Any idea what would cause my cruise to start surging while traveling down the road around 75 mph? By surging I mean sudden bump in speed, followed by sudden drop, then sudden bump in speed again -- not gradual. Tried it two or three times and it did the same thing. Finally pulled off and got gas, then back on the road. Seemed to do okay but I didn't ride long after that. Reckon it's something like a needing to check cable lash? Any ideas would be appreciated.

Try this proceedure

The engine should be at normal operating temperature and throttle and idle cables should be correctly adjusted. To set the correct cable lash proceed as follows:

1. Push the Cruise Switch on the right handlebar to RESUME and hold it.
2. Turn the Cruise ON/OFF switch to ON.
3. Turn the Ignition switch to IGNITION.
4. Start the engine. The green Cruise Enabled/Engaged lamp in the speedometer will illuminate.
Wait 3 Seconds for the lamp to go off.
5. Release the Cruise Switch from the RESUME position
6. Push the Cruise switch to RESUME and hold. Cruise will pull in cable until change in RPM is detected. The number of motor steps required to rev the engine is stored in memory.
7. After engine revs and Cruise Enabled/Engaged lamp is extinguished release the Cruise Switch from the RESUME position.
8 Turn the ignition switch to off.
