GOOD NEWS. . . . The PICTURE UPLOAD FUNCTION IS WORKING !!! The tech folks at the parent company have been able to remedy the issue. You can upload pictures once again. Thank you for your patience.
I have a 2006 Yamaha model vz250tlr and I have no spark on #'s 1 and 4 spark plugs out of 6. It runs at idle speeds and wants to surge at times. Would it be the ECU unit or the cdi box. I put new coils on it and it made no difference.
