You can get that information from the stock gearsets...
I would offer 2 configurations myself, but you probably would be ok in offering a 3.29 ratio set using 2 35 tooth gears.
Remember that factory chains are dual 1/2 inch chains, so you really REALLY need to do alot of R-D on these new 1inch chains to get 4x the strength out of the same 1inch wide package.... I could probably find someone to adapt a 1 inch bike chain to fit onto there, but i highly doubt it would be strong enough to outperform stock.
Long story short.. just because you can find someone to make a "chain" in a 1 inch wide package, it could easily end up like the 15/16 chains did when people upgraded from the 7/8 inch chains... People found out due to the chain design that the 15/16 was indeed weaker than the 7/8.
