I wouldn't generalize that observation...
But there some who (obviously) neglect their motorcycle worse then a car... maybe over lack of technical insight, I don't know...
Parked outside year round, maybe even used year round, never cleaned, avoiding the costs for the standard service tasks... no TLC at all, just used... a sore sight...
IMO a weird mindset, cause vehicles do cost an arm and a leg, and the better I take care of things, the longer they will serve me and stay reliable... be it a bread-slicer or an automotive...
But it seems that many 'owners' have lost that connection, and when the neglected object breaks down/they get hit with a large workshop quota, they get frustrated and treat it disposable...
like "needing" a new phone every 3 months...
So
@leondante has now to catch up with cleansing, refurbishment and replacement tasks been omitted for years there... all at once... finding more damage as needed if the tasks would have been done in time...
By disassembling, inspecting, measuring and resealing everything he does not only build a connection with the bike, he further ensures bringing it back to the intended quality...
I envy the time he obviously has at hands, and the nerve to actually
reconstruct his building thread...
