Motorcycles are high-compression, high-revving engines that typically do not last as long as automobile engines. You can expect to rebuild your motorcycle's engine at about 100,000 miles or less, depending on the size of the engine. For a top-end overhaul, you would remove the cylinder head and replace the pistons, rods and rings.
Procedures:
1. Remove the four bolts that secure the rocker cover to the top of the cylinder head. In some cases, the bolts require a 16-point socket. This is common in Harley-Davidson Evolution engines. Most other motors will require a standard hex-head socket. Pull the rocker cover off of the valve box.
2. Remove the four nuts that secure the valve box to the cylinder head with a socket and ratchet. Pull the valve box off of the cylinder head.
3. Remove the two bolts on the cylinder head that secure the intake manifold. This typically requires a hex-head socket, but in some cases, the heads on the bolts might require an Allen wrench.
4. Pull straight up on the cylinder head to remove it from the crankcase.

Check the Brake Master Cylinder
The brake master cylinder plays a crucial role in a vehicle's stopping ability. The master cylinder is where brake fluid is stored, and brake fluid helps activate the brakes When the master cylinder begins to fail it will cause the brake pedal to feel squishy. This could lead to a failure in the brake system. Check the brake master cylinder at least once every three months for damage, wear and brake fluid level.
Procedure:
1. Clean the outside of the master cylinder with a lint-free rag. You can find the location of the master cylinder in the vehicle's owner's manual, but it is typically located in the engine compartment near the driver's side. If there is a residue of grease on the master cylinder, put some degreaser on the rag and wipe the master cylinder clean with it. Do not put the degreaser on the master cylinder directly to avoid contaminating the brake fluid.
2. Inspect the exterior of the master cylinder for leaks, cracks or holes. Pay close attention to where the hoses attach and inspect the ends of the brake lines for cracking and wear.
3. Pull the cap off of the master cylinder and clean it thoroughly with a rag. Check the level of the brake fluid. Most master cylinders will have an indicator on the side of the cylinder that marks where the fluid should reach. If there is no indicator, the fluid should be about 1/2-inch from the top of the cylinder.
4. Replace the missing brake fluid. Consult the owner's manual for instructions on what kind of brake fluid is required for the vehicle. Read More »»
