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

Gloomy Wisconsin 🗑

Hell I live in California and I'm NOT California compliant .

The environment around that lift would be hostile.

I concur 💯

Good to hear my RKS is getting the Zippers468 next week

Haha. Glad you could relate.

It’s a fun bike to ride. I’m glad we were able to showcase the power

@@MattLaidlaw *Yeah all of us feel the same **#Matt**.*

Dang. Very nice

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?

@@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.

You can have fun on your 04 Road King. Things change in life and hopefully you can get another hot rod Harley again.

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.

Oh nice 👍🏼

Thanks for watching my friend. 🤘🏼

Haha i know, I know

😃🤣 🇦🇺

I'd like to !

Rarely do we subject him to it but he knew what was coming that day.

I appreciate your approval.

@@MattLaidlaw As a master home mechanic and a degree in learning from RU-vid, I have to watch out for the little guys. Just in a day's work on the couch, man. Seriously though, that beard is dope! Lol

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.

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.

@@RedTickJJ exactly man.. just a dick comment.

Yea, I don’t know how he did it

@@MattLaidlaw #Lol 😆😂🤣😜

I fitted a set of s&s 433 Johnson rods to my 2020 road glide 350gt.what a difference oh my god!

what bike did you do this on?
