Question about 1981 Suzuki GS 750 L

1 Answer

I have a simular problem to (By ithacaautomo on Jun 28, 2009) with my 1982 Suzuki GS750e. Except the bike runs worse as it warms up. I've cleaned the carburators and they didn't look bad to start with. When it runs, it's not runing on all cylinders but the plugs are getting spark so my assumption is that I still have a fuel problem. I never came across a fuel filter. Where is the fuel filter?

See which plugs are running good (cream to light brown) color look at the other carbs. make sure you have no cracked rubber or flat o- rings or other vacuum leaks. You will need vacuum syncronizer or a set of good vacuum gauges to balance the carbs properly. If there is a filter it will be between the tank and the carbs. you might want to pull the valve and screen out of the gas tank, and make sure everything is clean and in good shape.

1986 Suzuki Savage loosing acceleration

I have been having a simular problem with my girlfriends bike.She complained about the bike looseing power or "bucking " as she calls it , at speed.Several "shops" have played around with it ,but none have solved the problem .She feels the bike is not worth spending any more money on ,so I have tackled it .
The first thing I found was that someone had put the wrong hose on the pet ****. To open the pet **** you need vaccum from the cylinder side of the carb. There are two other hose nipples on the filter side of the carb that I don't know where they go .If you know , please tell me .The vaccum helped but didn't solve the problem.So I took the carb apart , cleaned out all the jets . One was pluged.
Now I have to run the bike a little,then check the spark plug. I think I am getting close.

Cant tell what year

The 10th digit in the VIN denotes what the year of the bike is. (as long as it is a 1981 to present) * Beginning in August 1964 - 1980 a system went into effect that included vehicle model and year within the production serial number. This system defined the first two digits to indicate the model, the third digit indicates the year, with the fourth through tenth digits now defining the actual serial number. If you call GDL Cycles they can help you. 1-888-707-2787 they also have a service manual available for the Suzuki GS750
