I have been trying to find it in rule book and havent and that usually means you cant.....but i wanted to make sure if you can or cannot take off anything with the pair system....just wanting to make sure so cant get DQ
I've checked on this question before. Pair valve can be removed and is considered as part of an exhaust system modification. Modification to hook the Pair valve to the crankcase is illegal. It performs crankcase scavanging and therefore is a performance advantage.
