Question about 1991 Yamaha FZR 600
If old gas sat in the carb.s for more than a month it starts to dry up. As it drys up it leaves behind a varnish like film that stops up some very small ports and pin holes inside a motorcycle carburetor. It is also very hard to get out. You can try this before you pull the carb.s for a full cleaning. Use a product called Seafoam, get as much gas out of the carb.s as you can. use a turkey baster and force the seafoam into your carb.s fuel line that you took loose from the fuel tank. Let that set for days 1 or 2. then hook up the fuel tank with a mix of good gas and seafoam, (not a lot but enough to start it up. Move the cycle outside as the seafoam will make a lot of smoke if it does start up. If that does not clear up the problem you may have to pull the carb.s and remove the blows to clean the inside. If you have to do that do not DO NOT MESS with any adjustment screws, DO NoT MeSs with any screws. Just take the carb. bowls off keep each one separate and number them so they do not get mixed up. do not mix up any internal parts. It is best to work on one at the time so nothing goes wrong. Work on a large sheet so if you drop a small part you can find it, you do not want to be missing some tiny spring or screw. Hope this Helps.
