Hi all, ever since Ive owned this 12 I had a semi loud knocking in the front end whenever I ride over rough pavement or bumps. Ive done searches over and over trying to find an answer to this problem that others have had as well. Today I pulled all the front plastics off the bike and rode around, and to my dismay the knock still exists. Ive heard it could be things like the front fairing stay, the brake pads, the ram air grill and possibly the ram air tubes. None of these things are the culprit as I removed them all. There was a poster that said there was a loose bolt under the triple tree main bolt, but I dont have anything that can crack that big main bolt, so I couldnt check that. I noticed the radiator has a fair amount of play in it on the bottom, so if I grab either side of the radiator near the bottom, while standing in front of the bike, there maybe an inch of play, not sure if thats normal but all the top bolts of the radiator are tight, cant seem to find the lower bolts. However if I hold the radiator and bounce on the bike (using a friends help) the knock is still there. So any suggestions that I missed?
