gaz consumption

[Anonymous]

Hi !

I have a problem with the gaz ,with a full tank of suprem gaz (89,9 l)

I can only make 130 km !!! (gs 1150 1984)

so my brother and I we swap the carb to do some test and I think nothing change.

My exhaust smell gaz very well .

during the change we look in the motor by the carb entry and we have notice that my brother engine was very clean inside(almost white)
and mine was very black .



Is my problem can be the black inside the motor ???


excuse for my english

Check your shims especially on the inlet side. I would have expected it to be a problem with your carbs but as you have checked these I would look to your shims.

Make sure that the engine running on all four cylinders.

Where all the four inlets black?
