    42T Sprocket, Chain Question

    Bought a 42T rear sprocket and will I need to shorten the chain?

    Part Deaux: If I do shorten the chain and decide to go back to the stock 45T will it work?

    Thanks in advance :028:

    You can "just" get away with removing two links, l have a 42t on mine and it's now in the middle of the adjustment.... and when l refit the stock 45t for track use the adjustment is very close to the front of the swingarm slot.

    Try it without removing any links, but l fear you'll run out of adjustment towards the rear as the chain stretches with the 42t on there.

    Should have asked this in my post: I was told removing just one link isn't a good idea, it should be two. Is this accurate or intraweb jibber jabber? Gotta be careful these days regarding info.

    You cannot remove just one link, each end of the chain then becomes two males or two females if you do, kinda hard to reconnect the ends.  :001:

    Gen-2 has a taller 4th, 5th & 6th gear than the Gen-1....which negates the need on a Gen-2. I've not heard of anyone fitting a 42t on a Gen-2.
