Flip up the seat to gain access to the engine; there are two metal tabs the seat pivots on; just remove the seat to have easy access the air filter.

Remove the clips holding the air filter canister together

Now that you have access to the air filter, note the foam pre-air filter, and its "UP" notation; remove with old filter and clean air-box of any debris.

Now for the New: first insert the foam pre-filter

Now insert the new air filter into the air-box.

Replace the air filter cover, Securing retainer clips on airbox.

Now your Yamaha Golf Cart engine can breathe easier.

Replace the Fuel Filter

The fuel filter for a Yamaha Golf Cart is FIL-0014

The fuel filter is located in line between the fuel tank and the fuel pump.

If the housing is clear plastic, make sure that the fuel inside is not dark amber or discolored from age. To remove the filter, disconnect the hose from the fuel pump by using a pair of pliers to squeeze the clamp ends together and sliding the expanded clamp further down the line. Remove old filter from the hoses.

Note the fuel flow direction with your new filter; fuel flows from the tapered end toward the flat end.

Since the old filter is now off the fuel lines, tap the inlet side of the filter (the tapered end) on a paper towel-lined surface and see if any contaminants are dislodged and stain the paper towel; if so then the contaminants are a major reason for your carts sluggish performance.

Return the filter to the gas line and secure it with the clamps.

Sometimes there is a second filter located underneath the carburetor facing the front of the cart. Check to see if you have one and make sure it is also clear of deposits.

Using pliers or pinchers, squeeze the line clamps and move them close to the filter body, ensuring you get the clamp even with the fuel line at its closest to the fuel filter.

Change Spark Plug

The recommended spark plugs are manufactured by NGK, number NGK BPR4ES-sp-bp4es

Locate the spark plug(s) on the top of the engine and remove the cable, exposing the top of the plug. Use a spark plug socket and ratchet to remove the spark plug and inspect the ceramic insulator.

Now out of the engine, examine the old plug. The ceramic insulator should be ivory colored, light brown to brown would indicate the fuel mixture is too lean. If it is black in color, you might be running too rich of a fuel mixture, requiring an adjustment to the air/fuel mixture screw.

Check the gap with a spark plug gap tool (cheap or free at most parts counters) and set this gap to .028 – .030.

Replace the new plug into place with fingers; use socket for tightening after hand-threading-you neither wish to cross-thread the plug, nor break the plug, or strip the threads in the head. Once tight, check the plug-wires for fit and any cracking or damage.
