Ultimate Trike Performance

Save 5% on Ultimate Performance Mods

(See Coupon Code Below)

 

 TRUE Stage I Upgrade is a sure fire way to increase performance.

BUT, having a free flowing air cleaner, free flowing exhaust, and a tuner is not the only way to get more power. 

 Whether you want to wake up your stock Trike with an Exceptional Stage I, or want to build your bike out to its maximum potential. 

Building a solid foundation is The Key to getting the most performance out of your bike, regardless of what Stage you go to. 

 

ULTIMATE TRIKE PERFORMANCE

(If you already have done a "Stage I" and were disappointed with the lack of improvement...this is for you)

 

 

 Combine the following mods on Your Trike for Improved Performance You Can Feel.

  

 





Outlaw HiFlow Air Cleaner System

External Breather Systems

DK Custom Harley External Breather System EBS Performance

 

Benefits:

  • K&N A/C Filter (million mile warranty)

  • Low-profile backplates for more clearance

  • Vents blow-by externally rather than back into your intake

  • Lots of options for routing your EBS filter or Catch Can

 

The air cleaner is the foundation that all other engine mods rely on and plays a huge part in performance. It’s simple really; engines perform better with cool, clean, oxygen-rich air. Thanks to the EPA, our Harleys are being choked out and can’t breathe, putting a dent in their performance. Having an air cleaner that doesn’t route that hot, oily, oxygen-depleted air back into your intake will help provide the Ultimate Performance. Also, having lots of routing options for your EBS catch can or filter is a plus.

Free Flowing Exhaust

Thunder Torque Inserts™

 

Benefits:

  • Reduced engine pumping losses

  • Better Fuel Mileage 

  • Increased Exhaust Gas Velocity

  • More Felt Torque

 

Technically speaking, exhaust systems cannot increase or decrease an engines power. However, they can have a profound effect on engine pumping losses, whether decreasing or increasing. The goal is to reduce engine pumping losses and increase exhaust gas velocity, resulting in more felt power at the rear wheel. Here’s a LINK to a more in-depth explanation of Harley exhaust and how it works. With the Thunder Torque Inserts™, you will have more low and mid range torque and the deeper, throatier sound is a plus. They’re also adjustable so that you can work with them until you find your personal “sweet spot” for tone.

 

 

Tuners

 DK Custom Dynojet Power Vision Flash Tuner w/ Auto Tune Stage 1 Harley-Davidson Fuel Moto

 

Benefits:

  • Cooler running engine

  • Improved Air/Fuel Ratio

  • Improved Timing

  • Smoother Running

  • Stronger Acceleration

 

Some bikes, Twin Cams in particular, run too lean from the factory. No matter if you have free-flowing exhaust & intake or keep the restrictive exhaust & intake, your bike will run longer, stronger, and more efficiently with a better tune. 

The Power Vision and the FP3 allow you to improve your AFR and Timing tables for a much better running engine.  They also have the ability to adjust out the decel pop if you do not like it.

Additionally, if you are so inclined, the Power Vision and the FP3 have a variety of gauges that you can monitor, in real time, the status of a variety of data points in your engine.  From MPG, to MAP, to Spark Retard, to Engine Temperature, and much more.

The XiED products improve the AFR, resulting in a cooler and smoother/stronger running engine, but don’t touch the timing tables.

Gas Tank Lift

DK Custom Harley Touring Bagger Trike Tank Lift Kit Better Air Flow Cooling

 

 

Benefits:

  • Redirects wind to the top of your engine (helps in cooling)

  • Plus of easier cleaning

 

Besides making your ride more comfortable, tank lifts also have a cooling aspect. With the tank lifted, the wind is no longer coming over the top of the tank and hitting the rider(reduced wind buffeting) and instead flows under the tank, over the top of the engine, helping to cool your engine down. 

 

  

Cooling Deflector Wings

DK Custom Cooling Deflector Wings CDW Harley Touring Bagger Trike Tri-Glide Freewheeler Better Air Flow Reduce Buffetting

 

Benefits:

  • Reduces air coming over/around the tank & between fairings

  • Redirects air flow to the engine (better cooling)

  • Reduces buffeting/ helmet glasses wobble

 

Most baffles and deflectors reduce rider and passenger buffeting but also reduce air flow over the engine making it run hotter and some bikes already run too hot in the warmer months as it is. With the cooling deflector wings, you can dramatically reduce the buffeting felt by both the rider and passenger while also helping to cool your engine, with that air flow now redirected over the engine. The cooler the engine, the better the performance!



 

Oil Filter Relocation

Black Hose Finishers Cool-n-Clean Oil Filter Relocation Kit For Harley Trikes DK Custom  Performance Sportster  Dyna Softail Touring Trike Freewheeler Big Twin Evo Milwaukee Eight Cooler Running Motor easy oil change

 

Benefits:

  • Puts your filter in the wind (better cooling)

  • More airflow to engine

  • Plus of mess-free oil changes

 

Relocating the filter puts it in the wind and allows more airflow to your engine. Plus, future oil changes will be a breeze with your oil filter now either mounted on the downtube(Sportster, Dyna, & Softail) or tucked in high and tight just under the left side passenger floorboard(Touring & Trike).



 

Performance Permanent Oil Filters

 

Benefits:

  • Superior Filtration

  • Reduced drag on oil pump

  • Finned Billet Case (little extra cooling)

 

Permanent oil filters offer many performance increasing features. With their high flow rates, magnetic pre-filtering, consistent filtering medium, billet outer housing which aids in cooling, and, unlike standard paper filters, a progressive rate bypass which avoids unfiltered oil bypassing the filter at startup and high RPM operation. The combination of these characteristics, dyno runs consistently show an increase of 4-8 Horsepower and in increase of 4-12ft. Lbs in Torque! 



 

Oil Coolers

 

It’s a given; oil coolers help cool down the oil and cooler oil/engine means better performance. It’s crucial to performance and engine longevity to cool down your oil. No matter which version you have, oil is the lifeblood of your engine and is subjected to intense heat.  It is crucial to performance and engine longevity to cool that oil down. If you have an air cooled twin cam with no factory oil cooler, you can get a side mount(downtube) or a low mount and typically see a 20-40* drop in temps. Using the Secondary/Auxiliary Oil Cooler with its patent-pending cooling bracket (see full details HERE), you can get an even larger drop in temps. Having the lowest possible engine and oil temps will result in the Ultimate Performance!

At DK Custom Products we use Jagg Oil Coolers on our own Bikes, and are happy to make them available to our Customers. The turbulators in each oil passageway gently stir oil, exposing it to more critical heat dissipation surface area for superior cooling with minimal oil pressure restriction.

Why Do We Use & Recommend Jagg Oil Coolers?

HyperFlow Technology is the engineered balance between performance and flow. It should first be described as a "systems" way of thinking.

Air flow, fins, oil flow, turbulators, brazing technology, metal finish, oil filter adapter design, thermostatic actuator, etc., are each components maximized to contribute to the overall system. It is only when each individual component is considered in relation to its contribution to the whole that a true systems approach can be claimed.
