Some different experiences here to be sure. I'm 6' 2" with 34" inside leg and work OK on an LM1 with standard pegs, with my knees just over the heads. I actually bought some Tarozzi rearsets, because I thought they looked cool and then found that they lowered my knees onto the heads, so I gave up on them. Curiously, whereas I've found the seating position on a R100RS a bit 'folded in the middle' with standard pegs, I've always felt quite comfortable on the LM. My V7 Sport is running S3 pegs, courtesy of a previous owner, and they may help, because that's also no problem in normal riding.
One thing that I can say, is that on both bikes, if I go over a big bump, I will get a nasty bang on my left knee if I don't get it out of the way in time.
