    Hi.
    My 1967 G15, in restoration, has all missing the primary system.
    It is not a great problem because i have a lot of parts from my previous P11s and N15 rebuilt.
    But mine N15/P111s have 21 theet sprocket with 68 chain links.
    Roy Bacon book says G15 has 22/23 primary sprocket theet.
    Please, can i mount 21/68 but, in case of 22/23, how many should be the links?.
    Thank you.
    Piero

    Piero,
    My parts book for the G15's / N15's only lists the 68 link primary chain. It lists 21 toothed engine sprocket as standard with 22t std on the G15Mk2 and G15CSR. I would guess that there is enough adjustment to use either. The parts book lists 17 to 21t engine sprockets as an alternative to the ones fitted from the factory. Hope this is of some help.
