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.

Know where I can find a good deal on a Polaris Pit Coat? :lol3:
Last year there was one at the Salvation Army in Petoskey. I could not get myself to buy the ugly dress. It was a whole 20 bucks

Would it do the same with a 440 liquid? I’m curious to what gearing has a good low end but also has the top end for trail riding.
