Budget Friendly Upgrades to Stock Harley 103 Twin-Cam Engine to Increase Power and Reliability

What budget friendly upgrades should you make to your Stock Harley 103 Engine to Increase Power and Reliability? The guys at ‪@Zippersperformance‬ gave my Dad's 2013 Road King a wakeup of almost 20 hp & 20 ftlbs of Torque with their Red Shift RS528. This was a budget build. They were able to work with parts that I already had and focused in on Reliability.

My Dad can't get enough of how much more power his bike has with the addition of the Zipper's Performance BOLT-IN Red Shift RS528 cam. All of his buddies don't believe he only had a cam upgrade. Well, the proof is here in this video...

[@bullast2046]

Can you tell us the other parts you got him? Which can plate, lifters, oil pump, etc?

[@theodavies8754]

I have a Fueling 525 in an 88 Dyna with a stock CV 40. It's great to hear someone mention that the Dyna chassis has limits. I have twin disc on the '99 FXDL and the suspension is well sorted but there's no point going further. Clutch is uprated and starts to feel heavy after an hour or so. Also the 525 with Vance and Hines straight shots makes my ears ring for days even with full face and eye plugs.

People sleep on the Twin Cam 103 capabilities. I have a built 103 and when I tell you it runs hard, that’s an understatement. 114s with cams don’t even concern me. No cap, my boy got a 131 cammed and he jumped on me but i reeled him in once I hit 2nd gear and pulled away from him. When we made it to the next light his eyes was wide open and had to give my bike props. Don’t sleep on what a 103 can be. Mines is fully built, but it’s still a true 103. Your dad bike looks amazing too! I’m happy for him.

[@BuildRideRepeat]

Oh yeah! My Dad has been knocking off his buddies with his 103 since he got his bike back. HE LOVES IT! Thanks for the compliment.

My motor guy did all the work, he’s got a kit, it might be some more im missing, it’s his mix but it works really well. I highway ride too, fuel efficient and all of my Club bros don’t believe I have a 103 still, it moves!

He can't get enough of it. The bike is never in his garage anymore because he is always finding a reason to ride it.

Really enjoyed your video. I bet your Dad is very happy. I have a '12 FLHTC > 103ci looking too cam it and gets some more torque.

I love the color of your dad's bike! nice job on making it look great. zippers made it RUN great!

Absolutely love Zippers. Every time I watch a video from them I learn something new. I really wanna get my 16 RGS up there for this upgrade and a few other things. When is the results video gunna be posted? I'd love to see it. Keep up the good work and stay safe.

[@BuildRideRepeat]

THANKS! Yeah, I learn from those guys whenever I stop by for parts. Give them a call and tell them you're "interested in the RS528 for a 103 like the Build Ride Repeat video" The results are in the video, "I Surprised My Veteran Dad with A Custom Painted Harley-Davidson"

[@shannondickens3111]

ITS GREAT TO SEE A SHOP REALLY GO THE MILE AND CHECK EVERYTHING INVOLVED WITH CUSTOMERS CONCERNS ( GREAT JOB ZIPPERS ) IM IMPRESSED. MOST OF THE TIME SHOPS DO THE MINIMAL. ANOTHER THING ! WHAT WOULD THIS JOB RUN ?

[@BuildRideRepeat]

Yes! Their goal was to show their end users of Red Shift Cams the importance of doing a Bolt-In cam swap efficiently without throwing a bunch of money at unnecessary parts.

[@kerrylewis2581]

I "hated" my stock 2013 Ultra Limited engine and suspension. I ride in the mountains of New Hampshire, and the lack of early torque combined with a poor suspension made the motorcycle perform at a scale of 6 out of 10. I went with the S&S 551 cams, but I love Zippers products and would have chosen the 525. I picked up 20 ft pounds of torque starting at 2,000 RPMs. I also went with Ohlins front and rear. I now score my motorcycle at a 9 out of 10. As a bonus, the tune and cam also reduced the heat felt by my passenger and me. Worth every hard-earned dollar.

[@BuildRideRepeat]

Nice! A great tune will make a huge difference. I too am looking to upgrade my suspension after my MUSCLE 107 upgrade. I talked with a guy at the Öhlins booth during Bike Week and he mentioned they didn't have anything for the 41mm forks.

[@MAHGlie]

Great video. CV16 - USS Lexington? Very cool paint job!

Yes! Thank you! My father served on the Lexington. I painted it for his 70th birthday. I have a playlist for the build. This link is me giving him the bike after Zipper's upgrades. kzbin.info/www/bejne/hoLbgZ6vmLaoe5o

[@TheTunatamer]

What was the budget on that project? love the bike I have a 13 with 45k it needs a shot from zipper performance.

[@BuildRideRepeat]

🤫... My wife reads these comments. 👀 🕵🏾‍♀️ (It was basically cost of a cam swap and a Thundermax tuner.) Costs will vary depending on shop rates in your area. The money saved on new push rods can go towards new OEM rockers.

[@marvelharris9540]

In other words.. a couple thousand bucks@@BuildRideRepeat

[@1964ser1]

Big question what was the $ amount you paid ?

[@trailerparkcryptoking5213]

Now pulley it to gear it down a little for acceleration, it will still run out great in 6’th gear. The factory geared them to high for emissions....

[@BuildRideRepeat]

That may be true, but it was out of my budget to do any other mods. 😂 I was going for "Best Bang"

[@ronskelton8742]

No part 2?

[@gregduncan1001]

Never using zippers duel piston tried them one failed

[@bobcorio5145]

Did you end replacing the rocker arms?

[@BuildRideRepeat]

Yes, replacing the rocker arms are cheaper than paying to have them repaired.

[@wendimccain8580]

What was the cost? I'm looking to go stage 2, from stock, on my 2015 road king 103. I was thinking of going with an Andrews 48h or Woods 222. What are your thoughts? Thank you. Skip McCain

[@BuildRideRepeat]

This is what many consider a "Stage 2" upgrade where only a cam was added. I have no experience with those other cams, but the Red Shift RS528 is the TRUTH! I was able to ride my dad's bike to Milwaukee and I never needed to come out of 6th gear to pass anything. All the other was done because my dad never had any work done to the bike and we had no clue of the condition of his serviceable parts. The cost will be what a cam change would cost locally. For more about the check the link below for more info on the RedShift RS528. www.zippersperformance.com/red-shift-cams-rs528-for-twin-cam/

[@wendimccain8580]

@@BuildRideRepeat Thank you

[@bullast2046]

Anybody have experience with Red Shift vs Wood? I think any bolt-in cam is gonna be good, just curious

[@jjktmk14]

From all the videos I’ve seen, Woods get the better results.

[@juanz7908]

Are these good engines compared to the 96? Don't see too many on the road. Also hear they run hotter than the 96.

[@BuildRideRepeat]

I'm not sure of any temperature issues. The cylinder bore is the only difference in 96 & 103 engines. I believe the Red Shift RS528 will work with TC 96s as well. Give the folks at Zipper's a call. They should be able to give you an idea of what cam would work in your engine.

[@jaimebedolla989]

So if I pick up a 2015 103HO with only 1,550 miles on it would I still have to do all the reliability parts swap or would a 525 cam only be sufficient? And what kind of ball park $ is that ?

[@BuildRideRepeat]

WOW! That is a low amount of miles. The reliability upgrades were done to get my dad's bike to your bike's low mileage condition. Some of the parts replaced like lifters are serviceable parts that wear from use. Since it is a 2015, you will have the good parts in your engine. You will probably only need the Red Shift RS525 and a tuner. Give the guys at Zipper's a call. Tell them what you have and they will get you set up.

[@hootertexas9711]

@@BuildRideRepeat so if I have a 2015 103 I’m good with just the cam? This got my thinking I can handle this myself

I just had cyclorama 570-2 cams installed. In 2012 streetglide. Headpipe from drag specialties, vance and hines pipes. Sreaming eagle oil pump and cam plate. 98.7 h.p and 116 ftlbs tourque. Shaeffers H.D did the work in owigsburg pa. Top end is very quiet. 1 750 to 5 000 rpm. Cruises at 2 grand just fine. 44 mpg. It really rips.

[@BuildRideRepeat]

You'd be looking at the cost of a Cam Swap kit and tuner as your main parts outside of your exhaust and air cleaner. Both of those are usually done as a "Stage One" upgrade. Your labor cost will vary.

Cyclorama 570-2 just installed by owigsburg h.d. in pa. Got 98.7 hp and 116 ftlbs tourque. Drag specialties head pipe and vance and hines pipe. Top end is dead quiet. 44 mpg . Still can cruise at 2,000 rpms. It is amazing. K and n filter with stock airbox cover. Looks almost bone stock. It's on par with factory m8 114. 103 has nice thick cylinder liners that aren't prone to crack in the spigot area. Stock heads and jugs. Did this at 56,000 miles.
