Part: Spark plugs

Video tutorial

This brief guide provides instructions on how to remove and replace the spark plugs on a Benelli TNT 300 motorcycle. First, place the motorcycle on a stand and begin by removing the rider's seat and the fuel tank, unscrewing the fastening screws and disconnecting the fuel line; then disconnect the coil connectors, unscrewing the two spark plugs from the cylinder head with a socket spanner, as shown in the video.

At this point, install the new spark plugs, hand-tightening them before securing with a spanner; reconnect the connectors and reattach the fuel tank, then start the engine!

Oil Change for Royal Enfield Interceptor 650

Learn how to change the oil on the Royal Enfield Interceptor 650: first, remove the oil filler cap; then, go under the bike and remove the plug from the sump, collecting the used oil in a suitable container. Dispose of it at an authorised centre. Replace the gasket on the sump plug for added safety. Change the filter; this will also leak some oil; let it drain into the same container where you collected the engine oil. A 4-litre kit of synthetic oil SAE 10w40 and the filter costs £53.48 on Amazon, with free delivery. The gasket for the plug is also available separately, but for £0.18 for the gasket, they charge £9.95 for shipping on Auto-Doc, making it more economical to buy the kit with both plugs, lower and upper, each with its gasket, which costs £7.69 on Amazon, with free delivery. After refitting the plug and the filter, top up the oil using a funnel and close the cap. Job done.
