Spark Plug Installation

Installing the incorrect spark plug can cause serious damage to your bike.

Spark plugs are designed to operate at an optimal operating temperature and correct tightening is critical to the operation of a spark plug. The following two major problems commonly occur if the incorrect torque is applied:

  • Excessive Tightening > Thread breakage
  • Insufficient Tightening > Overheating

Installation Instructions for new Spark Plug:

  1. Check gap on every plug prior to installation. Set gap size to engine manufacturer’s recommendation.
  2. Confirm that the thread reach of the spark plug is the right one for the engine.
  3. Remove any dirt at the gasket seat of the cylinder head.
  4. Tighten the spark plug finger tight first until the gasket reaches the cylinder head, then screw about ½ - ¾ turn more with a plug wrench. (Conical seat; about 1/16 turn more). Refer to diagrams below.
  5. If using a torque wrench, please refer to the table below.
  6. Always remove and install spark plugs when the engine is cool.

Torque is one of the most critical aspects of spark plug installation. Torque directly affects the spark plugs' ability to transfer heat out of the combustion chamber. A spark plug that is under-torqued will not be fully seated on the cylinder head, hence heat transfer will be slowed. This will tend to elevate combustion chamber temperatures to unsafe levels, and pre-ignition and detonation will usually follow. Serious engine damage is not far behind.

An over-torqued spark plug can suffer from severe stress to the Metal Shell which in turn can distort the spark plug's inner gas seals or even cause a hairline fracture to the spark plug's insulator, in either case, heat transfer can again be slowed and the above mentioned conditions can occur.

The spark plug holes must always be cleaned prior to installation, otherwise you may be torquing against dirt or debris and the spark plug may actually end up under-torqued, even though your torque wrench says otherwise. Of course, you should only install spark plugs in a cool engine, because metal expands when its hot and installation may prove difficult. Proper torque specs for both aluminium and cast iron cylinder heads are listed below.
