I have 2 customers that i know of that there units starter solenoid clicks but engages the ring gear intermittently when one keeps turning start switch to crank the engine to start and run. even with new starter and new ignition switch battery is new and connections are good. my thoughts are that the starter drive is not messing the flywheel ring gear properly as both gears look good. as i feel the started drive gear is not engaging but is being stopped by the gears not going into gear until its bumped just few times or turned till it messes and then it cranks the engine an starts. this is a intermittent issue the solenoid clicks but starter does not run until the drive engages . I have searched this issue all over and have not found any results i know i cant be the only one with this issue . i have thought of machining the starter drive gear bevel a bit to see if this solves the issue. As i thought more research maybe done and see if there is a fix for this issue thanks everyone for any help or ideas as I still wait for Kawasaki tech support to respond to my requests as calling on the phone during work hours has resulted in long waits on hold and work must come first. That's why I am here on my own time at home researching this issue to solve for the customer and learn how to fix this issue ..
