Spark plugs how to change spark plugs xvz 1300ct

suspect Coil, check HT high tension side of spark if none then check LT low tension side you should see a spark on the points when they open if that is working then suspect coil is defective and needs replacement. also check points setting to see they are actually opening enough and are not dirty contacts.

I hope this was helpful

the socket is metric i went to walmart and got mine for 4.60

there close enough, just minor jet changes and size 34mm to 35mm

There should be one in your tool kit that came with the machine. You can purchase a replacement tool kit at the local Yamaha dealer or Ebay and it should contain what you need.

Check carburettor or fuel injecting system. Check spark plug also.

Make sure the radiator header is full. Start the engine cold, pull off #1 and #2 spark plug caps and watch where the coolant leak starts from ( if possible). Each cylinder has a plug which seals the water jacket from behind the spark plugs. These plugs are sealed by O rings and this is probably where the leak is coming from.

The air cleaner is underneath the fuel tank, above the carburetors, in a housing that basically resembles a coffin. The housing is held to the carburetors by four flexible clamps at the bottom of the carburetor joints, and the housing halves are joined by ten phillips-head screws. Remove the fuel tank, loosen the flexible clamps, remove the housing from atop the carburetors, remove the screws from the top housing, split the housing halves; the air cleaner may now be removed and replaced. Reassemble in reverse order.

The rear spark plugs may be removed with a 3/8" socket wrench, a 3"-4" extension and a 12mm spark plug socket; the front spark plugs require removal of the motor mounts, do ONLY one side at a time with the same tools you used in the rear. take extreme caution to avoid getting dirt and debris into the cylinders while removing and replacing the spark plugs. The motor mounts require an 8mm allen wrench.
