@@charlesfriend9557 It's what most if not all customers want and that's why we mostly have only mechanics left that are parts replacing monkeys. Who is willing in this day and age to throw a lot of money into old bikes and restore them and maybe even improve them when you can get way better and newer bikes for less? Also not every workshop has the tools shown in this video let alone someone who is skilled enough to use them to full effect. It's mostly service jobs these days. New tyres, new brake pads, new brake discs and oil/filter changes. Anything else requires a lot more effort, time and money that only a few customers are willing to spend. And those customers are going to very special workshops that are truly few and far between. Most of the really expensive work is done under warranty which is free for the customer. For getting most out of new 4-stroke bikes which are EFI, you need a dyno and most of the workshops just don't have that. So, that will leave you with service jobs and parts replacements. And even that is fucked up by workshops because the pay is low and the work ethic of mechanics is low. I live in Germany and bike mechanics here are earning minimum wage or slightly above. Only really good and big workshops with only a few left are paying well.
