Installation tips:
Remove terminal nut before installing new spark plugs. Its screwed onto the top of the spark plug.
Put a light coating of anti-seize on the spark plug threading before installing. After all, youre threading a steel part into a aluminum engine case.
Dont over tighten the spark plug, 1/8 to 1/4 turn past finger tight.
When using the old spark plug wires, trim them back 1/4" - 1/2" to expose fresh wire, then using a pick type tool, fan out the wires before threading on the new resistor cover.
Twist on the new cover about 3 full turns and give it a tug to make sure its snug.
Also fits tons of other bikes. Check the part number and photo to see if its what you need.
