An engine is still 'just an engine'. Pretty much, same moving parts their has allways been since the first one...
Obviously, their are special advances made along the way, new materials, new designs/concepts. New ways of installing parts or have them work. But out of all the cars and bikes ive worked on over the years, the differences are minor. Their is still a Piston, Crank and Valves in them all.
You tube however, IS A GOD-SEND for mending stuff!!
Just for those times you get a weird thing happening or just need a re-fresher b4 a job, someones done a Vid. (or yet to..)
So i say, DO YOUR OWN WORK, even if its just the simple Oil changes/Valve adjust/Tune-up/Fork Seals/Etc., it'll save you money.
When i buy a bike, i make it a point to buy a workshop manual for it too.
The way i see it is this - Mechanic work, Eg Service+Tune=$500(ish)
Avg. wage p/day = $200
So next time you get it serviced, you have to work 2.5days to pay for it. BUT, if YOU did it, it might take you half to 3quarts of a day. But then youve got the arvo off, maybe go for a Ride perhaps...??
My first job was working with my brother, at a Classic Car workshop. Only started sweeping & servicing, but did get a chance to do bigger jobs, on a few Nice cars eventually.
So i might've got an early heads-up on mechanical stuff, but its something that can be learnt from the basics, so no excuses really.
Since then ive either assisted or done the work myself. Cant imagine how much ive saved, but even a little is a lot...?
I have to admit tho, the older i get, the more i get someone else to work on my HEAVY 4wd tho!! lol
My 2c. (more like 'My $20 worth'?)
