Yeh, there was some funny stuff in this thread
I wish I had another year of high performance track work under my belt... sigh.
Just on the wheel diameter thing, if you've got a constant throttle, therefore a given amount of fuel going into the engine, the bike MUST slow down as you tip it in. Discounting the cornering friction forces side of things, the bike would have to slow down anyway because the engine revs aren't changing, but the rear wheel diameter has effectively reduced... so you cover less distance for each revolution. See? The speed you eventually settle down to depends on how far you lean. Conversely, for a constant throttle, you'll start to speed up as you stand it up.
The flip side is the one you mention, that if you hold the (true) velocity steady as you're tipping in, the revs must go up as the lean angle increases. A smaller wheel needs to go around more often for the same speed, so for a given lean angle and speed, you'd need more throttle than if you were travelling in a straight line.
As to what would happen if you had a huge flat play area, marked out a large diameter circle, countersteered the bike into a known and constant lean around this cirlce and kept going round and round rolling it on... You'd eventually bump up against the rev limiter in 6th {that would be near 300km/h on my bike! Yikes!} and the sudden automatic "roll off" could be a bit exciting!!
Before that happens, it'd be better to gradually reduce the roll on till you eventually stop and hold a steady throttle position. There'd be some weight transfer forward as the bike gently sorted out it's dynamic situation until it settled into a steady contstant velocity. We've been well taught to roll on once the turn has been finished in order to put the bike into it's ideal traction picture, but there's nothing to say that a bike wouldn't happily keep turning a corner with a neutral weight transfer picture, i.e. constant velocity, instead.
Thoughts????
