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

[@BuildRideRepeat]

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?

[@EazyDuz18]

what mileage was on it when you got the work done?

[@BuildRideRepeat]

@@EazyDuz18 It had about 19 thousand miles on it before the upgrade.

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.

How much horsepower and torque do you now have and how much did you beat the canned 114 by , also what bike do you have , I have the ultra limited and that will be a big difference I’m sure

[@cj8172]

Bro because of watching this video a few months ago I put in the Red Shift 528 cams in my 103 with a Thundermax ECM as well, my bike has gone from alseep to "best-mode". It's fast. So thanks man for putting me on to the 528 cams.

[@gw10758]

do you mean BEAST MODE? 😆

[@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.

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.

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.

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.

I have a 2012 dyna fat bob with a 103 I want to do this to mine whats the cost I should be looking at

[@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.

[@robertbarger6439]

@@BuildRideRepeat what if I have the stage 1 one already

[@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.

They are a maintenance item. You should be able to get good mileage out of them before totally replacing. I do believe the dual pistons keep better timing.

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.
