never had one but I believe its the same chaincase as the first gen 6 and 700s. same target rpm too, 8100.
theres a gear chart in here that should work on yours, make sure you scroll down to the right chaincase - 7.05 center distance (97-98 domestic twins), its a few pages down, right after the older chaincase chart

not sure whats in yours now but id probably shoot for around 2.2 gear ratio, or 18/40 with a 68 pin chain on the chart.
we tried that on a 700 down here at 3000' and found it a hair too low with a SLP pipe. SLP single pipe on those motors pulls stock gearing fine in the mountains.
