The revs at 70 on both are around 3300 I can not tell on the ironhead as it's in kph.
And off the line in first it's never any trouble just rev to around 1500 rpm and feed out the clutch, never stalled it yet?
When going slow in 4th in town I can get right down to 1150rpm which is about 31 mph. If I use 3rd it's to much noise and then the police will pull you.

enginetorque,
transmission mainshaft roller bearing is lubricated by gravity from a gutter located on the roof of the trans case (right crankcase half). This gutter fills by splash and drains oil down through a hole to the outside of the rollers between the bearing and the oil seal. Check to see that this hole is clear and that the seal or the bearing outer race (roller cup) is not obstructing it.

As long as it's a late 84 with the alternator behind the clutch, then hell yes it'll bolt right in. You can also just buy the late 84-early 86 clutch gear and countershaft gear.

They have it cheap as hell on ebay right now, just need the 1958-1986 27T countershaft gear.

This may be the wrong forum, but y'all really seem to know your stuff. Has anyone ever tried/ is it possible to run a four-speed tranny in an '03 sporty. Also, is it possible to get a kicked transmission to turn over an Evo engine?

No, and why would ya want to?? As far as kicking an Evo, I don't see why not, same compression as the Ironhead, but their is no way to install a kicker in any Evo, or any 80-85 Ironhead for that matter.

Lets say you have a bike that was converted to belt drive. How would you figure the correct ratios needed then? Are the teeth count the same on the secondary drive sprockets?

Also, are these the only parts you need to replace in the transmission?:

Countershaft Drive Gear:35695-58
