i have removed the triangles and have an akra map, so rich A/F mix. it has made a noticable diffrence to the "on the seat" dyno. But when it warms up above 30deg C the engine passes more hot air through there. Gets a bit sluggish, but if you ride the hills and with a crisper air temp, its an easiest mod to get more go..!!
You will just risk getting water in the TB's at worst.
You will also notice this awsome induction noise..!!
But once you do this you will be saving your penny's for a motobox like I am..!!
