What does a Stage 2 kit do for a Harley?

A Stage 2 performance upgrade is a cam change upgrade. In any engine, the cam drives the valves and the valves open to allow air in for combustion.

How many cc is a twin cam 88?

1,450 cc

The 88 represents the displacement in cubic inches of the standard engine. The bore is 3.75 in (95 mm) and the stroke is 4.00 in (102 mm), meaning the displacement is 88 cu in (1,450 cc).

Does a bigger bore mean more compression?

All of these components have a direct affect on compression. For example, as the bore becomes larger, compression increases. If you use heads with a smaller combustion chamber, the compression will increase. Even changing to a thinner head gasket will increase the compression ratio.

What does a big bore kit do?

They replace your stock Original Equipment Manufacturer (OEM) parts and increase horsepower and torque by increasing the engine size (displacement). Some big bore kits will also include other items like bigger carburetors, performance camshafts, and big valve cylinder heads to deliver additional power and performance.

How much horsepower does an 88 cubic inch Harley engine have?

Harley-Davidson Engine HP Chart

What is the best bore to stroke ratio?

Rod Ratio: The Math
We hear a lot of engine builders shoot for a ratio between 1.5:1 and 1.8:1 on a street motor, with 1.75:1 considered ideal, regardless of application. The most highly developed four-stroke engines in the world – Formula 1 and motorcycle engines – have rod ratios of more than 2:1.

What happens if compression ratio is too high?

Higher compression ratios can make gasoline (petrol) engines subject to engine knocking (also known as “detonation”, “pre-ignition” or “pinging”) if lower octane-rated fuel is used. This can reduce efficiency or damage the engine if knock sensors are not present to modify the ignition timing.
