Finding TDC for an idiot

[gggGary]

intake goes down, comes back up then another 1/2 turn of the crank is the tdc you want.
You are at TDC AFTER the compression stroke.

Check, are the other cylinder valves loose now?

I'll check it'll take a few minutes I haven't removed the covers yet

 

[Mikey]

All valves are rock solid after rotating ccw wait till intake barely starts to close line up marks no slop at all neither intake or exhaust

Don't mean to insult you Mikey, so don't take offense....
Intake valve is the one in back by the carbs.
Ccw means hold the wrench high and push (pull) it forward towards the front wheel and down.

We on the same page?

Don't worry about "barely" closed. Once it's "fully closed" you still have about 120-130° of rotation to go yet.
The idea is to make sure the intake is the valve operating and then rotate to TDC from there.

 

[Mikey]

No change on right side but left side has exhaust at 10 thousands intake and exhaust both have that can be moved slightly
As in I know I can adjust them

READ that service bulletin I posted, it applies to your 73 as well.

So you saying that this 73 will be at 003 and 006
I guess I had to look at the service bulletin date and yep it's from 72
Aren't the newer bikes at .004 .006 exhaust
Why the difference I thought the older bikes had a larger exhaust clearance
Suppose they re thought the spec's

Nevermind found the change option next to the report button

 

[Mikey]

Bulletin saved and printed
I've got a set of ignition wrenches headed this way as that square wrench that came with the OEM tool kit just doesn't cut it
Thanks for being patient with me !!
