I have a 2007 that was MotorTriked in 2010. I just had the clutch discs replaced as well as the spring. I hear a clicking noise similar to a baseball card positioned against the spokes of a bicycle - rat a tat tat. This noise occurs when in 2nd to 4th gear and the clutch lever is pulled in. It does not occur in neutral. It sounds like it is in the front of trike. Any thoughts would be much appreciated.
