes this can be done, and make great numbers....same numbers can be had without the cat, a slightly richer tune, and less heat.

[@andrescott534]

@@KevinBaxter Thanks for the quick reply. Great explanation. I have a 2017 RGS with stock headpipe and 4.5" rinehart slip-ons. I will likely get the zippers cam, air cleaner and a tune and then get a full exhaust system later. It should save me some money in the short but give me the performance I'm looking for.

[@KevinBaxter]

good plan sir. when you get ready to pull the trigger, let us know. Thank you.

[@Tberg725]

There is a reason to ditch the factory system on a bagger for example more power to be had with the fullsac pipe 👍

[@robertmason8341]

Around 3:30, I think you misspoke, as we know (and you had even just said) , intake closing builds cylinder pressure and hence torque, but you said with the s&s having the earliest intake closing will have the lowest torque. Seems the opposite. You paused and it seems like you might have just got things backwards in what you said versus what you were thinking. Anyway, I like the videos and only wanted to point that out because it was confusing and I replayed it several times to make sure I didn’t hear you wrong.

[@KevinBaxter]

Thanks for the comment Robert. What i was saying was "lowest torque" as in "lowest rpm torque". left a word out. LOL.

[@jaytouvelle2359]

My warranty for my 107 FXLR is almost over. Is adding a DND FatCat exhaust and Zipper cams or SNS plus a full air cleaner going to hurt my stock MC or make it better.

[@KevinBaxter]

tuned properly, it will certainly make it better. cooler, more power, etc. Give us a call at the shop tomorrow and we can help you get everything sorted out and on the way. Thanks. 6782269651

When we choose the stage 2 for the 114, which cam is installed for more torque?

[@KevinBaxter]

You have many many choices there. Please watch the video on "how to choose the perfect cam". It may help you. If you like, you can email directly and i can get the right cam to you for your riding style.

[@Davan514]

Kevin Baxter thanks for your reply but keep in mind that the stage 2 is done under the warranty that’s why I was asking if the cams from Harley are made by the companies you used for your video.

[@KevinBaxter]

There are VERY few companies that actually grind cams. Andrews, for example, grind for just about every independent you'll find out there. That being said, not all are of the same quality...heat treat, etc. Not sure who grinds HD cams now. Regardless, HD grinds have to be conservative and work well with the tuning system (HD Street Tuner) they offer and maintain EPA compliance. You'll leave some performance on the table going that route but you'll be able to maintain warranty. It's a choice.

Man i'd be pissed if I bought an M8 107 and put a S&S Cam in it. I've got a TC103 with the SE pistons, SE heads, SE 234E cams and a D&D Fatcat 2 into 1 pipe and I'm doing 96 HP and 108 TQ. It's on a conservative tune with a Harley Race Tuner. I'm guessing if I put SE 100 HP injectors, the bigger throttle body and manifold and tuned it I'd probably be in the 105 HP and 120 TQ range. You've pretty much just inspired me to find a nice used 103 Electraglide for a touring bike. Really no reason to buy a M8.

[@Tberg725]

This inspires you to pass on an m8? That dont make much sense the m8 with just a cam and tune makes more power than your built TC lol

@Howard S Yes. Every OEM of every vehicle tunes their machines to the lowest common denominator among their customers. Leave it stock and you will ride safe and reliably with optimal fuel efficiency for many miles, and preserve the resale value. Tune it and you will loose or risk reliability, safety, durability, fuel economy, or all four. Don't forget that Japan ate Harley's lunch on these traits for decades.
