Best Big Bore Kit For Twin Cam 88 Reviewed
In the past when Harley-Davidson bikes were designed with the Twin Cam 88 for the first time in 1999, they had over-built cases and flywheels to increase horsepower and support torque. Today, however, these bikes have oversized pistons, cams, and heads that can be installed at the same time when the new engine was first introduced.
Simply speaking, a big bore kit will offer a significant upgrade to the performance of your bike. It replaces the cylinder bore and the stock piston with a larger version; this provides a lot of torque, increased combustion flow, and extra displacement. The kit will also make the size of the engine bigger.
Once you have installed the kit and made all the necessary and correct upgrades and modifications, you will feel the larger cylinder and bore with a single twist of the throttle. The bigger the bore, the better will be the throttle response.
If you are looking for the best big bore kit for the Twin Cam 88, you can consider the following suggestions:
When it comes to bore kits, S&S Cycles kit has always believed that bigger is better. This is the main idea behind the company’s 98-inch silver big bore kits. While its predecessor (the 97” variant) has been around for some time, the 98” kit is much bigger. Apart from the additional displacement (one cubic inch), the new 98” is also better for a lot of different reasons.
One of the best reasons to buy the S&S Cycle kit is the larger pistons. These pistons are made by CP Pistons. They can effectively increase the compressions, thanks to the 10-CC pop-up domes. The company has also increased the squeeze a bit because they believe that the performance cams will work better with more compression.
The pistons are fitted with another nice feature – they can be installed and used in the stock cylinders bored out for the appropriate size; alternatively, it will also save you quite some money.
If you are looking to increase the horsepower of your Harley-Davidson (1999-2006 models) motor, you can choose this S&S 95” big bore kit. Installing this kit is easier than your routine top-end job. The kit contains everything ranging from the required gaskets, 585G gear drive cams, and high-performance tappets to pushrod covers, adjustable pushrods, pistons and cylinders, and super stocked cylinder heads.
When fitted with stock cylinder heads, this big bore kit will provide you with the results that you are looking for. The kit will expand the displacement of your Twin Cam without adjusting the stroke. You will be able to maintain a standard displacement while retaining the previous crankshaft.
For better cooling, the cylinders have more cooling fin area and have already been drilled and holed so that you can install it immediately. It comes with a black powder-coated finish to prevent rusting.
The 97” big bore kit by S&S is a top-notched choice if you are looking for something to pair with the stock cylinder heads. It is the largest bore (3.9”) that can be used in a cylinder safely. This bore kit has received a lot of positive reviews from seasoned bikers, singing praises about the easy installation process and its durability.
While the stock cylinders can be fitted into the pistons, the cylinders included by S&S feature cast iron liner, which adds more power. The kit includes the cylinders, top-end gaskets, and piston setup. You also do not have to think about the flywheel rebounding.
You do not have to install the crankcase machining, which makes the installation process a lot easier. The pistons are coated and forged for durability and will last for a long time to come. They are also compatible with 89CC stock heads.
Should you buy a big bore kit?
You can opt to buy a big bore kit if you have grown bored with your current riding setup and looking for a change. You will see immediate results and set a new bar of success when you are testing your ability on your bike, only after you have made all the other appropriate changes.

Overall, a big bore kit will increase the power of your bike. However, if you are fine with the current setup, installing this kit is not necessary.
Big bore kits will improve the performance of your bike. However, it is important that you install it correctly, lest you meet with an accident. Therefore, it is recommended that you get the installation job done via technicians and experts.
