Just wondering if anyone out there has had this problem. I have a grinding sound when started cold lets up as it gets warmer but is always there. Took it to my nearest Honda dealer "where" I bought it and he said it was transmission spline noise and common on some Goldwings. Had a reg 2012 Goldwing with 43,000 miles and not near as noisey as this 2010 trike with 16,000 mile. Bike shifts great and runs great just not real happy with the noise. Any ideas. Thanks in Advance.
