Long job there, but they usually are. Going to be very nice when finished.
Bet that £600 has become a bit more by now..
As I say to the wife, its not the money, its the joy that I get doing the bike. think think

Not convinced she agrees though.

I do like the feeling when you've you've got your teeth into a project bike especially once your over the hill and its (hopefully) all coasting home as you must be now Thumbs Up

Don't know if/when I'll get the urge to do another bike myself partly as always seem to have other stuff to do (mostly on the PC lol) but there's not a lot out there these days for <£1000 that floats my boat Sad

Hydraulic tappets? Never heard of them on a bike before and tbh not really sure how they work compared to a bucket/shim setup although can the cams look shrouded in extra covers so guess oil under pressure is involved think

/wanders off to youtube to learn about Hydraulic tappets Grin

One good thing about them is their self adjusting Thumbs Up

Honda was pretty hot on them during the 80's: they were marketed as part of Honda's effort to reduce running costs on the long run.
I still remember the PC800 advertisement where it was amply advertised the bike had "self-adjusting" hydraulic tappets: remember those were still the years when you had to check valve clearance every 7,500 miles on many bikes.

If you ask why they failed to catch on, two reasons.
First, manufacturing the engine head is considerably more complicated and expensive.
Second, they cause valve "flutter" over 7,000/8,000rpm. It won't affect reliability, but it makes squeezing extra power and torque so much harder.

Besides, with far increased precision in machining valvetrain components and far better steel used in valve springs there really isn't much reason for them anymore. Kinda like Desmo.

good explanation Thumbs Up

I watched a few videos and learnt a bit but as you say, the losses (power, cost & weight) do seem to outweigh the gains at least on bikes
