What is the difference between a bolt-on and a full big bore kit for a Twin Cam 88?
When it comes to upgrading the performance of a Harley-Davidson Twin Cam 88 engine, there are two common approaches: bolt-on kits and full big bore kits. Bolt-on kits typically include components that can be installed without modifying the engine case, such as high-flow air filters, exhaust systems, and performance cams. These upgrades can provide a noticeable improvement in power and torque, but they are limited by the stock engine displacement of 88 cubic inches.
On the other hand, a full big bore kit involves replacing the stock cylinders and pistons with larger ones, increasing the engine displacement to 95, 96, or even 103 cubic inches. This requires machining the engine case to accommodate the larger cylinders, as well as replacing other components like the camshaft and fuel system to optimize performance for the increased displacement.
While bolt-on kits are generally less expensive and easier to install, a full big bore kit can provide a much larger increase in power and torque. However, it also requires more time, money, and expertise to install properly. Ultimately, the choice between a bolt-on kit and a full big bore kit depends on the rider's budget, goals, and mechanical skills.
What is the recommended size for a big bore kit on a Twin Cam 88?
The recommended size for a big bore kit on a Twin Cam 88 can vary depending on the specific application and intended use. However, a popular option for increasing the displacement of a Twin Cam 88 engine is to install a 95 cubic inch kit. This involves boring out the cylinders to 3.875 inches and using larger pistons and rings. This can result in a significant increase in horsepower and torque, as well as improved throttle response and overall performance. It is important to note that installing a big bore kit may require additional modifications such as upgraded camshafts, fueling components, and exhaust systems to fully realize the potential gains. It is always recommended to consult with a trusted mechanic or performance specialist to determine the best options for your specific needs and goals.
Will I need to upgrade other components when installing a big bore kit on a Twin Cam 88?
When installing a big bore kit on a Twin Cam 88, it is highly recommended that you upgrade other components as well. The increased power and torque output of the bigger engine can put a strain on the stock components, which can lead to premature wear and potentially catastrophic failure.
Some of the components that you may want to consider upgrading include the fuel injectors, air intake, exhaust system, clutch, and transmission. You may also want to upgrade the engine management system to ensure that it can handle the increased power output.
Keep in mind that the specific upgrades you will need may vary depending on the size of the big bore kit you install and the intended use of your bike. It's always a good idea to consult with a professional mechanic or performance shop to determine what upgrades are necessary for your specific situation.
