This is a simple video demonstrating the best method to detect vacuum leaks around your carb boots. Vacuum leaks are a fairly common problem in older bikes, and luckily they can usually be remedied quickly and easily, the first step however is diagnosis. If your bike is running rough, won't rev up or has an irregular idle, before you take off the carbs and open them up, check for vacuum leaks. A vacuum leak occurs when too much air is introduced into the combustion chamber via a failure in one or more of the carburetor boots or other rubber mating surface. When too much air is sucked in, then the bike cannot combust the gasoline efficiently; there must be an optimal ratio. Therefore it is up to you to detect these leaks, and either plug them up or replace the carb boots. In this particular bike, the engine was running VERY lean. Not only did we have vacuum leaks, but the baffles were taken out of the engine, and the previous owner had removed the air filter and neglected to install a new one. This is not only dangerous by allowing foreign material to enter the engine, but it also makes the engine run much hotter, as lean explosions create more heat than regular ones (think about blowing on a fire in your fire place: more air, hotter fire). This can be detrimental to a variety of parts in the engine, and it is a good thing we didn't ride this bike around too much before finding the problem. If anyone has any questions as to why this is important or how to find/repair these ...

Motorcycle Repair: How to Clean a Motorcycle Carburetor

Motorcycle Repair: How to Clean a Motorcycle Carburetor Video Clips. Duration : 22.90 Mins.
**Always follow the instructions in your repair manual when doing repair or maintenance work on a motorcycle. Manuals can be found at the dealer and online.** Almost all motorcycle carburetors are slide type carburetors. Slide carburetors can be further broken down to either mechanical or vacuum operated. The vacuum operated carburetors are called CV or constant velocity carburetors. The slides in a mechanical carburetor are operated by the throttle cable and the slides in a CV carburetor are operated by engine vacuum. Both type carburetors are very similar and are cleaned the same way. Although care must be taken with the rubber slide diagram in a CV carburetor. If you choose to clean a carburetor with carburetor cleaner from a can, or chemical cleaner in a dunk tank or gallon container, you must remove all rubber and plastic pieces on the carburetor, or you risk ruining the parts. A parts diagram for your carburetor will help you identify all the parts that make up the carburetor, so you can remove the plastic and rubber components before exposing the carburetor to chemical cleaner. Another method of cleaning a carburetor that doesn't involve toxic cleaners and is safe to use on all parts of the carburetor is a ultra sonic cleaner. Ultra sonic cleaners are usually marketed as jewelry cleaners, but they also work great for cleaning carburetors. Carburetors have passage ways in the body of the carburetor. Some passage ways are used as vents and some passages are used for ...
