Cam Chain Adjusting
Bryanj:
OK there are many different methods in Honda manuals for adjusting the cam chain but here is a method i have used for 30+ years which works as long as the tensioner is operating as it should and the camchain still has useable life.
(1) Find a method of turning the crankshaft, this can be
(a) Kickstart
(b) spanner on nut on end of crank
(c) rotating back wheel in gear
Or any other none destructive method you can find.
(2) Put pressure onto your turning method so that the engine is just about to turn but not quite turning.
(3) This is the difficult bit, Whilst holding that engine possition loosen the cam chain adjuster locking bolt/nut and re-tighten. That is the bolt/nut that actualy locks the tensioner not the one that stops the lock undoing!
If the chain is stilll noisy try again in a different position, if its still noisy either the adjuster is siezesd or at its limit and/or the camchain needs replacing.
Have fun.
;D

Does this work with the engine in any position? (and no, I don't mean "upside down on the floor!)
So all this TDC on #1 is a load of ****, just try different places until it's quiet?
Dave M:
I always thought that it should work in any position as long as the chain opposite the tensioner is under tension with no slack in it.
The important thing, as Bryan says, is to get the engine just on the point of turning so all the slack is on the tensioner side and then release the tensioner.
Job's a good 'un. Thanks for that Bryan.
Bryanj:
Steve, if you want to do it upside down on the floor then yes it will work!---just be careful you dont strain anything the dearly beloved wants to keep!!!
As Dave sez the IMPORTANT bit is to get the engine just about to turn so that all the slack is on the tensioner side, this is what Honda are trying to do by specifying different positions of the crank, i just find it easier with a spanner

3 hands help too!
