Milwaukee Eight performance upgrades guaranteed to make your M8 motorcycle rip!

The new M8 motorcycles are hitting the streets. We have done hundreds of performance upgrades already on Harley’s new engine and the results are phenomenal. We have many stage 1 and stage 2 performance upgrade packages that make this great motorcycle one of the top performing engines we have experienced. Phenomenal performance upgrades are also available for 2016 and older twin cams as well. We are currently taking appointments at our Hartford City, In and our Fort Myers, FL location for performance upgrades, tuning and services.

We have tested several exhaust systems, motorcycle air intake systems and tuners on our dyno so that we can offer our customers the best of the best for their stage 1 upgrade. A stage one upgrade on this bike using the proper parts combination will definitely put more zip in your zag. Camchest upgrades are huge with the M8. As you can see from the dyno graphs below there is a lot to be gained. Cycle Solutions Inc. can help you choose the proper products and cam for your M8 build so that you get a top performing motorcycle from your investment.

This dyno graph shows the gain on a 114″ CVO M8 that had the HD 117″ upgrade done. Cycle Solutions Inc. installed a D&D Billet Cat Exhaust, Thundermax Auto Tune and a T-man T216 Camchest upgrade.

This dyno graph shows a 2017 107″ Road Glide that already had a D&D Billet Cat, Thundermax Auto Tune and our CSR intake installed on it prior do doing the cam upgrade which gained roughly 13 more horsepower over stock. We installed the T-man Performance T200 Camchest upgrade and gained another 14 more horsepower. Wow!

This graph shows a stock M8 2017 Touring motorcycle that started out around 75 horsepower. Cycle Solutions Inc. installed a D&D Billet Cat Exhaust, a Thundermax Auto Tune, one of our CSR Air Intakes and the S&S 465 gear drive camchest. Although this combination did not make quite as much horsepower, it is a more solid camchest because with the gear drive cam we eliminated the flimsy tensioner. This one produced more torque also.

D&D Billet Cat Exhaust system (matching ghost pipe available for wrapped bags)

Time to get rid of that plastic throttle body inside your M8 and unleash more power!

Cycle Solutions Inc. is known for their top performing throttle bodies. You can squeeze more power from your M8 engine by switching out that plastic stock throttle body and replacing it with a CSR 58mm throttle body. We are getting huge horsepower gains with the new M8 engines with a stage 1 and 2 cam upgrade so it is no surprise that there are even more gains to be achieved by getting that plastic stock throttle body out of there and installing one of our 58mm CSR throttle bodies.

The stock M8 throttle body is a 55mm and it has a plastic plenum that can change shape under load and also has been known to melt due to high cylinder head temps. Nothing is more disappointing then to take off an air intake to discover that the throttle body has failed.

Our high performance motorcycle throttle bodies are made from high quality 356 aluminum castings to ensure perfect OEM fit every time. They will not warp or melt! We utilize your stock core electronics and build them into a new throttle body casting, CNC ported manifold, complete with new intake flanges and seals. Our throttle bodies are compatible with stock map sensors, fuel rail and cruise control and are all designed to increase airflow and improve performance. We stock many styles of 58mm motorcycle air intakes that bolt right up and will complement any motorcycle.

Our dyno shows huge gains on the M8 engines when using our quality products. This dyno graph is for our 2017 Road King. We installed the D&D Billet Cat exhaust system, a ThunderMax auto tune module, CSR air intake, 58mm CSR throttle body and a T-Man 216 Cam chest upgrade. This bike gained 38 horsepower which is incredible!



We currently have throttle bodies in stock and ready for shipping.  2017-2018 M8 fitments require the core to be shipped to us prior to a new one being shipped out since cores are currently in limited supply. Click here to check out our throttle bodies or call Chris at 765-730-1646 and lets get you the performance you deserve.

Rinehart Racing is one of the first to offer products for the new 2018 M8 Softail Models

Not everyone is happy with Harley’s announcement of killing off the Dyna models in 2018.  Their new 2018 Softails will be a merge of the Dyna and Softail Big Twins and are aimed for the next generation of motorcycle customers.  HD will offer eight different models that are claimed to be faster, lighter and more nimble and Rinehart Racing has mufflers that will fit them all!

Whether you have purchased, or are going to purchase, a 2018 Fat Boy, Heritage Classic, Low Rider, Softail Slim, Deluxe, Breakout, Fat Bob or Street Bob we have you covered for mufflers.  These mufflers will be 3.5″ in a chrome finish with black classic Rinehart tips or you can purchase them with their new updated Slot style tip. A 4.5″ Black muffler is available for the 2018 Softail Fat Bob. Rinehart is ahead of the game being one of the first manufacturers to offer slip ons for the new M8 Softail line.

Orders placed now for these new Rinehart Racing Softail M8 slip on mufflers are expected to begin shipping by 11/15/17. Sounds like a nice holiday gift four yourself or a special someone….

Slip ons are a great way to gain some horsepower and sound out of your motorcycle.  The M8 motors are quieter than the older V-twin ones so changing out your exhaust on the new M8 will not give you the same sound gain that you get on the 2016 and older models but that doesn’t mean that you can’t get this new machine to sound like a Harley should.  Cycle Solutions Inc. has mastered the art of the cam chest on the M8 engines and offer several Cam Packages that will get you all the sound your heart desires as well as torque and power to the ground. If you are interested in a cam upgrade for your M8 then click here.

Is a Thundermax tuner in your 2018′s Softail future? It can be! Thunderheart has made an announcement that a Thundermax auto tune module is in the works for the new 2018 Softails as will be available soon. We will keep you posted on its release as well as many other new products as they become available.

New Arlen Ness Inverted Air Intakes available with a 58mm Backing plate

Cycle Solutions Inc. currently offers the popular Arlen Ness Inverted Air Intakes with a 58mm backing plate so that it can be used with a 58mm throttle body. A lot of our customers have or will do an upgrade to their throttle body.  If you go with a larger throttle body then you should also update your motorcycle air intake with a matching 58mm backing plate.  Even though many stock and aftermarket air intakes will bolt right up to the 58mm throttle body, the airflow is restricted and you are not getting all the gains from your throttle body investment.

Cycle Solutions Inc. sells the Arlen Ness Inverted Air Intakes with a milled out backing plate that will bolt up to a 58mm throttle body.  We have the backing plates milled out allowing more unrestricted air to pass through.  We keep the backing plates in stock and ready to ship out with any Arlen Ness Inverted Series Air Intake.

Already have an Arlen Ness Inverted Air Intake on your motorcycle?  If you already have one and just need the 58mm backing plate you can call us and order just the backing plate and we will ship it out to you. Arlen Ness offers this air intake in several styles.  The 10 Gauge, Deep Cut and the Beveled Arlen Ness Inverted Intakes are most popular.  Check out all the intakes available here.
