A tappet mystery
Athame57:
Is there an error in the Honda manual? I've attached an image of the page, it says and illustrates to turn the crankshaft clockwise, yet everywhere else on the internet seems to be saying counter-clockwise , which is it to be? It says the first adjustments should be cylinder one, both of them, but the inlet tappet is sitting far higher then the exhaust, I thought these things needed to be in their high position to be adjusted? I've got to relearn what I had no trouble with on past twins ...sorry if I'm starting to sound like a dork! ;D
Nurse Julie:
Yes George, the manual is incorrect.
Bryanj:
I have always turned clockwise from points end which puts cam chain slack in the rear run where the adjuster is, doing it in workshop you tend to do all the settings at same time, easy when you are doing several a day.
Also i ignore that table, take cylinders 1 and 4 check which cylinder has the rockers both moving, exhaust closing inlet opening and you adjust the other one.
To try and explain it easy if 1 and 4 are both at tdc (T mark aligned) one cylinder is at tdc compression and is the one you adjust theother is at tdc exhaust where both valves are open
Athame57:
Any tappet to be adjusted will be sat in it's highest position be it inlet or exhaust, yes? Can I simply go to each in turn and adjust when they get there? If so a bit time consuming but easy to understand, that's my issue, being led one way then the next.

I suspect that on the internet they are standing on the left of the bike where number 1 cylinder is and clockwise from the points end is counter clockwise looking at the alternator end if you get my meaning?
