We highly recommend re-jetting your carburetor to ensure the engine runs at the correct air\/fuel ratio for peak power and reliability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this pipe compatible with the stock silencer?\u003c\/strong\u003e\u003cbr\u003e\nA: The Factory Fatty is designed to bolt onto the stock mounting points and is generally compatible with the factory silencer, though pairing it with an FMF Powercore silencer will yield the best results.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e Because these 50cc expansion chambers are made of thin-gauge steel to save weight, they are susceptible to denting. After washing your bike, coat the pipe in a light layer of WD-40 or a dedicated pipe conditioner to prevent surface rust, as the raw finish on Factory pipes is susceptible to oxidation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-50-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 50 SX Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/husqvarna-tc-50-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eHusqvarna TC 50 Performance Parts\u003c\/a\u003e\u003cbr\u003e\no    \u003ca href=\"https:\/\/motohousemx.com\/collections\/gas-gas-mc-50-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eGas Gas MC 50 Performance Parts\u003c\/a\u003e\u003c\/p\u003e\n\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
