I am also 6'4", but with a 36inch inseam and 39"arm length at 240 lbs. I am all arms and legs.
Raising the pegs helped me. I have a BMS(Legendary seat- The owner of Legendary precviously made the saddles for BMS). I had Fastway pegs in the lower position. I started to get a sharp pain under my thighs. I originally thought that the area where the saddle curved in contributed to the pain. I then realized that I higher saddle and lower foot peg angled my thighs to where it was more comfortable to sit forward on the seat. I wrote to Legendary, and they told me to come in to fix it. Just before my ride, I switched my pegs to the high position.
Legendary destiched my saddle and pulled the cover more to have less of an edge. I took her for a ride and it solved the issue. These bucket or tractor design seats should account for leg angle. My thighs had to be more of a parallel position for the flat seat so I did not get the fatigue. The combination of having the pegs at the normal position with the saddle adjustment made it more comfortable.
If I raise my toes a little on the pegs, my knees are right in the pocket of the tank before it bulges out. I can brake hard and not have to squeeze my legs as hard since I have leverage of my knees against that groove to prevent me from sliding forward.
I followed the threads that said lower pegs with higher bars and I made those changes, but I found that did not make it better for me. I went from ADV high bars back to ADV low with Fastway pegs in the high position. If I stand, I am more in the Attack position rather than straight up.
I do not need touring pegs. For relief on long distance, I can sit on the pillion seat and still reach all my controls. I also get a great arm stretch! Ha I have 86K miles on my S10 and have been making changes throughout her life and this is the setup where I found best for ME.
Unfortunately, you cannot buy something to test and send it back. This has been an expensive process and learned that this is all individual. I go through this with clothing. It seems designers through all brands have sizes accurate from S to XL. XXL and above is left to interpretation and all over the place. If you are tall and athletic... forget about it.
