Generic Comment:

My guess is that a 1980 is points. Look in the area where the cam shaft should be.. Look for a round or oval cover with phillips screws. Pop it off.

Year of manufacture of Johnson 40Hp outboard Model No AJ40BALE1A Serial No. G02651879

Near as I can tell, it's a 1979. As of 1980, Johnson/Evinrude used two LETTERS at the end of the model number to designate the year. (See attached) Your model number ends in a number and letter (1A) which leads me to believe it's earlier than 1980. Prior to 1980, the last two numbers of the serial number were the year. That's how I surmised yours is a 1979, by the last two of the serial. G02651879

Hope this helps.

Ignition plate coverd with carbon deposits @100 miles, must clean them with eraser or engine misfires, won't start. Cause & remedy? Thanks!

I believe that the 1980 Xs650 still used points and condensers for ignition. I know that my 1979 did. I would check to see if you had a bad condenser. That can mess up the way that points are firing and can cause excessive carbon build-up. I'm not sure if the condensers are sold separately from a points set, but you can always buy a matched set and only install the condensers so you don't have to reset your points gap.
It might also be worth checking the voltage coming into the points assembly. These Yamahas are known for bad ground points, which can spike or drop voltage at points in the electrical harness. You might be getting odd output from the rectifier, which could be due to a bad rectifier or simply bad wiring connections. But my immediate inclination is to test or simply replace the points condenser(s).

Hi , Can you tell me why a xs650 yamaha has three cylinder head valve covers with three 6mm studs and one with four 8mm studs ? Regards John Hall.

My bet is the 8mm studs also serve some other purpose, and therefore needed to be able to apply more force, evenly....Something below is the issue, and not likely the valve cover.

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
