How to Dismantle the Engine of the Sym GTS 125?

Model: Sym Gts 125
Part: Engine

Video tutorial

To dismantle the engine of the Sym GTS 125, you must completely remove the engine from its housing: to do this, you will need to take off the components that hold it in place, such as the underseat compartment and the surrounding fairings. Once the engine is extracted from its housing, you can proceed to unscrew the bolts that secure the cylinder at the top, completely removing it and locating the piston underneath.

This piston must be detached from the connecting rod by loosening the retaining ring, which will then give access to the further components underneath.

How to Change the Engine Oil of a Harley Davidson Sportster

Changing the engine oil of a Harley Davidson Sportster requires a few simple operations performed with care. Start by positioning the bike securely, preferably using a centre stand or suitable support. Locate the oil drain plug under the engine and place a container to collect the used fluid. After removing the plug, allow the oil to drain completely, waiting a few minutes for all the fluid to be expelled. Once emptied, reinsert the plug and ensure it is tightly screwed in. At this point, locate the oil filler cap, unscrew it, and pour in the recommended quantity and type of oil as specified by the manufacturer. Check the level using the dipstick or built-in indicator, adjusting the quantity if necessary. After finishing, briefly start the engine to allow the oil to circulate, then check the level again to ensure it is correct.
