The one i have bought looks a copy of the Trusty cover.

So being as there are differing opinions on wether the hole should be plugged or not can anyone tell me if leaving the hole unplugged will damage anything inside?

I am using a Dep expansion pipe which is great up top, almost gives it a motocross feel, but is lacking abit of grunt down low, compared to the messico pipe i was using before, hence the powervalve cover.
