It has a timing chain.
you cannot adjust the ignition timing on this car. a manual will help if you need to set cam timing
This is the amount of time that it takes the ignition to start. This information would be present in the users manual.
Not all 4.3 engines have adjustable ignition timing. Some have crank-fire ignition; timing is entirely controlled by the onboard computer. Thus there is no user adjustable timing. Check a Haynes or Chilton manual. If you do have adjustable timing, be very careful about a specific sequence required to set the timing. Once again, check a manual.
Typically timing specifications are listed in "degrees before top dead center", however, on some very high compression engines those specifications may be different. Check a shop manual for the specifications for YOUR engine.
Base ignition timing is 5 degrees advanced +/- 1 degree. I've attached some links below for additional information.
The ignition timing is non-adjustable. It is strickly electronic, and you cannot change it. The valve timing is controlled by the timing belt. If it has jumped time, you have to remove the timing cover to access the belt, replace it, and set it to the correct specifications.
Get a chiltons repair manual from the library for your car.
there are different types of timing, cam/ignition. get yourself a haynes manual. www.honda-tech.com is your friend.
The GS 650 has fully transistorized ignition system. I have a 1982 GS 650 G with the original Suzuki service manual. There are several bullets in the manual highlighting the features/benefits of this system. The bullet of interest to you is the following one which I quote from the manual: "*Ignition timing is maintained properly at all times and requires no maintenance." My Norton driving neighbor says there must be a way to adjust the timing and that I just haven't found it. Not so- these bikes do not need timing adjustments.
