Had my 749s for a year now first tip take off front plug cap and replace sealing it with clear silicon sealer that stops the water entry problem.
2: Check the little pin and little spring lever under the clutch lever unless this is connecting properly and depressing the pin it will cut out.
3: My clutch system needs bleeding occasionally especially in hot weather, they just seem to get air in the system.
Once all these are done you should be ok
I havn't had a bit of trouble with mine. The amber EOBD some times lights up when left idling for a time but soon disappears when you ride off possilble charging phenomenon but dosn't cause any problems.
Just ride em hard
Good luck Seb
