Hi to all-I'm a newbie here-great forum! '03 road king w/13,700 mi. I have a grinding noise & vibration coming from the primary. It happens when bike is cold in neutral with clutch in or out idling but once clutch is in and in gear its less or not at all. Also when warmed up in neutral with clutch out. I can also hear it a little down shifting into 2nd and alot more to 1st (not heavy down shifting either). Also cold in neutral I can roll the bike and it will go away at certain spots. Fresh HD+ in tranny & primary, chain adjustment looks good, adjuster shoe worn about 1/16", belt tension is good also-I also tried loosening it just a bit with no help. Clutch is also adjusted with no real signs of slippage. The bike shifts and finds neutral great. Been reading the HD bible trying to wrap my brain around clutch packs, compensating sprockets & transmissions!!! Any ideas or help welcome!!!!!!!
