748 chain length

Hi, I've just bought a new jt sprocket carrier and intend to run both 14/40 and 14/42 combinations to see what I like best. However is this possible to do with the same length chain and what length shall I order. I think it will be a 98 link chain but I could do with some advice. Thanks

The difference between the two options is almost 9mm in the wheel position, so only just over half a link in the top and bottom chain run.
so 98 will probably be OK with both, but as I prefered to run my 748 on as long a wheelbase as possible I would probably go for 100 link, at least that way you always have the option to shorten the chain

Thanks, I didn't realise that there is that much adjustment.

Fair bit of adjustment, only thing is when you adjust the eccentric that much it alters the ride height so then you have to adjust the rideheight bar. So get a reference before you start.
some use centre of the spindle to middle of the exhaust can or a sticker on the seat unit
