How to Remove Manifold Gasket on a Motorcycle

Learning how to replace the manifold on your motorcycle can save you time, money and the hassle of taking it to a professional motorcycle mechanic. This process can be done in a couple of hours, with a few tools and the right know-how. Removing the manifold gasket is part of that process.

Difficulty: Moderately Easy

Instructions

1. Secure the bike on a portable jack or lift. A lift is a more secure way, if you have access to it, because you can strap the bike down to the lift. A portable jack will work, too, though it is not as stable. You can work on the bike while it is on its kickstand, though this is not stable or recommended at all.

2. Remove all the components to gain entry to the manifold. This will include disconnecting the horn, throttle and idle cables, and removing the back plate and the carburettor. Make sure to inspect each component as it is removed for possible damage or excessive wear. Replace any parts in this condition.

3. Disconnect and remove the manifold. This will be a "Y" shaped pipe. There will be a gasket on the end of each side of the manifold. The drier the gasket, the harder it will be to remove. You need to try and peel them off, preferably in one piece, to avoid having to scrape them off.

4. Try using a gasket scraper if you have trouble peeling the gasket off. If residue is still left behind, use a die grinder or scouring pad to sand it off. Then wash it before applying a new gasket to get rid of the residue and debris left from grinding.
