Amazing gains with the switch of a Spark Plug! Check out the NGK Iridium CR9EIX for the Milwaukee-Eight Motorcycles


Looking for a cheap upgrade that really does produce? NGK is the answer.

With our recent purchase of a 2018 CVO Road Glide, Cycle Solutions Inc. decided to switch out the stock spark plugs and install 2 pairs of the NGK Iridium CR9EIX Spark Plugs and perform a dyno test to see how these plugs compare on the new M-8′s to the Twin Cams.  Its no secret that Cycle Solutions Inc. has always been a fan of the NGK Iridium Spark Plug and recommends them for every Harley.

This dyno test was done while our CVO was bone stock.  The base before plugs shows 84.8 horsepower and 97.02 ft lbs of torque.  We did another dyno pull after switching to the NGK Iridium Spark Plug CR9EIX and the results are just as we expected them to be.  We gained almost 6 horsepower as well as 5.52 ft lbs of torque.  All by just switching out the spark plugs! Purchase your plugs here.

Twin Cams also benefit from NGK Iridium Spark Plugs.  Twin Cams gain almost three horsepower from the use of these plugs.  Check out the graph and see for yourself!

Product details:

  • The ultimate in spark plug technology and performance from the industry leader

Not all performance shops give you performance…This is a perfect example!

Cycle Solutions Inc. takes pride in providing customers with performance upgrades that really make their motorcycles rock.  There is a recipe to performance and we have done our homework over the years on quality products and the proper combination.  Recently someone visited our shop in Fort Myers, FL because he was disappointed in his motorcycles performance after taking his 2006 Street Glide to another local shop.  We had spoken to this potential customer about our services and products and quoted a price to get the job done.  Unfortunately, he had decided to take his motorcycle to another local shop to have the upgrades done for reasons that we do not know and the results were terrible.  We put his motorcycle on our dyno and all we could say was “Wow”. It was one of the worst running motorcycles we have seen across our dyno in a while.

First, lets take a look at his bill below (shop information has been removed). As you can see he paid a very large amount of money for engine upgrades.  This is a nice list of parts and should for the most part increase the performance on the motorcycle.  Instead of receiving a rocking machine, he got a motorcycle that performed less than stock and ran absolutely terribly.

Unfortunately, this customer ended up with a very sad running machine.  He spent roughly $8400.00 for a motorcycle that performs worse than a stock one.  His dyno graph below tells all.  His motorcycle barely made 60 horsepower and with the big bore upgrades he paid for he should at least be over the 100 mark.  His air/fuel ratio is not even close.  The dotted red line represents a perfect air/fuel ration at the bottom of the graph and his curve is so far off that we can not decide if the Power Vision tuner he had was just for looks because it was clearly not setup to do any proper tuning to his motorcycle.  His bill does clearly state that his bike was tuned and taken for a test ride.  One ride on our dyno and we knew this motorcycle needed surgery and asap!

First thing that needed done was to replace the exhaust that his motorcycle had that was robbing his motorcycle of performance.  A quality exhaust is the key and this customer had SE mufflers that had the baffles removed along with a true dual header that appeared to be home made.  The shop that did the work to his motorcycle installed torque cones into his exhaust.  Torque cones are a thing of the past,  We have never been a fan of torque cones anyway and with today’s top performing exhaust systems there is no reason for them, if there even was a reason, and no reason to take the baffles out of your exhaust.  We can not talk enough about investing in a great exhaust system.  We installed a D&D Fat Cat 2 into 1 exhaust because top performance needs proper supporting products!

Secondly, the power vision needed to be replaced with a Thundermax Auto Tune with a professional tune for the engine build.  Power Visions when set up properly might be OK for a stage one but if other upgrades are in your future or you are all about top notch performance then invest in a Thundermax and have it professionally installed and tuned by Cycle Solutions Inc.

We cracked open the camchest and tore down the big bore upgrades to inspect what he had.  The local shop had used stock heads with a set of poorly bored out cylinders.  This motorcycle had no compression. No wonder it was struggling.   We replaced the cylinders, heads and pistons with a 98″ big bore kit from Zippers and upgraded the throttle body to a 55mm because this should be done when you are doing engine upgrades.  Larger lift cams and bored cylinders and heads allow your motorcycle to take in more air for better combustion.  Leaving a restricted stock throttle body on your engine will restrict the amount of air flow that your engine can breathe in, potentially robbing the engine of power.  A quality air intake is also required so the engine can breathe so we also replaced the modified stock intake that he had on his motor with one of our CSR Air Intakes.  Luckily we were able to re-use the S&S camchest that was previously installed.

Lastly we installed a Rekluse Torqdrive clutch that is designed to handle high horsepower builds.  This is not an absolute necessity, however, the stock clutch is not designed for large amounts of horsepower and will begin slipping eventually and need replaced.  The Torqdrive clutch is a well built system and puts the power to the ground complimenting the build.

Another trip to the dyno for precision tuning of the Thundermax and this bike has new life.  The graph below shows the finished result.  This motorcycle went from 60 HP to 115 HP which is where it should be for this type of build.  Again, it is all because of the proper parts, professional installation and professional tuning.

Unfortunately, we see this often.  Customers bring us motorcycles with performance upgrades that don’t perform as well as they should.  Please reach out to us for your next upgrade.  This customer paid twice for upgrades that should have performed the first time around.  We have skilled mechanics on staff and the best dyno tuner in the country that will make your motorcycle top-notch no matter what level of performance you are looking for.

We are taking appointments now at our Fort Myers, Florida location now through April 24th.  Call Chris at 765-730-1646 for your spot in our schedule.



Factory warranty holding you back on performance upgrades on the new Milwaukee-Eights?



Some customers we talk to are hesitant about pulling the trigger on performance upgrades on the new M8 motorcycles in fear of losing their factory warranty.  Legally Harley Davidson is not allowed to void your warranty unless they can prove how the aftermarket product caused your motorcycle to fail.  Check out the Magnuson-Moss act by clicking HERE for further reading.

Not ready to go to bat with your dealer? Check out these products that you can install and enjoy the benefits of now until you are ready to go to the next level:

K&N Replacement Air Filter - K&N is known for their high air flow replacement air filters.  If there is only one upgrade that you do we recommend removing the stock paper air filter that is in your motorcycle and replacing it with a quality one.  This applies to all Harleys that are using the stock air filters.  The stock paper filter will break down over time and can get sucked into your motor and cause damage.  K&N filters are a washable, reuseable filter that can be recharged with a recharge kit.

NGK Iridium Spark Plugs – These spark plugs offer an easy and inexpensive horsepower gain. They come pre-gapped for quick install.  We have seen up to 3 horsepower on Twin Cams just with running these plugs.

Dimple Magnetic Drain Plugs – Protect your motorcycle with these magnetic plugs.  They are 100 times stronger than factory drain plugs. These magnetic drain plugs do not break down from normal or excessive engine oil.  Harley Touring Models, Softails and Dynas all have 4 drain plugs.  You can purchase one plug or buy all 4 and save when purchased as a package.  Check out our video demonstrating this product.

K&P Lifetime Oil Filter/Cooler – K&P manufacturers the best oil filters period. These filters are made from billet aluminum with a stainless steel filter insert that can be cleaned and re-used. The finned case also performs as an oil cooler that will help cool down your engine oil which will in turn, allow the oil to flow faster and keep your engine performing more efficiently.  This filter is available in three different lengths so you can choose the amount of cooling and filtration you need as well as one that fits into your budget.

Box of Lube Service Kits – We have service kits for your motorcycle that contains everything you need to perform a simple engine oil change to a complete full service.  Our kits come with your choice of Lucas Motorcycle Oil or Amsoil.  These oils will help the engine run cooler, quieter and extend your engines life.

Love Jugs Cooling Fans – Love Jugs is an external fan system that mounts to the stock horn.  They are designed to blow air across the cylinders to keep them cool.  They are very effective and you will never have to worry about overheating in traffic again.  They have several styles to choose from as well as black and chrome and are a great investment.  You power them on and off with a control switch when you need them.  If you ride in a lot of stop and go traffic then this is a great investment.  Makes a great gift also.

Ohlins Suspension – Shocks can either make a motorcycle trip most enjoyable, or they can make a trip miserable.  All Harley owners know that the stock shocks fall into the miserable category.  Ohlin’s can put the fun back into your rides.  All motorcyclists can benefit from a quality shock.  Cycle Solutions Inc. stocks several styles of Ohlin’s suspensions.  Enjoy a quality ride now while you contemplate future performance upgrades.  Quality performing shocks will also put a smile back on your passenger’s face so if you won’t do a shock upgrade for yourself, you can do it for your passenger!

All of these products are available for installation from our show truck or available online.

S&S Cycle hits the market with a brand new intake and the price is right.

New for this year is a motorcycle air intake made by S&S Cycle and it is quickly becoming one of our top sellers. This is because it is stylish and comes with a great price tag. You can purchase the entire intake assembly kit with your choice from 3 cover options for around $270.00.

S&S Cycle is a household name for any motorcycle enthusiast. Customers can purchase their products with confidence knowing it is a quality part and performs well. This motorcycle air intake has a built in stinger cone that directs air smoothly and reduces the turbulence, in which increases the air flow for more performance.

As with any air intake going on a 2008-Newer Harley that will not use the factory cover we recommend purchasing a servo cover to go on behind the new intake. The purpose of this servo cover is to hide the throttle body wires and junk that gets exposed when you take off that large bulky stock intake. The most poplar servo covers are the ones offered by Kuryakyn and Performance Machine. (add link to servo covers)
Most people are not aware of this and are often disappointed when they get their new shiny and slim intake installed and there is an eye sore behind it. We point this out during the time of install so our customers can decide if they want the cover or not.

They’re here! CSR Performance Products are now available. Let us make your motorcycle ROCK!


Cycle Solutions Inc. knows performance. We have sold and installed the top performing products for many years helping our customers get the most out of their hard earned money. We have paid attention over the years as to what works and also what is important to our customers and have created a product line called Cycle Solutions Racing (CSR) Performance Products to meet both of these criteria and then some.

Our new line of CSR exhaust headers feature a high quality ceramic coating on the inside and outside of the pipe to help keep the heat in and not on your leg! We have customers constantly seeking relief from the burning heat that is emitted from their header pipes. Our header system will easily reduce the heat and when paired with our other heat reduction products such as a ThunderMax Auto Tune and our K&P XL Lifetime Oil Filter. Heat will quickly become a distant memory. Our mechanics have installed many sets of exhausts and we understand the difficulty that some systems have when trying to do the install. We have designed our system for a fast, easy installation. Nobody wants a wrestling match when installing their new exhaust system! Performance is our middle name so of course this was a top priority when creating a system with our name on it. Our new high quality system will give you the performance gains you want and will work great with any parts combination you can throw at it!

What good is an exhaust system if you do not have a high quality air cleaner? In Sturgis, we launched our new air intake product line. The new CSR Performance Air Intakes will not disappoint. Our Intakes are made from a billet piece of aluminum, not a casting. Castings break from the vibration of the engine leaving you frustrated and having to purchase a new system. We offer them in a stage 1 or a stage 2 air filter fitment. All of our air intakes use your stock cover or you can update your look and add a stage 1 round aftermarket cover. Our motorcycle air intakes also feature a washable, reusable air filter element that lets the air in and allows your engine to breathe.

These products are now currently available on our show truck and also on our website. We have many more products in the works for our CSR product line so check back with us regularly.
