depends on what plugs, some are not gap settable.
usa spec, 2010.
read this FSM page.
hen servicing an iridium spark plug, do not touch the center electrode. The center electrode on this type of spark plug is slender and can be damaged if a mechanical force is applied. Do not clean or adjust the gap for the iridium spark plugs.
IF NOT THAT THEN,
old technology spark plugs, not above.

Turn the ignition and start the Suzuki Eiger. If the engine has difficulty starting or will not start at all, there may be a problem in the electrical or starting system. Remove the spark plug wire from the spark plug and remove the spark plug from the engine using a spark plug wrench. You can replace the spark plug or use a wire brush and gap tool to clean and re-gap the spark plug. Insert and tighten the spark plug, reattach the spark plug wire and try to restart the engine. Remove the battery cables from the battery and attach a battery meter to the battery. Observe the amount of charge the battery is holding and if the meter has a test feature, test the battery to see if it will dispense the correct amount of power. Clean the battery contacts with a wire brush and reconnect the battery cables. Check the oil, gas, transmission and brake fluid levels on the Suzuki Eiger. If there is not enough gas in the ATV, it will not start. Checking the fluids regularly to see if there are any leaks or if any of the fluids are dangerously low. Top up any fluids that may be low before you use the ATV. Adjust the fuel idle mixture screw on the Suzuki Eiger's carburetor if the engine is running rough. Inspect the air intake and exhaust pipe for the Suzuki Eiger. Any blockage in or on these components can affect engine performance. OBD2 PROMOTION FindOBD2 com

I by some new Spark Plug, i would like know how to adjust the sprek plug gap
1995 Suzuki vitara

gap is 0.039-0.043 [in] ngk bkr6e-11

there is a white label under the hood called emission label, on that label it will have spark plug gap

You remove the rectangular plastic cover on top of the engine(2 screws), under that is the plug wires and spark plugs. Pull wires straight up, remove plugs with proper spark plug socket, extension and ratchet, reverse to install.

Platinum plugs are not required but will allow longer change intervals. Check the gap but do not gap them, if they are not properly gapped. Bring them back and asked for new ones.

The metal's on the Platium plugs are harder then copper plugs and can break upon trying or break in your cylinder when in uses.

Good luck and hope this helps
