If you are keeping the deep track gear it for 100 mph with the stock clutching it will run about 105

Totally sucks except for ditch banging though.
100 mph gears still pull real hard.

So something like a 23/39 with a 74 chain?

I would think somewhere around 22/41 if that combo fits an IQR cc. Thats a 1.86 ratio thats good for 96mph at 8250

With your stock 76p chain 22/43. 23/43. And 23/43 are options .If you have a 74 p chain 22/40 would work.
On a side note,tune it to 8500 rpms or 8750 if its race ported or 2013 and newer cylinders.The 8250 rpms recommended back then never really worked.
