Ok I need a spot of help...I have the factory manual and the aftermarket manual. I CANNOT find the spec for timing chain stretch limit, i.e. how many pins you measure and what it should be on a 1978 GS750. Can someone point me in the right direction...I don?t know how many miles are on this motor and it wasn?t running when i got it in. Also tried a search here and couldn?t locate the info...thanks for any help! If you have the factory manual what page is this info on? I looked twice then I had some beers and looked again ands still didn?t find it.

My 850 manual says just about the same thing. :-k
It calls it the "20 pitch length", not 21. Theh difference is whether you number that first pin "0" or "1".
If you place your caliper on a pin and call that one "0", you will measure the distance to pin "20". You will be measuring 20 links of the chain.
If you place your caliper on a pin and call that one "1", you will measure the distance to pin "21". You will be still be measuring 20 links of the chain.
I mention this because this is similar to a common problem when setting cam timing.
