Although initially I fitted the heat blanket, I've now taken it off. The heat blanket causes quite a lot of "extra" heat to rise up in front of the passenger, between the front and rear seats, compared with not fitting the heat blanket. And I quite like the rider's seat being a little warmer.
With the heat shields, there is no noticeable heat hitting the riders legs, but there is "extra" hot air directed onto the passenger's lower legs compared with not having the heat shields.
I measured the contact temperature of the carbon heat shields after a long run today. The left hand shield was 75 C / 175 F, the right hand shield was 60 C / 140 F. Without the heat shields this would be the air temperature hitting the rider's legs.
