Hi Fellas (and lasses so I don't offend )

Just here to introduce myself. Had a GS for years now and a sports bike. This is two dream bikes rolled into one.
Loving it so far.
Only issue is I have been to the dealers because of a clucking noise when going over sharp bumps/ cracks in the roads. Dealer not a lot of help. Feels like stand knocking but took a ride with both cable tied which made no difference. I now think it may be chain slap but its is on the tighter side of adjustments done by the dealer to try to sort the issue. Anyone else had this?
