How To Rebuild a Motorcycle Carburetor - Yamaha TW200 Carb Clean and Rebuild DIY

[@KSLoneWolf1776]

The screws on the TW and many other Japanese motorcycles are not standard US Phillips screws, they are JIS (Japanese Industry Standard) screws. That is why they strip out so easily;

Thanks, I had no idea. They're definitely a very soft metal...

My oil in my crankcase has filled completely with fuel. Ive read that this means the carburator needs cleaned and rebuilt. Sound right? Thanks

Bummer! It's possible that the little carburetor float plunger is dirty or damaged and doesn't shut off the flow of gas when the bowl fills up. If the overflow is also clogged up the gas will flow down with gravity and can end up inside the engine. When you rebuild it, pay special attention to the float plunger and also make sure all the little holes (even the ones that don't seem like they may do much) are completely clean. A high-E guitar string works really well if you don't have the cleaning tool. Good luck!

Why did you rebuild this carb? Was the bike not running properly? If so, can you explain the symptoms and did this rebuilt resolve the problems?

I picked up the bike at auction and it wasn't running, so as with any carb the first step was to clean or rebuild. When I opened up the carb I saw the gaskets were in bad shape so I just got the rebuild kit. In general, carburetors tend to be picky so if the bike isn't running well one of the first steps is to clean it out, especially if it's been sitting for a while. It's also a good idea to run them dry when you don't plan to ride it for a few days (start the bike , then turn off the fuel valve and just let it run out of gas). This will keep things from clogging up...
