Exhaust wrap, good or bad??? on Blata replica air cooled

[RD RACING]

i would reccomend only covering certain areas such as insulating plastics base of fuel tank ect, there is no need to insulate the pipe, especially for the reason of keeping the head cooler, remember heat rises and surely your pipe isn,t touching the head. there is plenty of air flow around a motor bike engine, much different to a car running a turbo.
