My take from the forums and experience would be some true but mostly not. First, limited production before 2002 and the 2nd gen redesign came leaves a 4yr engine and a lot of bit pcs behind. Bike pick and pull, old OEM shelves and ebay or commercial equivalents I think filled about everyone's request except for something like a new rack or seat. 2002-2006 looks pretty well covered minus that TB boot that goes to the cans. I know chasing that has sucked for 2 riders. As for after market? Well heck that's what we look for today right?
Longest wait I have had on my 04TC was the OD pulley. Front TS were coming apart and went for modding them vs OEM. There might be some specifics out there but I doubt in any qty that would stop anyone wanting a good dependable ride that doesn't break the bank just to get it in the garage. I may still own a HD one day but my main ride will always be a VIC!
