'93 Vulcan 750, 23,000 miles. This only occurs when road is wet. I can ride maybe 20 miles or so and all of a sudden the bike will cut right off. When I try to restart, it is difficult to restart and takes several tries, to the poinbt of almost running the battery down. I am thinking an electrical connection is getting hit with road spray but not sure where to start troubleshooting. Other than that it runs great. Any suggestions?
