Instead of buying a top-end set now and a bottom-end set later, you get the gaskets and seals for the whole engine in one pack, so you can split the cases, rebuild and close everything up with fresh gaskets. Easy Life Markets sells the kit as a single set, and the product photos show every piece laid out so you can match them against your engine.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003ca href=\"https:\/\/en.wikipedia.org\/wiki\/Yamaha_YZ125\" target=\"_blank\" rel=\"noopener\"\u003eYamaha YZ125\u003c\/a\u003e is a two-stroke motocross bike that Yamaha has built for decades.

It is fine for a quick piston swap. A full gasket kit goes further and includes the crankcase gasket and the side cover gaskets, which you need as soon as you split the cases or open the clutch or ignition side. If you are rebuilding the bottom end, replacing crank bearings or tracking down a leak from one of the covers, a full kit is the one to buy. It is also simpler than ordering individual gaskets one by one.\u003c\/p\u003e\n\n\u003ch2\u003eParts Worth Checking While the Engine Is Apart\u003c\/h2\u003e\n\u003cp\u003eWith the engine stripped, it is a good time to inspect the parts that are hard to reach otherwise. Check the crankshaft seals and main bearings for play or roughness, look at the reed valve petals for chips or cracks, and measure the piston and cylinder if the top end is coming off. Inspect the clutch plates and springs while the clutch cover is off, and check the water pump shaft and seal for any sign of coolant leaking into the oil. Catching a worn part now saves you from pulling the engine apart again a few rides later.\u003c\/p\u003e\n\n\u003ch2\u003eTips for a Leak-Free Rebuild\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRemove every trace of the old gasket from both surfaces.
