This is a video of our 1985 Honda 250ES Big Red. It has sat for several years in the barn at my wife's grandfather's farm. He passed about a year ago, and her mother lives there now. She wants this gone, so I recently got it running again in order to try to sell it.
The video linked below leaves little room for doubt what my question is - what's that noise?!?!? I have done an oil change and it made no difference in the sound... it sounds like a bearing, but I'm not an expert on the clutch/transmission area of motorized equipment so not really sure what exact part it is. I've done lots of research here and am very grateful for the diagrams and manuals that I've been able to get. This isn't something I think I can research my way throug, so decided to join to (a) say "thanks" to all the smart people here, and (b) ask for your help...
Without further ado, here's the video:
