S&S 475 Cam Upgrade on a Harley-Davidson M8 Road King

The boys at Laidlaw's H-D Install their favorite Cam, the S&S 475C Cam. Get a detailed look at the Cam installation and everything that goes with it. Andrew then takes his 2017 Milwaukee-Eight Road King out for a twist-of-the- throttle with the new cam installed on his stage 4 Screamin' Eagle Setup. This cam with the tuner is California legal so it can be ripped guilt-free.

[@fxlrsaz6363]

John, is a very patient person with both of you!

[@ocglide2566]

It's really amazing how much you get from a cam upgrade on an M8, I spent a fortune on my old Twin Cam 96 to get that big a boost in HP and Torque. I did a cam chest upgrade on my 2019 RGS, I used all S&S parts except I went with the Red Shift 468 Cam. For me the Red Shift 468 delivers the power right where I live 2500 to 3500 RPM. The SS 475 seems to work better for someone like Andrew that likes to rip the throttle and probably lives in a Higher RPM range than I do. Ofcourse Zippers Red Shift Cams aren't CARB approved so if that matters to you in Cali the 475 would be the way to go for sure.

I installed an S&S 475C cam chest kit on my 2019 RGS a year and a half ago.It turned a nice bike into a hot rod.Here in Ohio we’re able to have our bikes custom dyno tuned for perfect af ratios so not only do I have great performance my mpg is in the high forties.

[@MattLaidlaw]

Dang. Very nice

[@tyroneshoelace4872]

Can I ask... I'm considering a cam for my M8 114 with the S&S 475c being one I like. But I've heard and seen dyno graphs (even on S&S's own website) that say there is zero gain in hp & torque until you reach the upper rpm range. So high that my bike never gets there. What have you found?

[@cres7795]

@@tyroneshoelace4872 Best cam choice is the 30/30 From star racing. Best sounding cam and Best performance gains. I did the 475 on my SG and the 30/30 on my RG, the performance gain over the 475 is noticeable. The 30/30 you get your main performance gains in the lower rpms.

[@Big88Country]

All I can say is, John, YOU ARE AWESOME BROTHER! 🤣🤣 Great job guys! I personally went with the Star Racing 3030 cam with a 485 lift. Had to change the oil pump because it was starting to sump, so I figured might as well put a new cam in while I had the old one out, RIGHT!! Everybody does this right? It gave my mostly stock 2017 CVO Ultra 114 a big boost. It turned out 115 HP and 120 Torque. It has that snap your head back power, it's great! Everyone likes the S&S 475, it's a great cam as well.

[@Lucas_FLSL]

What I like the most is the G-Shock 😇! Andrew is never late!

[@20sgcvo90]

Andrews and fueling both sell a lower cam sprocket that is a great upgrade and reduces the play in the stock lower sprocket. Runs about 65.00 and worth every penny.

[@haroldlanglois8986]

I have a Stage III in my 17. I've trashed the motor twice. Harley makes shitty high performance parts. Glad to see you going with S&S.

[@mojomanmurph1925]

I got the Harley Davidson 128 Big Bore installed right when it came out. Running the Pro Street and Auto Tuner. The SE oil pump and clutch. Using Fullsac MX header. (Throw said header pipe that comes with the stage kit away, that cat meets EPA but no good). Just put 20,000 miles on the motor running from the Cascade Mtns, Rocky Mtns, Application Mtns, deserts, plains, swamp lands and to the oceans. Ridden in all types of weather from 35 degrees to 109 degrees for hours on end. Still running strong. Not the engine to cruise around town stop light to stop light or get stuck in big-city-stand-still-traffic. She wants to run, needs the air to cool her down and a total blast when you get into the throttle. Very impressed with the Pro Street and Auto Tuner while touring. It changes for the weather conditions and altitude instantly. If you want good power from the get go of a brand new bike, you can buy a standard Electra, Street or Road glide and get the kit installed for a good price point. Get it Dyno'd not mapped. The dyno numbers of the 128 and 131 are very close you wouldn't know the difference. Also, Harley is always placing top 3 in King of the Bagger racing with S&S, Vance & Hines, Trask running their own bikes in the race. Something I have been paying close attention to wondering what really is the best out there.

[@tommiller8714]

Sounds great; S&S makes excellent products for Harleys. On my '21RGS (rare 1-yr. only Snake Venom/Black Pkg.), I went with the S&S 465c full cam chest kit, although initially I was leaning towards the 475 cam. Chose the 465 cam because I wanted the earlier torque hit; pulls great from just off idle (1750rpm-ish) to well past 4000rpm (perfect for my style of conservative riding, 2-up, hills, mountains, curves, etc.). Should I do a S&S 114/117-to-128 big bore kit (or a S&S 131 Stroker Kit, 4.625" stroke x 4.250" bore) future, I'll probably go with either the S&S 550 or S&S 540 cam, and of course will upgrade heads and Intake/TB/injectors, etc. My other mods: S&S 2-1 Sidewinder (w/catalyst); Fuel Moto/K&N # 3956 A/C (w/stock ventilator outer cover), Trask M8 Checkvent; HD Fan (oil cooler) and Tuned with Dynojet PV3-B (Map by Lucas at Fuel Moto). My combo runs excellent, pulls like freight train, and averages 46.4 mpg cruising on the freeway at 70-75 mph. For suspension: I'm running RWD shocks out back (reservoirs attached to the shocks) and a Progressive FST front end kit; working fine (was 1/3 to 1/2 lower costs than Legends and Ohlins).

Stage 4 build will go better with other cams. the 475 is not a super high lift cam. It's considered a bolt in. a higher lift cam would go better with a stage 4 build.

[@MattLaidlaw]

Yea, we wanted to put it up on the Dyno but didn't have the time. Like the other comment on here says, it probably doesn't hit the peak HP that the other cam hit.

You can have all the horsepower you want, but it’s the torque that’s going to drive the rear wheel. That’s what’s going to really make the difference.

Dang dude, I'm surprised you/they didnt address that OEM oil pump, and cam chest before, or right with the earlier stage 4 upgrade, I think a Stage 2 would be perfect for me, and my 107

[@feloniousmonk3049]

It's not the oil pump causing the sumping, it's the NPT tapered thread hole tapped too deep at the factory by HD that was causing oil pump pick up problems. The bolt was going in too deep and cutting off the oil pick up flow to the pump, causing oil to back up to too high a level where the crank would would then aerate the oil, beating it to a froth like a blender. See Feuling shorty bolt 1/2" x .260" instead of 1/2" x .460". Another easier solution would be to use more plumbers teflon tape , more layers of it, measuring how deep the bolt fits before you remove it, and then getting it to sit .150" to .200" less deep into the hole when fully seated. That leaves the hole unobstructed for proper oil flow pickup by the pump. HD made 8 iterations of that damn oil pump before they finally figured out the problem was the sump plug seated too deep. kzbin.info/www/bejne/mYjOZIpjqL9ljas

Well that puts that to rest. I was always under the impression that you HAD to go with that bigger cam when you go big bore, Stage IV. But I’m a torque guy too, not that I’m doing burnouts all over town, not worried about top end performance either, I just love that torque when it’s time to pass out on the trail, when you roll the throttle, the bike jumps out of its paint, you’re by the guy, and back into your lane. And of course the sound is like no other. S&S 475, Red Shift 468, you can’t ever go wrong. Great vid! You guys gonna throw it on the dyno for numbers and to see that curve?

Harley guys immediately jump on the engine to help performance. Weight is a problem with Harley. Replacing rims with carbon fiber would really help handling decreasing unsprung weight. Replacing the battery with a lithium would help. Does Harley make composite fenders to unload weight. Less weight helps everything from handling, braking, and acceleration vs just straight line performance. I enjoyed the video.
