Count pins on timing chain

[sacruickshank]

While checking the valve shim clearance on my 1983 GS450L the timing chain slipped as few teeth, so now I have to reset it.

I have the clymer manual, which lists 18 pins in between marks 2 and 3 as the correct timing. Unfortunately the images are a little vague. Since the 2 and 3 marking arrows are at the valley of a tooth are you supposed to include the pins in those valleys as part of the 18? Or do you exclude those pins that fall right at the markings?

Put another way, is it 18 pins, including the pins ate the markings or 18 pins between the markings, which would be 20 pins including the ones at the marks

Thanks,

Steve

The diagram suggests the arrow points to the pin...

I have never seen a variation to the above interpretation. Pin 1 is at the exhaust cam arrow. Pin 18 (or 20 for the 850) is at the inlet cam arrow.
This always makes me think and double check because I can't get my head around it.

Thanks all, I'll adjust as needed.

I saw the picture , but the use of the word "between" threw me. Plus the arrows are just barely after and before the pins, at least by my eyes.

"18 chain pins (GS450 models) are between arrow No. 2 on the exhaust cam and arrow No. 3 on the intake cam as shown in Figure 29 or Figure 30."

An unambiguous wording would have added, including the pins at arrows 2 and 3.
