Guys I also felt the hot right calf affect when I first picked up my bike, but made the assumption that some of the heat was radiating through the metal of the air filter cover (?) , as it was getting pretty warm to touch.
But now I have the "new" pipes on that Peter Turner modified for me, the heat is not as bad. I haven't touched the Cat in the header pipe.
I went for a 350km run yesterday , and I didn't notice the hot right leg at all!
It was a fantastic day to ride , clear blue sky and about 24 degrees with a light SW breeze.
It does get much warmer up here in QLD so I will let you know how it goes as summer sets in.
I will post a couple of picks of my pipes in the next day or so , and try to show the new baffles. The pipes externally are the original equipment , but you cant see the core pipe as easy . But they sound great!!!
They still don't look as good as Glens pipes though!!!! They are awesome !!
