The star bit bolts come out nicely if the engine is cold... The only shield that was annoying when hot during a ride was the rear one. I keep the forward pegs on the middle setting.Its a T25 torx bit required to remove the 3 heat shields from the header. They are threadlocked so if you have not got replacement screws from Triumph, apply some High temp threadlock when reassenbling and tighten to 5Nm.
Moving them back one notch helps, but the heat wrap keeps it just warm when riding. Never rode anything but the GT so dont know if its even necessary on the R model.
