Idle problem
SOURCE: bike runs at Idle but dies when given gas
have you changed the fuel filter? you are not getting enough gas, are jets squeaky clean? there is a good fuel system cleaner in the USA called Berrymans B12. put some in the tank warm up bike then let it stand overnight and see what happens. if still no luck repeat process. if you still have same problem then get new fuel filter
good luck
SOURCE: Hi I have a 1985 Yamaha xs 650.It is back firing
There are several reasons for backfiring, your sounds like either a faulty spark plug or coil. Another thing to check is the Carby Float Level on the Left Cylinder. This might sound a little funny but if you haven't rebuilt the topend of the engine I would look at a slightly colder spark plug not hotter. When fitting new plugs, check the gap but it should be OK from the manufacturer. Please resist closing the gap by banging it on a hard surface, it can fracture the new plug and you will be back where you started.
