Why won't my 1986 Suzuki Intruder VS 700 shift gears when it is running?

There could be several reasons why your 1986 Suzuki Intruder VS 700 is not shifting gears when it is running. Here are a few possible causes and troubleshooting steps that you can try:

1. Clutch issues: A common reason why a motorcycle may not shift gears is due to issues with the clutch. Make sure that the clutch cable is properly adjusted and that the clutch lever has the proper amount of play. If the clutch cable is worn or damaged, it may need to be replaced.
2. Transmission problems: The transmission on your motorcycle could be damaged or worn, preventing it from shifting gears properly. Check the transmission fluid level and condition, and ensure that it is at the correct level. If the fluid is dirty or burnt, it may be necessary to replace the transmission fluid or flush the system.
3. Shift linkage issues: The shift linkage on your motorcycle could be misaligned or damaged, preventing it from engaging properly. Check the shift linkage and adjust it if necessary.
4. Electrical issues: The motorcycle's electrical system could also be causing issues with shifting. Make sure that the battery is properly charged and that the connections are clean and tight.

If none of these troubleshooting steps resolve the issue, it may be necessary to take your motorcycle to a professional mechanic for further diagnosis and repair.
